Enter your bodyweight and your best squat, bench press and deadlift, or just your total. The scores adjust for bodyweight so lifters of different sizes can be compared; a higher score means a stronger lift for your weight.
| Score | Coefficient | Rough level |
|---|
All three formulas divide your total by a bodyweight-dependent curve, so a 600 kg total means more for a 74 kg lifter than for a 120 kg one.
DOTS (2019, used by many federations including USAPL and OpenPowerlifting rankings): score = total × 500 ÷ (a + b·BW + c·BW² + d·BW³ + e·BW⁴), with bodyweight limited to 40–210 kg for men and 40–150 kg for women.
IPF GL (Goodlift) points (IPF, 2020): score = total × 100 ÷ (A − B·e−C·BW), with separate constants for men and women, classic and equipped, and full powerlifting or bench only.
Wilks (original, used until 2020): score = total × 500 ÷ a fifth-degree polynomial of bodyweight. Still widely quoted, although it tends to favour middle weight classes.
Example: an 83 kg man totalling 570 kg (200 / 130 / 240) scores about 385 DOTS, 79 IPF GL and 380 Wilks.
As a rough guide for drug-free lifters: under 250 is a beginner, 300–350 intermediate, 350–400 advanced, 400–450 national level, and above about 500 elite and world-class.
They’re all ways of comparing lifters of different bodyweights. Wilks is the oldest; DOTS was designed to be fairer across all weight classes; IPF GL is the formula the International Powerlifting Federation uses for its best-lifter awards, with separate versions for classic and equipped lifting and for bench press.
Classic (raw) means lifting with only a belt, wrist wraps and knee sleeves. Equipped means supportive squat suits, bench shirts and knee wraps. The choice only changes the IPF GL score, which has separate constants for each.
Yes. Switch to lb and enter your bodyweight and lifts in pounds; they’re converted to kilograms for the formulas.
An updated Wilks formula released in 2020 with a different scale. It’s rarely used now that most federations have moved to DOTS or IPF GL, so the original Wilks is shown here for comparison with older results.
