Almost nobody in this category sells hours, so the honest answer is that the hourly price is something you compute, not something you read. The three billing shapes you will meet are per-session plans, prepaid credit-hour packs and per-minute credits, and each converts into a different real cost per hour of interviewer speech. Hold one scenario fixed, eight forty-five-minute interviews in a month, and the same category of product lands anywhere between roughly nine and thirty-six dollars for every hour the interviewer is actually talking. The table below does that conversion.
The scenario every row below uses
A single scenario, held constant, is the only way these models become comparable. Here it is, with the assumptions stated openly so you can replace them.
- Eight interviews in one month. A moderately active search: a few recruiter screens, a few technical rounds, one small onsite loop.
- Forty-five minutes booked per interview. That is 360 minutes, or 6.0 hours, of wall-clock session time.
- Fifteen minutes of interviewer speech per interview. That is 120 minutes, or 2.0 hours. This is an assumption I am choosing, not a measured figure. In a rapid-fire screen it will be higher. In a round where you talk through a design for half an hour it will be much lower.
So the wall clock runs three times longer than the interviewer speaks. That ratio is the whole story, because it is the multiplier any wall-clock meter quietly applies to its advertised rate.
The normalisation table
Prices in the first four rows are illustrative placeholders chosen to show the arithmetic, not quotes from any named vendor. Substitute whatever a vendor's page shows you and the method still holds. The final row uses published OfferPilot AI pricing.
| Metering model | Example sticker price | What the clock counts | Units billed in the scenario | Month total | Per hour of interviewer speech |
|---|---|---|---|---|---|
| Per session, pay as you go | $9.00 per session, any length | Nothing. One charge per session started | 8 sessions | $72.00 | $36.00 |
| Flat monthly, sessions uncapped | $60.00 per month | Nothing. Time is not metered at all | 1 month | $60.00 | $30.00 |
| Credit-hour pack | $40.00 for 10 hours, so $4.00 per hour | Wall-clock session time, silence included | 6.0 wall-clock hours | $24.00 | $12.00 |
| Per-minute credits | 500 credits for $25.00, 1 credit per minute, so $3.00 per hour | Wall-clock session time, per minute | 360 minutes | $18.00 | $9.00 |
| Flat monthly, listening time metered | $39.00 per month, 3 hours per day (OfferPilot Pro) | Only while interviewer audio is arriving | 120 speech minutes across 8 days | $39.00 | $19.50 |
Two things fall out of that. First, the two wall-clock rows carry a hidden 3x multiplier: a pack that reads $4.00 an hour costs $12.00 per hour of speech, and $3.00 an hour becomes $9.00. The sticker rate and the useful rate are different numbers, and only one of them gets printed. Second, at this volume the consumption plans genuinely win. Eight interviews is not enough usage to amortise a subscription, and any page telling you otherwise is selling something.
What changes when you interview more
Consumption pricing holds its rate flat forever. Subscriptions divide down. The crossover is the number that actually decides your purchase, and it sits at a specific volume.
| Interviews that month | 4 | 8 | 16 | 32 |
|---|---|---|---|---|
| Interviewer speech, hours | 1.0 | 2.0 | 4.0 | 8.0 |
| Wall-clock session, hours | 3.0 | 6.0 | 12.0 | 24.0 |
| Per session at $9.00 | $36.00 | $36.00 | $36.00 | $36.00 |
| Credit hours at $4.00 per wall-clock hour | $12.00 | $12.00 | $12.00 | $12.00 |
| Per-minute credits at $0.05 | $9.00 | $9.00 | $9.00 | $9.00 |
| Flat $60.00 per month | $60.00 | $30.00 | $15.00 | $7.50 |
| Flat $39.00 per month, speech metered | $39.00 | $19.50 | $9.75 | $4.88 |
The $39.00 subscription passes under the $9.00 per-minute plan at about 4.3 hours of interviewer speech, which is roughly eighteen interviews in a month. Below that, buy minutes. Above it, buy a month. And if your search is one screen plus one final round, the relevant figure is not the hourly rate at all, it is the minimum purchase, where a free tier is the correct answer.
