The **Wilks Calculator** by **Dr. Robert Wilks** is widely used in the **powerlifting community** to evaluate an athlete’s **strength performance** relative to their **body weight**.

The **wilks score calculator** takes an athlete’s **total lifted weight** (the sum of their best lifts in the squat, bench press, and deadlift) and their body weight, and then applies the **Wilks formula** to generate a **Wilks score**.

An athlete weighs

175 poundsand has a total lifted weight of1,500 pounds. Using the Wilks Calculator, we can determine their Wilks score:

**Wilks score** = 500.0 *(1.0890873 + 0.0124764* 175 - 0.0006609 *175 ^ 2 + 0.0000945* 175 ^ 3 - 0.0000005 *175 ^ 4) = *400.35*

This means that the lifter’s strength is equivalent to a **400.35-pound lifter** in the **175-pound weight class**, which is a very **impressive performance**.

Formula Developed by

Dr. Robert Wilks, the Wilks formula provides astandardizedway to compare lifters of different body weights by adjusting their total lifted weight. This allows for a morefairandequitable assessmentof strength across weight classes, making it avaluable metricfor powerlifting competitions and training.

## Wilks Formula

The **Wilks formula** is as follows:

**Wilks score** = 500.0 *(a + b* bodyweight + c *bodyweight^2 + d* bodyweight^3 + e * bodyweight^4)

Where:

a= 1.0518033b= 0.0122500c= -0.0000638d= 0.0000053e= -0.0000000

**Let’s break down the formula with an example:**

Suppose we have an athlete who weighs **175 pounds** and has a total lifted weight of **1,500 pounds**.

We can plug these values into the **Wilks formula** to calculate their **Wilks score**:

**Wilks score** = 500.0 *(1.0518033 + 0.0122500* 175 - 0.0000638 *175^2 + 0.0000053* 175^3 - 0.0000000 *175^4)*

**Wilks score** = 500.0 (1.0890873 + 0.0124764 *175 - 0.0006609* 175^2 + 0.0000945 *175^3 - 0.0000005* 175^4)

**Wilks score** = 500.0 *0.8007*

**Wilks score** = *400.35

With a body weight of **175 pounds** and a total lifted weight of **1,500 pounds**, the athlete’s **Wilks score** is **400.35**.

## How to calculate Wilks powerlifting?

Calculating a **Wilks score** for powerlifting requires a few simple steps:

**Determine the Athlete’s Body Weight**: The first step is to accurately measure the athlete’s body weight, typically in **pounds** or **kilograms**.

**Obtain the Athlete’s Total Lifted Weight**: This is the sum of the athlete’s **best lifts** in the three powerlifting events: **squat**, **bench press**, and **deadlift**.

**Apply the Wilks Formula**: Using the athlete’s body weight and total lifted weight

Put the values into the **Wilks formula**:

**Wilks score** = 500.0 *(a + b* bodyweight + c *bodyweight^2 + d* bodyweight^3 + e * bodyweight^4)
Where:
**a** = 1.0518033**b** = 0.0122500**c** = -0.0000638**d** = 0.0000053**e** = -0.0000000This will give you the athlete's **Wilks score**.

**Interpret the Wilks Score**: The **Wilks score** represents the athlete’s strength relative to their body weight. A **higher Wilks score** indicates **greater relative strength**.

Let’s say an athlete weighs **165 pounds** and has a total lifted weight of **1,450 pounds**. To calculate their **Wilks score**:

Body weight: **165 pounds**

Total lifted weight: **1,450 pounds**

**Wilks formula**:

**Wilks score** = 500.0 *(1.0518033 + 0.0122500* 165 - 0.0000638 *165^2 + 0.0000053* 165^3 - 0.0000000 *165^4)
***Wilks score** = 500.0 0.7945
**Wilks score** = **397.25**

The athlete’s **Wilks score** is **397.25**, which indicates their strength is equivalent to a **397.25-pound lifter** in the **165-pound weight class**.

## What is a good Wilks score?

**Elite/World-Class Level**: A**Wilks score**of**500 or higher**is considered**elite-level performance**, achieved by only the strongest powerlifters in the world.**National/International Level**: A**Wilks score**of**400-500**is generally considered a**high-level performance**, often seen in national or international competition.**Competitive Level**: A**Wilks score**of**350-400**is a solid,**competitive-level performance**, where the athlete can be competitive in regional or national powerlifting events.**Intermediate Level**: A**Wilks score**of**300-350**is a good performance for an**intermediate-level powerlifter**, indicating solid strength development.**Novice Level**: A**Wilks score**of**250-300**is a respectable starting point for a**novice powerlifter**, showing promise and potential for future growth.

An athlete who weighs **185 pounds** and has a total lifted weight of **1,600 pounds**. Using the **Wilks formula**, we can calculate their **Wilks score**:

**Wilks score** = 500.0 *(1.0518033 + 0.0122500* 185 - 0.0000638 *185^2 + 0.0000053* 185^3 - 0.0000000 *185^4)*

**Wilks score** = 500.0 0.7901

**Wilks score** = **395.05**

With a **Wilks score** of **395.05**, this athlete would be considered a **competitive-level powerlifter**, with the potential to perform well in regional or national-level competitions.
