How it works
Formulas apply standard published equations or fee schedules in client-side JavaScript — not personalized medical or tax advice.
Formula
TDEE ≈ BMR × activity factor (e.g. 1.2 sedentary up to 1.9 very active).
How to use TDEE Calculator
- Enter measurements or body stats in the units shown (toggle ft/in vs metric if available).
- Select presets such as activity level, fee tier, or coat count.
- Submit or live-update to refresh results.
- Write down outputs with a margin buffer for waste, taxes, or medical variance.
Worked examples
Concrete numbers and cases you can check against the tool above.
Moderate deficit
BMR 1600 × activity 1.55 ≈ 2480 TDEE; target 2180 kcal/day for roughly a 300 kcal deficit.
When to use TDEE Calculator
Calorie targets for fat loss or muscle gain need TDEE, not guesswork from generic 2000-calorie labels.
Common use cases
- Set a 300-calorie deficit for sustainable weight loss.
- Fuel marathon training weeks without undereating.
- Compare sedentary vs active job TDEE side by side.
Inputs and outputs
- Feet, inches, pounds, or metric equivalents
- Numeric results with units

Frequently asked questions
- Is this medical or tax advice?
- No. Due dates, TDEE, and paycheck outputs are estimates; consult clinicians, IRS guidance, or payroll for official figures.
- Do marketplace fees change?
- Platforms update fee tables; treat results as planning approximations and verify on seller dashboards.
- Should I add waste factor?
- Yes for concrete, tile, and mulch — many pros add 5–10% beyond raw calculator output.
