The Fractional Cost Model: Fraction, Management Fee, Hours, Exit
A fractional share is a slice of an aircraft plus a contract to operate it. A lease is a right to use someone else’s aircraft. The flight-department narrative is on the decision guide. Who signs the note is on who borrows. This page is the bill.
Four numbers, not one payment
- Acquisition. The price of the fraction (often 1/16, 1/8, or 1/4 of a type). This is the piece that can be financed. The management company is not the collateral; the share agreement and the program’s remarketing rules are.
- Monthly management. A fixed fee for crew, insurance, and scheduling. It does not shrink if you fly zero hours.
- Occupied hourly rate. What you pay when you actually fly. Compare it with charter on the same cabin, not with airline coach.
- Exit. The contract’s remarketing or repurchase formula. “Ownership” that you cannot sell except back to the program at their formula is not the same asset as a whole aircraft on the FAA registry in your name.
How to compare it with a lease in the calculator
Finance only the acquisition piece in the loan calculator. Then add management and a realistic hour total outside the calculator, because those are operating costs, not principal. A lease quote is almost entirely operating cost. Comparing a fractional loan payment with a lease payment, and ignoring management and hours, makes the share look cheaper than it is.
Tax treatment of a share is not automatic bonus depreciation on the whole aircraft. Your CPA has to look at what you actually own under the program documents. Do not assume a 1/8 share produces 100% of the aircraft’s depreciation.
Questions buyers actually ask
Is a fractional share easier to finance than a whole aircraft?
Not automatically. Some programs offer in-house financing. Outside lenders may decline because the collateral is a contract right, not an airplane they can repossess and ferry.
What hours make a share cheaper than charter?
There is no universal crossover. Build it from your occupied-hour rate, management fee, and the charter quote on the same route. The crossover moves every time the hourly rate is revised.
