How it's calculated
Score = coefficient × result in kg Wilks = 500 ÷ (a + bx + cx² + dx³ + ex⁴ + fx⁵) Wilks 2020 = 600 ÷ (same shape, new constants) DOTS = 500 ÷ (Ax⁴ + Bx³ + Cx² + Dx + E) IPF GL = 100 ÷ (A − B × e^(−C × x)) x = bodyweight in kg; 1 lb = 0.45359237 kg
Bodyweight scores let powerlifters of different sizes be compared on one number: a coefficient based on bodyweight is multiplied by the result. The original Wilks formula (Robert Wilks) was the standard for decades; Wilks 2020 is his update on a 600-point scale. DOTS came from the German federation (BVDK) in 2019. IPF GL points (Goodlift) are the International Powerlifting Federation's scores from 1 May 2020, with separate constants for classic and equipped powerlifting and bench press, where 100 points is the elite level for a bodyweight. The constants here are the published ones: the IPF GL document, and the Wilks, Wilks 2020 and DOTS definitions used by OpenPowerlifting. Each formula has a bodyweight range; outside it the nearest edge is used.
Your numbers, step by step
About the Wilks, DOTS and IPF GL calculator
This Wilks calculator scores a powerlifting total against bodyweight four ways at once: the original Wilks formula, Wilks 2020, DOTS and IPF GL points. Enter your sex category, bodyweight and either your total or your best squat, bench press and deadlift, in kg or lb. Pick the event too, because IPF GL points use different constants for classic and equipped lifting and for bench-only meets. The IPF GL constants are copied from the IPF's own IPF GL Coefficients document, and the coefficient is rounded to six decimal places the way that document says. Wilks, Wilks 2020 and DOTS use the definitions in OpenPowerlifting's source code. Lifters use the scores to compare themselves with people in other weight classes, and meet directors use them to rank best lifters. The steps show each coefficient and the multiplication.
How to use it
- Choose the “Units” and the “Sex (competition category)”.
- Enter your “Bodyweight” as weighed for the meet or session.
- Pick the “Event (for IPF GL points)”: classic or equipped, full powerlifting or bench press only.
- Under “Enter”, give your “Total (best squat + bench + deadlift)” or the three lifts separately.
- Read the original Wilks score, then Wilks 2020, DOTS and IPF GL points, with the coefficients in the steps.
Worked example
A man weighing 83 kg lifts 200 kg in the squat, 130 kg in the bench press and 240 kg in the deadlift, a 570 kg total in classic (raw) powerlifting. The Wilks coefficient is 0.6675, so Wilks = 0.6675 × 570 = 380.47. Wilks 2020 gives 456.94 and DOTS 384.80. The IPF GL coefficient is 0.138427, so IPF GL points = 0.138427 × 570 = 78.90.

Questions people ask
How is a Wilks score calculated?
A coefficient is worked out from bodyweight with a fifth-degree polynomial, then multiplied by the total in kilograms. Wilks = 500 ÷ (a + bx + cx² + dx³ + ex⁴ + fx⁵) × total, where x is bodyweight in kg and the constants differ for men and women.
What is the formula for IPF GL points?
IPF GL points = total × 100 ÷ (A − B × e^(−C × bodyweight)). A, B and C depend on sex and on the event: for men's classic powerlifting they are 1199.72839, 1025.18162 and 0.00921. In the IPF's own example, a 92.04 kg equipped lifter with a 1035 kg total scores 0.109039 × 1035 = 112.855 points.
What is the difference between Wilks, Wilks 2020, DOTS and IPF GL?
They all multiply your result by a bodyweight coefficient, but each was fitted to different data and uses its own scale. Wilks and DOTS centre strong totals around 500 points, Wilks 2020 around 600, and IPF GL treats 100 as the elite level for a bodyweight. Compare scores only within the same formula.
What is a good IPF GL or Wilks score?
The IPF's document says 100 GL points is set as the average elite lifter at a given bodyweight, so 100 or more is elite. For Wilks and DOTS there is no official grading, so compare yourself with lifters in your own federation, division and equipment class.
Can I enter my lifts in pounds?
Yes. Choose lb and every weight is converted with 1 lb = 0.45359237 kg before the formulas run, since all four were defined in kilograms. The working shows the converted figures. To plan the plates for an attempt, try the plate loading calculator.
What are the limits of these scores?
Each formula was fitted to a range of bodyweights, so beyond it the nearest edge is used and the score means less. Federations choose different formulas, and some change them over time, so check your federation's current rules. These are sports scores, not a measure of health or fitness.
