The following formula is used to calculate the Grade Slope.

GS = GY / GX * 100
• Where GS is the Grade Slope (%)
• GY is the grade rise
• GX is the grade run

To calculate a grade slope, divide the grade rise by the grade run, then multiply by 100.

## How to Calculate Grade Slope?

The following example problems outline how to calculate Grade Slope.

Example Problem #1:

1. First, determine the grade rise.
• The grade rise is given as: 50.
2. Next, determine the grade run.
• The grade run is provided as: 1000.
3. Finally, calculate the Grade Slope using the equation above:

GS = GY / GX * 100

The values given above are inserted into the equation below and the solution is calculated:

GS = 50 / 1000 * 100 = 5 (%)

Example Problem #2:

For this problem, the variables needed are provided below:
