Formula & Mathematical Methodology: TDEE Reference Equation

TDEE = BMR × ActivityFactor
TDEE = BMR × ActivityFactor
  • weightKg: Weight Kg (kg)
  • heightCm: Height Cm (cm)
  • age: Age (years)
  • activityMultiplier: Activity Multiplier (× BMR)

Rounding: Intermediate calculations retain full IEEE-754 floating-point precision; displayed clinical and fitness metrics round to 1 or 2 decimal places.

Worked Example: Benchmark Scenario: TDEE

Compute maintenance kcal, thermic effect of food, and cutting or bulking calorie targets.

  1. Enter your current anthropometric, laboratory, or training measurements in the units indicated.
  2. Substitute the values into the reference formula: TDEE = BMR × ActivityFactor.
  3. Compare the primary output and supporting thresholds across all three custom SVG charts.
Result: Evaluates TDEE using TDEE = BMR × ActivityFactor.

Frequently Asked Questions

How is the TDEE Calculator (Total Daily Energy Expenditure) calculated?

It evaluates TDEE = BMR × ActivityFactor using your entered parameters and displays supporting clinical or training thresholds alongside three interactive SVG visualizations.

Can I compare multiple scenarios side by side?

Yes. Click the Compare button in the results panel to pin up to 3 input scenarios and inspect how changing any parameter shifts the outcome.
