Estimate BMR and maintenance calories
What this estimate is for
BMR is a starting point for planning. Real energy needs change with sleep, training, illness, medication, menstrual cycle, body composition, and daily movement that formulas cannot see.
Do not use this page to set an aggressive diet. For medical conditions, pregnancy, eating disorder history, or unexplained weight change, work with a qualified professional.
Formula used
This page uses the Mifflin-St Jeor equation because it is common in modern nutrition calculators.
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
TDEE ≈ BMR × activity factor
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
TDEE ≈ BMR × activity factor
