How much does usability testing cost?

In short: the price of a usability test is mostly people and time: paying participants, finding them, running the sessions and watching the recordings. Testing one flow with five people costs roughly $800 to $4,000 per round once staff time is counted, less with colleagues and more with an agency. The formula below lets you estimate your own number.

What goes into the price

Every usability test, however it is run, has the same four costs:

• Participants. The incentive you pay each person for their time.
• Recruiting. Finding people who match your audience, screening them and replacing the ones who do not show up.
• Running the sessions. Writing the task, then moderating each session live or setting up an unmoderated study.
• Analysis. Watching the recordings, noting where people got stuck and turning that into fixes.

Tools for recording and storing sessions are usually the smallest line. The approaches below differ mainly in which of these costs they take off your hands.

A formula you can reuse

cost of one round = participants × (incentive + recruiting cost)
                  + staff hours × hourly rate
                  + tools

Plan around five participants per round. Jakob Nielsen’s research found that five users uncover about 85% of the usability problems in a design, and that three rounds of five, with fixes in between, find more than one study of fifteen.

Worked example: one flow, five people

Nielsen Norman Group’s cost breakdown for remote studies gives the cash and staff hours for a five-person study. The table adds staff time at an assumed $50 an hour; replace it with your own rate.

Approach	Cash for five people	Staff hours	Staff time at $50 an hour	Total per round
Do it yourself, moderated	$415 to $1,680	32 to 48	$1,600 to $2,400	$2,015 to $4,080
Do it yourself, unmoderated	$250 to $1,250	11 to 27	$550 to $1,350	$800 to $2,600
Hallway Test	$145 (five tests at $29)	Minutes to describe each flow	Your review of the fixes	About $145, plus review time

Two things stand out. Staff time costs more than the participants in both do-it-yourself rows, so the cheapest-looking option is not always the cheapest. And moderated sessions cost more for the same five people, mostly in staff time, because someone has to run each one live.

Ranges by approach

• Colleagues. A hallway test with people who have not seen the feature costs only a few hours. Colleagues know too much and are too polite to be your only testers, but they catch the obvious problems for free.
• Strangers you recruit yourself. The main cash cost is the incentive. The User Interviews incentives report, based on nearly 20,000 projects, puts the typical rate at $80 an hour for a remote consumer session and recommends $100 an hour as a baseline for professionals. Specialists and executives cost more.
• A testing platform with its own participant panel. Recording, task setup and recruiting come bundled, charged by subscription, per participant or both. Prices vary by plan, session length and audience, and business participants cost more than consumers.
• An agency or consultant. They recruit, moderate and deliver a report. MeasuringU’s overview of usability test costs puts a contractor running 5 to 10 moderated consumer sessions under $10,000 and a moderated study with 5 to 8 consumers at $10,000 to $25,000. The figures are from 2018, so treat them as a floor.
• An enterprise research platform. Annual contracts negotiated with sales, built for research teams running many studies with specific audiences. Prices are not public.
• Synthetic users. AI that simulates users is cheap per run and useful while building, but it does not get confused or give up the way people do. The real vs synthetic users comparison covers where it fits.

What Hallway Test costs

The first test is free: one usability test in exchange for a 30-minute feedback call, with no credit card. The planned price after public launch is $29 per test, with no subscription or tiers. Every test includes:

• one product flow, tested by one fresh in-house tester with B2+ English;
• a session of up to 30 minutes with screen recording, webcam and voice think-aloud;
• a timestamped transcript and the friction points, delivered into your coding agent’s context within 24 hours.

There is no recruiting or scheduling on your side: your coding agent describes the flow in one sentence and reads the results. The tokens it spends doing that are billed by your own AI provider. The pricing page has the full details.

How to spend less without learning less

• Test five people, not fifteen. Spend the rest on a second round after the fixes.
• Use unmoderated sessions for straightforward flows. NN/g measured them at 20% to 40% cheaper, with about 20 staff hours saved.
• Test one flow at a time. A focused 15-minute task costs less per participant and produces clearer findings than a tour of the whole product.
• Let automated checks catch the obvious bugs first. Paid sessions should go to questions only a person can answer, not to a broken link a script would have found.
