Estimate basal metabolic rate and daily calorie needs from body measurements and activity.
A general population estimate, not personalised diet or medical advice. Energy needs vary.
How to use this calculator
Enter your values above and the result updates instantly. You can change the inputs as often as you like, and use Reset to restore the example values.
About the result
Estimate basal metabolic rate and daily calorie needs from body measurements and activity. The calculation runs in your browser; the values you enter are not sent to this website.
What the Calorie and TDEE Calculator does
Estimate basal metabolic rate and daily calorie needs from body measurements and activity. It is designed for understanding a general health or activity estimate from the measurements you provide. The calculator uses the values you enter to produce estimated bmr, estimated maintenance calories and illustrative modest deficit without sending your information to the server.
This page is most useful when you want a quick answer and a repeatable way to compare alternatives. Change one input at a time to see which factor has the greatest effect.
How the calculation works
The calculation starts with sex used by equation, age, weight, height and activity level. It applies the relevant health relationship to calculate estimated bmr, estimated maintenance calories and illustrative modest deficit. Results update in your browser whenever an input changes.
Inputs used
- Sex used by equation
- Age
- Weight
- Height
- Activity level
Results provided
- Estimated BMR
- Estimated maintenance calories
- Illustrative modest deficit
Practical tip: Use recent, accurately measured inputs and treat the output as one indicator rather than a diagnosis.
Example calorie and tdee calculator setup
The calculator opens with the example values below. They demonstrate the expected format and give you a starting point before entering your own figures.
- Sex used by equation
- male
- Age
- 35 years
- Weight
- 75 kg
- Height
- 175 cm
- Activity level
- 1.55
After entering the values, review estimated bmr, estimated maintenance calories and illustrative modest deficit in the results panel. Use Reset whenever you want to return to this example.
Understanding your result
Read the result alongside the inputs that produced it. A precise-looking number is still only as useful as the information entered. For comparisons, keep every input the same except the one factor you want to test.
