Common questions

Why is my result different from another calculator?

Different calculators use different equations (Mifflin–St Jeor, Harris–Benedict, Katch–McArdle, etc.) and different activity multipliers. Small differences in inputs and rounding also affect results. All results are estimates.

Is my data stored or sent anywhere?

No. All calculations happen in your browser. No data is sent to any server. Your inputs are saved only in your browser's localStorage so the form is pre-filled on your next visit. See our Privacy Policy for full details.

Can I use the calculator on mobile?

Yes. The site is fully responsive and works on all modern browsers including Chrome, Safari, Firefox, and Edge on iOS and Android.

My weight isn't changing at the suggested calories. What should I do?

The result is an estimate based on population averages. Track your intake accurately for 2–4 weeks and adjust by 100–200 Cal/day based on the trend you see. For persistent issues, consult a registered dietitian.
