Answering service per minute pricing looks cheap at the bottom and gets expensive fast. A low monthly base buys a small bundle of talk minutes, then every extra minute bills at $2.95 to $4.70. Worked at 100, 300, 800 and 1,500 minutes, the published plans tell a very clear story about where the model breaks.
How does answering service per minute pricing work?
Three things set your bill: the base plan, the bundled minutes and the overage rate. OnceHub’s September 2026 roundup puts human answering plans at roughly $235 a month for 50 minutes up to $1,095 for 500 minutes, with overage between $2.95 and $4.70 a minute, and AI receptionists at $25 to $300 a month flat.
The trap is not the base price. It is that almost nobody estimates their talk time correctly. Owners think in calls; plans bill in minutes; and a three-minute booking call with hold time and a transfer can bill at four or five. Buy the tier that matches last quarter’s actual minutes, not the tier that matches the number you hope for.

Two other published reference points from the same market: Moneypenny sells dedicated receptionist teams with around $1,000 of onboarding, and Abby Connect plans run up to about $1,380 a month. Figures as published in September 2026; check the current pages before you budget.
What do the plans cost at 100, 300, 800 and 1,500 minutes?
The table below works each published structure at four volumes. Smith.ai bills per call, so its rows assume an average call length of three minutes, which is an illustrative assumption you should replace with your own average. All other figures come straight from the published base plus published overage.
| Monthly talk time | Ruby | Smith.ai (3-minute calls) | AnswerConnect | In-house receptionist benchmark |
|---|---|---|---|---|
| 100 minutes | About $470 | About $321 (33 calls) | $325 | About $3,170 |
| 300 minutes | About $1,095 on the 500-minute tier | About $975 (100 calls) | About $915 | About $3,170 |
| 800 minutes | About $2,505 | About $2,603 (267 calls) | About $2,390 | About $3,170 |
| 1,500 minutes | About $5,795 | About $4,875 (500 calls) | About $4,455 | About $3,170 |
Now the same numbers as effective cost per minute, which is the only comparison that means anything.
| Monthly talk time | Ruby | Smith.ai | AnswerConnect | In-house benchmark |
|---|---|---|---|---|
| 100 minutes | $4.70 | $3.21 | $3.25 | $31.70 |
| 300 minutes | $3.65 | $3.25 | $3.05 | $10.57 |
| 800 minutes | $3.13 | $3.25 | $2.99 | $3.96 |
| 1,500 minutes | $3.86 | $3.25 | $2.97 | $2.11 |
Read the last two rows carefully. At 100 minutes the flat-rate person costs ten times more per minute and nobody should buy one. At 1,500 minutes the flat-rate person costs roughly half what the cheapest per-minute plan costs, and the shared desk has become the expensive option. Nothing changed except volume.
Where does per minute stop making sense?
Solve for the point where the per-minute bill equals the flat-rate benchmark of about $3,170 a month.
| Provider | Break-even talk time | In calls, at 3 minutes each |
|---|---|---|
| Ruby at $4.70 over the 500-minute tier | About 940 minutes | About 313 calls |
| Smith.ai at $9.75 a call over 30 calls | About 325 calls | About 975 minutes |
| AnswerConnect at $2.95 over 100 minutes | About 1,065 minutes | About 355 calls |
So the crossover clusters between roughly 900 and 1,100 talk minutes a month, or 15 to 18 hours. Below that, per minute wins on price. Above it, a dedicated person wins and keeps winning, because the flat line does not move while the per-minute line keeps climbing.
Two adjustments will shift your own crossover. The BLS figure is wage only, so payroll tax, benefits, equipment and software seats push the true in-house cost higher, moving the crossover up. On the other side, a dedicated receptionist is paid for availability rather than talk time, so the same person can do intake, scheduling, follow-up and admin between calls. Once you count that recovered work, the crossover usually arrives earlier than the pure minute math suggests.
There is a third effect nobody budgets for: minute inflation. Billed minutes are not conversation minutes. Greetings, hold time while the receptionist looks something up, transfer time and the wrap-up all sit inside the billed total, and rounding pushes it further. A practice that believes it talks for two minutes per call and actually bills three has understated its plan by 50 percent before a single overage minute is counted.
