How it works and an example to tryShow less

How to use the result

Trials are visitors times sign-up rate; activated trials times activation; paying times conversion. MRR is paying accounts times revenue per account. A relative lift on any step raises paying accounts by the same share.

Example to try

40,000 visitors at 3% sign-up, 45% activation and 25% conversion yield 135 paying accounts, £8,100 of new MRR a month. A 10% lift on any step adds about £810.
