Calculate your Wilks score based on your total and bodyweight
Results
The Wilks Calculator is one of the most recognizable tools in the sport of powerlifting. It allows athletes, coaches, and meet directors to compare lifters across different body weights using a mathematical formula called the Wilks Coefficient. While newer formulas like DOTS and IPF GL have taken over in some federations, Wilks remains a respected and widely used benchmark in many gyms, amateur meets, and national-level federations.
This Wilks Calculator is built for simplicity and precision. It only requires two inputs — bodyweight and total lifted — and instantly outputs your Wilks score in a sleek, responsive popup styled with the same clean orange theme as our other powerlifting tools.
🧠 What Is the Wilks Formula?
The Wilks formula was introduced by Robert Wilks, an Australian powerlifting official, and became the official scoring method of the International Powerlifting Federation (IPF) for many years prior to the adoption of the GL system in 2020. Its goal is to make strength performance comparable across athletes of different body sizes.
It does this by assigning a coefficient to each lifter based on their bodyweight and gender. The total lifted (in kg) is then multiplied by this coefficient to yield the Wilks Score — a number that reflects your relative strength.
📐 Wilks Formula (Updated 2020 Version)
The current calculator uses the 2020 revision of the Wilks formula, which is more accurate and mathematically balanced than earlier versions. The formula is as follows: Wilks Score=500×Total Lifteda+b⋅BW+c⋅BW2+d⋅BW3+e⋅BW4+f⋅BW5\text{Wilks Score} = \frac{500 \times \text{Total Lifted}}{a + b \cdot BW + c \cdot BW^2 + d \cdot BW^3 + e \cdot BW^4 + f \cdot BW^5}Wilks Score=a+b⋅BW+c⋅BW2+d⋅BW3+e⋅BW4+f⋅BW5500×Total Lifted
Where:
BW= bodyweight in kilogramsTotal Lifted= best squat + bench + deadlift- The coefficients
a–fdepend on gender.
🔸 Male Coefficients:
- a = -216.0475144
- b = 16.2606339
- c = -0.002388645
- d = -0.00113732
- e = 0.00000701863
- f = -0.00000001291
🔸 Female Coefficients:
- a = 594.31747775582
- b = -27.23842536447
- c = 0.82112226871
- d = -0.00930733913
- e = 0.00004731582
- f = -0.00000009054
These constants allow the formula to reflect the reality that heavier lifters can lift more weight, but not necessarily at the same relative strength as lighter lifters.

Whether you're testing your strength at the gym or comparing yourself to lifters in your federation, this calculator offers a fast, clean solution to finding your Wilks score.
🏁 Who Uses Wilks?
Despite the rise of DOTS and GL formulas, Wilks is still used by:
- National and regional federations like CAPO, GPC, and GPA
- Gym competitions and unsanctioned meets
- Training apps and spreadsheets that haven’t migrated to new formulas
- Lifters wanting legacy comparisons with older records or stats
Many powerlifting programs also use Wilks scores to benchmark lifters or categorize them for training intensity levels.
📊 Why Use the Wilks Calculator?
- 🟧 It’s simple and doesn’t require rep counts or age categories.
- 🟧 It’s versatile and can be used for raw or equipped totals.
- 🟧 It allows for historical comparisons, especially with older lifters or competitions.
- 🟧 It’s ideal for group ranking, such as intra-gym leaderboards or team scoring.
This makes Wilks a valuable tool not just for competitors, but also for recreational lifters who want a concrete way to measure their strength against others.
📈 Sample Use Case
Suppose you're a female lifter weighing 63 kg and your powerlifting total is 400 kg. By inputting those numbers into the Wilks Calculator, your score might come out to:
- Wilks Score: 359.41
You can then use this to compare your performance to lifters in other weight classes or track your progress over time as your total increases or your bodyweight changes.
🔍 Interpreting Your Wilks Score
While there is no universal standard, here’s a rough guideline:
| Wilks Score | Strength Level |
|---|---|
| 250–300 | Novice |
| 300–350 | Intermediate |
| 350–400 | Advanced |
| 400–450 | Competitive |
| 450+ | Elite / Pro Level |
