Short answer: a traditional answering service costs $0.80 to $1.70 per operator minute, $1 to $2.50 per call, or $50 to $300 per month on a flat plan - and most small businesses end up spending $150 to $400 a month once real call volume meets real invoices. An AI answering service typically runs a fraction of that. Here's where every one of those numbers comes from, what the quotes leave out, and how to figure out what you'll actually pay.
How much does an answering service cost?
It depends on which of three pricing models the provider uses - but here are the typical ranges you'll be quoted in 2026:
| Pricing model | Typical rate | Best for |
|---|---|---|
| Per minute (human) | $0.80 – $1.70 / operator minute | Short, simple calls |
| Per call (human) | $1.00 – $2.50 / answered call | Longer calls, stable volume |
| Flat monthly (human) | $50 – $300+ / month for a bundle of minutes | Predictable volume |
| AI answering service | $30 – $150 / month platform fee + cents per minute | High, spiky, or after-hours volume |
Those ranges are wide because the industry prices by its costs, not your outcome. An operator's paid time is expensive, so human services meter it closely. Software's marginal cost per call is close to zero, so AI voice agents price closer to a utility. The rest of this page unpacks each model so you can line quotes up side by side.
How answering services charge: per minute, per call, or flat monthly
Per-minute pricing is the classic model. The advertised rate usually covers operator talk time only - and the meter rounds up. A chatty caller, a complex question, or anything that needs repeating runs the bill. At $1.25/minute, a modest 300 calls a month averaging 4 minutes is $1,500 before a single surcharge.
Per-call pricing charges a fixed amount every time the line is answered, regardless of length. The catch is what counts as a "call": many providers bill wrong numbers, robocalls, and hang-ups at the same rate as a genuine customer. Check your call log before signing - junk traffic can be a fifth of what rings.
Flat monthly plans bundle a pool of minutes or calls into one price. The headline number matters less than the overage rate, because your busiest month is exactly when you'll blow through the bundle - and the busiest month is the one you bought the service for.
What is the average cost of an answering service?
For a typical small service business - a plumber, dental office, or property manager taking a few hundred calls a month - the average all-in spend on a human answering service lands between $150 and $400 per month. Low-volume accounts on small bundles can stay under $100; businesses with heavy after-hours traffic, bilingual needs, or dispatch requirements routinely clear $500. Medical and legal answering, which carry compliance and liability overhead, sit at the top of every range.
Treat any "average" - including ours - as a starting point. The only average that matters is your call volume multiplied by the real, fully loaded rate, which is where the next section comes in.
How much do answering services charge beyond the advertised rate?
The sticker rate is rarely the invoice total. Ask every provider about these before comparing anything:
- Setup and account fees. One-time onboarding charges of $50–$150 are common.
- Holiday and after-hours surcharges. Premium rates on nights, weekends, and holidays - precisely when you most need coverage.
- Patch-through and transfer fees. A charge for connecting a caller to you live.
- Per-call minimums and billing increments. A 30-second call billed as a full minute (or more) quietly raises the effective rate.
- The relay tax. The biggest cost never appears on the invoice at all: if the service only takes messages, your team still spends time on every callback. That labor is real money. We break the math down fully in our per-resolution cost breakdown.
How much does an AI answering service cost?
AI answering services usually charge a flat monthly platform fee plus usage in cents per minute - not dollars - because there's no operator payroll underneath. Plans commonly start around $30–$100 a month. Because capacity is compute rather than a shared operator pool, ten simultaneous calls cost no more per minute than one, and 3 AM costs the same as 3 PM. That structural difference is why AI pricing is most forgiving in exactly the scenarios that make per-minute human pricing painful: call spikes, after-hours emergencies, and growth.
The other difference isn't on the price sheet: a capable AI agent resolves calls - books the appointment, answers the question, sends the confirmation - instead of relaying a message that your staff still has to finish tomorrow. Same call, very different total cost. For a straight head-to-head on capability, see our honest AI vs. human answering service comparison.
Rule of thumb: compare services on cost per resolved call, not cost per minute. A cheap service that only takes messages is more expensive than it looks; a service that finishes the call is cheaper than it looks. You can see resolution-based pricing in practice on Verlingo's pricing page - published, no quote call required.
How to calculate what you'll actually pay
Pull last month's call log and run three numbers: total calls, average minutes per call, and how many calls ended finished - no callback owed. Multiply volume by the quoted rate, add the surcharges above, add your staff's callback time at their loaded hourly cost, and divide by resolved calls. That single figure - cost per resolution - makes a $1.25/minute human service and a $100/month AI platform directly comparable, and it's usually not close.
You don't have to take any vendor's math on faith, including ours. Put a service on your after-hours line for two weeks, count what it answered and what it resolved, and you'll have your own number built from your own calls.

Answering service cost FAQ
How much does an answering service cost per month?
Most small businesses pay between $150 and $400 per month for a traditional human answering service once usage, overages, and surcharges are included. Entry-level flat plans start around $50/month; AI answering services start around $30/month with per-minute usage billed in cents.
How much do answering services charge per minute?
Human answering services typically charge $0.80 to $1.70 per operator minute, with premium, bilingual, or medical answering running higher. AI answering services charge a fraction of that per minute because there is no operator labor behind each call.
What is the average cost of an answering service?
Around $200–$300 per month is a reasonable average for a small service business with moderate call volume on a human service. Your actual cost depends on call volume, average call length, after-hours usage, and the billing model.
How much does an AI answering service cost?
AI answering services typically charge a monthly platform fee - often $30 to $150 - plus usage measured in cents per minute. Because calls are resolved rather than relayed into messages, the effective cost per completed call is usually several times lower than a human service. See the full per-resolution breakdown.
Is an answering service cheaper than hiring a receptionist?
Almost always. A full-time receptionist costs salary plus roughly 25% or more in taxes and benefits, for one person's coverage during business hours only. Answering services cost a few hundred dollars a month; AI services cover 24/7 and unlimited simultaneous calls for less than that.
