> A loaded-cost comparison of LLM receptionists vs human staff, using BLS wage data and published AI pricing, plus the real benefits and limits on each side.

A cost-benefit analysis weighs what you spend against what you actually get back, and for front-desk staffing that means comparing the full loaded cost of a human receptionist against an LLM-based receptionist's subscription cost, then weighing each option's real strengths and limits, not just the sticker price. A full-time receptionist's total cost typically runs meaningfully above their base salary once payroll taxes and benefits are added, while an LLM receptionist's cost scales with call volume on a monthly plan. The right choice depends on your call volume, hours of coverage needed, and how much of your call mix is routine versus emotionally complex.

This guide is for a small business owner or practice manager deciding how to staff phone coverage, not a technical evaluation of the AI itself. It walks through the true cost of a human receptionist using government wage data, the cost structure of an LLM receptionist, a side-by-side at different call volumes, and the benefits each option delivers that a price tag alone won't show you.

> **Key Takeaways**
>
> - The median receptionist earns $38,010 a year ($18.27/hour); nationally, there are about 947,500 receptionist jobs, and BLS projects a 2% employment decline through 2035 even as roughly 105,100 openings occur annually from turnover (SOURCED, [BLS Occupational Outlook Handbook, Receptionists](https://www.bls.gov/ooh/office-and-administrative-support/receptionists.htm), retrieved 2026-09-25).
> - Salary is not the full cost. Across private industry, benefits make up about 30% of total compensation (roughly 43% on top of wages), bringing average total compensation to roughly $46.89 per hour against $32.82 in wages alone (SOURCED, [BLS, Employer Costs for Employee Compensation](https://www.bls.gov/news.release/ecec.nr0.htm), retrieved 2026-09-25). Applying that ratio to the receptionist wage puts a fully loaded annual cost near $54,300 (ANALYSIS).
> - An LLM receptionist like Voksha starts at $14/month for 15 calls (then $1/call), $99/month for 150 calls (then $1/call), or from $990/month on Enterprise; cost scales with call volume, not headcount.
> - A human receptionist covers roughly 40 hours a week; an LLM receptionist answers around the clock, so the comparison isn't purely dollar for dollar unless you also value the added hours.
> - Cost-benefit isn't only about price: humans bring judgment and emotional nuance an AI cannot fully replicate, and an AI brings consistency and availability a single employee cannot.
> - Most businesses land on a hybrid: automate the routine, high-volume calls and keep a human for complex or high-stakes conversations.

## What "Cost-Benefit Analysis" Means Here

A cost-benefit analysis is a simple discipline: list what each option costs, list what each option delivers, and compare the two honestly, including the parts that don't fit neatly into a dollar figure. For front-desk staffing, the cost side is the easier part to calculate: a salary and benefits package versus a software subscription. The benefit side is harder because it includes things like after-hours availability, consistency call after call, and the ability to hold an emotionally difficult conversation. This guide treats both sides seriously instead of stopping at "which is cheaper," because cheaper isn't the same as better for every business.

## The Full Cost of a Human Receptionist

The salary listed in a job posting understates what a receptionist actually costs a business. Nationally, the median receptionist earns $38,010 a year, or $18.27 an hour, across about 947,500 jobs in the role ([BLS Occupational Outlook Handbook, Receptionists](https://www.bls.gov/ooh/office-and-administrative-support/receptionists.htm), retrieved 2026-09-25). That's before payroll taxes, health insurance, paid time off, and other benefits are added on top.

Across private industry generally, benefits make up about 30% of total compensation: average wages run $32.82 an hour against $14.07 in benefit costs, for total compensation of $46.89 an hour ([BLS, Employer Costs for Employee Compensation](https://www.bls.gov/news.release/ecec.nr0.htm), retrieved 2026-09-25). Applying that same ratio to the receptionist wage ($38,010 ÷ 0.70) (an estimate, not a BLS-published figure specific to this role) puts a fully loaded annual cost for one full-time receptionist near $54,300 (ANALYSIS). That figure still doesn't include recruiting time, onboarding, training, or the cost of a gap in coverage when that employee is out sick, on vacation, or between jobs. BLS also notes that turnover alone drives roughly 105,100 openings for this role every year, which gives a sense of how often that hiring cost repeats ([BLS Occupational Outlook Handbook](https://www.bls.gov/ooh/office-and-administrative-support/receptionists.htm), retrieved 2026-09-25).

## The Cost Side of an LLM Receptionist

An LLM-based receptionist like [Voksha](https://voksha.com/pricing/) is priced on a subscription that scales with call volume rather than headcount. Starter runs $14 a month for 15 calls, then $1 per additional call. Premium runs $99 a month for 150 calls, then $1 per additional call. Enterprise, aimed at multi-location or heavily regulated practices, starts from $990 a month. There's no salary, no benefits, and no recruiting cycle; the tradeoff is that the cost is directly tied to how many calls come in, which is worth mapping against your actual call volume before comparing numbers.

