DOTS and Wilks calculator.
Score your total for your bodyweight, so you can compare your own lifts as your weight changes.
How it works
Your total, scaled for bodyweight.
Heavier lifters can lift more, but not in a straight line. Both formulas divide 500 by a curve fitted to bodyweight, then multiply by your total.
DOTS was made by Tim Konertz for the German powerlifting federation (BVDK) and is used by many federations. Men's curve uses a = −0.0000010930, b = 0.0007391293, c = −0.1918759221, d = 24.0900756, e = −307.75076 (bodyweight held between 40 and 210 kg). Women's: a = −0.0000010706, b = 0.0005158568, c = −0.1126655495, d = 13.6175032, e = −57.96288 (40 to 150 kg).
Wilks was the International Powerlifting Federation's formula until 2019; this is the original version. The IPF now uses its own IPF GL points.
Limits
- A formula score, not a ranking. It doesn't say how you compare with anyone.
- Built from competition totals in kg. Single lifts work, but the curves were fitted to totals.
- Outside the bodyweight bounds the score uses the nearest bound.
