AI Phone Answering Service Cost Breakdown
An AI phone answering service can start with a free tier or a paid plan around $25/month, but its true cost depends on whether it bills per call, minute, unique caller or add-on. As of September 2026, Trillet is $49/month for 150 voice minutes and $0.20 per extra minute; AIRA and Upfirst start at $24.95 for 30 calls with $1.50 per extra call; Smith.ai offers a free AI tier and Pro from $150 for 75 calls. An AI receptionist is a phone-focused kind of voice AI agent, not a synonym for every voice agent, so compare the actual answering workflow. This breakdown shows the monthly math at realistic volumes, then checks SMS, forwarded-call and feature costs that a base fee can hide.
The advertised price is not always the full cost. Overage rates, per-call billing, carrier forwarding, per-message fees and feature gates can change the result. The figures below reflect available vendor pricing checked in September 2026 and separate direct vendor charges from scenario assumptions.
If your question is simply which service costs the least, the cheapest AI phone answering services compared ranks them by real monthly cost. If you want to understand why the billing models differ in the first place, see per-minute vs per-call vs credit pricing.

How Much Does an AI Receptionist Cost, and Is It the Same as an AI Voice Agent?
An AI receptionist or AI phone answering service handles inbound calls, speaks with callers and can book, route or summarize them. "AI voice agent" is broader: it can also describe outbound or internal workflows with different pricing. A small business may spend nothing during a limited free tier, $25 to $150 on many published self-serve plans, or more when usage rises. Trillet's direct receptionist is $49/month for 150 inbound voice minutes and $0.20/minute beyond that as of September 2026; SMS messages and any carrier forwarding charges are separate. Do the math at your own call count before assuming per-minute or per-call wins.
What Are the Main Pricing Models for AI Phone Answering?
AI phone answering services use several pricing structures as of September 2026, each with different cost implications. The billing unit determines whether longer calls, more calls or more unique callers drive your bill.
These are the four models and what each does to your monthly spend:
1. Minute-Bucket Pricing You pay a flat monthly fee that includes a set number of minutes. Overages are charged per minute.
- Example: Trillet charges $49/month for 150 minutes, then $0.20/minute after that
- Example: Dialzara charges $29/month for 60 minutes, then $0.48/minute after that (dropping to $0.35 on higher tiers)
- Best for: Businesses with predictable call volumes
2. Per-Call Pricing You pay for each answered call regardless of duration, so a 30-second call and a 6-minute call cost the same.
- Example: AIRA and UpFirst both charge $24.95/month for 30 calls, then $1.50 per additional call (dropping to about $0.70 on higher tiers)
- Example: Smith.ai's AI Pro starts at $150/month for 75 calls, then $2.50 per extra call on that tier; it has a separate free AI tier, larger paid call blocks and an optional live-agent network
- Best for: Businesses with fewer but longer calls, provided the included-call allowance fits
- Watch out for: Many short calls can exhaust the allowance faster than a minute bucket
3. Unique Caller Caps Unlimited minutes but a cap on how many different callers you can receive.
- Example: Goodcall charges $79/month for 100 unique callers, then $0.50 per additional unique caller
- Best for: Businesses with repeat callers (existing customers)
- Worst for: Businesses with high new-caller volume (lead generation)
4. Tiered Minute Plans With Feature Gating A monthly fee for a block of minutes, but key features like appointment booking are locked to higher tiers.
- Example: Rosie charges $49/month for 250 minutes; direct calendar booking starts on its $149 Scale tier, while its $49 Professional plan can send appointment links by text. Larger 1,000- and 2,000-minute tiers cost more.
- Best for: Businesses that want simple per-month budgeting and only need basic answering at the entry tier
- Worst for: Businesses needing appointment scheduling or integrations, which push you to a pricier tier
How Much Does Each AI Phone Answering Service Actually Cost?
Real-world costs depend on both call volume and duration. These examples use published starting tiers as of September 2026, exclude taxes and ancillary charges unless noted, and should be recalculated if a higher tier is cheaper at your volume. For broader context, see the complete AI receptionist guide.
