How the TDEE Calculator Works
Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, including your Basal Metabolic Rate (BMR) plus calories burned through physical activity and digestion.
Formula
BMR (Mifflin-St Jeor) — Women: 10×kg + 6.25×cm − 5×age − 161
TDEE = BMR × activity multiplier

Frequently Asked Questions
What is TDEE used for?
TDEE is used as the baseline for setting calorie targets — eating below it typically leads to weight loss, eating at it maintains weight, and eating above it leads to weight gain.
How accurate is a TDEE calculator?
TDEE calculators provide a reasonable starting estimate, but actual energy expenditure varies by individual metabolism, so it's best to track results over a few weeks and adjust as needed.
How much of a calorie deficit is safe for weight loss?
A deficit of 500 calories/day is a common, moderate approach that typically results in about 1 pound of weight loss per week. Larger deficits should be used cautiously and ideally under medical supervision.
