What is Calorie Calculator?

▾

A TDEE (Total Daily Energy Expenditure) calculator estimates how many calories you burn in a day based on your Basal Metabolic Rate (BMR) and activity level. This is the daily calorie target to maintain weight — eat less to lose, eat more to gain.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Formula

f(x)Step 3: Adjust for goal: −500 kcal/day = ~0.5kg loss/week, +500 = ~0.5kg gain/week

How to Calorie Calculator

▾

1Step 1: Calculate BMR using Mifflin-St Jeor: Men: 10W + 6.25H − 5A + 5, Women: 10W + 6.25H − 5A − 161
2Step 2: Multiply BMR by activity factor (1.2 sedentary to 1.9 very active)
3Step 3: Adjust for goal: −500 kcal/day = ~0.5kg loss/week, +500 = ~0.5kg gain/week
4Step 4: Calculate macros: protein ~2.2g/kg, fat ~25% of kcal, remainder as carbs