We calculated costs for three business scenarios:
- Light usage: 30 calls/month, 3 minutes average (90 total minutes)
- Medium usage: 50 calls/month, 3 minutes average (150 total minutes)
- Heavy usage: 100 calls/month, 3 minutes average (300 total minutes)
Trillet Pricing
| Usage Level | Base Plan | Minutes Used | Overage | Total Monthly Cost |
|---|---|---|---|---|
| Light (90 min) | $49 | 90 of 150 | $0 | $49 |
| Medium (150 min) | $49 | 150 of 150 | $0 | $49 |
| Heavy (300 min) | $49 | 150 + 150 overage | $30 | $79 |
Trillet includes 150 inbound voice minutes at $49 with $0.20/minute overages. It supports SMS follow-up and email call summaries, but SMS usage costs $0.02 per message, or $0.01 with optional bring-your-own Twilio/Telnyx telephony. Text confirmations and reminders go out from a Trillet number registered for A2P 10DLC (the US carriers' registration for business texting), so there's nothing for you to register. It can capture a requested callback time for owner follow-up; that is not an outbound campaign entitlement.
Dialzara Pricing
| Usage Level | Base Plan | Minutes Used | Overage | Total Monthly Cost |
|---|---|---|---|---|
| Light (90 min) | $29 | 60 + 30 overage | $14.40 | $43.40 |
| Medium (150 min) | $29 | 60 + 90 overage | $43.20 | $72.20 |
| Heavy (300 min) | $29 | 60 + 240 overage | $115.20 | $144.20 |
Dialzara's $29 entry tier includes 60 minutes and charges $0.48/minute after that. At 300 minutes the entry-tier arithmetic is $144.20, not $349; an intermediate or larger Dialzara plan may be a better fit if its allowance covers your pattern. Dialzara markets voice, optional SMS and chat offerings, but those may carry separate charges. For health information, verify the exact agreement and covered workflow rather than inferring HIPAA eligibility from a plan label.
Smith.ai Pricing
Smith.ai offers AI reception with an optional live-agent network, plus separate human-first plans. As of September 2026, its AI Pro starts at $150/month for 75 calls, then $2.50 per extra call on that base level. Higher Pro blocks have different rates, and Enterprise starts at $500 for 300 calls. Smith.ai's current AI page lists scheduling in the Free feature set, so do not automatically add an old booking surcharge to every AI plan. The table uses base AI Pro without optional live-agent fees.
| Usage Level | Base Plan | Calls Used | Overage | Total Monthly Cost |
|---|---|---|---|---|
| Light (30 calls) | $150 (AI Pro) | 30 of 75 | $0 | $150 |
| Medium (50 calls) | $150 (AI Pro) | 50 of 75 | $0 | $150 |
| Heavy (100 calls) | $150 (AI Pro) | 75 + 25 extra calls | $62.50 | $212.50 |
Smith.ai's AI Pro starting price remains higher than the other paid entries in this table, but its free 25-call tier is a real alternative for testing. Human escalation can be configured on AI plans, with its own terms, so do not assume that the $150 base automatically covers every live-agent scenario. For businesses needing only routine inbound answering, compare that premium against the value of the human option and deeper workflows. The Smith.ai alternatives guide explains the model in more depth.
Goodcall Pricing
| Usage Level | Base Plan | Unique Callers | Overage | Total Monthly Cost |
|---|---|---|---|---|
| Light (30 callers) | $79 | 30 of 100 | $0 | $79 |
| Medium (50 callers) | $79 | 50 of 100 | $0 | $79 |
| Heavy (100+ callers) | $79 | 100 + overage | $0.50/caller | $79+ |
Goodcall charges $79/month for 100 unique callers as of September 2026, with $0.50 per additional unique caller and a $249/month top tier covering 500 callers. The caller-cap model works well if you have repeat customers, since the same person calling ten times counts once. New lead-heavy businesses, where most callers are first-timers, risk hitting the cap and paying per-caller overages.
