Goal Wilks Solver

Enter a target Wilks score to see what total you need at your current bodyweight.

Weight Class Comparison

Your same total at different bodyweights produces different scores.

How to Use This Calculator

1
Select sex, age, and bodyweight — The scoring coefficients are sex- and bodyweight-specific. Age is used for McCulloch (masters adjustment). Toggle units between kg and lb.
2
Enter your competition lifts — Use your best competition total: squat + bench press + deadlift. Competition-style lifts (no hitching, no bounce).
3
Compare all four formulas — Tab 2 shows Wilks, DOTS, IPF GL, and McCulloch side by side with a radar chart and usage explanations.
4
Project competition targets — Tab 3 shows what total you need at each weight class to reach your target score, plus a curve showing how your score changes with bodyweight.

Key Formulas

Wilks = Total × 600 / (a + b×bw + c×bw² + d×bw³ + e×bw&sup4 + f×bw&sup5)
DOTS = Total × 500 / (a×bw&sup4 + b×bw³ + c×bw² + d×bw + e)
IPF GL = Σ 100 × lift / (b − a × e^(−c×bw)) per lift
McCulloch = Wilks × Age Coefficient

Key Terms

Wilks Score — Bodyweight-adjusted powerlifting total. Updated 2020 formula replaces original 1990s Wilks.
DOTS Score — Newer (2019) alternative to Wilks. Uses a different polynomial formula — generally produces similar but not identical rankings.
IPF GL Points — International Powerlifting Federation's official points system. Uses per-lift exponential curves rather than total polynomial.
McCulloch — Age-adjusted Wilks. Multiplies Wilks by an age coefficient for lifters under 23 or over 40. Used in masters divisions.
Competition Total — Sum of best squat + best bench + best deadlift in a competition (3 attempts each).
Weight Class — IPF classes: 59, 66, 74, 83, 93, 105, 120, 120+ (men); 47, 52, 57, 63, 69, 76, 84, 84+ (women).
Lift Ratio — Ideal S:B:D ratios are approximately 1.3:1:1.5. Strong benchers skew the ratio; deadlift specialists skew B:D.
Age Coefficient — McCulloch multiplier that increases Wilks for young (<23) and older (>40) lifters to account for age-related strength differences.

Real-World Examples

Intermediate Male Lifter
82.5kg BW, 180/120/220 kg total = 520kg Wilks ~320 — Advanced classification. Competitive at local meets.
Elite Female Lifter
63kg BW, 140/90/165 kg total = 395kg Wilks ~425 — World-class level. National/international competitor.
Masters Lifter (Age 55)
93kg BW, 160/100/200 kg total = 460kg McCulloch ~350 — Age-adjusted score reflects true competitive standing in masters division.

Understanding Powerlifting Scoring Formulas

Powerlifting competitions award victories within weight classes, making direct comparison between weight classes impossible using raw totals alone. A 93kg lifter totaling 800kg would beat a 74kg lifter totaling 700kg in the same competition — but which performance is "better"? Bodyweight-adjusted scores answer this question by normalizing totals for body mass.

Wilks 2020 — The Updated Standard

The original Wilks formula was developed by Robert Wilks in the 1990s. The updated 2020 formula used modern competition data from thousands of meets to produce more equitable comparisons, particularly at the extremes of the weight class spectrum. Many federations worldwide still use Wilks as their primary scoring system.

DOTS — A Community-Driven Alternative

The DOTS score (Difficulty Over Total Score) was developed in 2019 using a 4th-degree polynomial. It is argued to produce more equitable comparisons across the full weight class range. Popular in online lifting communities and some smaller federations.

IPF GL Points — The Official IPF System

Unlike Wilks and DOTS which apply a single coefficient to total, IPF GL uses per-lift exponential curves. This means two lifters with the same total but different lift distributions will receive different GL scores. The IPF updates these coefficients periodically based on competition data.

McCulloch — Age-Adjusted Fairness

The McCulloch system multiplies Wilks by an age coefficient for lifters under 23 or over 40. A 60-year-old lifter receives a 1.34x multiplier, reflecting the natural decline in strength with age. This is essential for fair best-lifter awards in masters divisions.

Frequently Asked Questions

What is the Wilks score used for?

Wilks is used to compare powerlifting performances across different bodyweight classes. It allows fair comparison between a 60kg lifter and a 100kg lifter, and is used for "Best Lifter" awards at competitions.

Which formula should I use: Wilks, DOTS, or IPF GL?

Use whichever your federation requires. IPF-affiliated competitions use GL Points. Many other federations use Wilks 2020. DOTS is popular for community comparisons. McCulloch is specifically for age-adjusted masters comparisons.

What Wilks score is considered elite?

Scores above 400 are generally considered elite amateur level. National-level competitors typically score 450-500. World-class competitors exceed 500. Grand prix and world record performances reach 600+.

Why does IPF GL give different results than Wilks?

IPF GL uses per-lift exponential curves while Wilks applies one coefficient to the total. Two lifters with the same total but different S/B/D distributions get different GL scores. This rewards balanced lifting.

How does the McCulloch age adjustment work?

McCulloch multiplies your Wilks score by an age coefficient. Ages 23-40 have a 1.0 multiplier (no adjustment). Younger lifters (14-22) get a boost (up to 1.23 at age 14). Older lifters (41+) get increasing multipliers, reaching 2.55 at age 90.

Does Wilks work for raw vs equipped lifting?

Wilks applies to both raw and equipped powerlifting. However, comparing equipped totals to raw totals is not meaningful — gear significantly increases total, especially squat and bench. Compare within the same equipment category.

Should I cut weight to improve my Wilks?

Cutting to a lower weight class only improves Wilks if the total loss from being lighter is less than the coefficient improvement. In general, competing at natural bodyweight produces better Wilks scores than aggressive cuts.

What are the ideal S:B:D lift ratios?

Typical raw powerlifting ratios: Squat ~1.3x, Bench ~1.0x, Deadlift ~1.5x (relative to bench). So if bench is 100kg, a balanced lifter squats ~130kg and deadlifts ~150kg.

How do I set a Wilks target for competition?

Determine your target based on goals (300 for first meet, 350 for state qualifier, 400 for nationals). Use the Goal Solver to find the total needed at your bodyweight, then work backwards to plan individual lifts.

Why did the IPF switch from Wilks to GL Points?

The IPF wanted a scoring system that accounts for individual lift performance rather than just total. GL Points use per-lift curves, which better reflect the difficulty of each lift at different bodyweights and reward balanced lifting.

Can I use these formulas for single-lift competitions?

Wilks and DOTS were calibrated for competition totals. For single lifts, IPF GL is more appropriate since it already calculates per-lift scores. You can enter only one lift and leave the others at zero to see single-lift GL points.

What is the highest Wilks score ever recorded?

Using the 2020 formula, the highest raw powerlifting scores are in the 650-700+ range for elite male lifters. Female world records translate to 600-650 range. Equipped records would be higher due to gear assistance.
