**The Wilks Calculator is a tool used in the sport of powerlifting to compare the performances of athletes across different weight classes. **

It is named after its creator, **Robert Wilks**, who developed the formula in 1976. The Wilks Calculator assigns a **“coefficient”** to each lifter based on their **bodyweight**, which is then multiplied by their **total lift** (the sum of their best squat, bench press, and deadlift) to calculate a **“Wilks score.”**

## Wilks Calculator

Calculate your Wilks score for powerlifting.

Lifter | Weight Class | Total Lift (kg) | Bodyweight (kg) | Coefficient | Wilks Score |
---|---|---|---|---|---|

John | 93 kg | 700 | 92 | 0.6684 | 468 |

Sarah | 63 kg | 450 | 62 | 0.9196 | 414 |

Michael | 120+ kg | 900 | 145 | 0.4239 | 381 |

Emily | 72 kg | 525 | 70 | 0.8292 | 435 |

## Wilks Calculation Formula

The Wilks calculation formula is as follows:

**Wilks Score = Total Lift (kg) x Coefficient**

The coefficient is calculated using the following formula:

**Coefficient = a + b x bodyweight (kg) + c x bodyweight (kg)^2 + d x bodyweight (kg)^3 + e x bodyweight (kg)^4 + f x bodyweight (kg)^5**

The constants (a, b, c, d, e, f) are different for **men** and **women**, reflecting the physiological differences in strength between the sexes.

For men, the constants are:

- a = -27.23542
- b = 0.582102
- c = -0.0002646
- d = -0.0000009
- e = 1.09e-8
- f = -1.63e-11

For women, the constants are:

- a = 594.31747775582
- b = -27.23842536447
- c = 0.82112226871
- d = -0.00930733913
- e = 0.00004731582
- f = -0.00000009054

## What is Wilks IPF Powerlifting?

**Wilks IPF** (International Powerlifting Federation) refers to the specific Wilks formula used by the **IPF**, which is the governing body for powerlifting internationally.

The IPF Wilks formula is slightly different from the original Wilks formula and is used to determine the best overall lifters at **IPF-sanctioned competitions**.

## What Is a Good Wilks Score?

A good **Wilks score** is generally considered to be above **400** for both men and women.

The interpretation of a Wilks score can vary based on factors such as **age**, **experience level**, and **competition level**.

Here’s a general guideline for interpreting Wilks scores:

- Above
**500**: Elite level **450-499**: Advanced level**400-449**: Intermediate level**350-399**: Novice level- Below
**350**: Untrained level

It’s important to note that the **Wilks score** is a **relative measure**, and a “good” score can vary based on the individual’s goals and the level of competition they are participating in.

As the sport of powerlifting continues to evolve, the standards for what constitutes a good Wilks score may change over time.

## Is 350 a good Wilks score?

A Wilks score of **350** is generally considered a **novice level** score.

According to the guidelines mentioned earlier, a score below **350** is classified as an **untrained level**.

While a 350 Wilks score is a solid starting point, it would not be considered a good score for experienced or competitive lifters.

## Is a 450 Wilks good?

Yes, a Wilks score of **450** is considered a **good score**. Based on the guidelines, a Wilks score between **450-499** is classified as an **advanced level**.

This means that a lifter with a 450 Wilks score has reached a proficient level of strength and is likely competitive in their weight class.