Hey Rosie Pricing
| Usage Level | Included Minutes | Base Plan | Total Monthly Cost |
|---|---|---|---|
| Light (90 min) | 250 minutes, basic answering | $49 | $49 |
| Medium (150 min) | 250 minutes, basic answering | $49 | $49 |
| Heavy (300 min) | 250 minutes, then excess usage | $49 | Confirm current excess-minute rate |
Rosie charges $49/month for 250 minutes as of September 2026, while direct calendar booking starts at $149/month on Scale. Its $49 plan can send appointment links by text and includes a website chat widget; that is useful but not the same as booking directly during the call. Rosie publishes 250-, 1,000- and 2,000-minute tiers rather than an unlimited-minute plan. For more on billing claims, see what unlimited AI receptionist minutes actually get you.
AIRA and UpFirst Pricing
AIRA and Upfirst publish matching entry per-call prices as of September 2026: $24.95/month for 30 calls, then $1.50 per additional handled call, dropping to $0.70 on 600-call Scale plans. They also describe spam filtering, so do not assume every wrong number or blocked robocall is billed. A long handled consultation and a short handled inquiry use the same call unit.
| Usage Level | Base Plan | Calls Used | Overage | Total Monthly Cost |
|---|---|---|---|---|
| Light (30 calls) | $24.95 | 30 of 30 | $0 | $24.95 |
| Medium (50 calls) | $24.95 | 30 + 20 overage | $30 | $54.95 |
| Heavy (100 calls) | $59.95 (Premium) | 90 + 10 extra calls | $10 | $69.95 |
The $24.95 entry price is low, but 100 calls a month favor a higher tier over Starter overages: Premium's 90 included calls plus 10 at $1 equals $69.95, versus $129.95 if 70 extra calls are billed at Starter's $1.50. Upfirst advertises in-call texting and a BAA on Custom, so calling it voice-only or broadly non-compliant would be inaccurate. If PHI is involved, confirm the BAA and plan rather than assuming entry-tier eligibility. The per-interaction pricing guide covers other usage traps.
What Hidden Costs Should I Watch For?
The advertised price is not always the full cost. Check these common extra charges before comparing plans.
Feature Add-Ons Some platforms charge extra for features that should be standard:
- HIPAA-covered workflows: ask whether the vendor signs a BAA and what tier or add-on is required
- SMS/text messaging: check per-message fees, bundled credits and whether two-way replies are included
- Call recording: confirm retention, consent settings and whether storage or access costs extra
- CRM integration: distinguish a native connector from DIY API or a paid managed integration
Trillet's $49 D2C plan supports SMS follow-up and email call summaries, but each outgoing SMS is charged separately. It has native calendar sync with Google Calendar, Cal.com (including Outlook through Cal.com) and GoHighLevel Calendar; CRM connections are DIY through the platform API, not a managed native D2C connector. Trillet's public terms do not permit HIPAA PHI on D2C; BAAs are available for Agency and Enterprise workflows under an applicable Order Form.
Overage Rates The difference between published overage rates creates cost disparities as of September 2026:
- Trillet: $0.20/minute
- Phonely: confirm the Starter excess-minute rate at checkout; its pricing sections conflict on plan details
- Frontdesk (formerly My AI Front Desk): 25 credits per extra voice minute at $0.01/credit, or $0.25/minute; its Business plan also includes 1,000 monthly overage credits shared with other usage
- Dialzara: $0.48/minute on the entry tier (140% more expensive)
- AIRA and UpFirst: $0.70 to $1.50 per call, which can exceed $1/minute on short calls
- Smith.ai: $2.50 per extra call on the base $150/month AI Pro tier; larger tiers differ, and optional live-agent involvement has separate terms
At 100 extra voice minutes, the difference between Trillet ($20) and Dialzara's entry rate ($48) is $28/month, or $336/year if that pattern repeats for twelve months. SMS, number rental and carrier forwarding can still change the full bill. Per-call services need an estimated count, not a conversion from minutes alone.
Setup Fees Most AI phone answering services don't charge setup fees, but some enterprise-tier services do. Always confirm during signup.
