TDEE Calculator for Fat Loss, Maintenance and Muscle Gain

Your TDEE is your Total Daily Energy Expenditure. It estimates how many calories you burn in a normal day when your body size, age, sex, and activity level are taken into account.

This number is useful because it gives you a starting point. If your goal is fat loss, you usually need to eat below your TDEE. If your goal is muscle gain, you usually need to eat slightly above it. If your goal is maintenance, your body weight should stay fairly stable around this number.

How to use your TDEE result

Do not treat the result as a perfect target. Treat it as a starting estimate. Track your body weight trend, waist measurement, training performance, energy, and hunger for two to three weeks. If your weight is stable, your maintenance estimate is close. If your weight is moving too fast or not moving at all, adjust by 100 to 200 calories.

For adults over 40, calories matter, but protein and strength training matter just as much. Losing weight without strength training can increase muscle loss. A better goal is to reduce body fat while keeping or building muscle.

Why macros matter after 40

Your calorie target tells you how much energy to eat. Your macros help decide what that energy is made of. Protein supports muscle repair, recovery, and satiety. Fat supports hormones and health. Carbohydrates support training performance and daily energy.

This calculator gives practical macro targets for maintenance, cutting, and bulking. Use them as a guide, then adjust based on your progress, schedule, training intensity, and lifestyle.

TDEE and body composition

Scale weight alone does not show the full picture. A person can lose fat and build muscle while the scale changes slowly. That is why it helps to combine your TDEE result with waist measurement, progress photos, strength numbers, and body fat estimates.

You can also use the body fat tape calculator or the skinfold body fat calculator to track progress beyond body weight.

FAQ

Is this TDEE calculator accurate?

It gives a useful estimate, but your real maintenance calories depend on your movement, training, sleep, stress, digestion, and consistency. Use the result for two to three weeks, then adjust based on real progress.

Should I eat exactly at my TDEE?

Eat close to your TDEE if your goal is maintenance. For fat loss, start with a moderate deficit. For muscle gain, use a small surplus. Extreme changes are harder to sustain.

What is the best calorie target for fat loss?

A moderate deficit usually works best. For many people, that means 300 to 500 calories below maintenance. The right number depends on your body size, training load, recovery, and how well you can stay consistent.
