Formula explanation

How this calculator works

Core formula

TDEE = BMR * activity multiplier

Basal metabolic rate is estimated with the Mifflin-St Jeor equation, then scaled by your activity level to estimate total daily energy expenditure.

BMR is the energy your body uses at rest.
TDEE is the better maintenance target because it includes activity.

Examples

Real scenarios you can copy

32-year-old male, 79 kg, 180 cm

Result: 2,728 kcal/day

In this adults example, the estimated maintenance target is 2,728 kcal/day, which gives you a practical daily baseline before making nutrition changes.

41-year-old male, 91 kg, 183 cm

Result: 2,873 kcal/day

For this second adults scenario, the projected maintenance level comes out to 2,873 kcal/day, making it easier to benchmark daily calorie needs in the same context.

FAQ

Key questions answered

How accurate is this daily calorie needs calculator?

This daily calorie needs calculator is a solid maintenance-calorie estimate based on the Mifflin-St Jeor approach, but real calorie needs can still shift with routine, recovery, and body-composition changes.

What does this daily calorie needs calculator estimate?

It estimates daily maintenance calories, which is the intake most likely to keep body weight stable under the activity level you select.

Should I use this daily calorie needs calculator before cutting or bulking?

Yes. Maintenance calories are the best baseline to set before you decide whether to run a deficit or a surplus.

When should I use this daily calorie needs calculator?

Use it when you need a fast maintenance-calorie estimate for daily calorie planning and want a baseline you can later fine-tune with real progress data.
