The formula
score = total × 500 ÷ (a + bx + cx² + dx³ + ex⁴ + fx⁵) x = bodyweight in kg
Devised by Robert Wilks, with one set of coefficients for men and another for women. Bodyweight is limited to 40–201.9 kg for men and 26.51–154.53 kg for women, as the polynomial stops giving sensible multipliers beyond these. Totals and bodyweight go in as kilograms.
What to watch out for
Add your best squat, bench press and deadlift to get the total, then enter it with your bodyweight. The formula gives lighter lifters a larger multiplier.
These are the original Wilks coefficients. A 2020 revision uses different ones, so scores from the two cannot be compared. The IPF stopped using Wilks after 2018 and other federations use their own formulas, so check which one applies to any ranking you care about.
Frequently Asked Questions
What is the Wilks score for a 90 kg man with a 600 kg total?
383.0 points, using a multiplier of 0.6384.
How much does bodyweight change the score?
The same 500 kg total scores 356.3 at 75 kg and 304.3 at 100 kg for a man.
Is Wilks or DOTS better?
Neither is settled. Wilks has been criticised for favouring some bodyweights on some lifts, and DOTS is a newer alternative. Use whichever your federation or comparison uses.
