TDEE calculator
Estimate daily maintenance energy from resting metabolism and activity.
A clear answer. Here’s how.
Estimated total daily energy expenditure = Mifflin–St Jeor resting energy × physical activity level (PAL). The presets are representative points within FAO adult lifestyle ranges: light 1.40–1.69, active 1.70–1.99, vigorous 2.00–2.40. Choose for your whole daily lifestyle, including work and leisure. Individual needs can differ substantially; no weight-loss deficit is prescribed.

Worked example
A fixed demonstration, separate from the values you enter above.
- Weight
- 75
- Weight unit
- Kilograms (kg)
- Height
- 175
- Height unit
- Centimetres (cm)
- Age (years)
- 30
- Sex used by the equation

Example result
- Estimated resting energy
- 1,533 kcal/day
- Activity multiplier (PAL)
- 1.55
- Estimated maintenance energy
- 2,376 kcal/day
- Energy in kilojoules
- 9,940 kJ/day
A rough maintenance estimate. Actual needs vary; this is not a prescribed intake or weight-loss target.
