Running is one of the most popular and accessible sports around the world. But as we age, our performance naturally changes. That’s where the Age-Graded Calculator comes in. It helps runners of all ages compare their performance fairly. Whether you're a seasoned master runner, a weekend warrior, or just curious about how your running time compares to others, this tool gives you valuable insights.
Our Free Age-Graded Calculator is designed to be user-friendly, accurate, and quick. It uses globally accepted formulas to determine how your performance stacks up against world standards, adjusted for your age and gender.
An Age-Graded Calculator is a tool that adjusts your race performance to a standard that considers your age and gender. It shows how your time compares to the world record for someone of your age and gender, or vice versa.
For example, a 50-year-old woman running a 5K in 25 minutes can see how that compares to a 30-year-old man running a 5K in 20 minutes. This method brings fairness and accuracy when comparing performances across different age groups.
This tool is often used by runners in masters events, parkrun results, and club competitions to see how well they are performing as they age.
The age-graded percentage is calculated using a standard formula based on tables provided by World Masters Athletics. These tables define the best possible performances by age and gender.
Age Graded Time Formula:
Age-Graded Time = (World Record Time for Age & Gender) × (Your Time ÷ Age Standard Time)
Age Graded Percentage Formula:
Age-Graded % = (Age Standard Time ÷ Your Time) × 100
The calculator shows both your age-graded time and performance percentage so you can better understand your running level.
Using the calculator is very simple. You don’t need to download anything. Just visit our online tool and enter:
