The Total Cost of Ownership of a Jet or Turboprop: Everything Beyond the Purchase Price
The first two posts of this July block established two things: that owning an aircraft is governed by thresholds (hours, mission, time value, resilience), and that “owning” is a spectrum of access models. Our composite company Vantor — a €180m European industrial group flying ~260 hours a year — came out tilting toward fractional ownership of a right-sized turboprop or light jet as a stepping stone.
This week we get concrete about the number everyone underestimates: what does owning actually cost? Not the purchase price — the total cost of ownership, or TCO. Because the purchase price is the number every broker quotes, every article headlines, and every enthusiastic executive fixates on, and it’s the least decision-relevant cost in the entire analysis. A €6m aircraft doesn’t cost €6m; it costs €6m to acquire and then something like €2m a year to own and operate, and it’s that second number — and especially the all-in cost per hour it implies — that actually determines whether ownership makes sense.
Let me build the TCO from the ground up, using Vantor’s situation to keep it concrete. The exact figures are illustrative and will vary by aircraft, region, and utilisation — but the structure is what matters, and the structure is universal.
Why the purchase price misleads
The purchase price is a single, visible, up-front number, which is exactly why it dominates the conversation and exactly why it’s dangerous. It anchors everyone on acquisition when the real economics live in operation. Two aircraft with identical purchase prices can have annual operating costs that differ by 40%. An aircraft that’s cheaper to buy can easily be more expensive to own — older airframes, out-of-favour types, and aircraft with expensive engine maintenance profiles are frequently “bargains” on purchase price and disasters on TCO.
The discipline is to stop asking “what does it cost to buy?” and start asking “what does it cost to own for the next five years, all in, per hour flown?” That question has a very different answer, and it’s the answer that matters.
TCO breaks into four categories: fixed costs, variable costs, periodic costs, and depreciation. Let me take them in turn.
Fixed costs: the ones that accrue whether you fly or not
Fixed costs are the heart of the ownership risk, because they don’t care how much you fly. Whether Vantor flies 100 hours or 400 hours next year, these costs are roughly the same — which is exactly why low utilisation is so punishing and why the whole thresholds discussion in the first post hinged on hours.
For a light jet or premium turboprop operated for a company like Vantor, the annual fixed costs look roughly like this:
Crew. Two pilots (salaries, benefits, recurrent training, duty travel and expenses). For a professionally-crewed light jet, this is commonly the largest single fixed line — on the order of €300,000+ a year. A single-pilot turboprop reduces this substantially, which is one reason turboprops can have dramatically better economics at lower utilisation.
Hangarage. Keeping the aircraft hangared rather than parked outside — €40,000–€80,000 a year depending on location and aircraft size. Call it €50,000.
Insurance. Hull (the aircraft value) plus liability. For a light jet, commonly €60,000–€120,000 a year depending on values, crew experience, and use. Call it €80,000.
Management fee. If the aircraft is run by an aircraft management company rather than an in-house department (the usual choice for a single aircraft), the management fee is a fixed annual cost — commonly €120,000+ a year for the management relationship itself, separate from the operating costs it administers.
Subscriptions and services. Navigation databases, charting, flight-planning services, connectivity, weather, maintenance tracking. Individually small, collectively €30,000–€50,000 a year. Call it €35,000.
Cost of capital. This is the one companies most often omit, and it’s real. The money tied up in a €6m aircraft has an opportunity cost — whether it’s the interest on financing or the return that capital could have earned elsewhere. At even a modest cost of capital, this is €250,000–€350,000 a year on a €6m asset. Omitting it is one of the most common ways ownership analyses flatter themselves. Call it €300,000.
Add these up and Vantor’s annual fixed cost is roughly €885,000 before flying a single hour. That number is the reason the thresholds matter: it’s incurred whether the aircraft flies 100 hours or 400. Spread over 100 hours it’s €8,850/hour of pure fixed cost; spread over 400 hours it’s €2,210/hour. Same aircraft, same fixed cost, utterly different economics — driven entirely by hours.
