Calorie Calculator
Calculate your daily calorie needs using the Mifflin-St Jeor equation. Enter your stats and activity level to find your TDEE (Total Daily Energy Expenditure) and calorie targets for different goals.
How We Calculate This
Uses the Mifflin-St Jeor equation: BMR = 10×weight(kg) + 6.25×height(cm) - 5×age + constant (men: +5, women: -161). TDEE = BMR × activity multiplier.
Frequently Asked Questions
What is TDEE?
TDEE (Total Daily Energy Expenditure) is the total calories you burn per day, including BMR plus activity. It's the calories needed to maintain your current weight.
What is BMR?
BMR (Basal Metabolic Rate) is the calories your body burns at complete rest - just to keep your organs functioning. It's typically 60-75% of your TDEE.
How many calories to lose weight?
A 500 calorie deficit per day equals about 1 lb loss per week. A 1000 calorie deficit equals ~2 lbs/week. Don't go below 1200 (women) or 1500 (men) calories.
How accurate is this calculator?
The Mifflin-St Jeor equation is considered the most accurate for most people, but individual metabolism varies. Use this as a starting point and adjust based on results.