Annual vs Monthly Billing Some platforms offer discounts for annual billing (10-20% off) but lock you into a 12-month commitment. Trillet offers monthly billing with no long-term contracts.
Phone Number Costs Number policies vary. Echowin lists $10/month per number; Phonely's free tier lists a number; Trillet customers can keep their existing business number through forwarding without buying new hardware. Ask about new or toll-free numbers, porting, and charges for the forwarded leg from your carrier.
How Do AI Phone Answering Costs Compare to Human Receptionists?
AI phone answering can cost less than a staffed desk for routine inbound coverage, but it does not provide the same judgment, walk-in help or service quality. Compare like-for-like hours and responsibilities.
In-House Human Receptionist Costs
- Example salary budget: $35,000 to $50,000/year, or about $2,917 to $4,167/month before payroll costs; use a local pay benchmark for your market
- Example benefits/payroll allowance: 20% to 30% on top, depending on location and employment terms
- Training: budget time and money for policies, scheduling systems and customer-service quality
- Coverage: a standard full-time schedule is not 24/7, but a human also handles walk-ins and exceptions
- Illustrative budget: roughly $3,500 to $5,500/month before any after-hours staffing
Outsourced Human Receptionist (Ruby, Nexa, etc.)
- Entry plans: Ruby publishes limited-minute packages from about $250/month; Nexa's exact price is quote-gated, so request a current proposal
- Higher minute blocks: Ruby's 200-minute plan runs about $720/month and its 500-minute plan about $1,725/month
- Per-minute overage: published rates are sales-gated, but third-party estimates put human services well above AI per-minute rates
- Total: published Ruby tiers span roughly $250 to $1,725/month; other providers need a current quote
AI Phone Answering Service
- Entry plans: limited free tiers exist, and the paid examples in this guide start at $24.95/month for 30 calls; Trillet's different 150-minute plan starts at $49/month
- Heavy usage: model overages, messaging and telephony rather than assuming a fixed range
- 24/7 availability is offered, but networks and services can still fail
- Example: Trillet's subscription plus voice usage at 300 minutes is $79/month, before SMS and carrier charges
In this example, AI is much cheaper for routine phone coverage, but it is not a one-for-one replacement for a human receptionist's judgment or in-person work. Put a human escalation path beside the cost estimate, especially for complex or urgent calls.

What's the ROI of AI Phone Answering?
The return on investment comes from captured calls that would otherwise go to voicemail or competitors.
The Cost of Missed Calls Start with your own phone logs rather than generic missed-call statistics. Count calls that reached voicemail, identify which were qualified opportunities, and measure how many turned into paying customers after follow-up. Without those inputs, an ROI percentage would be a guess.
ROI Calculation Example: Home Services Business
- Monthly missed calls before AI: 30
- Average job value: $300
- Close rate on answered calls: 30%
- Illustrative opportunity, if every missed caller was a qualified lead: 30 × $300 × 30% = $2,700/month
- AI phone answering cost: $49-79/month
- This is an upper-bound scenario, not realized ROI; subtract calls that would not have converted and the cost of delivering the jobs
If the AI captures only 10% of those 30 missed calls and the assumed 30% close rate holds, expected extra jobs are less than one per month. Track actual booked and completed jobs before claiming payback.
ROI Calculation Example: Professional Services
- Monthly missed calls before AI: 15
- Average client value: $2,000
- Close rate on answered calls: 20%
- Illustrative opportunity, if every missed caller was qualified: 15 × $2,000 × 20% = $6,000/month
- AI phone answering cost: $49-79/month
- This is an upper-bound opportunity, not a measured ROI; referral quality, capacity and fulfillment costs determine the outcome

How Do I Choose the Right Plan for My Business?
Selecting the right AI phone answering plan depends on your call volume, call duration, and feature requirements.
