About Easy Macro Calculator
Easy Macro Calculator is a free tool that helps you turn a goal, like losing fat, maintaining or building muscle, into clear daily numbers for calories, protein, carbohydrates and fat.
Why we built it
Most macro calculators hide results behind sign-ups, bury them under pop-ups or give one number without explaining where it came from. We wanted something different: fast, private, easy to read on a phone, and transparent about the math.
What makes it different
- No account needed. Your results appear instantly and update as you type.
- Private by design. Calculations happen in your own browser. Your inputs are only remembered on your device.
- Every popular diet style, from balanced and high protein to keto, Zone and Mediterranean, plus a fully custom option.
- Transparent formulas. We explain exactly how your numbers are calculated, using well-established equations like Mifflin-St Jeor and Katch-McArdle.
- Built-in safety checks, including minimum calorie levels and warnings for aggressive deficits.
