Aircraft Fuel Cost Calculator
Trip and hourly fuel cost from burn rate, time and price — the first number in every operating-cost conversation.
Fuel cost = burn rate × time × price. Trivial math, decisive number — it anchors rental rates, charter quotes and ownership budgets alike.
Use BLOCK time (taxi included) for cost math and your POH/FMS cruise figure plus a climb allowance for the burn rate — brochure burn rates are sea-level optimism.
With your numbers: 9.5/h for 2.4 h needs 22.8 units of fuel; at 6.45 each, the trip costs 147.06.

Free aircraft fuel cost calculator for any fuel and any aircraft: burn × time × price with honest block-time framing — the anchor number for trips, budgets and quotes.
About Aircraft Fuel Cost Calculator
Every aviation cost conversation starts here: burn rate times time times price. The arithmetic is trivial; the discipline is in the inputs. Burn rate should be your real-world figure — the POH cruise number plus a climb allowance, or better, your engine monitor's measured average — because brochure rates are sea-level, perfectly-leaned optimism. Time should be block time (engines running), since taxi fuel is real money at both ends. Price should be today's, not the price you remember; avgas and Jet-A both move. With honest inputs this calculator anchors trip planning, rental-vs-ownership comparisons, charter quotes and the fuel line of every operating budget — and the per-trip output multiplied across a year's flying is usually the number that surprises people.

Frequently asked questions
How do I find my aircraft's real fuel burn?+
Measure it: top off, fly a representative flight, top off again, and divide gallons by block hours — or pull the average from an engine monitor's fuel-flow totaliser across ten flights. Real-world burns typically run 10-20% above the brochure cruise figure once climb, taxi and imperfect leaning are included. One measured number makes every future cost calculation trustworthy.
Why does block time matter for fuel cost?+
Because engines burn fuel from start to shutdown, not just in cruise: ten minutes of taxi at each end of a one-hour flight adds meaningful percentage to the trip's burn, especially for training flights with long ground portions. Cost math on airborne time systematically understates the fuel line — schools and clubs price on block (Hobbs) time for exactly this reason.
How should I budget for fuel price volatility?+
Run this calculator at three prices — current, +20%, and your local 12-month high — and budget on the middle scenario. Fuel is most owners' largest variable cost, and it moves with crude, refining margins and airport-specific pricing power. For bigger operations, the fuel scenario modeler on this site formalises exactly this three-price exercise across a month's flying.
Is this tool private — who can see my entries?+
Only you. Entries live in your browser's local storage and never leave your device, so there is no account, no cloud sync and no one else with access. Because the data is device-local, export a CSV backup before clearing browser data or switching computers.
How do I back up or print these records?+
Use the Export CSV button below the table: it downloads your full fuel cost estimate as a spreadsheet-ready file. From there you can print a clean copy, archive it with your records folder, or import it into any other system. Exporting monthly is a good habit since the working data lives only in your browser.
