How to Use This Calculator
Enter your input values
Fill in all required input fields for the Wilks Calculator. Most fields include unit selectors so you can work in your preferred unit system — metric or imperial, whichever matches your problem.
Review your inputs
Double-check that all values are correct and that you have selected the right units for each field. Incorrect units are the most common source of calculation errors and can produce results that are off by factors of 2, 10, or more.
Read the results
The Wilks Calculator instantly computes the output and displays results with units clearly labeled. All calculations happen in your browser — no loading time and no data sent to a server.
Explore parameter sensitivity
Try adjusting individual input values to see how the output changes. This is a quick and effective way to develop intuition about how different parameters influence the result and to identify which inputs have the largest effect.
When to Use This Calculator
- •Use the Wilks Calculator when you need accurate results quickly without the risk of manual computation errors or unit conversion mistakes.
- •Use it to verify calculations made by hand or in spreadsheets — an independent check can catch errors before they lead to costly decisions.
- •Use it to explore how changing input parameters affects the output — a quick way to develop intuition and identify the most influential variables.
- •Use it when collaborating with others to ensure everyone is working from the same numbers and applying the same assumptions.
About Wilks Calculator
The Wilks score is the standard method for comparing powerlifting strength across different body weight classes. A 60 kg lifter totaling 400 kg and a 100 kg lifter totaling 500 kg cannot be directly compared without adjusting for the advantage that higher body weight provides. The Wilks coefficient applies a body-weight-dependent multiplier to the raw total, producing a score that allows fair comparison. The Wilks Calculator computes this coefficient using the official 5th-degree polynomial for your gender and body weight, then multiplies it by your total. Scores above 300 are competitive at the local level, above 400 at the national level, and above 500 at the international level. The formula has been used by the International Powerlifting Federation since the 1990s.
The Math Behind It
Formula Reference
Wilks Formula
Wilks = Total x Coefficient(bodyweight, gender)
Variables: Total = squat + bench + deadlift in kg; Coefficient is a 5th-degree polynomial based on body weight
Worked Examples
Example 1: Male lifter, 80 kg, 400 kg total
An 80 kg male lifter has a combined squat/bench/deadlift total of 400 kg.
Wilks score is approximately 283, indicating competitive local-level strength.
Common Mistakes & Tips
- !Entering the total in pounds instead of kilograms; the Wilks formula requires kg.
- !Using individual lift numbers instead of the combined total (squat + bench + deadlift).
- !Comparing Wilks scores across different federations with different equipment rules (raw vs. equipped).