Step 1: Estimate Your Monthly Call Volume
- Check your phone records for the past 3 months
- Count total incoming calls (not just answered)
- Calculate average call duration
Step 2: Calculate Your Minute Usage
- Multiply calls by average duration
- Add 20% buffer for growth and seasonality
- Example: 50 calls x 3 minutes x 1.2 = 180 minutes/month
Step 3: Compare Total Costs Using 180 minutes/month (about 60 calls at 3 minutes each):
- Trillet: $49 base + 30 min overage x $0.20 = $55/month
- Dialzara: $29 base + 120 min overage x $0.48 = $86.60/month
- AIRA or Upfirst (60 calls): the $59.95 Premium plan with 90 calls is cheaper than Starter plus 30 extra calls at $69.95
- Smith.ai (AI Receptionist Pro): $150 base covers 75 calls at the entry Pro tier = $150/month for this scenario
Step 4: Factor in Required Features List non-negotiable features:
- Appointment scheduling? (Some platforms lock this behind higher tiers)
- SMS/text follow-up? (Often an add-on)
- CRM integration? (Check compatibility and cost)
- HIPAA PHI? (Confirm BAA availability, covered workflow and any higher tier or add-on)
Trillet's $49 D2C plan includes supported calendar booking and SMS follow-up capability, but SMS messages are charged separately and the plan does not authorize HIPAA PHI processing. Calendar sync is native out of the box; CRM connections are available on a DIY, self-serve basis through the platform API. For PHI, ask Trillet about Agency or Enterprise with an executed BAA and applicable Order Form.
Comparison: AI Phone Answering Service Costs 2026
The table summarizes available entry pricing and overage rates as of September 2026. Channel scope and regulated-workflow prerequisites matter because the cheapest base fee may not cover the work you need.
| Service | Entry Price | Included Usage | Overage Rate | Multi-Channel | HIPAA | Best For |
|---|---|---|---|---|---|---|
| Trillet | $49/month | 150 minutes | $0.20/min; SMS extra | Inbound voice, SMS follow-up, email summaries | No PHI on D2C | Supported booking and backup |
| Dialzara | $29/month | 60 minutes | $0.48/min ($0.35 higher tiers) | Voice, SMS, chat | HIPAA marketed; confirm BAA and covered workflow | Light usage only |
| Frontdesk (formerly My AI Front Desk) | $99/month voice plan | 200 minutes + 1,000 shared overage credits | 25 credits/min ($0.25), after available credits | Voice, chat, SMS, email drafts | Verify agreement | Broad workflow bundle |
| Rosie | $49/month | 250 minutes | Confirm at checkout | Voice, text links, web chat | Verify agreement | High included minutes |
| AIRA / Upfirst | $24.95/month | 30 calls | $1.50/call ($0.70 higher tiers) | Voice; Upfirst in-call texts | Upfirst BAA on Custom | Longer, lower-volume calls |
| Goodcall | $79/month | 100 callers | $0.50/caller | Voice | Verify agreement | Repeat customers |
| Smith.ai | Free 25 calls; Pro from $150/month | 75 calls on base Pro | $2.50/extra call on base Pro | Voice, optional live-agent network | Verify agreement | Optional human escalation |
Note: Phonely offers a free 100-minute tier, and Smith.ai offers a free 25-call tier. Frontdesk's old $20 Basic tier is not shown on its current pricing page, so it is excluded from the live voice comparison. Phonely's page conflicts between 200 and 250 Starter minutes; confirm at checkout.
Frequently Asked Questions
What is the cheapest AI phone answering service?
Phonely and Smith.ai publish free AI tiers; among the paid entries discussed here, AIRA and Upfirst start at $24.95/month, followed by Dialzara at $29/month. Cheapest entry price is not always cheapest total cost: compare the number of calls or minutes included, the extra-unit rate and any messaging or number charge. Trillet is $49/150 minutes with $0.20 per extra voice minute, but a different tier may win at your specific volume.
Are there setup fees for AI phone answering services?
Trillet's direct AI receptionist has no setup fee. Other vendors vary by plan, and a custom enterprise deployment may have implementation charges. Even with no setup fee, ask about SMS, phone numbers, carrier forwarding, integrations, taxes and usage overages.