Daily caps behave differently from monthly pools, and people misread them constantly. A three hour daily cap is not ninety hours a month and was never meant to be. It binds only on the day you exceed it. Five onsite rounds in one day, at fifteen speech minutes each, is seventy-five metered minutes, comfortably inside a three hour ceiling. The cap bites if you run a full day of back-to-back mock sessions, not if you are interviewing.
One more piece of arithmetic worth doing yourself. A $249 one-time pass covering six months at a six hour daily cap works out at $41.50 a month. Against a $69 monthly plan with the same daily cap over the same six months, $414, the pass is $165 cheaper. Against a $39 monthly plan it costs $15 more in total and doubles the daily ceiling. Whether that trade is good depends entirely on whether your search really runs six months, which most people overestimate. Check the current numbers on the pricing page rather than trusting a figure quoted inside a guide.
How to get a real number out of any vendor in ten minutes
None of this can be done from a pricing page. Four steps, on a free tier or a trial, and none of them require you to spend anything first.
Write down your own scenario first
Interviews per month, minutes booked per interview, and an honest estimate of how long the interviewer talks. Do this before you look at any plan, so the vendor's example volume does not anchor you. With no idea on the speech figure, start at one third of the slot and correct it after your next call.
Run the silent-session test
Start a session, play no audio and say nothing, leave it open for ten minutes, stop it, then check the remaining balance. Ten minutes gone means the meter counts wall-clock time and your effective rate carries the full 3x multiplier. Close to nothing gone means it counts audio, and the sticker rate is near the truth.
Find the reset and the expiry
Daily allowance, monthly pool, or a pack that persists until spent? Does an unused balance roll over, and do credits expire? A pack that expires after thirty days is a monthly subscription with extra steps and should be divided as one.
Divide, then re-run at half and double
Total monthly spend over your speech hours gives the real rate. Then recompute at half your volume and at twice your volume. Searches are bursty, and the plan that wins in a quiet month often loses badly in the month your onsite loop lands.
Where speech-time metering stops helping you
Metering listening time only, which is what OfferPilot AI does, removes the 3x multiplier. It does not create value out of nothing, and there are several cases where it buys you almost nothing.
- The advantage shrinks when the interviewer talks constantly. A rapid-fire behavioural round with questions arriving back to back has a speech ratio close to the wall clock, so speech metering and session metering converge. The saving is large in a design round full of long silences and near zero in a fast screen.
- Windows 10 and 11 only. No macOS, no Linux, no mobile, no browser extension. On a Mac the cost per hour is not a decision you get to make, and no comparison table changes that.
- A five minute daily free tier tests the plumbing, not a full interview. It confirms the audio loopback works with your headset and that the overlay behaves on your machine. It is not enough to rehearse a round, and treating it as a full trial wastes your time.
- Capture exclusion is narrower than it sounds. The overlay is excluded from screen capture at the operating system level, so it stays out of Zoom, Teams, Meet, OBS and screenshots while remaining visible on your own monitor. It does nothing about webcam monitoring, a lockdown browser, eye tracking, a second-device camera, or a proctor sitting in the room. If your assessment is supervised that way, treat the tool as unavailable and prepare instead.
There is also a case where the cheapest plan is the wrong purchase entirely. If you have three interviews lined up for one role, the hourly rate is noise. Build a company-specific question bank and rehearse against it, which costs nothing per hour, and look at how live assistance actually works only once you know whether you want it in the room at all.
Any per-hour figure is a fraction. Vendors compete loudly on the numerator and stay quiet about the denominator, which is where the entire difference lives.
The short version
Divide your realistic monthly spend by the hours the interviewer actually speaks, never by the hours you have a session open. Assume a 3x gap between those two unless a silent-session test proves otherwise. Below roughly fifteen interviews a month, per-minute credits usually give the lowest real rate. Above that, a flat monthly plan pulls ahead and keeps pulling. Check what the clock counts before you check the price, because that one fact moves the number further than any tier upgrade or discount code will. If you want to see the same arithmetic applied across the tools people weigh against each other, the category comparison is the next thing to read.
