"What retention rate means I have product-market fit?" It's one of the most common questions founders ask, and the honest answer frustrates them: there isn't one. Any specific number, 40% at day 30, 80% annual logo retention, is meaningless without knowing your model. Chasing a universal benchmark leads you to either false comfort or false panic.
What actually signals fit is not a single retention rate. It's the shape of the retention curve.
The signal is the shape, not the number
Plot the percentage of each cohort still active over time. You get one of two shapes:
- A curve that decays toward zero. Every cohort eventually leaves. No amount of new acquisition fixes this, you're filling a leaky bucket. This is the absence of fit.
- A curve that flattens above zero. After early drop-off, a stable group keeps using the product indefinitely. That plateau is a segment of users who found lasting value. That's product-market fit, made visible.
A product with a "low" absolute retention rate that flattens has more fit than one with a "high" rate that's still sliding downward. The plateau is the proof, not the starting height. See the retention curve vs the PMF survey for how to read it.
Why the number depends on your model
"Good" retention is defined entirely by how often your product is meant to be used:
| Model | Natural usage | What to watch |
|---|---|---|
| Daily consumer app | Every day | Day-N active retention; a flattening DAU cohort curve |
| Monthly SaaS | Weekly to monthly | Logo and net revenue retention; usage frequency holding |
| Infrequent / annual | A few times a year | Repeat rate over 6-12 months, not daily activity |
| Marketplace | Per transaction need | Repeat purchase / repeat booking rate per cohort |
Comparing your daily-app retention to a SaaS benchmark, or vice versa, tells you nothing. Compare your curve to your own past curves, and watch whether the plateau is rising.
Retention shows the "that." The survey shows the "why."
A flattening curve proves some users stay. The Sean Ellis survey tells you who they are and why, so you can find more of them. Run it free.

Retention is a lagging, behavioral signal: it shows you that users stayed, but not why, and it takes months of cohorts to read. The Sean Ellis survey is the leading complement: it tells you, right now, what share of engaged users would be very disappointed to lose you, and their open-ended answers explain the plateau in your curve. Weak retention plus a low survey score is the classic no-market-need pattern; a flattening curve plus a 40%+ score is fit you can trust.

PMFtracker runs the Sean Ellis survey and tracks your PMF score, so the plateau in your retention curve comes with a name and a reason, not just a shape.
