AI receptionist vs human: the real cost maths

A full-time human receptionist costs about $3,410 a month in the US on statutory numbers alone (median wage plus employer payroll tax), and about £2,349 in the UK. The AI receptionist products we track run $20 to $799 a month. AI is genuinely far cheaper; the vendor blogs still overstate the gap.

That is the piece in one paragraph; the rest is the workings, because the workings are where the vendor blogs go wrong. They pad the human baseline until the saving hits a marketing-friendly number, then compare a full-time employee against their own cheapest plan. The honest gap does not need padding.

Where the “93-95% cheaper” claim comes from

Search for AI receptionist pricing and the results are vendor blogs marking their own homework. Three current examples, each quoted as a claim, not adopted (links and capture dates in the sources below):

• NextPhone’s cost guide (updated 2 June 2026) prices a human receptionist at “$52,925 to $77,190” a year, then concludes AI “saves 93-95%”. The baseline starts from a BLS salary and keeps stacking: a 25 to 35 per cent benefits multiplier, payroll taxes, recruitment and training, turnover write-offs, even the desk and computer.
• Aira’s comparison (updated 23 April 2026) claims “a 98.6% savings” by setting a $60 a month AI plan against a $52,900 a year human. Its wage sourcing is more careful than most, but the comparison is a full-time salaried employee against the smallest plan on the price list, with no equivalence of hours or call volume.
• Cira’s pricing guide (17 March 2026) says an AI receptionist is “93% to 95% cheaper”, putting a human at “$44,000 to $60,000 a year” once benefits and payroll taxes are added to salary. No source is given for any of the human-cost figures.

Two problems, and neither is the arithmetic. First, the baseline. Recruitment, training time, turnover and the desk are real costs of running a front desk, but you do not escape them by buying software: someone still has to set the AI up and check its call logs. The honest floor is the statutory cost, meaning the wage plus the payments the law obliges an employer to make, nothing else. Second, the scope. A receptionist answers the phone and also greets walk-ins, signs for deliveries, chases the diary and knows when a rule should bend. The $60 plan does one of those things. Comparing the two as straight substitutes is how you get a 98.6% headline.

What a human receptionist actually costs, statutory only

The US numbers

The BLS Occupational Employment and Wage Statistics series (the US government’s wage census; occupation 43-4171, Receptionists and Information Clerks) puts the May 2025 median at $18.27 an hour, or $38,010 a year, across 910,180 jobs. On top of the wage, federal law obliges the employer to pay FICA (the US payroll tax that funds Social Security and Medicare) at 6.2% plus 1.45%, so 7.65% of the wage. Receptionist pay sits so far below the $184,500 Social Security cap that the full rate always applies.

We left out federal and state unemployment insurance and workers’ compensation on purpose: they vary by state, and we will not guess. So $3,410 a month is a deliberately conservative floor.

If you want the with-benefits picture, the honest route is BLS’s own employer-cost survey (ECEC, March 2026 release): across private industry, wages are $32.60 of a $46.60 total hourly cost, so benefits make up 30.1 per cent of the total. Apply that ratio to the receptionist median and you get 38,010 ÷ 0.699, roughly $54,400 a year, call it $4,530 a month. Two labels belong on that number. It is an all-occupations average applied to one occupation’s median, an illustration, not a measurement. And do not add the 7.65% FICA on top: the ECEC benefits bucket already counts the legally required contributions, so the blogs stacking a benefits multiplier and then payroll taxes are double-counting.

The UK numbers

The UK equivalent comes from the ONS Annual Survey of Hours and Earnings (ASHE 2025 provisional, released 23 October 2025). For SOC code 4216, Receptionists, the full-time median is £24,678 a year, or £13.22 an hour. We quote the GBP figures as the ONS publishes them; every other price on this site is USD, and we do not convert.

Two statutory payments sit on top for 2026-27. Employer National Insurance (the UK employer payroll tax) runs at 15% of pay above £5,000 a year. And auto-enrolment (the workplace pension the law makes an employer provide) requires an employer contribution of at least 3% of qualifying earnings, the band from £6,240 to £50,270.

Now the wrinkle no vendor blog mentions: the Employment Allowance. Eligible employers (broadly, the smaller ones) take up to £10,500 a year off their employer NI bill. A receptionist’s entire £2,951.70 NI line fits inside that allowance, so for exactly the small firms AI receptionists are sold to, the statutory cost can drop to 24,678 + 553.14, which is £25,231.14 a year, about £2,103 a month. The strawman gets cheaper the closer you look.

