Formula steps

  1. Estimate resting energy with the Mifflin-St Jeor equation.
  2. Multiply BMR by the selected activity factor.
  3. Use the activity-adjusted result as estimated total daily energy expenditure.

How to use the TDEE Calculator

  1. Enter the requested measurements, dates, lab values, or workout details.
  2. Check that the units and formula assumptions match what the tool is asking for.
  3. Press the calculate button to see the answer, supporting metrics, and formula steps.
  4. Read the estimate with the health disclaimer in mind, then copy the result if you need it for notes.

What people use it for

Estimate maintenance calories before setting macro targets.

Compare sedentary, light, moderate, very active, and extra active activity factors.

Use TDEE as the base for calorie, protein, carbohydrate, and fat planning.

Adjust a starting estimate with real weight trends and intake tracking over time.

Quick examples

Moderate activity

Female formula, age 32, 165 cm, 68 kg: BMR 1,390.25 x 1.55

About 2,155 kcal/day

Sedentary

Male formula, age 45, 180 cm, 88 kg: BMR 1,785 x 1.2

2,142 kcal/day

Very active

Female formula, age 27, 172 cm, 63 kg: BMR 1,409 x 1.725

About 2,431 kcal/day

Moderate male check

Male formula, age 35, 178 cm, 82 kg: BMR 1,762.5 x 1.55

About 2,732 kcal/day

Frequently asked questions

Plain-language answers about when to use the estimate, what the formula means, what it cannot decide for you, and how privacy works.

When should I use the TDEE Calculator?

Use it for simple educational checks, trend tracking, or planning tasks like these: Estimate maintenance calories before setting macro targets. Compare sedentary, light, moderate, very active, and extra active activity factors. It can help you understand a number, but it cannot explain your whole health situation.

What do the main TDEE Calculator inputs mean?

Enter the formula sex setting, age, height in centimeters, weight in kilograms, and the activity level that best describes a normal week. The formula sex setting chooses the +5 or -161 Mifflin-St Jeor adjustment. The activity level multiplies BMR by a broad factor, so pick the average week rather than your best workout day.

What is the TDEE Calculator doing with my inputs?

In plain language: BMR = 10 x weight kg + 6.25 x height cm - 5 x age + formula-sex adjustment (+5 or -161). TDEE = BMR x activity factor: 1.2 sedentary, 1.375 light, 1.55 moderate, 1.725 very active, or 1.9 extra active. Read the result together with the notes on the page, because health and fitness numbers often need personal context.

How should I read the TDEE Calculator result?

Read TDEE as estimated maintenance calories per day for the inputs and activity factor you chose. It is not a promised weight-change number, medical diet order, pregnancy plan, eating-disorder recovery plan, or exact metabolism measurement. Real-world trends can move the useful target up or down.

What activity factors does this TDEE calculator use?

It uses common planning factors: 1.2 for sedentary, 1.375 for light activity, 1.55 for moderate activity, 1.725 for very active, and 1.9 for extra active. These are broad multipliers, not wearable-tracker measurements.

Is TDEE the same as BMR?

No. BMR estimates resting energy before normal movement and exercise. TDEE starts with BMR, then multiplies it by an activity factor to estimate total daily energy expenditure.

How should I choose an activity level?

Choose the level that describes your usual week, not your hardest training day. If work, steps, workouts, or caregiving vary a lot, start conservative and compare the estimate with real weight and intake trends.

Is TDEE my weight-loss target?

No. TDEE is the estimated maintenance anchor. A weight-loss, gain, or macro target should be chosen separately and carefully, especially if you have medical conditions, a history of disordered eating, pregnancy, or sport-performance needs.

Why can my real maintenance calories be different?

Activity labels are broad, food tracking can be off, body composition varies, and weight changes include water and glycogen shifts. Use the calculator as a starting estimate, then adjust slowly with real-world evidence.

Can I use TDEE for medical or pregnancy nutrition?

Use qualified medical or nutrition guidance for pregnancy, diabetes, kidney disease, heart disease, eating-disorder recovery, medication changes, or any plan where under-eating or over-eating could be unsafe.

Can I use this as medical advice?

This calculator gives an educational maintenance-calorie estimate only. It is not a medical diet order, eating-disorder tool, pregnancy nutrition plan, sport fueling prescription, or guarantee of weight change. Use the calculator as a learning tool, then ask a qualified professional about decisions that affect care, pregnancy, medication, nutrition, or safety.

What should I double-check before trusting the result?

Check the units, date, and personal details before reading the answer. For example, pounds and kilograms, inches and centimeters, or a wrong activity level can change the result quickly. If the number feels surprising, rerun it slowly and compare it with the examples.

Does the site save my health inputs?

No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
