Powerlifting DOTS Score Calculator
Score a powerlifting total across bodyweights with DOTS, the modern replacement for the Wilks coefficient.
How it works
coeff = 500 ÷ (a·bw⁴ + b·bw³ + c·bw² + d·bw + e) · DOTS = coeff × total
DOTS (Dots) scores a lifter’s squat-bench-deadlift total relative to bodyweight so competitors of any size can be ranked together, and it has largely replaced the older Wilks coefficient in federations like the IPF. A fourth-degree polynomial of bodyweight sets a denominator, and 500 divided by it gives a coefficient that peaks for lighter lifters and tapers for heavier ones. Multiplying by the total yields a single comparable number — higher is better.
Worked example
For a 90 kg male lifting a 500 kg total, the polynomial evaluates to about 773.3, so the coefficient is 500 ÷ 773.3 = 0.6466 and the DOTS score is 0.6466 × 500 = 323.3.
Frequently asked questions
How is DOTS different from Wilks?
Both scale totals by bodyweight, but DOTS uses a newer single formula (no separate table per sex constant beyond the coefficients) fitted to modern data and behaves better at the extremes of bodyweight. Many federations switched from Wilks to DOTS for exactly that reason.
What is a good DOTS score?
Roughly 300 is an accomplished amateur, 400 is regional/elite-amateur level, and 500+ is world-class competitive powerlifting. The scale is similar in spirit to Wilks points.
Does DOTS use kilograms or pounds?
The coefficients are defined for bodyweight and total in kilograms. Convert pounds to kilograms first (divide by 2.2046) before entering values.
