Enter the rise and run of your driveway into the calculator to determine the slope percentage. This calculator helps in assessing the steepness of a driveway, which is important for safety and construction standards.

## Driveway Slope Formula

The following formula is used to calculate the slope of a driveway:

Slope () = (Rise / Run) * 100

Variables:

- Rise is the vertical change in height (inches)
- Run is the horizontal distance over which the rise occurs (feet)
- Slope is the steepness or incline of the driveway expressed as a percentage

To calculate the driveway slope, divide the rise by the run and then multiply by 100 to get the percentage.

## What is a Driveway Slope?

A driveway slope is the measure of how steep a driveway is. It is calculated as the ratio of the vertical rise to the horizontal run, expressed as a percentage. The slope is an important consideration in driveway design, affecting the ease of access, drainage, and safety. Driveways with too steep a slope can be difficult to navigate, especially in adverse weather conditions, while those with too gentle a slope may have issues with water pooling.

## How to Calculate Driveway Slope?

The following steps outline how to calculate the Driveway Slope:

- First, measure the rise (the vertical height) of the driveway in inches.
- Next, measure the run (the horizontal distance) of the driveway in feet.
- Convert the run from feet to inches to match the units of the rise.
- Use the formula: Slope (%) = (Rise / Run) * 100 to calculate the slope.
- Enter the rise and run into the calculator to get the slope percentage.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Rise of the driveway = 15 inches

Run of the driveway = 20 feet
