TDEE Calculator
Estimate your Total Daily Energy Expenditure (TDEE) using BMR and activity level. Informational only.
Informational only. Activity multipliers are approximations and vary by individual.
Privacy: calculations run locally in your browser. No inputs are stored or sent to a server.
How it works
1) Calculate BMR via Mifflin–St Jeor.
2) Multiply by an activity factor to estimate TDEE.
TDEE = BMR × activity multiplier
Examples
- Male 30y, 175 cm, 70 kg, moderate (1.55) → TDEE ≈ 2,556 kcal/day
- Female 30y, 165 cm, 60 kg, light (1.375) → TDEE ≈ 1,815 kcal/day

FAQ
- What is TDEE?
TDEE (Total Daily Energy Expenditure) is an estimate of how many calories you burn per day including activity.
- How is TDEE calculated here?
This tool estimates BMR using Mifflin–St Jeor, then multiplies it by an activity factor.
- Can I use TDEE for weight loss or gain?
It can be a starting estimate. Real needs vary, so adjust based on actual weight trends over a few weeks.
- Is this medical advice?
No. This is an informational estimate only.
- Is my data stored?
No. All calculations run locally in your browser.
