Work Backward From Revenue to the Trial-to-Paid Rate Required

How to Use This Tool

Connect installs, trial starts and billing value to a revenue target. Calculate the app trial-to-paid conversion rate required from installs, trial-start rate, billing value and target revenue.

The failure App Paid Conversion is designed to catch

A paid-conversion target is unattainable when too few installs reach trial, even if the paywall itself performs well. The boundary is the job stated in Work Backward From Revenue to the Trial-to-Paid Rate Required; App Paid Conversion is not intended to score or transform a different workflow.

The App Paid Conversion input contract

The fields used for this specific operation are App installs, Trial start rate %, First billing value, Target first-period revenue. Keep the source values beside the App Paid Conversion result, because replacing the original would remove the evidence needed to reproduce or reverse the operation.

• For App Paid Conversion, App installs starts at 50000 in the worked case; replace that example with the matching source value.
• For App Paid Conversion, Trial start rate % starts at 20 in the worked case; replace that example with the matching source value.
• For App Paid Conversion, First billing value starts at 10 in the worked case; replace that example with the matching source value.
• For App Paid Conversion, Target first-period revenue starts at 10000 in the worked case; replace that example with the matching source value.

Worked result for App Paid Conversion

The executable case called Default decision scenario expects out: 10.0%. Verify that observation before entering real material, and then change one App Paid Conversion field at a time so an unexpected direction or formatting change can be traced to a specific input.

Reading the App Paid Conversion output

It combines app installs, trial start rate %, first billing value and target first-period revenue into one decision result using the formula explained on the page. Apply that answer only when App installs, Trial start rate %, First billing value, Target first-period revenue describe the same scope and format as the worked operation. If the source uses different units, quoting, nesting, timing or account rules, a plausible-looking App Paid Conversion output is not sufficient validation.

Assumptions attached to App Paid Conversion

• App Paid Conversion assumes that all inputs describe the same unit or reporting period unless the field explicitly says otherwise.
• App Paid Conversion assumes that the model includes only the four visible inputs and does not infer hidden platform charges.

If one of these App Paid Conversion assumptions is false, keep the result as a diagnostic rather than production or decision data, and choose an implementation that explicitly supports the missing rule.

Evidence maintained for App Paid Conversion

The recorded reference is Apple Developer — App Store Connect. Reopen that source when the definition, format, fee or policy behind App Paid Conversion changes; private configuration and downstream acceptance still have to be checked in the user's own system.

Where App Paid Conversion runs

The named operation executes in browser JavaScript without an ecech calculation API. For App Paid Conversion, local execution reduces transmission but does not control browser extensions, device security or the destination where the result is pasted, so sensitive inputs still require the user's normal handling rules.
