Ownership exit economics
Depreciation on a fractional share is the difference between what you paid for the interest and what you actually net when you leave, after every deduction the agreement permits. There is no standard percentage. Aircraft type, holding period, and market conditions all matter, but in an ordinary market the valuation method and deduction schedule written into your purchase agreement usually move the number further than the market does.
That is why this belongs in the cost model rather than in a footnote. The capital lost between entry and exit is spent as surely as any fee, and it is the one component a monthly statement will never itemize for you.
The short answer
A whole aircraft has a market. Brokers, published references, and comparable transactions all bear on what it fetches, and an owner who dislikes an offer can decline it and wait. A fractional interest has something narrower: a contractual process, with a defined counterparty, a defined method, and a defined timetable.
That narrowing is the point of the structure, and it is genuinely valuable, it is what makes an exit predictable. But it also means the owner’s realized depreciation is a function of documents rather than of negotiation. Two buyers holding identical interests in identical aircraft for identical periods can net different amounts because their agreements define value and deductions differently.
So the useful question is not what fractional aircraft depreciate by. It is what your specific agreement will pay you, under what conditions, and how far that sits from what the airframe is worth. That difference is the part of the analysis that the fractional jet share cost breakdown can only carry as an assumption.
The clause that matters
Most buyers read the sentence that says the provider will repurchase the interest, and stop. The sentences that determine the amount sit further down. Before signing, establish each of the following:
One item on that list deserves particular attention: the base a deduction is calculated against. A percentage deduction applied to the value at exit rather than to the original purchase price behaves very differently in a soft market, because it takes its share of a number that has already fallen. The deduction and the decline compound instead of offsetting.
These terms are negotiated, or not, at acquisition. Once the interest is held, the owner’s leverage is largely spent, which is why the diligence sequence on selling a fractional share begins years before anyone intends to sell.
Structural comparison
A general description of how exit value is determined under each structure. Specific terms vary by provider and by agreement; confirm your own before relying on any line.
| Factor | Fractional share | Whole aircraft | Fractional lease | Jet card |
|---|---|---|---|---|
| Who holds the asset | The owner, as an interest in a specific aircraft | The owner outright | The lessor | No aircraft is held |
| Who bears residual risk | The owner, within the contract's bounds | The owner, without limit | The lessor | Nobody, on the client's side |
| How exit value is determined | The agreement's valuation method | Open-market negotiation with a buyer | Not applicable to the lessee | Not applicable |
| Typical deductions at exit | Remarketing, administrative, and condition adjustments | Broker commission, pre-buy remediation, and closing costs | Return-condition and end-of-term charges | Unused-funds and expiry provisions, where they exist |
| Time from decision to cash | Notice period plus a contractual settlement window | Marketing period, often measured in months | Ends with the lease term | Governed by the card's refund terms |
Reading the guarantee
The word guaranteed does a great deal of work in fractional marketing, and it is worth being precise about what it secures. It secures a buyer. It secures a process and a timetable. In almost every program it settles at a value determined at the time of exit, less whatever the contract allows to be deducted.
What that buys is real: an owner is never left holding an illiquid interest with no route out. What it does not buy is protection against the aircraft being worth less than it was. Buyers who hear guaranteed and model a full recovery of acquisition capital have substituted a liquidity assurance for a price assurance, and the gap between the two is the whole of this page.
There is also a timing dimension that rarely gets modeled. Because exit generally requires notice, the decision to leave has to be made before the owner knows the market they will be exiting into. Anyone approaching the end of a term should read the fractional share renewal options alongside the repurchase terms, since the two decisions are made in the same window.

Two different questions
Economic depreciation is the decline in what the asset is worth. Tax depreciation is a statutory cost-recovery mechanism applied to qualifying business-use property. They are computed differently, they answer different questions, and an owner can take a substantial deduction in one year and still realize a substantial economic loss at exit. Neither result implies anything about the other.
On the statutory side, IRC §168(k) currently provides 100% additional first-year depreciation for qualified property acquired after January 19, 2025, made permanent by the legislation enacted in 2025. Whether any particular aircraft interest qualifies depends on acquisition and placed-in-service timing, qualified business use, listed-property rules under IRC §280F, substantiation, and the entity through which the interest is held. Disposition can trigger recapture and basis consequences that reverse part of an earlier benefit.
None of that is a determination this page can make, and none of it is tax advice. It is described here only so that a cost model does not silently treat a deduction as if it were a recovery of value. Route the entire question to your own qualified tax advisor and counsel, and verify current law at the time of acquisition.
Modeling
A single exit assumption is the least defensible input in any ownership model, because it is the one furthest in the future and the one the buyer has least control over. Replace it with a range, and observe what the range does to the decision.
Illustrative arithmetic using round numbers, not any operator’s pricing: take a $1,000,000 interest exited after five years at 70% of entry value, with a 5% remarketing deduction taken against the exit value. Proceeds are $665,000, and the capital consumed is $335,000. Spread over 250 occupied hours across those five years, that is roughly $1,340 per hour of cost sitting alongside every fee and every occupied charge. Move the exit assumption to 60% and the same calculation produces about $1,720 per hour.
A $380 per hour swing from one assumption is usually larger than the difference between the programs being compared. That is the argument for carrying depreciation explicitly through a fractional jet cost calculator rather than as a footnote, and for testing the ownership case against a lease in the fractional versus whole aircraft ownership framework before capital is committed.
Common questions
The exit examples on this page are illustrative arithmetic using round numbers and are not any operator’s pricing, valuation method, or projection of value. Contract terms, valuation methods, and deduction schedules vary by provider and by agreement and change over time; rely on your own executed documents. Tax references are to IRC §168(k) and IRC §280F and are general information only, not tax, legal, or investment advice, economic value and tax treatment require separate professional analysis by your own qualified tax advisor and counsel.
