Estimated with the Mifflin–St Jeor equation. Individual needs vary, so treat it as a starting point.

Formula

Men: BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5. Women: BMR = 10 × weight + 6.25 × height − 5 × age − 161. TDEE = BMR × activity factor.

About this calculator

BMR is the energy your body uses at complete rest. Multiplying by an activity factor estimates total daily energy expenditure. This is general information, not medical advice.

Amounts are shown without a currency symbol, so the calculator works for any currency: enter all values in the same one.

Frequently asked questions

How many calories should I eat to lose weight?

A moderate deficit below your maintenance calories is the usual approach. Speak to a doctor or dietitian before large changes, especially with a medical condition.