One more dose of reality: most UK receptionist jobs are not full-time. The same ASHE table counts roughly 105,000 part-time receptionist jobs against 80,000 full-time. A 20-hour week at the all-employees median of £12.95 an hour is 12.95 × 20 × 52, about £13,468 a year, or £1,122 a month before employer NI (which the Employment Allowance can take to zero). That, not $52,900, is the human cost many small firms are weighing. It has little room to fall further, mind: the National Living Wage floor is £12.71 an hour from April 2026, and the receptionist medians sit barely above it.

What an AI receptionist actually costs

Now the other side of the ledger, from our dated captures. It comes in two shapes: subscription products sold as ready-made receptionists, and per-minute platforms you configure yourself (our cost-per-minute breakdown covers how those bills stack). The subscriptions first; Frontdesk was captured 11 July 2026, ServiceAgent and Ringly on 15 June 2026.

Read the small print with the sticker. Frontdesk’s $20 plan includes no voice minutes at all; it exists so you can try the dashboard. The $99 plan carries 200 minutes and then meters at $0.25 a minute (overage just means the metered rate once your included minutes run out). ServiceAgent counts in credits, 15 per voice minute, which works out at roughly $0.30 to $0.60 a minute. So a receptionist product’s real monthly bill is the plan price only while your call volume stays inside the allowance.

The per-minute platforms are the other route: more setup, and the bill scales with usage. Rather than recompute anything by hand, here are the reference estimates our calculator renders from each vendor’s dated rates (built 12 July 2026), at two monthly volumes:

*The Vapi estimate excludes the language model, which you bring and pay for separately.

A footnote on the budget end: Synthflow, long the cheap no-code option in this category, pulled its self-serve pricing between our 15 June and 11 July captures. Its pricing page is now a single enterprise card reading “contracts start at $30,000 annually”.

The honest gap

So is an AI receptionist cheaper? Enormously, for the slice of the job it does. Set the mid-market subscriptions ($99 to $349 a month) against the US statutory full-timer at $3,410 a month and the gap runs roughly 10 to 34 times (3,410 ÷ 349 and 3,410 ÷ 99). You do not need a padded baseline to make this case, which is what makes the padding so needless.

But the percentage framing hides the decision that matters, because a saving is only a saving if you were going to buy the thing. If your real problem is missed calls, the alternative to a $99 AI plan was never a $40,918 full-time hire; it was a part-time hire (about £1,122 a month in the UK workings above), or voicemail quietly losing bookings. And if your real problem is the front desk itself (walk-ins, deliveries, the post, judgement on when a rule should bend), an AI receptionist does not cover it at any price. We looked for a credible “X% of callers refuse to talk to bots” statistic and could not trace one to a primary study, so we will say it editorially: some of your callers will always want a person, and you know your callers better than we do.

Our position: price the AI against the calls it will actually take, not against a salary you were never going to pay. On that comparison it wins easily, and honestly.

The hybrid most small firms should actually run

The either/or frame is the strawman’s last trick. The configuration we would run for most small firms is a human on the desk in opening hours and the AI on everything else: evenings, weekends, bank holidays, and the overflow when the line is already busy. After-hours volume for a small firm usually sits nearer the 500-minute column than the 2,000-minute one, so the AI half of a hybrid runs about $25 to $300 a month on the platforms above, while the human keeps the walk-ins and the judgement calls. Missed calls stop being the silent cost. Our AI receptionist use-case page covers which platforms fit this pattern.

Before you buy: the 2 August disclosure duty

One compliance date belongs in any receptionist budget. From 2 August 2026, Article 50 of the EU AI Act requires that people interacting with an AI system are told so, “at the latest at the time of the first interaction”, and the fines for the transparency duties reach €15 million or 3% of worldwide turnover (Article 99(4)). If your AI receptionist takes calls from people in the EU, the disclosure line goes in the greeting from day one; it costs one sentence of prompt. The full breakdown, including the US robocall rules, is in our disclosure-duty piece.

Next step: put your own monthly call minutes into the calculator and set the result against the statutory tables above. The maths is the easy part. Deciding which parts of the receptionist’s job you actually need covered is the real work.
