Calorie Calculator

Estimate BMR, maintenance calories and goal calories.

How Calorie Calculator works

Estimate BMR, maintenance calories and goal calories. The calculator uses a transparent formula and keeps the calculation in your browser.

BMR = 10W + 6.25H − 5A + S; TDEE = BMR × activity factor.

Enter realistic values, calculate, then review the formula and supporting statistics shown with the result.

A calculator gives an estimate based on its assumptions. Real-world outcomes can differ because inputs and circumstances change.

Calorie needs vary between people. This is an estimate, not a prescription.

Are calculator results exact?

They are estimates based on the selected formula and the values you enter.

Does the website send my calculation to a server?

The calculator logic runs in your browser and does not require an external calculation API.
