World Masters Athletics Age-Grade Calculator (2015 base)

To use the calculator, select an event (or enter the distance), enter your details and result, then press Age-grade to lookup the WMA factor. This factor is used to calculate an age-graded result, which can be compared between athletes of different ages.

Also shown are the Open and age-graded standards set by WMA. Your age-performance as a percentage of the Age standard is calculated from these. This performance can be compared between different events.

Pressing Result will calculate your result for a given age-performance – eg, use your age-performance in one event to predict a different event or the same event at a different age.

The Age-Grade Calculator’s underlying age-grade tables can be applied to five-year age groups or individual ages from 8 to 100. The only official use of the Age-Graded Tables by WMA is in scoring multi-event competitions. But, the Age-Graded Tables have been incorporated into track meet management software by Hy-Tek and others. They are used to determine age-graded winners in many other competitions, especially road runs.
