Macro Calculator

Calculate your optimal daily protein, carbohydrates, and fat intake based on your goals _ weight loss, maintenance, or muscle building.

How it works

Calories = TDEE ± deficit/surplus. Protein = 1.6–2.2 g per kg. Fat = 20–35% of calories ÷ 9. Carbs = remaining calories ÷ 4.

Worked example

On 2,200 calories for fat loss at 80 kg: 160 g protein (640 cal), 70 g fat (630 cal), leaving 930 calories, or about 230 g of carbohydrate.

Frequently asked questions

What macro split is best for fat loss?

Roughly 40% carbs, 30% protein, 30% fat works for most people, but protein is the only macro worth being strict about — set it at 1.6–2.2 g/kg and split the rest to taste.

Do I need to hit macros exactly?

No. Landing within about 10 g of protein and 100 calories of your target daily is enough. Weekly consistency matters far more than any single day.

Should macros change on rest days?

Only slightly. Many people shift 30–50 g of carbs from rest days into training days while keeping calories and protein constant across the week.
