# Answering service cost: what you'll actually pay Source: https://dialmilo.com/hub/answering-service-cost Updated: 2026-08-20 What answering services really cost: a receptionist at $3,000–4,000 a month, traditional plans from $250 plus overages, or pay-as-you-go AI at cents a minute. Answering service quotes are hard to compare because the headline rate is rarely what decides the bill. Billing increments, monthly minimums, and what counts as a billable call matter more. Work out your own call volume and average length first, then price each option against those numbers rather than against each other. Comparing answering services is unusually difficult, and not by accident. One quotes per minute, another per call, a third bundles a monthly plan with an overage rate. All three sound reasonable. Any of them could be the cheapest or the most expensive for your business, depending on details that rarely appear on the pricing page. Here is how the models actually work, and what to ask. ## How much does an answering service cost? Three honest reference points, before the detail: | Option | Typical cost | How it bills | Watch out for | | --- | --- | --- | --- | | In-house receptionist | $3,000–4,000/month loaded (typical US range: salary, taxes, benefits) | Salary, whether the phone rings or not | Covers about 40 hours a week — not evenings, weekends, holidays or sick days | | Traditional answering service | From ~$250/month (typical industry range) | Monthly plan with included minutes or calls, then per-minute or per-call overage | Minimums you pay in quiet months, one-minute rounding, after-hours surcharges | | Pay-as-you-go AI (Dial Milo) | ~6¢ per answered minute, no minimum | Per-second billing on answered call time only | You still need a handoff path for callers who need a human | A worked example, because these models only become comparable with numbers attached. Say you get 60 answered calls a month averaging 90 seconds. That is 90 minutes of talk time. - On a traditional plan at $250 a month, you pay $250 whether those calls arrive or not, plus overage if you exceed the included minutes. - On pay-as-you-go at ~6¢ a minute, the same month costs about $5.50, plus $3 if you want a dedicated number rather than forwarding your own. The gap narrows as volume rises, and at very high volumes the comparison shifts towards what you actually need answered rather than the raw minutes. But at typical small-business volumes it is not close, which is why the minimums and increments below matter more than any headline rate. ## The four answering service pricing models **Per minute.** You pay for connected talk time. Straightforward, and it rewards short efficient calls — provided the billing increment is honest (see below). **Per call.** A flat fee for each answered call regardless of length. Predictable, and good when your calls are consistently long. It gets expensive when a lot of your calls are twenty-second wrong numbers, because each one costs the same as a real enquiry. At Smith.ai's published $3.00-per-call overage rate, [per-call billing only pulls ahead](/hub/dial-milo-vs-smith-ai) once a single call runs past about 49 minutes. **Monthly plan with included volume.** A bundle — so many minutes or calls a month — with an overage rate beyond it. The overage rate is the number that matters, and it is usually the one printed smallest. **Per-minute with no minimum.** Common with AI services. Cost tracks usage exactly, so a quiet month is genuinely cheap and a busy one costs more. None is inherently better. Which is cheapest depends entirely on the shape of your call volume. ## The four things that decide your bill ### Billing increments This is the single biggest hidden multiplier. A service billing in **one-minute increments** charges a full minute for a fifteen-second call. If a third of your calls are short — wrong numbers, hang-ups, quick questions — you can pay two to three times the effective rate you thought you agreed. Ask directly: *what is the smallest unit you bill, and do you round up?* Per-second billing with no rounding is the honest end of this; one-minute rounding is not necessarily dishonest, but it must be in your comparison. ### Monthly minimums Human services staff your hours whether the phone rings or not, so a minimum is a reasonable thing for them to charge — [Ruby's](/hub/dial-milo-vs-ruby-receptionists) cheapest published plan is $250 a month for 50 minutes, a $5.00 included rate whether you use all 50 minutes or none of them. It is also the thing most likely to make a service expensive for a small business. Do the division. A minimum divided by the calls you actually receive gives you the real cost per call, and for light volume that number is often startling. ### What counts as billable Ask what you are charged for beyond conversations: - Wrong numbers and hang-ups - Spam and robocalls - Time spent on hold or transferring - Messages relayed to you by SMS