How much can I save compared to a human receptionist?
AI can reduce the cost of routine inbound phone coverage compared with hiring a full-time receptionist, but the saving depends on volume, local wages and the tasks a human currently handles. The $3,500–$5,500 staff example above is illustrative, not a universal market rate; Ruby publishes human answering tiers in the hundreds to thousands per month, while Nexa requires a quote. Keep a human path for exceptions and compare the total service, not just subscription fees.
Do I need to pay extra for appointment scheduling?
It depends. Trillet's D2C plan supports Google Calendar, Cal.com (including Outlook through Cal.com) and GoHighLevel Calendar. Rosie can send appointment links from its $49 plan but reserves direct calendar booking for its $149 Scale tier. AIRA advertises CRM/Zapier links and Upfirst lists direct calendar booking even on Starter, so neither should be dismissed as voice-only. Test the exact scheduler you use.
What happens if I exceed my included minutes?
You may pay an extra-unit charge or need a higher plan. As of September 2026, Trillet charges $0.20/minute, Dialzara's entry tier lists $0.48/minute, and Frontdesk draws 25 credits at $0.01 each per extra voice minute after its included allowance; 1,000 monthly shared overage credits may cover some of that usage first. Phonely's Starter page conflicts on plan details, so confirm its rate at checkout. AIRA and Upfirst charge per extra call, with rates depending on tier. Track the first few billing cycles and compare whether upgrading is cheaper than repeated overages.
What are the limitations of Trillet's pricing?
Trillet's $49/month plan includes 150 minutes, which is a real cap, not unlimited. A business consistently running well past 150 minutes will pay $0.20/minute on top, and at very high volume that overage adds up: 500 monthly minutes works out to $49 plus 350 overage minutes at $0.20, or $119/month. That is still below most human and hybrid alternatives, but if your volume is both high and unpredictable, it is worth modeling your overage before committing. Trillet is also AI-only, so it does not offer the human-agent handoff that a hybrid service like Smith.ai does. And it's a single plan for one business's own inbound calls: one Trillet-branded agent, no outbound campaigns, and calendars as the native integrations. It isn't a reseller or multi-client product.
How much does an AI receptionist cost?
An AI receptionist can cost nothing on a limited free tier or $25–$150/month on many published self-serve plans, before extra usage. Trillet starts at $49/month for 150 inbound voice minutes, then $0.20/minute; AIRA and Upfirst start at $24.95 for 30 calls. Estimate both monthly call count and duration, then add SMS, numbers and carrier forwarding where applicable.
Is AI voice agent pricing the same as AI receptionist pricing?
Not always. An AI receptionist is an inbound, phone-focused voice AI agent; a broader voice agent may also run outbound or internal workflows with different costs and compliance requirements. For a small-business receptionist, compare the answering plan's included calls or minutes, booking capability and extra usage. Trillet's direct inbound plan is $49/month for 150 minutes with $0.20/minute overage as of September 2026.
Conclusion
AI phone answering costs run from limited free tiers to hundreds per month as of September 2026, but the real bill depends on the billing unit, included usage and extra charges. AIRA and Upfirst start paid plans at $24.95; Smith.ai starts AI Pro at $150 but also has a free 25-call tier. Trillet offers $49/150 minutes with $0.20/minute overage, supported booking, SMS follow-up and emailed summaries, but SMS costs extra and D2C cannot process HIPAA PHI under the public terms. Its 150-minute allowance is real, so model your expected volume and any carrier forwarding charges before committing.
Calculate your expected call volume, factor in the features you actually need, and compare total monthly cost rather than sticker price.

Updated for September 2026: corrected Smith.ai and per-call scenario arithmetic, removed Frontdesk's no-longer-listed $20 tier from live comparisons, clarified Rosie booking gates, separated voice-agent and receptionist scope, and replaced unsupported ROI and $49 D2C HIPAA claims with testable assumptions and current contract limits; added that reminder texts go from Trillet's A2P-registered number and that the $49 plan covers one business's own inbound calls, not resale.
