TDEE Calculator
Calculate your Total Daily Energy Expenditure (TDEE) — the total calories you burn in a day including exercise. This is your maintenance calorie number.
Formula
TDEE = BMR × Activity Factor
BMR (Mifflin-St Jeor): Male = 10W + 6.25H − 5A + 5; Female = 10W + 6.25H − 5A − 161
- TDEE Calculator gives you a fast estimate using your inputs and updates instantly when you change any value.
- Formula: TDEE = BMR × Activity Factor\nBMR (Mifflin-St Jeor): Male = 10W + 6.25H − 5A + 5; Female = 10W + 6.25H − 5A − 161
- Input definitions: • Age: the numeric age used in the calculation • Weight: the numeric weight used in the calculation • Height: the numeric height used in the calculation
- Manual method: write down each input, apply the formula step by step, then compare your manual result with the calculator output.
- Enter values using the units shown next to each input field (e.g. kg, cm, years).
- This calculator uses widely accepted health formulas and returns screening estimates only. It does not replace a diagnosis from a qualified healthcare professional.
- Compare your result with published reference ranges. Values outside the normal range warrant a conversation with your doctor.
- Practical tip: test a low, medium, and high scenario to understand sensitivity before making decisions.
Example Calculation
Inputs
- Age: 30 years
- Weight: 75 kg
- Height: 175 cm
Suppose you enter: Age = 30, Weight = 75, Height = 175. The calculator applies the formula (TDEE = BMR × Activity Factor\nBMR (Mifflin-St Jeor): Male = 10W + 6.25H − 5A + 5; Female = 10W + 6.25H − 5A − 161) and shows all output values below. Change any input field to immediately see how the result changes.
Frequently asked questions
What is the TDEE?
The TDEE Calculator is a health and wellness calculator that helps you calculate tdee values from your input data. Enter values using the units shown next to each input field (e.g. kg, cm, years).
When should I use this calculator?
Use this calculator whenever you need a quick, accurate result for tdee values from your input data without working through the arithmetic manually.
What units should I enter?
Enter values using the units shown next to each input field (e.g. kg, cm, years).
How accurate are the results?
This calculator uses widely accepted health formulas and returns screening estimates only. It does not replace a diagnosis from a qualified healthcare professional.
How do I interpret the result?
Compare your result with published reference ranges. Values outside the normal range warrant a conversation with your doctor.
How can I verify the calculation manually?
Use the displayed formula and work through the numbers step by step. If your manual result differs slightly, check rounding and unit conversions first.
Can I use this for planning and budgeting?
Yes. Run best-case, expected, and worst-case inputs to compare outcomes and make safer planning decisions.

BMR Calculator Calculate your Basal Metabolic Rate (BMR) — the calories your body burns at complete rest — using the Mifflin-St Jeor equation. Enter your sex, age, weight, and height to see your daily resting calorie needs. Calorie Calculator Find out how many calories you need each day to lose, maintain, or gain weight. This calculator estimates your BMR with the Mifflin-St Jeor equation, multiplies by your activity level to get your maintenance calories (TDEE), then adjusts for your goal so you get a daily calorie target you can actually eat to. Calorie Deficit Calculator See how fast you'll lose weight from a calorie deficit. Enter your maintenance calories (TDEE) and how much you plan to eat each day, and this calculator shows your daily deficit plus your projected weekly and monthly weight loss — and how long it takes to drop each kilogram. Macro Calculator Macro Calculator is a health and wellness calculator that helps you calculate macro values from your input data. The formula used is: Protein = 30% of target calories ÷ 4\nCarbs = 40% of target calories ÷ 4\nFat = 30% of target calories ÷ 9. Enter values using the units shown next to each input field (e.g. kg, cm, years).
