What the Wilks Score Actually Measures
The Wilks score answers a question raw totals cannot: who is strongest relative to their size? It multiplies your competition total by a coefficient derived from your bodyweight, so lighter and heavier lifters land on one comparable scale. Elite raw lifters score around 400 and up; the best open competitors climb past 500. Enter your bodyweight, your total, and your sex, and you get both the score and a rating band showing where you sit.
A Worked Example
Take two lifters who both total 500 kg. The 80 kg lifter earns a larger coefficient than the 120 kg lifter, so the lighter athlete posts the higher Wilks score even though the barbell weight is identical. That is the whole point — the formula credits the smaller lifter for moving the same load with less body mass behind it. Swap in your own numbers and you can watch the coefficient fall as bodyweight rises, which is why a lean bulk that adds total but also adds weight doesn't always move your Wilks.
Where Wilks Fits Among Modern Formulas
Wilks was the sport's default normalizer for decades, but it isn't the only one anymore. Wilks-2 recalibrated the same polynomial to newer data in 2020, DOTS offers an alternative curve some prefer at the bodyweight extremes, and the IPF now uses GL points for its own awards. This tool computes the classic Wilks so you can line up against historical totals and the gym-board numbers most lifters still quote — just know that scores from different systems aren't directly comparable.

General strength level guidelines for men and women
| Level | Men | Women |
|---|---|---|
| Beginner | Under 200 | Under 150 |
| Novice | 200–300 | 150–250 |
| Intermediate | 300–400 | 250–350 |
| Advanced | 400–450 | 350–400 |
| Elite | 450–500 | 400–450 |
| World Class | 500+ | 450+ |
How to Use This Calculator
- Enter Your Bodyweight: Use your weigh-in bodyweight, not a round number — the coefficient is sensitive to it. Pick lbs or kg with the toggle; the calculator converts for you.
- Enter Your Total: Add your best squat, bench, and deadlift for a full powerlifting total, or enter a single lift if you only want to score one movement.
- Select Your Sex: Men and women use different coefficients, so this choice changes the result. Pick the one that matches the formula constants you want applied.
- Calculate: Run the numbers and the Wilks score appears instantly, computed in your browser.
- Read the Score and Rating: Compare the score against another lifter's, log it next to your bodyweight, or check the rating band to see whether you're intermediate, advanced, or elite.
How It Works
Raw totals reward heavy lifters — a 140 kg lifter almost always out-totals a 60 kg lifter. The Wilks score removes that advantage by scaling every total against a bodyweight curve, so a 500 kg total means something different for each lifter and can be ranked head to head.
The basic rule:
- Enter your bodyweight, your competition total (squat + bench + deadlift), and your sex.
- The calculator plugs your bodyweight in kilograms into a 5th-degree polynomial to produce a coefficient — men and women use different constants.
- Your total is multiplied by that coefficient: Wilks = total (kg) × coefficient. Lighter lifters get a larger coefficient, which is how they stay competitive with heavier lifters.
- The coefficient peaks for very light lifters and shrinks as bodyweight climbs, flattening the raw advantage of extra mass.
- Enter a single lift instead of a full total if you only want to compare one movement.
For years the Wilks coefficient was the standard for best-lifter awards worldwide. Federations have since moved toward Wilks-2 (a 2020 recalibration) and IPF GL points, but the original Wilks remains the number most lifters know, and it is still the easiest way to compare an old total against a new one on the same scale.
Tips & Considerations
- Use your actual weigh-in bodyweight. Rounding 82.4 kg to 80 kg nudges the coefficient and inflates your score.
- Match units across both inputs — the toggle handles the conversion, but a total in kg against a bodyweight in lbs will be nonsense.
- Log your Wilks alongside your bodyweight each time. If your total rose but your Wilks didn't, the extra bodyweight ate the gain.
- To compare against a friend, make sure you're both using the classic Wilks here rather than mixing in a DOTS or IPF GL number.
- A single-lift Wilks only compares to the same lift — don't stack a bench-only score against someone's full total.
Frequently Asked Questions
What is a good Wilks score?
As a rough map for men: a beginner clears 200-300, an intermediate lifter lands around 300-400, 400-450 is advanced, and 450+ is elite. For women, subtract roughly 50 points at each tier — 250-350 is a solid intermediate range and 400+ is elite. A raw total scoring 400+ generally puts a man in national-competitor territory; the very best open lifters push past 500.
Why normalize a total by bodyweight at all?
Absolute strength scales with body mass, so a raw total leaderboard is really a bodyweight leaderboard — the heaviest lifters win by default. Normalizing lets a 66 kg lifter and a 120 kg lifter compare pound-for-pound. It is also the only fair way to hand out a single best-lifter award at a meet where competitors span 60 kg to 140 kg.
What is the exact Wilks formula?
Coefficient = 500 ÷ (a + b·x + c·x² + d·x³ + e·x⁴ + f·x⁵), where x is bodyweight in kilograms and a through f are constants that differ for men and women. Your score is total (kg) × coefficient. Because bodyweight sits in the denominator, a lighter lifter gets a bigger multiplier.
Wilks vs IPF GL points — what's the difference?
Both normalize by bodyweight, but they were fit to different data. The original Wilks was calibrated in the mid-1990s. Wilks-2 (2020) refit the same polynomial to modern results, and IPF GL points use a different equation form tuned to IPF drug-tested records. GL points now decide IPF best-lifter awards, while classic Wilks lingers on gym boards and in older records. Numbers from different systems are not interchangeable.
Does the Wilks score work for a single lift?
Yes — enter one lift instead of the full total and you get a Wilks number for that movement, useful for ranking bench-only meets or comparing your deadlift to a training partner's. Just keep it consistent: a single-lift Wilks only compares to other single-lift Wilks of the same movement, never to a full-total score.
What bodyweight range is the Wilks formula valid for?
It is fit for roughly 40-205 kg (88-452 lbs) for men and 40-150 kg (88-331 lbs) for women. Inside that band it behaves well; at the extreme light and extreme heavy ends the curve is thinner on data, which is one reason DOTS and Wilks-2 were introduced.
