How this calculator works
The calculator estimates your resting metabolism with the Mifflin-St Jeor equation, then multiplies it by an activity factor to get total daily energy expenditure.
Formula
TDEE = BMR × activity factor
Example
A moderately active 30-year-old man who weighs 70 kg and is 175 cm tall burns about 2,556 kcal a day.
When to use it
- Understanding your daily energy needs
- Planning meals for training
- A starting point to discuss with a dietitian
Frequently asked questions
How accurate are calorie estimates?
Equations such as Mifflin-St Jeor are usually within about 10% for most adults, but individuals vary. Watch how your weight changes over a few weeks and adjust from there.
Which activity level should I choose?
Pick the level that matches a typical week, not your most active one. Most people with desk jobs who exercise a few times a week fit the light or moderate level.
