Backpacking Stove Fuel Burn Calculator
Calculate camping stove fuel needed by trip length, meals, and stove type.
Plan canister, alcohol, white gas, or wood-stove fuel for any backpacking trip.
Total Fuel Needed
Backpacking Stove Fuel Burn Rate
Fuel needs depend on stove efficiency, what you’re cooking, and water volume boiled. Two factors dominate:
- Boil time and water mass for hot meals and drinks
- Cold/wind conditions that reduce stove efficiency
Typical stove burn rates (per liter of water boiled, sea level, calm):
| Stove Type | Fuel Use | Notes |
|---|---|---|
| Canister (Pocket Rocket, MSR Reactor) | ~10-12 g per liter | Convenient, regulator helps in cold |
| Canister with reflector windscreen | ~7-9 g per liter | More efficient |
| White gas (MSR Whisperlite) | ~12-15 mL per liter | Field-cleanable, cold-weather king |
| Alcohol (Trangia, Vargo) | ~30-40 mL per liter | Quiet, no priming |
| Esbit / solid fuel tablets | ~14 g per liter | Very light but slow + sooty |
| Wood stove (Solo, Vargo) | Forage in field | Free fuel but variable |
Daily fuel needs by trip style:
| Style | Hot Meals/Day | Hot Drinks | Daily Fuel (canister) |
|---|---|---|---|
| Light dayhike | 0 | 1-2 cups | 5-10 g |
| Casual overnight | 1-2 cooked + drinks | 2-3 cups | 25-40 g |
| Standard backpacker | 2 hot meals + drinks | 4 cups | 40-60 g |
| Cold-weather / winter | 3 meals + lots of melt water | 6+ cups | 80-150 g+ |
Cold weather adjustments:
- 20-30% more fuel needed below freezing (30°F / -1°C)
- 50%+ more for melting snow for water
- White gas wins below 20°F (-7°C); butane canisters underperform
Standard canister sizes (isobutane):
| Size | Net Weight | Boil-Liters Estimate |
|---|---|---|
| 100 g (small) | 100 g | ~8-10 L |
| 220 g (medium) | 220 g | ~18-22 L |
| 450 g (large) | 450 g | ~38-45 L |
Fuel buffer rule: Always carry 20% more fuel than calculated. Reasons:
- Wind or low temps drain fuel faster
- Spilled water or burnt meals = re-boil
- Re-warming is harder than first-boil
- Empty canisters near end of trip = bad surprise
Water needs per backpacker:
- 1 L for breakfast (oats / coffee + eating)
- 0.75-1 L for cooked dinner + drink
- 1-2 L drinking refills (boil-as-treatment)
- Total daily boil: 2-4 L
Alcohol stove caveat: Alcohol stoves use 3× the volume of gas stoves but the fuel weighs less per liter. Total trip weight is similar; alcohol wins for short trips, canister wins for long trips.
