Daily Calorie Estimate

How this calculator works

The entered BMR is multiplied by a rough activity factor.

Change one assumption at a time to see which inputs have the greatest effect on the estimate.

Worked example

A 1,500-calorie BMR at 1.2 produces an 1,800-calorie estimate.

Limitations

Educational estimate only. This calculator does not diagnose any condition, provide medical advice, prescribe treatment, or replace a doctor or qualified healthcare professional. Activity factors are broad averages and should not guide weight change, illness, pregnancy, or eating-disorder care without professional advice.

Review this educational estimate against current quotes, official information, and your own budget before making a financial decision.
