Calculate age-graded performance from race time, age, and sex. Compare results across ages using WMA-style age-grading factors.
This age-graded calculator evaluates your race result against age-group standards. Enter distance, finish time, age, and sex — for example, a 53-year-old male running 23:10 for 5K — to see your age-graded time and performance percentage.
The calculation uses World Masters Athletics-style age-grading factors for road racing. Older runners receive credit through a factor that adjusts their time to an age-graded equivalent, which can be compared across ages and distances.
Performance levels are approximate guides: 90%+ is world class for the age group, 80–89% national, 70–79% regional, and 60–69% local. Most recreational runners score below 60%. Use age-grading to compare your own progress year over year rather than against open-class elites.