Variable costs: the ones that scale with flying
Variable costs are incurred per hour flown. They’re easier to reason about because they scale linearly, and they’re the costs charter operators are really selling you when they quote an hourly rate.
For Vantor’s light jet, per flight hour:
Fuel. The largest variable cost, sensitive to both aircraft efficiency and fuel price — on the order of €1,200/hour for a light jet at current prices.
Maintenance reserves. The per-hour accrual for scheduled maintenance, engine overhaul programmes (like the hourly-cost engine programmes most operators enrol in), and airframe maintenance. This is real money set aside every hour to fund maintenance that arrives later — commonly €800–€1,000/hour for a light jet. Call it €900/hour.
Landing, handling, and en-route charges. Airport fees, ground handling, navigation charges — highly variable by route, but averaging perhaps €400/hour for Vantor’s European mission profile.
Catering and miscellaneous. €100/hour or so.
Total variable cost: roughly €2,600/hour. Over Vantor’s 260 hours, that’s about €676,000 a year in variable cost.
Periodic costs: the ones that arrive in lumps
Periodic costs are real, large, and lumpy — they don’t arrive smoothly, which is exactly why they’re easy to underestimate in a casual analysis and brutal when they land.
Heavy maintenance checks. Airframe inspections at defined intervals (calendar or hours) that can cost hundreds of thousands and ground the aircraft for weeks. Some of this is captured in hourly reserves, but not all, and the timing creates cash-flow lumps.
Refurbishment. Interior refresh and exterior paint every several years — €100,000s when they come due, and necessary both for the flying experience and for residual value.
Avionics upgrades. Mandated equipment changes and desirable upgrades over an ownership period — periodic and sometimes substantial.
Unscheduled maintenance and AOG. Aircraft-on-ground events — unplanned, sometimes expensive, and requiring either downtime or backup charter to cover the missed mission.
Amortised across the ownership period, these periodic costs commonly add €100,000–€200,000 a year for a light jet. Call it €150,000 for Vantor. The key point isn’t the average — it’s that these arrive unevenly, so a company needs the cash cushion to absorb a heavy check and a refurbishment landing in the same year without stress. This links straight back to the resilience threshold from the first post.
Depreciation: the largest cost almost nobody models
Depreciation is the cost that doesn’t show up in the bank statement, which is exactly why it’s the one most often ignored — and it’s frequently the single largest cost of ownership.
An aircraft loses value over time. The rate depends heavily on type, age, market conditions, and how well it’s maintained, but a working assumption for a modern light jet might be 5–8% of value per year in the early years. On a €6m aircraft, that’s €300,000–€480,000 a year of value evaporating whether or not you fly. Call it €400,000 for Vantor.
Depreciation is distinct from cost of capital — they’re two different things, and both are real. Cost of capital is the opportunity cost of the money tied up in the asset. Depreciation is the decline in the asset’s value. A rigorous TCO includes both, and companies that include neither (looking only at cash operating costs) understate the true economic cost of ownership by a large margin. Depreciation is also where aircraft selection matters enormously — some types hold value far better than others, and a type that depreciates slowly can be cheaper to own over five years than a cheaper-to-buy type that depreciates fast. This is one of the highest-leverage places where independent, non-commissioned advice pays for itself.
Vantor’s TCO, assembled
Let’s put it together for Vantor at 260 hours a year:
- Fixed costs: ~€885,000
- Variable costs (260 hrs × €2,600): ~€676,000
- Periodic costs (amortised): ~€150,000
- Depreciation: ~€400,000
- Total economic TCO: ~€2,111,000 a year
Now the number that actually decides: all-in cost per hour. €2,111,000 ÷ 260 hours = roughly €8,100 per hour. The cash cost per hour (excluding depreciation) is about €6,580.
Here’s why that number is the whole game. A comparable light jet on the charter or card market might cost Vantor something like €5,500–€7,000 per hour, all in, with zero fixed-cost risk and zero capital tied up. At 260 hours, full ownership’s all-in cost per hour (~€8,100) is higher than chartering the same capability. This is exactly the conclusion the first two posts pointed toward: at 260 hours, full ownership isn’t obviously the cheapest option — it can be the most expensive — which is precisely why fractional or charter often win in the grey zone.
The number that changes everything: hours
Watch what happens to Vantor’s all-in cost per hour as hours change, because the fixed and periodic and depreciation costs (~€1,435,000) barely move while the hours they’re spread over do:
- At 260 hours: (€1,435,000 fixed/periodic/depreciation + €676,000 variable) ÷ 260 = ~€8,100/hour
- At 400 hours: (€1,435,000 + €1,040,000) ÷ 400 = ~€6,190/hour
- At 600 hours: (€1,435,000 + €1,560,000) ÷ 600 = ~€4,990/hour
At 260 hours, ownership costs ~€8,100/hour and loses to charter. At 600 hours, ownership costs ~€4,990/hour and beats charter comfortably. Nothing about the aircraft changed — only how many hours the fixed costs are spread across. This is the single most important dynamic in aircraft ownership economics, and it’s the entire subject of next week’s post: annual flight hours as the number that decides.
The common TCO mistakes
A few errors I see repeatedly, worth flagging:
Comparing purchase prices instead of TCO. The most common and most expensive error. A cheaper-to-buy aircraft with a thirstier engine, worse residual, and higher maintenance profile can cost far more to own. Always compare five-year TCO, not sticker price.
Omitting cost of capital and depreciation. Looking only at cash operating costs understates the true economic cost of ownership by often 30–40%. These non-cash and opportunity costs are real and belong in every honest analysis.
Using optimistic hours to compute cost per hour. The cost-per-hour figure is only as honest as the hours it’s divided by. Computing TCO/hour on hoped-for hours produces a flattering number that reality won’t deliver — the exact trap the first post warned about.
Underestimating the lumpiness of periodic costs. The average annual periodic cost is fine for TCO; but the timing matters for cash planning, and a company that budgets only the average can be caught out when a heavy check and a refurbishment land together.
Ignoring type-specific residual. Two aircraft with similar operating costs can have very different depreciation curves. Residual value is a first-order TCO input, not a footnote.
Where this leaves Vantor, and where the block goes
Vantor’s TCO analysis reinforces everything the first two posts concluded. At 260 hours, full ownership’s all-in cost per hour is high enough that fractional or charter genuinely competes — which is why the recommendation was fractional as a stepping stone. But the TCO also shows exactly what would change the answer: more hours. If Vantor’s utilisation grew toward 400–600 hours, the all-in cost per hour would fall below charter, and full ownership would become clearly correct.
Which means the entire ownership decision, across all four of this month’s posts, comes down to a single anchoring number: how many hours will you actually fly? That’s next week’s post, and the close of the July block — annual flight hours as the number that decides whether buying an aircraft makes sense.
The companies that get TCO right treat the purchase price as the least interesting number in the analysis and build the full picture — fixed, variable, periodic, depreciation — before making any decision. The companies that get it wrong fixate on the sticker price, omit cost of capital and depreciation, and discover the real cost of ownership after they own it, when it’s expensive to correct.
At AYRAM we build TCO models for companies as part of independent buy-side advisory. Because we take no commission from sellers, brokers, or management companies, our TCO models have no incentive to understate any line — which is unfortunately not true of every cost projection a company will be shown during an acquisition. The most valuable TCO analysis is the one built by someone with no stake in the answer, because the honest number is sometimes the one that says “this costs more than you were told”.
If your company is evaluating ownership, the TCO — built properly, with every line and no optimistic hours — is where the real decision lives. It’s worth building before, not after, you commit.
