Maintenance Calorie Calculator

Find out how many calories you need per day to maintain your current weight. The calculator uses the Mifflin-St Jeor equation and your activity level — and shows what happens to the number if you want to lose or gain instead.

📌 This is an estimate based on the Mifflin-St Jeor equation, accurate to within about ±10% for most adults. Individual metabolism, body composition and medical conditions can shift real needs. Calorie targets below 1,200/day are not shown — consult a professional before aggressive deficits.

Finding your true maintenance

A calculator gives you a starting estimate — your real maintenance is confirmed by data. Eat at the calculated number for two to three weeks while weighing yourself every morning. If your weekly average weight stays flat, the number is right. If you drift up or down by more than half a pound per week, adjust intake by 150–250 calories and repeat. This simple feedback loop beats any formula, because it captures your individual metabolism and real activity.

Maintenance is also the anchor for every other goal: a cut is simply maintenance minus 250–500 calories, and a lean bulk is maintenance plus 250–500. Use the TDEE calculator to see the full activity-level breakdown, the calorie deficit calculator to plan a cut, and the macro calculator to split your calories into protein, carbs and fat.