Tier choice compounds it. Take a business at 300 minutes on a provider with a $235 base for 50 minutes and $4.70 overage. Staying on the entry plan costs about $1,410. Moving to the published 500-minute plan at $1,095 saves $315 a month for the same usage, and that is with 200 minutes going unused. Most buyers never rerun this, so they pay overage on a plan they outgrew two quarters ago. Put a quarterly reminder in the calendar and check the tier against last quarter’s actual minutes.
What should you check before you sign?
Ask these in writing. Most of them are not on the pricing page, and each one can change your bill by 20 percent or more.
- What is the billing increment? Per second, per 30 seconds or per minute rounded up. Rounding up a 90-second call to two minutes adds up across 300 calls.
- Does hold time bill? Including the time a caller waits while the receptionist looks something up.
- Does transfer time bill? Including the seconds after the caller is connected to you.
- Are spam, wrong-number and robocalls billed? Ask what proof you get, and whether there is a credit process.
- Do outbound calls and texts draw on the same bundle? Reminder calls can consume a plan quickly.
- Do unused minutes roll over? If not, buying the next tier up is pure waste in quiet months.
- What is the overage rate and when does it apply? Confirm the exact number, not the range.
- Can you upgrade mid-month? Providers differ, and one bad month on the wrong tier is expensive.
- Is there onboarding or setup cost? Dedicated teams sometimes carry a one-time fee, around $1,000 in Moneypenny’s published model.
- What is the notice period? Month to month versus annual changes the risk of getting the tier wrong.
Which model fits which business?
| Your situation | Best-fit model | Why |
|---|---|---|
| Under 300 talk minutes a month | Per minute or per call | The base plan covers you and overage stays small |
| 300 to 900 minutes, spiky | Per minute on the right tier, reviewed quarterly | Cheaper than a person, as long as you resize the plan |
| Over 900 minutes, steady | Dedicated receptionist at a flat rate | The per-minute line has crossed the flat line |
| Any volume, plus admin between calls | Dedicated receptionist who also does the desk work | You are paying for availability, so use all of it |
| Overflow and after hours only | AI triage plus human escalation | $25 to $300 flat covers the low-value calls |
| Detailed intake, long calls | Flat rate or per call, never per minute | Long calls are where per-minute bills run away |
A practical routine: export your phone report every quarter, total actual talk minutes, divide your bill by that number and write the result on a sticky note. The moment your effective cost per minute stops falling as volume rises, you are on the wrong model.

The short version on answering service per minute pricing: it is genuinely the cheapest way to cover a quiet phone, and one of the most expensive ways to cover a busy one. Run your own minutes through the published rates above every quarter, and switch models the moment the lines cross.
Frequently asked questions
How does answering service per minute pricing work?
You buy a monthly bundle of talk minutes at a fixed base price, then pay an overage rate for every minute beyond it. OnceHub's September 2026 roundup puts human plans at roughly $235 a month for 50 minutes up to $1,095 for 500 minutes, with overage of $2.95 to $4.70 a minute. The base looks small and the overage does the damage, because most buyers underestimate their talk time in the first three months.
Is per-call pricing better than per-minute pricing?
It depends on how long your calls run. Smith.ai's live plans start at about $292 for 30 calls with $9.75 a call over, which is predictable if your calls are long and expensive if they are short. Per-minute pricing rewards short calls and punishes detailed intake. Pull your phone report, find your average call length, then convert both models to cost per minute so you are comparing the same thing.
At what volume should I stop using a per-minute plan?
Around 900 to 1,100 talk minutes a month, which is roughly 15 to 18 hours or about 300 to 350 calls at three minutes each. Above that, the published overage rates push a per-minute bill past the cost of a flat-rate person. The BLS Occupational Outlook Handbook gives a median US receptionist wage of $38,010 a year before benefits, based on May 2025 data, which is about $3,170 a month.
What hidden charges should I ask about?
Five things. The billing increment, since per-second and per-minute rounding change the bill materially. Whether hold time, transfer time and the greeting count as billed minutes. Whether spam and wrong-number calls are billed. Whether outbound calls and texts draw on the same bundle. And what happens to unused minutes at month end. Ask for these in writing before you sign, because they are rarely on the pricing page.
Does an AI receptionist solve the cost problem?
It solves the price problem and creates a different one. OnceHub's September 2026 roundup puts AI receptionists at $25 to $300 a month flat, which is far below any human plan at volume. The tradeoff is handling anything the script did not anticipate: an upset caller, a complicated intake, a judgment call about a booking. Many practices run AI for overflow and after-hours triage and keep people on new-business calls.
