Exclude trials still in progress. Signup or a card on file is not a confirmed payment.

How it works

Conversion = paid trials ÷ mature trials × 100. Target = ceiling(mature trials × target rate).

Worked example

40 payments among 200 mature trials give 20%; a 25% target would require 50 payments.

Assumptions and limits

Exclude trials still in progress. Signup or a card on file is not a confirmed payment.

Frequently asked questions

How do I use the trial to paid conversion calculator?

Measure how many trials with completed windows converted into paid subscriptions and how many payments are needed for your target.

Why wait for the trial window to end?

Users still within the trial have not had the same opportunity to pay. Mixing them artificially lowers the rate.

Do I need an account and are my inputs uploaded?

No account is required. Calculations run in your browser. Entered numbers and text are not included in tool analytics events; only the tool ID, language, and action are recorded.
