Five people using your site for an hour costs $415 to $1,680 if you run the study yourself, and that number is the easy part to notice. Nielsen Norman Group priced a five-participant moderated test at that range once recruiting, incentives and a video tool are added in. The harder number is the 32 to 48 hours it takes someone on your team to plan the sessions, run five back-to-back hour-long calls, and then make sense of what they saw.
An unmoderated version is cheaper and faster on paper: $250 to $1,250 and 11 to 27 hours, because a platform runs the sessions without you in the room. Incentives alone run $80 to $250 a person for a moderated study and $50 to $150 for unmoderated, recruiting adds another $0 to $80 a head, and the analysis afterward (watching the recordings, pulling out the pattern, writing it up) takes 8 to 16 hours on top of the sessions themselves. None of that counts the week of calendar time spent finding five people who will actually show up.
The dollars are rarely what trips a founder up. The hours are, because nobody invoices you for them, so they are the easiest cost to pretend is not there. Thirty-two hours is most of a working week for whoever owns this, and that estimate assumes the sessions go well: no reschedules, no participant who freezes up on camera, no session where the thing worth hearing happens in the last two minutes after the script is finished.
What that week buys is something a conversion dashboard cannot: the moment, in someone else's words, where they stopped trusting a form, gave up hunting for a price, or clicked the wrong thing twice before leaving. A drop-off chart shows you where people quit. Five sessions show you why, which is usually smaller and cheaper to fix than the redesign everyone was about to commission.
At the other end of the market, a research agency running the whole thing, recruitment, sessions and a proper readout, prices a single phase at $10,000 to $20,000, according to MeasuringU. Recruiting and paying twenty qualified participants for a moderated study alone can run $12,000 to $15,000 before anyone has watched a single session. That is the right spend for a platform redesign across three markets. It is a strange amount to pay to find out why a signup form is losing people.
The useful middle sits between those two numbers: five participants, a script built around one real question, and someone who has watched enough sessions to tell a real pattern from one person's bad afternoon. That last part is the skill nobody prices in when they decide to run this in house. Five hours of recordings hand you plenty of opinions and very few verdicts, and reading them well is a different job from building the thing being tested.
Before choosing a platform or a participant panel, decide who is actually going to watch every session and who has the authority to act on what they find, because the $415 only pays for itself if something changes afterward. If nobody on the team has run more than one of these before, that is the moment to bring in someone who has, for the five sessions rather than the redesign that follows.
