About this tool
Estimate daily calories from age, height, weight and activity, then split protein, carbs and fat. Runs locally. BMR & TDEE Calculator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- BMR & TDEE Calculator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
