What does a test cost?

The shape of the number before you open the wizard: what drives the price of a test, what common sizes run, and why the quote you approve is the price you pay.

Every test shows its exact price in the wizard before you launch, so you never commit blind. But when you are budgeting a study, you want the shape of the number before you get there. Here it is.

How credits work

One credit is one dollar, always. You can buy credits in packs (100, 250, 500, 1000, or 2500 at a time, with bonus credits on the three larger packs), or add exactly what a single launch needs in one click. Unused credits stay in your wallet for the next test. The full mechanics are in Credits and packs.

The four things that move the price

1. How many people watch. Every participant is a real person paid for their time, so the sample size is the biggest lever. Double the people, roughly double the cost.
2. Who they are. The general population is the base rate. A shaped audience (a specific age band or gender) draws from a smaller pool, and reaching those people costs more per person. See Choosing an audience.
3. How long the video runs. Participants are paid for viewing time, so a longer video means a longer session and a higher per-person rate. A ninety-second version and a six-minute one are different budgets.
4. How long the survey is. Up to 4 questions ride inside the base estimate. Past that, each stretch of extra questions adds session time, and the pay follows.

What a test runs, roughly

For a short video, a general audience, and a short survey, a recruited test works out to about 4 credits per person. That gives you honest budgeting anchors:

• 24 people is around 100 credits.
• 48 people is around 200 credits.
• 200 people is around 800 credits.

These are approximations, and the drivers above move them. The wizard's quote is the exact price: it reflects your video, your audience, and your survey, and nothing is charged until you approve it. A paid test also has a floor of 25 credits, because below that a sample is too small to tell you anything.

What happens at settle

A test reserves credits for the full size you asked for. When it closes, you pay for the people who actually completed it: if a slot goes unfilled, the credits for it come back to your wallet automatically. You never pay for an empty seat.

Share-link tests are free

All of the above is the price of HoldFast recruiting an audience for you. If you bring your own viewers instead, sending the test out with a share link to your list or community, that costs zero credits. You pay for recruiting, not for testing.
