Results are estimates or simple arithmetic, not medical or investment advice.
Estimate daily energy expenditure by multiplying resting energy needs (BMR) by an activity factor. This is a starting estimate, not a personal measurement.
The Mifflin–St Jeor equation uses age, height and weight. Its original study involved adults; this calculator is intended for ages 19+. Choose an activity level that reflects your day-to-day routine.
Male BMR = 10 × kg + 6.25 × cm − 5 × age + 5; female BMR = 10 × kg + 6.25 × cm − 5 × age − 161. TDEE ≈ BMR × activity factor.
