Health notice

Method used: Mifflin-St Jeor BMR estimate with activity multipliers. This tool is a non-diagnostic estimate for educational use only and is not medical advice. Consult a qualified doctor or registered dietitian for accurate, personalized guidance.

Formula and method

BMR (male) = 10×weight + 6.25×height − 5×age + 5 | BMR (female) = 10×weight + 6.25×height − 5×age − 161 | TDEE = BMR × Activity

Calorie Calculator applies the formula BMR (male) = 10×weight + 6.25×height − 5×age + 5 | BMR (female) = 10×weight + 6.25×height − 5×age − 161 | TDEE = BMR × Activity to your entered values and returns an immediate result that matches this tool's use case.

Example calculation

These examples show realistic calorie calculator scenarios so you can validate inputs and interpret outputs with confidence.

Example 1

A 30-year-old male at 72 kg and 175 cm on a lightly active schedule has an estimated daily maintenance calorie target.
