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 riseover 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?

  1. First, determine the rise for every unit run.

    This would be the total units y for every unit x.

  2. Next, determine the run for every unit rise.

    This would be the total unit x for every unit y.

  3. Finally, calculate the slope percent.

    Calculate the total slope percent using the values from steps 1 and 2 along with the formula.


What is a percent slope?

A percent slope is a measure of a slope with a base of 100, also known as a percentage.
