Fuel Tankering Calculator

Is carrying extra fuel from the cheap airport worth it? Burn penalty, fuel arriving, and net saving — the tankering decision in one screen.

Tankering profits when the price spread beats the burn penalty: carrying extra weight burns roughly 2.5-4.5% of the carried fuel per flight hour on transport aircraft.

Penalty factors: ~2.5-3% /h for efficient narrowbodies, 3.5-4.5% for older/heavier types — use your fleet's flight-planning value. Check landing-weight and tank limits before the economics.

With your numbers: Tankering 2,000 kg for 2.5 h at a 3.5%/h penalty burns 175 kg; 1,825 kg arrives, worth the 1.05−0.78 spread — net 356.25 on the leg.

About Fuel Tankering Calculator

Tankering — lifting more fuel than the leg needs because it's cheaper where you are than where you're going — is a pure arithmetic decision wearing an operational costume. Carrying the extra weight costs fuel (transport-category rule of thumb: 2.5-4.5% of the carried fuel per flight hour), so the question is whether the price spread beats the burn penalty on this leg. This calculator runs the exact trade: penalty fuel burnt, fuel actually arriving, and the net saving in currency. Airlines run this in flight-planning systems across whole networks; charter operators, corporate departments and even piston owners crossing big avgas spreads face the identical math at smaller scale. The constraints the economics must respect: maximum landing weight, tank capacity, and performance margins — the note exists because a profitable tanker that busts landing weight isn't profitable.

Frequently asked questions

What burn penalty factor should I use for tankering?+

Your flight-planning system's cost-of-weight figure if you have one; otherwise working values: ~2.5-3%/h for modern efficient narrowbodies, 3-4%/h for regional jets and older narrowbodies, 4-4.5%/h for heavier or less efficient types, and proportionally smaller but still real numbers for turboprops and pistons. The factor expresses how much of the CARRIED fuel is burnt per hour just to carry it — small differences compound on long legs, which is why long-haul tankering rarely pays.

When does tankering NOT pay despite a price spread?+

Long legs (the penalty compounds against you), landing-weight limits that force the extra fuel to shrink payload, short-field destinations where the extra weight costs performance margin, and small spreads — under roughly 10-15% price difference the penalty usually eats the gain on legs beyond an hour or two. There's also the carbon angle: penalty fuel is pure extra emissions, and several operators now apply an internal CO2 cost that tightens the threshold.

Does tankering make sense for piston GA?+

At smaller absolute numbers, yes — the same equation with avgas spreads that routinely exceed $2/gallon between neighbouring fields. A 182 carrying 30 extra gallons across a $1.80 spread nets real money against a tiny burn penalty on a short leg. The GA constraints mirror the airline ones: stay inside W&B and landing weight, and never trade fuel economics against runway performance on a hot day.

Where is this data stored?+

Everything you enter is saved in your browser's local storage on your own device — nothing is uploaded to any server. Your records stay completely private, work offline, and load instantly. Use the CSV export regularly to keep an off-device backup copy.

Can I export these records for an audit?+

Yes — one click exports your complete tankering analysis as a CSV file that opens in Excel, Google Sheets or Numbers. The export preserves every column exactly as entered, so you can print it, attach it to paperwork, or hand it to an inspector, buyer or insurance underwriter as a supporting summary alongside your official records.
