Hold the cohort definition constant
All users start in the same period and are measured against the same meaningful return event.

Your inputs
Turn return counts into a comparable retention curve
Use one cohort definition and one return event across all periods. Enter user counts, not percentages, so the tool can validate the curve.

How it works
Calculate the curve
Each retained count is divided by the original cohort size, with period-to-period loss shown separately.
Choose one diagnostic cut
The result recommends a single first segmentation so a small cohort is not fragmented beyond usefulness.
Frequently asked questions
Should retention be measured from signup?
Signup cohorts are common, but the return event should represent meaningful product value. Consider activation cohorts when signup alone is weak.
Why use the original cohort as the denominator?
Classic cohort retention compares every later period with the starting group, making curves comparable over time.
Can retained users increase in a later period?
Yes for return-based retention if dormant users come back. This simple planner accepts non-monotonic counts as long as none exceed the starting cohort.
How large must a cohort be?
There is no universal minimum. Small cohorts are directional and should not be split into many segments or treated as precise population estimates.
