What Is a Calorie Calculator?

A calorie calculator estimates how many calories your body may need each day. It uses your age, sex, height, weight and activity level to estimate your maintenance calories.

How This Calculator Works

This calculator uses the Mifflin-St Jeor equation to estimate BMR, then multiplies it by your selected activity level to estimate daily maintenance calories. Goal calories are adjusted up or down from maintenance.
