How strong are you,
pound for pound?
DOTS turns your squat, bench, and deadlift total into a single bodyweight-adjusted score, so a 60 kg lifter and a 120 kg lifter can be compared fairly. It's the modern formula that replaced Wilks in Open Powerlifting.

DOTS adjusts your powerlifting total for bodyweight with a 5th-order polynomial, replacing the older Wilks formula as the fairer modern standard used by Open Powerlifting.
The science
What DOTS measures
and why it beats Wilks
DOTS answers a question a raw total cannot: who is actually stronger when two lifters weigh different amounts? A 600 kg total is far more impressive at 75 kg bodyweight than at 140 kg. DOTS corrects for that by dividing your total by a bodyweight-based factor, producing one number you can compare across the entire field.
The formula:
- DOTS = total (kg) × 500 ÷ (a + b·BW + c·BW² + d·BW³ + e·BW⁴)
- BW = bodyweight in kg; a–e are sex-specific coefficients
The denominator is a 5th-order polynomial (a quartic in bodyweight) fit to a large set of real competition results. That fit is the whole point: it lets a single continuous curve replace the old per-class lookup tables and smooths out the unfair jumps that plagued earlier systems.
For years the standard was the Wilks coefficient, introduced by Robert Wilks in the 1990s. Wilks worked, but as the data grew, statisticians found it systematically over- or under-rewarded certain bodyweight classes — lighter and heavier lifters in particular. DOTS (Dynamic Objective Team Scoring) was refit to newer, larger data and adopted by Open Powerliftingand many federations as the fairer, more modern replacement. If you've seen an older “Wilks score,” DOTS is the number that quietly took its place.
Worked examples
Two real calculations, step by step
Scenario 1
100 kg male, 600 kg total
BW = 100 kg, total = 600 kg
Denominator = a + b·100 + c·100² + d·100³ + e·100⁴
DOTS = 600 × 500 ÷ denominator
= 369.3 — advanced
Scenario 2
60 kg female, 300 kg total
BW = 60 kg, total = 300 kg
Uses the women's coefficients
DOTS = 300 × 500 ÷ denominator
= 332.6 — advanced
(the men's formula gives only 253.2 for the same numbers — that's the sex adjustment at work)
FAQ
Common questions
What is a good DOTS score?
As a rough guide, a DOTS score below 200 is beginner level, 200–300 is intermediate, 300–400 is advanced, 400–500 is elite, and 500+ is world-class. Most competitive raw lifters fall somewhere in the 300–450 range, and a DOTS over 500 typically means a podium at a national or international meet.
DOTS vs Wilks — what's the difference?
Both convert a powerlifting total into a single bodyweight-adjusted score so lifters of different sizes can be compared. Wilks came first, but its coefficients were criticized for disadvantaging certain bodyweight classes — especially lighter and heavier lifters. DOTS was fit to a larger, more recent dataset using a 5th-order polynomial and has replaced Wilks as the default scoring system in Open Powerlifting and many federations.
Is DOTS the same for men and women?
No. DOTS uses separate polynomial coefficients for men and women to account for differences in average strength relative to bodyweight. For the same total and bodyweight, the women's formula returns a higher DOTS score, which keeps the rankings fair across sexes.
How is DOTS calculated?
DOTS = total lifted (kg) × 500 ÷ (a + b·BW + c·BW² + d·BW³ + e·BW⁴), where BW is bodyweight in kilograms and a–e are sex-specific coefficients. The denominator is a 5th-order (quartic) polynomial fit to real competition data, so the formula needs no separate lookup table — just your total and bodyweight.
Should I use kg or lb?
Either works — this calculator converts pounds to kilograms (×0.453592) before applying the formula, because DOTS is defined in metric. Just make sure your bodyweight and your total use the same unit.
