Wilks Calculator
The Wilks score levels the playing field in powerlifting by adjusting your total lifted for body weight, so a lighter and a heavier lifter can be compared fairly. Enter your sex, body weight and total lifted (squat + bench + deadlift, or any single lift) to get your Wilks coefficient and score, plus a rough strength level. It is the most widely used relative-strength formula in the sport.
How to use the Wilks calculator
Pick your sex, enter your body weight and your total lifted — squat plus bench plus deadlift, or any single lift — then press calculate. You can toggle between kg and lb before you run it, and the tool converts for you. Your Wilks score appears instantly, alongside the Wilks coefficient and a rough strength level, with no sign-up and nothing to install. Change any field and recalculate to compare lifts or bodyweights side by side.
How to read your result
A higher Wilks score means you are stronger pound-for-pound, whatever you weigh. As a rough guide, around 300 is a solid, well-trained lifter, near 400 is very strong and competitive at many local meets, and 500 or above is elite territory. The whole point is fairness: a 60 kg and a 110 kg lifter can post very different totals yet land at a similar Wilks, so the score lets you compare them on equal footing.
The science behind the score
The Wilks coefficient is a fifth-order polynomial function of body weight, with separate constants for men and women, tuned so that heavier lifters are scaled down to offset their natural leverage and mass advantage. The calculator evaluates that polynomial for your bodyweight, turns it into a coefficient, then multiplies it by your total lifted to normalize the result. Two athletes at different bodyweights are effectively placed on one curve, which is why the same total produces different scores at 70 kg and 100 kg.
Limits and practical tips
Wilks has largely been superseded by newer formulas such as IPF GL points and DOTS, and it can be unkind at the extreme ends of the bodyweight range while ignoring age entirely. Treat it as a relative-strength comparison, not a verdict on your worth as a lifter. For a broader picture, pair it with CaloNote’s Relative Strength calculator, and use the One-Rep-Max calculator to estimate a lift you have not maxed out. The CaloNote app then helps you track training and nutrition over time.
Frequently Asked Questions
- What is a Wilks score?
- The Wilks score is a coefficient that adjusts a powerlifter's total lifted weight for body weight, letting lifters of different sizes and sexes be compared fairly. It's widely used to rank performances and crown best-lifter awards at competitions.
- How do I calculate my Wilks score?
- Your total (squat, bench and deadlift) is multiplied by a Wilks coefficient derived from your body weight and sex. Enter your total and body weight here and the calculator applies the formula to return your score automatically.
- What is a good Wilks score?
- As a rough guide, scores around 300 reflect a solid intermediate lifter, 400 is advanced, and 500 or more approaches elite territory, with top competitors exceeding 500. Because the scale differs slightly by sex, compare within your own category.
