Estimate daily calorie target from maintenance calories and desired deficit.
Formula and method
This calculator computes Daily target, Weekly deficit directly in your browser without sending data to an external server.
Mathematical formula
- Daily target:
deficit>=maintenance ? NaN : maintenance-deficit - Weekly deficit:
deficit>=maintenance ? NaN : deficit × 7
Variables and parameters
- Maintenance calories (maintenance): default value 2400 cal/day.
- Deficit (deficit): default value 500 cal/day.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
