Type into any box. Your Wilks coefficient will be calculated automatically.
Note: This site uses the most recent version of the Wilks formula which was updated in March 2020.
The Wilks coefficient was developed by Australian powerlifter Robert Wilks as a way to compare power lifting results across various weight classes.
The higher your Wilks points, the stronger you are on a pound-for-pound basis.
It is intended to be used for the powerlifting events of bench press, squat, and deadlift. It is generally used for the combined total of all three lifts.
| points = y * | 500 |
| a + bx + cx2 + dx3 + ex4 + fx5 |
y = How much you lifted in kilograms
x = How much you you weigh in kilograms
