Cohort Retention Decay Simulator
Cohort Retention Decay Simulator: Compounds retention decay: Month 1 = 100 * (1 - 0.10) = 90; Month 2 = 90 * (1 - 0.10) = 81.
About this cohort retention decay simulator
Compounds retention decay: Month 1 = 100 * (1 - 0.10) = 90; Month 2 = 90 * (1 - 0.10) = 81 Enables rapid evaluation of advertising efficiency and campaign economics without transmitting proprietary media budget figures.
Metrics formula & attribution logic
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Calculation and parameter relationship: retainedByMonth[m]=round(initialUsers×(1−monthlyChurnPercent/100)^m,2)
Worked campaign analytics example

Illustrative output:
Input parameters & edge case boundaries
Operational constraints and validation boundaries: Parameter domains and units: initialUsers ∈ ℤ; initialUsers ≥ 0; monthlyChurnPercent ∈ [0,100]; months ∈ ℤ ∩ [1,120]; round(…,2). Results use binary64 floating-point numbers unless BigInt is stated. Result cards show up to 10 significant digits; raw output retains the serialized value.
Marketing metrics in Cohort Retention Decay Simulator implement standard industry formulas (IAB/MRC). External ad platform reporting may differ slightly due to time zone cutoffs or attribution windows.
Local metrics evaluation boundary
Formula calculations and numeric evaluations in Cohort Retention Decay Simulator run synchronously in the browser JavaScript engine with zero server telemetry.
