Overview
How do you compare a 90 kg lifter's total to a 60 kg lifter's? Coefficient scores do it by weighting your total against bodyweight. This calculator uses DOTS, the modern formula that has replaced Wilks in most federations.
How it's calculated
Enter your sex, bodyweight and competition total (squat + bench + deadlift, all in kg). We plug them into the DOTS polynomial to produce a single comparable strength score — higher is stronger, pound-for-pound.
score = total × 500 / (A·bw⁴ + B·bw³ + C·bw² + D·bw + E)
How to read your result
As a rough guide, DOTS around 300 is a solid intermediate, 400 is advanced, and 500+ is elite/competitive. Because it normalises for bodyweight, you can track it as you gain or lose weight to see true strength change.
Frequently asked questions
DOTS vs Wilks — what changed?
DOTS is a newer coefficient fitted to modern data. It's now the standard in many federations because it treats today's weight classes more fairly than the original Wilks.
Does it need a competition total?
Use squat + bench + deadlift in kilograms. You can enter gym maxes too, but the score is most meaningful with a true, full-effort total.
What's a good DOTS score?
Roughly: 300 intermediate, 400 advanced, 500+ elite. Women's and men's coefficients differ so scores are comparable across sexes.
