How to use it
- Enter your bodyweight and choose kilograms or pounds.
- Choose your sex, equipment and the lift, then enter the weight lifted in the same unit.
- Read the Wilks2 points and the IPF GL points; the table shows all three formulas together.
- Compare your points with those of other lifters of any bodyweight; higher is better.
How the points are calculated
Wilks scores divide the lift by a polynomial of bodyweight, so a heavier lifter's lift is scaled down. The original 1994 formula uses 500 in the numerator; the 2020 Wilks2 formula uses 600 and new coefficients that rebalance men's and women's scores and the extreme bodyweight classes.
IPF GL points use a curve fitted to elite results in each bodyweight class: 100 points is the average elite level for that bodyweight. The IPF publishes separate constants for classic and equipped lifting and for the total and the bench press.
Wilks (1994): points = lift × 500 / P(x)
Wilks2 (2020): points = lift × 600 / P(x)
P(x) = a + b·x + c·x² + d·x³ + e·x⁴ + f·x⁵ (x = bodyweight in kg)
IPF GL: points = lift × 100 / (A − B·e^(−C·x))- Wilks2 coefficients: men a 47.46178854, b 8.472061379, c 0.07369410346, d −0.001395833811, e 7.07665973070743e-6, f −1.20804336482315e-8; women a −125.4255398, b 13.71219419, c −0.03307250631, d −0.001050400051, e 9.38773881462799e-6, f −2.3334613884954e-8.
- IPF GL constants A, B and C are those of Table 1 of the 2020 IPF GL document. The coefficient is rounded to six decimals, as the document asks.
What this calculator does not include
DOTS is not included: its coefficients could not be confirmed from a primary source for this tool. Scores from different formulas are not the same number, and a federation's official rankings use the formula that federation chose.
The formulas compare relative strength only. They say nothing about technique, age class or a lifter's record; use the rules of the competition you enter.
Worked example: 80 kg man, 500 kg classic total
The 1994 polynomial at 80 kg gives 732.39, so Wilks (1994) is 500 × 500 / 732.39 = 341.35 points; the 2020 polynomial gives 732.48, so Wilks2 (2020) is 500 × 600 / 732.48 = 409.57 points.
The IPF GL coefficient for a classic man at 80 kg is 100 / (1199.72839 − 1025.18162 × e^(−0.00921 × 80)) = 0.141037, so the total gives 500 × 0.141037 = 70.52 points.
| Formula | Points |
|---|---|
| Wilks (original, 1994) | 341.35 |
| Wilks2 (2020) | 409.57 |
| IPF GL (2020 coefficients) | 70.52 |
Frequently asked questions
Which score should I use?
Use the score of the federation whose rules you lift under. Wilks2 is the newer general formula, and IPF GL is the score the IPF uses for its own ranking, with the coefficients in its 2020 document.
Why are the Wilks and GL numbers so different?
They are on different scales. Wilks2 is around 400 for the example above and IPF GL is around 70, because the IPF GL points are normalised to 100 for an elite lifter of each bodyweight.
Can I score a single lift?
Yes for Wilks: the same formula scales any lift. IPF GL covers only the total and the bench press, so the calculator shows no GL points for a squat or deadlift.
Why is DOTS not in this tool?
The DOTS coefficients could not be confirmed from a primary source, so they are not shown. Relative strength scores from other federations are not the same as these.
Does the bodyweight have to be exact?
Enter your bodyweight on the day of the lift, because every formula uses it directly: the same lift at a different bodyweight gives a different score.
