TDEE Calculator
Calculate your Total Daily Energy Expenditure
What is it?
TDEE (Total Daily Energy Expenditure) estimates the total number of calories you burn in a day, combining your BMR with your activity level. It's commonly used as a starting point for weight loss, maintenance, or gain plans.
Formula
TDEE = BMR × Activity Multiplier (1.2 sedentary to 1.9 super active)
Formula Explanation
TDEE starts from your BMR (the calories you burn at complete rest) and scales it up by an activity multiplier that reflects how much you move in a typical week — from 1.2 for a mostly sedentary lifestyle to 1.9 for very intense daily activity. The higher the multiplier, the more calories your daily routine adds on top of your resting burn.
Example Calculation
A person with a BMR of 1,700 kcal/day who exercises 3–5 days a week (activity multiplier 1.55) has a TDEE of 1,700 × 1.55 ≈ 2,635 kcal/day — their estimated total daily calorie burn.
How to Use
- Enter your gender, age, height, and weight.
- Select your activity level.
- View your TDEE and calorie targets for maintenance, mild/aggressive weight loss, and weight gain.
Benefits
- Gives you a realistic daily calorie number that accounts for your actual activity, not just resting burn.
- Provides ready-made targets for weight loss, maintenance, and weight gain in one result.
- Helps set expectations before starting a diet or training plan.
Use Cases
- Setting a calorie target when starting a weight loss or muscle-gain program.
- Checking whether your current eating habits roughly match your goals.
- Re-estimating calorie needs after a significant change in activity level.
What Your Result Means
Your TDEE is the calorie level at which your weight should stay roughly stable. Eating consistently below it creates a deficit for weight loss; eating above it creates a surplus for weight gain. The mild and aggressive loss figures reflect common 300–600 kcal/day deficits used in most weight-management plans.
Tips
- Be honest about your activity level — most people overestimate it, which inflates TDEE.
- Reassess your TDEE every few weeks based on actual weight trend, not just the formula.
- Prefer a moderate deficit (300-500 kcal) over an aggressive one for long-term sustainability.
Common Mistakes
- Selecting a higher activity level than actually matches your week, overestimating calorie needs.
- Treating the TDEE number as exact rather than an estimate that needs real-world adjustment.
- Cutting calories far below the aggressive loss figure, which can be unsustainable and unhealthy.
FAQs
Which activity level should I choose?
Pick the one that best matches your typical week — most people overestimate their activity level, so when unsure, choose the lower option.
How accurate is TDEE?
TDEE is an estimate based on population averages; actual calorie burn varies by individual metabolism, so use it as a starting point and adjust based on real results over a few weeks.
Should I eat exactly at my TDEE?
Eat at your TDEE to maintain weight, below it to lose weight, and above it to gain weight — most plans use a moderate 300-600 kcal adjustment rather than a large one.
What is the difference between TDEE and calorie needs for muscle gain?
For muscle gain, most people eat slightly above TDEE (around a 300 kcal surplus) combined with resistance training, rather than a large surplus which mostly adds fat.
Does TDEE change as I lose or gain weight?
Yes — TDEE is based on your current weight and activity, so it should be recalculated periodically as your weight changes.
Why is my TDEE different from an app I used before?
Different tools may use different BMR formulas or activity multiplier definitions, which can produce modestly different TDEE estimates — small differences are expected.
Is TDEE the same for everyone at the same weight?
No, TDEE also depends on age, height, gender, and activity level, so two people at the same weight can have different TDEE values.
Should athletes use a different method?
Very active athletes may find this formula underestimates their needs; tracking actual intake against weight trend over a few weeks gives a more personalized number.