## Side by Side: Cost at Different Call Volumes

The comparison below uses Voksha's published plan pricing against the fully loaded human receptionist estimate above. It assumes a single full-time receptionist handling all calls, which is the realistic minimum for full coverage; a business needing after-hours or multi-line coverage would need to add a second shift or overtime to the human side, which isn't reflected here.

| Monthly call volume | Voksha cost (ANALYSIS) | Human receptionist cost (loaded, per month) |
|---|---|---|
| 15 calls | $14 (Starter, included) | ~$4,525 |
| 100 calls | $99 (Premium, included in 150-call tier) | ~$4,525 |
| 300 calls | $99 + 150 calls over Premium's 150-call limit at $1/call = $249 | ~$4,525 |
| 1,000+ calls, multi-location | From $990 (Enterprise) | Cost scales with additional hires |

The loaded human cost stays roughly flat regardless of call volume until you exceed one person's capacity, at which point you need a second hire, whereas the AI cost scales up gradually with volume. At low-to-moderate call volume, the dollar gap favors the AI option by a wide margin. At very high call volume requiring multiple simultaneous conversations, an Enterprise plan should be evaluated directly against the cost of the additional human hires it would otherwise take.

## The Benefit Side: What Each Option Actually Delivers

| Factor | LLM receptionist | Human receptionist |
|---|---|---|
| Availability | Answers 24/7, including nights, weekends and holidays | Limited to scheduled hours, typically a single shift |
| Consistency | Same tone and process on every call | Can vary with mood, fatigue or training gaps |
| Simultaneous calls | Can handle overlapping calls without a busy signal | One call at a time |
| Emotional nuance | Limited; not built for distressed or highly sensitive conversations | Strong; can read tone, adapt, and reassure in real time |
| Complex judgment calls | Follows defined rules and escalates what it can't handle | Can use independent judgment on unusual situations |
| Setup time | Under 5 minutes, by forwarding your existing number | Weeks, for hiring, background checks and training |
| Ongoing management | Minimal; adjust the plan or configuration as needed | Requires supervision, scheduling and periodic retraining |

Neither column "wins" outright. A landscaping company fielding routine scheduling calls gets most of the AI's benefit and little of the human's advantage. A grief counseling practice or a firm handling sensitive legal intake leans the other way for at least some of its calls.

## Where the Math Doesn't Favor Automation

Being honest about limits is part of a real cost-benefit analysis. An AI receptionist is the wrong tool, or at least an incomplete one, for calls that involve genuine emotional distress, complex negotiation, or a caller who needs a person to exercise judgment outside a predefined script. A business with extremely low call volume, say a handful of calls a month, may find that a part-time or shared human answering the phone is simple enough that the calculation barely matters either way. And a practice with heavy compliance requirements around every patient or client interaction should weigh that against automation carefully, even where the dollar savings look attractive on paper.

## Building Your Own Cost-Benefit Case

1. Pull your last three months of call logs and count total calls, average call length, and how many happened outside business hours.
2. Calculate your current loaded cost per receptionist using your actual salary and benefits, not the BLS averages used here.
3. Map your call volume against the plan tiers above to estimate an AI receptionist's actual monthly cost for your business.
4. Separate your calls mentally into "routine" (scheduling, hours, basic questions) and "complex" (emotionally sensitive, high-stakes, or requiring judgment), and weight the benefit side accordingly.
5. Decide whether a hybrid model, AI for routine and after-hours calls, a human for the rest, changes your total cost more than a pure either-or choice would.

## Frequently Asked Questions

### What does a human receptionist actually cost, beyond salary?

The median salary is $38,010 a year, but total employer cost is higher once benefits are added; across private industry, benefits typically make up about 30% of total compensation ([BLS](https://www.bls.gov/news.release/ecec.nr0.htm), retrieved 2026-09-25). Applying that ratio puts a fully loaded cost near $54,300 a year for one full-time receptionist (ANALYSIS), before recruiting or training costs.

### How is an LLM receptionist priced compared to a salary?

It scales with call volume on a monthly subscription rather than a fixed salary. Voksha starts at $14/month for 15 calls, $99/month for 150 calls, or from $990/month on Enterprise; Starter and Premium each charge $1 per call beyond the included volume.

### Is an AI receptionist always cheaper than a human one?

At low and moderate call volumes, the dollar cost strongly favors the AI option. At very high call volume needing multiple simultaneous conversations, compare an Enterprise plan directly against the cost of the additional human hires it would replace, since the math narrows.

### Can an AI receptionist fully replace a human for every kind of call?

No. It's well suited to routine scheduling, FAQs, and after-hours coverage, but it isn't built for calls requiring deep emotional nuance or independent judgment in unusual situations. Most businesses get the best result from a hybrid setup rather than an all-or-nothing choice.

## Conclusion

A real cost-benefit analysis puts a full, loaded number on the human side, not just a salary, and weighs the AI side's availability and consistency against its real limits with complex or emotional calls. For most small businesses, the math favors using an LLM receptionist for routine, high-volume and after-hours calls, and keeping a human for the calls that need judgment.
