Enter the highest and lowest elevation points into the calculator to determine the elevation difference. This calculator can also evaluate any of the variables given the others are known.

Elevation Difference Formula

The following formula is used to calculate the elevation difference.

ED = H - L


  • ED is the elevation difference (meters)
  • H is the highest elevation point (meters)
  • L is the lowest elevation point (meters)

To calculate the elevation difference, subtract the lowest elevation point from the highest elevation point. The result is the variation in altitude between the highest and lowest points in a particular area.

What is an Elevation Difference?

Elevation difference, also known as relief, refers to the variation in altitude between the highest and lowest points in a particular area. It is a measure used in geography to understand the topography or terrain of a region. This can be calculated by subtracting the lowest elevation from the highest elevation within a specified area. Elevation difference is important in various fields such as civil engineering, architecture, and environmental science for planning and designing purposes.

How to Calculate Elevation Difference?

The following steps outline how to calculate the Elevation Difference.

  1. First, determine the highest elevation point (H) in meters.
  2. Next, determine the lowest elevation point (L) in meters.
  3. Next, gather the formula from above = ED = H – L.
  4. Finally, calculate the Elevation Difference.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

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

highest elevation point (H) = 500 meters

lowest elevation point (L) = 200 meters
