Enter the rise and run of a slope into the calculator. The calculator will evaluate and display the percent slope. This calculator can also evaluate the rise or run when given the other variables.

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

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

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.
