Macro Calculator

Estimate daily calories, protein, carbohydrate, and fat targets for cutting, maintaining, or gaining. BodEvo builds targets from published equations — Mifflin-St Jeor, and Katch-McArdle when a body-fat estimate is provided — with the assumptions shown, not hidden. Adjust activity level, goal rate, and protein preference and see the numbers update instantly.

BodEvo runs in your browser — local-first, free, no account required. Estimates for educational purposes, not medical advice.
