A golf course of standard playing difficulty has a slope rating of 113, and slope ratings range from a minimum of 55 (very easy) to a maximum of 155 (extremely difficult).

A slope rating is calculated from the difference in a bogey course rating and a scratch course rating, more commonly known as the course rating.

## How is golf course slope rating calculated?

The USGA uses a standard formula to figure out your handicap index. First it calculates your handicap differential by subtracting the course rating from your adjusted gross score. The difference is multiplied by 113 — the standard slope rating — and the product is divided by the course’s slope rating.
