Hill Grade Calculator

Enter the total elevation gain and the total horizontal distance traveled from trailhead to summit to calculate the average hill grade.

Hill Grade Formula

The following formula is used to calculate the percentage hill grade of a trail or hike.

G = EG / HD *100

  • Where G is the hill grade %
  • EG is the elevation gain (ft/m/ect.)
  • HD is the horizontal straight line distance from head to summit

Hill Grade Definition

A hill grade is defined as the percentage of slope on average of a certain hiking trail.
