DOTS Calculator

What is a DOTS score?

DOTS is a points formula for powerlifting. It divides your total (best squat + bench press + deadlift) by a curve based on bodyweight, so a lighter and a heavier lifter can be compared fairly. A higher score means a stronger total for your size.

The DOTS formula

DOTS = total × 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴), where x is bodyweight in kilograms and the total is in kilograms.

The curves are fitted for bodyweights of 40–210 kg for men and 40–150 kg for women. Outside that range the calculator uses the nearest limit and tells you, because the curve stops making sense beyond it. Pound inputs are converted to kilograms (1 kg = 2.20462 lb) before scoring.

Example DOTS scores

Using your score

• Use tested lifts. DOTS is meant for real competition-style singles. You can plug in estimated maxes from the 1RM calculator, but the result is then an estimate too.
• Equipment matters. Raw and equipped totals are not comparable, even with the same score formula.
• Federations differ. Some federations rank lifters with other formulas, such as IPF GL points or Wilks. Check which one your meet uses — scores from different formulas are not interchangeable.
• Track yourself. The most useful comparison is your own score over time, especially if your bodyweight changes.
