Understanding the Calorie Calculator

Estimate the daily calories required to maintain, lose, or gain weight. Based on the Mifflin-St Jeor equation, widely considered the most accurate BMR formula.

Guide

How to use the Calorie Calculator

1Select your gender, unit system, and age.
2Input your height and current weight.
3Choose your activity level from Sedentary to Extra Active.
4View your daily calorie targets for weight maintenance, loss, or gain.

Applications

Common Use Cases

Weight Loss: Creating a safe caloric deficit.

Bulking: Determining surplus needs for muscle gain.

Maintenance: Finding your TDEE (Total Daily Energy Expenditure).

The Maths Behind the Calculation

BMR = 10W + 6.25H - 5A + S

We first calculate Basal Metabolic Rate (BMR) using weight (W), height (H), and age (A). We then multiply by an activity factor. S is +5 for men and -161 for women.
