Using the TDEE Calculator
What the calculator does
This tool is built to estimate total daily energy expenditure from body size, age, sex, and activity without making you set the formula up by hand.
It is useful for quick planning and screening, but it should support rather than replace individualized medical advice.
Formula and calculation explanation
Enter Sex, Age, Weight, Weight unit, Height, Height unit, and Activity level. Those values let the page estimate total daily energy expenditure from body size, age, sex, and activity.
The TDEE calculator starts with the Mifflin-St Jeor BMR estimate and then multiplies that resting value by the selected activity factor.
TDEE
\[TDEE = BMR \times Activity\ Multiplier\]
The activity multiplier reflects how active your average day is.
Real-world examples
- Scenario example: enter sex Female, age 29, weight 140, and weight unit Pounds (lb). That gives you a practical way to turn a real-world health or fitness question into a quick estimate.
- Comparison example: keep the baseline values the same and change weight to see how the daily calories burned responds.
Step-by-step walkthrough
- Enter Sex, Age, Weight, Weight unit, Height, Height unit, and Activity level.
- Choose the correct mode, category, or unit options before you calculate.
- Click Calculate TDEE. The calculator applies the method shown above and updates the answer instantly.
- Review the daily calories burned, then adjust one input at a time to compare scenarios cleanly.
FAQs
What does the daily calories burned result mean?
The main result shown here is daily calories burned. Adjust the inputs above to compare different scenarios and see how the answer changes.
Does this replace medical advice or diagnosis?
No. Health calculators are best used for rough planning and screening. They should support, not replace, individualized advice from a qualified professional.
Why might this calculator differ from another tool?
Different tools may use different reference formulas, rounding rules, or category cutoffs. This page uses the method explained in the formula section above.
Common mistakes
- Choosing a unit or mode that does not match the number entered in the field.
- Changing several inputs at once, which makes it harder to see which variable actually moved the result.
Edge cases
- If a required field is left blank or contains an unsupported value, the calculator will not return a useful result until the input is corrected.
Interpretation of results
The main result shown here is daily calories burned. Adjust the inputs above to compare different scenarios and see how the answer changes.
- When you compare scenarios, change one key input at a time so you can tie each output change back to a specific assumption.
