WILKS Score: -
The Wilks Calculator is a powerful tool that allows you to measure your strength-to-bodyweight ratio in powerlifting. It provides a Wilks score, which enables fair comparison of lifting performances between lifters of different body weights and sexes.
The Wilks score is a coefficient-based formula used in competitive powerlifting to normalize lifter strength across different body weights. Developed by Robert Wilks, it helps answer the question:
Who is stronger pound for pound?
Rather than just looking at the total weight lifted, the Wilks score compares how much weight an athlete lifts relative to their body mass.
To calculate your Wilks score, input the following:
The calculator applies the Wilks formula to generate a score — the higher the score, the stronger you are in proportion to your weight.
The Wilks formula uses coefficients for males and females that adjust your total lifted weight. The general formula is:
Wilks Score = (Total Lift × 500) / (a + bW + cW² + dW³ + eW⁴ + fW⁵)
Where:
Note: As of 2020, the IPF has transitioned to the IPF Points system. However, Wilks is still widely used in many powerlifting competitions and gyms globally.
Whether you're a casual lifter or a competitive athlete, the Wilks score helps you benchmark your true strength.
The Wilks Calculator remains one of the most widely respected tools in powerlifting. It empowers athletes to compare their efforts on a level playing field — ensuring that strength isn’t just about the total weight, but how much weight you can lift relative to your body.
Whether you're training competitively or casually, the Wilks score offers meaningful insight into your performance and progress.
