A calculation will not run
Check that every required value is present. Values cannot be negative, selling price must be higher than variable cost for break-even calculations, and a target margin must be below 100%.
Ads are unavailable
Calculators remain usable when ads are offline or fail to load. Rewarded features are granted only after the ad provider confirms completion. You can try again later without losing the main result.
Change currency or decimals
Open Settings in the app and choose Currency or Decimal places. Changing currency affects display only and does not convert values.
Delete local information
Delete one calculation from History, use Clear calculation history to remove all results, or use Reset preferences for theme, currency and favourite settings.
