TDEE Calculator

Estimate total daily energy expenditure (TDEE) — your maintenance calories — from BMR and an activity multiplier.

Your inputs

These formulas were developed for adults.

Results

Estimated TDEE

2,556 kcal/day

BMR (Mifflin–St Jeor)
1,649 kcal/day
Per week
17,889 kcal

≈Estimate based on the stated model and assumptions

Notes for this result

  • This is a population-level estimate for adults, not a diagnosis. Discuss health decisions with a qualified professional.
  • Activity multipliers are broad averages; track your weight over a few weeks to calibrate.

Inputs are never added to links for financial, salary or health calculators.

What this calculator does

TDEE adds the energy of daily activity and exercise to your basal metabolic rate. It is the starting point for any calorie plan.

Formula and method

TDEE = BMR (Mifflin–St Jeor) × activity factor (1.2 sedentary … 1.9 extra active)

Worked example

Calculated by this tool with its default inputs:

Inputs

  • Units: Metric (kg, cm)
  • Sex (used by the formula): Male
  • Age: 30 years
  • Weight: 70 kg
  • Height: 175 cm
  • Activity level: Moderately active (3–5 days/week)

Results

  • Estimated TDEE: 2,556 kcal/day
  • BMR (Mifflin–St Jeor): 1,649 kcal/day
  • Per week: 17,889 kcal

How to read the results

Eating around your TDEE should keep weight roughly stable; track your weight for 2–3 weeks to calibrate.

Assumptions and limitations

  • Activity multipliers are broad averages and often overestimate for people who exercise but sit most of the day.
  • An estimate for healthy adults, not a diagnosis or medical advice. Consult a qualified health professional about your personal situation.

Health results are general estimates for adults and do not replace medical advice, diagnosis or treatment. Speak to a qualified health professional about your personal situation, especially during pregnancy or if you have a medical condition.

Questions

Which activity level should I pick?

If unsure, choose one level lower than you think — people commonly overestimate activity.
