TDEE Calculator Examples
Reproduce three TDEE examples using different BMR equations, activity factors, scenario ranges, calibration, and U.S. or metric measurements.
How should you use these TDEE Calculator examples?
These examples turn the TDEE Calculator inputs into complete scenarios with stated values, calculation steps, and interpreted results. Use them to check how the calculator behaves, compare your own situation with realistic cases, and identify which inputs have the greatest effect before relying on an estimate.
These examples use the same calculation engine as the TDEE Calculator. They demonstrate different equations and assumptions; they are not calorie prescriptions.
Example 1: Mifflin-St Jeor Maintenance Estimate
A 30-year-old man is 5 feet 10 inches tall, weighs 175 pounds, enters activity factor 1.55, and keeps calibration at 0%.
| Estimated BMR | 1760 Calories/day |
|---|---|
| Estimated TDEE | 2728 Calories/day |
| Weekly equivalent | 19096 Calories/week |
| Lower factor scenario | 2376 Calories/day at 1.35 |
| Higher factor scenario | 3080 Calories/day at 1.75 |
Example 2: Revised Harris-Benedict with Metric Inputs
A 40-year-old woman is 165 cm tall, weighs 65 kg, selects revised Harris-Benedict, enters activity factor 1.40, and compares a range of 0.15.
| Estimated BMR | 1387 Calories/day |
|---|---|
| Estimated TDEE | 1941 Calories/day |
| Average per hour | 80.89 Calories/hour |
| Lower factor scenario | 1733 Calories/day at 1.25 |
| Higher factor scenario | 2149 Calories/day at 1.55 |
Example 3: Katch-McArdle with Calibration
A 35-year-old man is 180 cm tall, weighs 85 kg, enters 15% body fat, selects Katch-McArdle, uses activity factor 1.80, and applies a 5% calibration adjustment.
| Estimated BMR | 1931 Calories/day |
|---|---|
| Base TDEE before calibration | 3475 Calories/day |
| Calibrated TDEE | 3649 Calories/day |
| Calibration difference | 174 Calories/day |
| Above resting estimate | 1718 Calories/day |
Compare the Three TDEE Examples
| Scenario | BMR equation | Activity factor | Calibration | TDEE |
|---|---|---|---|---|
| Example 1 | Mifflin-St Jeor | 1.55 | 0% | 2728 Calories/day |
| Example 2 | Revised Harris-Benedict | 1.40 | 0% | 1941 Calories/day |
| Example 3 | Katch-McArdle | 1.80 | 5% | 3649 Calories/day |
The values should not be compared as if only one variable changed because each profile uses different measurements and assumptions. For a fair formula comparison, keep every input fixed and change only the BMR formula.
How to Reproduce the Results
For “How to Reproduce the Results,” the TDEE Calculator examples organizes the relevant inputs, applies the documented method, and shows a result that can be compared across scenarios. The points below identify the specific considerations and assumptions users should review before relying on the estimate.
- Open the TDEE Calculator.
- Select the U.S. or metric unit system used by the example.
- Enter age, sex term, height, weight, formula, and body fat.
- Enter the activity factor and comparison range.
- Enter the calibration percentage shown in the example.
- Calculate and compare the headline result, scenario table, charts, and derived metrics.
For the exact equations and order of operations, review the TDEE formula page.
