# Prepaid Wallet Burn Rate Calculator — Forecast Credit Depletion & Deferred Revenue | Enso

> Forecast when your customers' prepaid credit wallets will run out. Model deferred revenue burn-down, growth-adjusted depletion dates, and auto top-up thresholds over 12 months.


AI companies that sell prepaid credit wallets face a forecasting problem unique to their billing model: revenue that arrives as cash months before it's earned, burning down at a rate that's hard to predict when usage is growing.

The calculator above lets you model depletion dates for any wallet size and burn rate — including growth-adjusted projections over 12 months. Use it to set auto top-up thresholds that trigger renewal conversations before customers hit zero, and to model the deferred revenue liability on your balance sheet.