or email - Setup, script changes, out-of-hours surcharges Every one of these is normal to charge for. The problem is only ever discovering it on the invoice. The most useful question you can ask any provider: “Based on 60 calls a month averaging 90 seconds, what is my actual monthly bill including every fee?” A provider who cannot answer that in one number is not one you can compare. ### Peak and after-hours loading Some services charge more for nights, weekends and holidays — which is exactly when you most want cover. If your reason for buying is after-hours, price the after-hours rate, not the daytime one. ## Working out your own numbers first You cannot compare quotes without your own volume. It takes twenty minutes to get. Most phone systems and mobile carriers export this. You want total calls, missed calls, and roughly when they arrive. If you do not have it, assume 60–120 seconds for routine enquiries. Booking calls run longer, information calls shorter. Not all of them. Wrong numbers and spam are volume you will be billed for but gain nothing from — worth knowing before you sign. Ask each provider for a single monthly figure at your volume, including minimums, increments and fees. Compare those figures, not the headline rates. ## Where AI pricing differs AI receptionists generally bill per minute with no minimum and no per-seat fee, which changes the shape of the decision rather than just the number: - **Light or unpredictable volume gets much cheaper**, because you are not paying to have someone rostered for calls that never come. - **Very high volume is less dramatic a saving**, since cost scales with usage in both models. - **Short calls stop being expensive**, provided billing is per-second. The honest limitation is the same one that applies everywhere in this market: cheap cover that gives wrong answers costs more than expensive cover that gives right ones. Price is the second question, after whether the service can actually handle your calls. ## What we charge, for reference We publish our pricing rather than quoting it, so you can use it as a comparison point. Dial Milo bills **per minute of answered call time**, prorated by the second, with **no subscription, no minimum, and no per-seat fee**. On the standard engine that works out to roughly **6¢ per minute** for a US number — a carrier component of about 2.6¢ and an AI component of about 3.5¢. Numbers are $3/month, or you can forward an existing one for nothing. Missed, blocked and spam calls are not billed at all, and new accounts start with $1 of trial credit, roughly 16 minutes of calls, so testing it costs nothing. The live figures, including per-country rates, are at [/pricing.md](/pricing.md) and [/rates.md](/rates.md) — generated from the same system that produces the invoices, so they cannot drift from what you are actually charged. Whether that is cheaper than a human service for you depends on your volume and how much of your call mix genuinely needs a person. We wrote that comparison up in [Dial Milo vs a traditional answering service](/hub/dial-milo-vs-answering-service), and the after-hours case specifically in [after-hours answering services](/hub/after-hours-answering-service). ## Frequently asked **How much does an answering service cost per month?** It depends almost entirely on the pricing model rather than the headline rate. Services bill per minute, per call, or by monthly plan, and most have a minimum you pay whether the phone rings or not. Two services quoting similar rates can differ several-fold on your actual bill, which is why you have to price them against your own call volume. **What does pay-as-you-go actually cost in a typical month?** Take your answered calls, multiply by average length, then by the per-minute rate. Sixty 90-second calls is 90 minutes, which at Dial Milo's ~6¢ per minute comes to about $5.50. There is no minimum, so a quiet month costs almost nothing and you never pay for capacity you did not use. **Is per-minute or per-call pricing better?** Per-call suits businesses with lots of short calls; per-minute suits fewer, longer ones. The trap is billing increments — a service that rounds every call up to the next minute charges you a full minute for a fifteen-second wrong number. Ask what the increment is before you compare anything. **What is a typical answering service minimum?** Most human services carry a monthly minimum because they staff your hours whether calls arrive or not. That is reasonable for them and expensive for you if your volume is light — the effective cost per answered call can be many times the headline rate. AI services generally have no minimum. **Why do answering services hide their pricing?** Because the answer is genuinely 'it depends', and because a quote lets them anchor on your call volume. It is not necessarily bad faith. But it does mean you should arrive with your own numbers rather than letting a package tier decide what you need.
