TDEE Calculator: estimate daily calories
Estimate your daily energy expenditure and compare maintenance, deficit and lean bulk targets.
Use this TDEE calculator to estimate how many calories you burn in a day based on sex, age, weight, height and activity level. It gives you a practical starting point for weight maintenance, gradual fat loss or controlled muscle gain.
The estimate uses the Mifflin-St Jeor equation for basal metabolic rate and then applies an activity multiplier. Treat the output as a planning reference rather than a medical assessment.
What the calculator returns
- Estimated basal metabolic rate.
- Daily maintenance calories.
- Quick targets for a mild cut, moderate cut and lean bulk.
- A simple daily protein range based on body weight.
Use clear inputs to get a more useful result.
How to use TDEE Calculator: estimate daily calories
Open the tool, fill in the fields with the data you already have and generate the result step by step. If you want to compare scenarios, change one field at a time so it is easier to understand the impact of each value.
When TDEE Calculator: estimate daily calories is useful
The goal here is simple: Estimate your daily energy expenditure and compare maintenance, deficit and lean bulk targets. It works well for quick checks, planning, study and review before you move to a final decision or document.
What to review before using the result

Frequently asked questions
What should I prepare before using the tool?
Keep the key values, labels and units ready before filling in the fields. Cleaner inputs make the final result easier to review and compare.
Can I test different scenarios on the same page?
Yes. The safest approach is to change one field at a time, compare the outputs and note which value actually changes the final answer.
Is the result ready to use without checking it?
It is better to treat it as support. Review the output once more before using it in a quote, document, spreadsheet, technical task or published page.
