TDEE Calculator
Estimate your Total Daily Energy Expenditure (TDEE) — the number of calories you burn per day. This calculator uses the Mifflin–St Jeor equation to estimate BMR (Basal Metabolic Rate), then multiplies by an activity factor to estimate TDEE.
Inputs explained:
• Sex: used in the BMR formula.
• Age: in years.
• Height: cm (metric) or ft/in (imperial).
• Weight: kg (metric) or lb (imperial).
• Activity level: multiplier for daily movement and training.
Output includes maintenance calories (TDEE) + simple cut/bulk targets.
• Sex: used in the BMR formula.
• Age: in years.
• Height: cm (metric) or ft/in (imperial).
• Weight: kg (metric) or lb (imperial).
• Activity level: multiplier for daily movement and training.
Output includes maintenance calories (TDEE) + simple cut/bulk targets.
If provided, we’ll also show a Katch–McArdle estimate (uses lean mass).
Quick note: TDEE is an estimate. Real maintenance can vary. Track weight for 2–3 weeks and adjust calories by ~100–200 kcal if you’re not moving toward your goal.
TDEE Calculator — Description
The TDEE Calculator estimates how many calories you burn per day based on your age, sex, height, weight, and activity level. It first calculates your BMR (Basal Metabolic Rate) using the Mifflin–St Jeor equation, then multiplies by an activity factor to estimate TDEE (maintenance calories). The tool also suggests simple targets for a calorie deficit (cut) or surplus (lean bulk).
This calculator is useful for weight loss planning, muscle gain planning, and understanding how changes in activity level affect your daily calorie needs.
