Age-Grade Percentage -

Data Source and Methodology

All calculations are based on the World Masters Athletics tables. Visit their site for more details. All calculations rely strictly on the formulas and data provided by this source.

The Formula Explained

The age-grade percentage is calculated using the formula:

\( \text{Age-Grade} = \left( \frac{\text{Standard Time}}{\text{Your Time}} \right) \times 100 \)

Glossary of Variables

  • Age: Your current age in years.
  • Gender: Your gender, which affects the comparative standard.
  • Race Time: Your time for a specific race distance.
  • Age-Grade Percentage: A percentage that compares your performance against the global standard for your age and gender.

How It Works: A Step-by-Step Example

Imagine a 30-year-old female runner who completes a 10K in 40 minutes. Using the standard time for her age and gender, the calculator determines her age-grade percentage, showing how she compares to the peak performance for her category.
