AI calculators

Separate usage-based inference costs from an AI product’s subscription economics.

Choose the right model

Use AI API Cost when you know input and output token volumes and provider rates. Use AI App Profit when you have a blended cost per request, paying-user count, subscription price, and other monthly costs. The cost-per-request model does not automatically import the token estimate; enter a consistent blended cost yourself.

Use your own assumptions

All prefilled rates are editable examples. Replace them with your actual billing agreements and analytics. Keep the units and reporting period consistent when comparing models. Monthly annualization assumes twelve identical months; it is not a forecast.
