Calorie & TDEE Calculator

Estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) based on your activity level.

Daily Calories (TDEE)

2,170 kcal

Base metabolic rate (BMR)
1,400 kcal

Assumptions

How it's calculated

BMR (Mifflin-St Jeor): 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 (male) or −161 (female). TDEE = BMR × activity multiplier.

Worked example

A 30-year-old female, 68kg, 165cm, moderately active has a BMR and TDEE shown live above.

Frequently asked questions

Which BMR formula does this use?

The Mifflin-St Jeor equation — widely regarded as more accurate than the older Harris-Benedict formula for most adults.
