How to use the net new users calculator
Growth accounting splits the change in active users into three streams: new + resurrected โ churned. Looking at new signups alone makes the product look like it is growing, but if more people dropped out over the same period the base actually shrank. The reverse also happens: weak signups can still produce positive net growth when many previously churned users come back. Leave resurrection out and it is no longer growth accounting, so all three streams are required inputs here.
The net growth rate divides net new users by starting users. That is exactly 100 percentage points away from ending users divided by starting users, which is a retention ratio rather than a growth rate, so each result label spells out the formula it used. Ending active users is also derived by adding the net new figure shown on screen to the starting count, so the numbers on screen add up exactly.
The growth quick ratio divides new plus resurrected users by churned users, showing how many users arrive for every one lost. When churn is zero the division is undefined and the result says so. No benchmark level is built in, because what counts as healthy is quoted differently at every stage of a company.
Frequently asked questions
They were inactive in the previous period and met your active definition again this period. Fix that active definition first, whether it is a login, a purchase or a usage event, and apply it identically every period.
Yes. When churn exceeds new plus resurrected users, net new users is negative, ending active users falls below the starting count, and the net growth rate is shown as a negative percentage.
