Enter the rise and run of a slope into the calculator. The calculator will evaluate and display the percent slope.

## Percent Slope Formula

The following formula is used to calculate the percentage of a slope of a line with respect to rise over run.

% S = Ri / R * 100

- Where %S is the percent slope
- Ri is the rise
- R is the run

## Percent Slope Definition

A percent slope is simply the slope of a line displayed as a percentage instead of a ratio of rise to run.

## Percent Slope Example

How to calculate percent slope

**First, determine the rise for every unit run.**This would be the total units y for every unit x.

**Next, determine the run for every unit rise.**This would be the total units x for every unit y.

**Finally, calculate the slope percent.**Calculate the total slope percent using the values from step 1 and 2 along with the formula.
