How to use the Maintenance Calorie Calculator
- Select the requested method and measurement system where available.
- Enter measurements using the units shown in each label.
- Select Calculate or press Enter.
- Review the method, source, assumptions, limitations, and visible safety note.
Worked example
A 1,600 kcal/day BMR with a 1.55 activity estimate produces about 2,480 maintenance kcal/day.
Understanding the result
Nearby activity estimates provide context rather than a recommended intake range.
Assumptions
- Adult equation inputs are appropriate.
- Activity remains broadly consistent.
Limitations
- Activity labels cannot capture all movement.
- Measured expenditure can differ.
Sources and method references
- Mifflin–St Jeor resting-energy equation (1990). Population equation; measured resting expenditure can differ.
Frequently asked questions
Why is maintenance energy higher than BMR?
The result is an educational estimate based on the selected method and entered assumptions. Individual measurements, needs, and outcomes vary.
Does CalculatorCheck store inputs from the Maintenance Calorie Calculator?
No. The calculation runs locally in your browser; entries are not saved, transmitted, or added to the page URL.
Is this medical or dietary advice?
No. It does not diagnose, treat, or prescribe for any condition.
