Enter the slope run and the slope rise into the Reverse Slope Calculator. The calculator will evaluate and display the Reverse Slope. 

Reverse Slope Formula

The following formula is used to calculate the Reverse Slope. 

RSL = X / Y
  • Where RSL is the Reverse Slope (run/rise)
  • X is the slope run 
  • Y is the slope rise 

To calculate a reverse slope, divide the slope run by the slope rise.

How to Calculate Reverse Slope?

The following example problems outline how to calculate Reverse Slope.

Example Problem #1:

  1. First, determine the slope run.
    • The slope run is given as: 50.
  2. Next, determine the slope rise.
    • The slope rise is provided as: 30.
  3. Finally, calculate the Reverse Slope using the equation above: 

RSL = X / Y

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

RSL = 50 / 30 = 1.667 (run/rise)

Example Problem #2: 

For this problem, the variables required are provided below:

slope run = 60

slope rise = 20

Test your knowledge using the equation and check your answer with the calculator above.

RSL = X / Y = ?
