Hiking Elevation Gain Calculator — Total Climb & Slope | Hiking Calorie Calculator
Calculate total elevation gain, downhill descent, and trail slope percentage for your hikes.
Trail Elevation Details
Calculates total uphill climb and downhill descent. Ensures loop hikes that finish where they started still count all the climbing effort. Read formula documentation →
Trail Slope & Climb Inspector
See how your vertical climb and trail distance translate into percent slope, degrees, and extra muscle effort.
Worked Example: Out-and-Back Mountain Trail
A 10.0 km (6.2 mi) out-and-back hike starting at 400 meters altitude, climbing 5 km to a 1,000 meter pass (+600m), then walking back down the same path to 400 meters (-600m).
Example Inputs
- Total Distance
- 10.0 km (6.2 mi)
- Starting Elevation
- 400 m (1,312 ft)
- Highest Point Elevation
- 1,000 m (3,281 ft)
- Finishing Elevation
- 400 m (1,312 ft)
- Route Type
- Out-and-Back
Even though your net elevation change is 0 meters (because you finished where you started), your legs climbed 600 vertical meters uphill against gravity. Calorie calculators must use total climb (+600m), not net change (0m).

How the Calculation Works
Proven sports science formulas and practical trail estimates.
How Elevation Gain Burns Calories: Total vs. Net Ascent
In simple terms, lifting an object upward takes physical work against gravity. Lifting your own body weight and backpack up a mountain works the same way:
Why Net Elevation Doesn't Count Calories
If you hike a 10-mile mountain loop that climbs 3,000 feet and returns to your car, your net elevation change is exactly zero. But your body did not get "recharged" on the way down! Both climbing uphill and walking downhill burn calories. That is why calculators must always use total elevation gain, not the net change.
Mountain Topography & Trail Reading Tips
How to read trail maps, estimate steepness, and pace your climbs.
Reading Topo Maps
On standard topographic maps, contour lines show elevation. When lines are packed tightly together, the trail is very steep. When lines are spaced far apart, the trail is flat or gentle.
Zigzag Paths Save Energy
Switchbacks make trails longer so the climb stays gentle (around 8% to 10%). Walking a longer, gentler slope uses significantly less energy than scrambling straight up a steep face.
1,000 Feet per Hour
Most fit hikers climb about 1,000 to 1,300 vertical feet (300 to 400 meters) per hour on continuous uphill trails. Use this simple benchmark to plan how long your climbs will take.
Frequently Asked Questions
Clear, helpful answers to common questions about this calculation.
What is the difference between total elevation gain and net elevation change? +
Net elevation change is simply the difference between your finish point and starting point. Total elevation gain (or total ascent) adds up every uphill step along the whole hike. On a loop hike where you finish at your car, net elevation change is zero, but total climb might be thousands of feet!
Why does climbing hills burn so many more calories than walking flat? +
Walking on flat ground only takes energy to swing your legs and move forward. Walking uphill forces your muscles to lift your entire body weight and pack straight up against gravity with every single step.
How do you calculate percent slope from elevation and distance? +
Slope percentage is simply: (Elevation Gain ÷ Trail Distance) × 100. For example, climbing 500 feet over a 5,000-foot trail section equals a 10% slope.
Why do rolling hills feel so exhausting? +
Rolling trails feature repeated small ups and downs. Even if you never climb a high mountain peak, losing and regaining 50 to 100 feet dozens of times quickly adds up to the same climb as a big summit.
What makes a trail "steep" vs "gentle"? +
A climb of under 150 feet per mile (30 m/km) is gentle. Between 300 and 500 feet per mile (60–100 m/km) is a solid mountain trail. Over 800 feet per mile (150 m/km) is steep, challenging terrain where you will feel the burn quickly.
Why do GPS watches report higher climbing numbers than trail signs? +
GPS and altimeter watches have small natural reading wobbles of ±10 feet. Over a long hike with thousands of recorded points, these tiny fluctuations can add up to hundreds of feet of fake climb unless smoothed out.
