DOTS Calculator (Powerlifting)

Enter your body weight and total (or each lift) to compute your DOTS score. DOTS normalizes strength across body weights using gender-specific polynomial coefficients.

Calculate Your DOTS

How DOTS Works

Formula (kg)

Coefficient (male): 500 / (−1.093e−6·w⁴ + 7.391293e−4·w³ − 0.1918759221·w² + 24.0900756·w − 307.75076)
Coefficient (female): 500 / (−1.0706e−6·w⁴ + 5.158568e−4·w³ − 0.1126655495·w² + 13.6175032·w − 57.96288)
DOTS: coefficient × total(kg)

Steps:

  1. 1
    Enter body weight and lifts
    Use kg or lbs (auto-converted to kg).
  2. 2
    Compute coefficient
    Use the gender-specific polynomial with body weight (kg).
  3. 3
    Multiply by total
    DOTS = coefficient × total(kg).

Important Notes

Weight Classes

DOTS compares lifters across body weights; federations still award by class. Check your federation rules.

Raw vs Equipped

DOTS itself doesn’t distinguish equipment; events usually separate divisions (Raw/Raw-With-Wraps/Equipped).

Cutting Weight

Extreme cuts may lower performance; a small net gain in DOTS isn’t guaranteed.

Model Limits

Polynomial fit is most reliable in typical competitive ranges; accuracy drops at extremes.

Example Cases

Case 1: Male, 90kg BW, 610kg total

Coefficient: 0.647
Total: 610 kg
DOTS: 394.4
Computed with the same formula used by the calculator.

Case 2: Female, 63kg BW, 420kg total

Coefficient: 1.076
Total: 420 kg
DOTS: 451.7
Computed with the same formula used by the calculator.

FAQ

What is the DOTS score?
DOTS is a relative strength score used in powerlifting. It multiplies your powerlifting total (kg) by a coefficient derived from your body weight using a gender-specific polynomial, so lifters across different body weights can be compared fairly.
Do I need to enter all three lifts?
No. If you provide a Total, the calculator uses it directly. Otherwise it sums squat, bench press, and deadlift.
Should I use kg or lbs?
Use either. The calculator converts values to kilograms internally before applying the DOTS coefficient.
Is DOTS the same as Wilks or IPF GL?
They are different scoring systems. Many federations today use DOTS or IPF GL instead of the older Wilks. Your federation may specify which to use.
How accurate is DOTS?
DOTS is fitted on a large dataset of results. Like any model, it is most reliable within typical competitive bodyweight ranges and can be less accurate at the extremes.
