Elevation Gain Calculator
Elevation Gain Calculator
Open a GPX track · See total climb · Read any segment
.gpx files only · stays on your device, never leaves your browser
Enter two distances along the track (in miles) to read the gain, loss, and net change between them. Or click two spots on the chart below.
What This Tool Does
Distance tells you how far. Elevation tells you how hard. A flat twelve-mile day and a twelve-mile day with four thousand feet of climbing are not the same day, and the difference is the thing your legs feel.
Open a GPX track and this tool reads the elevation data in the file, then gives you the numbers that matter: total gain, total loss, your high and low points, net change, and the full length of the track. It draws an elevation profile of the whole route so you can see where the climbing actually happens.
Then it goes one step further. Switch to point-to-point mode — or click two spots on the profile chart — and it reads the gain and loss for just that stretch. Useful when you want to know what a single day, or the climb to one pass, is going to cost you.
Everything runs in your browser. Your GPX file never leaves your device.
How to Use It
- Click Open and select your GPX track file — or drag it into the drop zone
- The tool reads the track and shows total gain, loss, high point, low point, net change, and length
- The elevation profile chart draws the whole route automatically
- To read a single segment, switch to Point to Point and enter a "from" and "to" mileage — or just click two spots on the chart
- The gain, loss, net change, and distance for that segment appear instantly
When a GPX Has No Elevation Data
Some GPX files don't carry elevation data — they record only latitude and longitude. When that happens, this tool tells you so rather than guessing.
If you see the no-elevation notice, re-export your track from Gaia GPS, CalTopo, or your GPS device with elevation included, then open it again. Most mapping tools include elevation by default or offer it as an export option.
A note on accuracy: elevation recorded by consumer GPS devices is noisier than horizontal position, and different tools report total gain differently depending on how they filter that noise. Treat the numbers here as a solid estimate for planning, not a surveyed measurement — the same caution applies to every elevation tool, ours included.
Who Built This and Why
Hiking America builds navigation tools for long-distance hikers — primarily for the American Discovery Trail and the Great American Rail-Trail. Knowing the climbing ahead is part of planning any long route, and reading it off a raw GPX file by hand is tedious. So we built this.
If you're planning a long-distance hike and want to know more about our GPS tracks and waypoint data, hikingamerica.com is the place to start.
