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: 2,420 kcal/day

In this lightly active adults example, the estimated maintenance target is 2,420 kcal/day, which gives you a practical daily baseline before making nutrition changes.

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

Result: 2,549 kcal/day

For this second lightly active adults scenario, the projected maintenance level comes out to 2,549 kcal/day, making it easier to benchmark daily calorie needs in the same context.

FAQ

Key questions answered

How accurate is this light activity calorie calculator?

This light activity calorie 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 light activity calorie 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 light activity calorie 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 light activity calorie calculator?

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