Introduction
Work out your total daily energy expenditure (TDEE) from BMR and activity level. Use The Daily Tools' TDEE Calculator for private, browser-based processing — no account or server upload required.
What is TDEE Calculator?
Total daily energy expenditure is a planning estimate. The activity multiplier is an assumption, so compare it against real-world trends and adjust cautiously over time.
Definition: TDEE Calculator estimates daily energy expenditure by applying an activity factor to a BMR estimate.
Formula
TDEE = BMR × activity multiplier (1.2 sedentary → 1.9 extra active)
Calculation steps
- The core formula: TDEE = BMR × activity multiplier (1.2 sedentary → 1.9 extra active)
- Enter your values in the fields above — units and assumptions are under your control.
- The Daily Tools computes the result instantly in your browser using JavaScript.
- Review the result panel for the primary output and supporting breakdown values.
Worked example
Example: Using the TDEE Calculator
Inputs: Enter values relevant to calories & nutrition — for example, the measurements or amounts described in the tool fields above.
- Open the TDEE Calculator and review the input fields.
- Apply the formula: TDEE = BMR × activity multiplier (1.2 sedentary → 1.9 extra active)
- Adjust inputs to compare scenarios side by side.
You receive an immediate total daily energy expenditure — useful for planning and comparison.
Use cases
- Working through a calories & nutrition question with clear inputs
- Comparing inputs in the TDEE Calculator
- Using a focused tool instead of a general spreadsheet or manual calculation
