Owning a private jet costs $1.5 million a year before it ever leaves the ground

Full ownership of a $25 million jet doesn’t break even against chartering until you log roughly 250 to 400 flight hours a year. Below that, fixed costs of $1.5 million or more eat the budget regardless of usage.

NBAA pegs 250 hours as the point where full ownership becomes a good option. Fly below 150 hours and charter is almost always cheaper.

The Fixed-Cost Core: Where the Real Money Sits

A private jet’s budget has two layers. Fixed costs — crew salaries, hangar lease, insurance, management fees — stay constant whether the aircraft flies 50 hours or 500. Variable costs — fuel, engine reserves, landing fees, catering — move with each hour logged, but they never dominate the total.

This is why the “all-in hourly rate” number that brokers quote is misleading. It buries the cost that matters most: the seven figures you owe before the engines start. A light jet runs about $500,000 a year in fixed costs before any flying happens. An ultra-long-range jet starts at $2 million or more, per Flyius’s 2026 ownership table.

Owners who place their aircraft on a Part 135 charter certificate can claw back some of this. Third-party charter revenue offsets crew salaries and hangar leases, but it rarely turns a profit — at best it softens the annual loss. And it changes the insurance and maintenance profile.

Then there’s the behavioral failure. Prospective buyers consistently overestimate how many hours they’ll actually fly. Experts warn this leads to ownership structures that fail to spread fixed costs efficiently.

Break-Even Thresholds Don’t Scale Linearly

The break-even point is not one number. It shifts by aircraft class, and the published models don’t all agree. The table below pulls together the best available figures — but note the two rows where fixed-cost and hour data simply aren’t published anywhere reliable.

There’s a tension on the page. The National Business Aviation Association says 250 hours is where full ownership becomes generally a good option. The Flyius model pegs heavy jets at about 220 hours and ultra-long-range at about 190. The difference matters because the $25 million anchor sits at the bottom of heavy jet territory.

Part of the gap comes down to what’s in the model. A simple cost-per-hour comparison misses depreciation, financing, and downtime. Fold those in, and the threshold drifts upward — which is how you end up with a defensible range of 250 to 400 hours for a $25 million jet.

For lower utilization, the alternatives sharpen. Fractional and jet card programs reach financial break-even at lower hours than full ownership for most light and midsize jets. And flyers below 50 to 150 hours a year will find chartering the most cost-effective path, full stop.

How Financing Rates Quietly Move the Break-Even Line

Most owners don’t pay cash, and the loan terms shift the math in ways that are rarely quantified. A mid-2026 rate page from FLYING Finance lists starting rates near 6.37% for turboprops and jets. Pilothouse‘s 2026 financing guide quotes 5 to 15-year terms and class-specific ranges: 7.0% to 9.0% for midsize jets, 7.0% to 8.0% for large-cabin, and 6.0% to 7.5% for ultra-long-range.

The sensitivity is straightforward. On a $20 million loan — roughly 80% financing on a $25 million aircraft — each percentage point of interest adds about $200,000 a year. That’s a full crew salary. A buyer who pays 8% instead of 6.37% has pushed their annual fixed-cost burden up enough to meaningfully shift the break-even point higher.

Depreciation works on a different clock. The first five years of ownership are when a new aircraft loses market value fastest, making resale value a first-order cost, not a footnote.

Exit liquidity matters more than buyers realize. Lighter jets have deeper buyer pools and tend to move faster in a downturn. Large-cabin aircraft sit in a thinner market, and a slow sale doesn’t just mean a lower price — it means continuing to pay hangar, insurance, and management on an airplane you’re no longer flying.

Downtime Is a Cost, Not an Inconvenience

A grounded jet still eats fixed costs. Aircraft On Ground — the industry’s term for a plane stuck somewhere waiting on parts or technicians — turns maintenance from a variable cost into a fixed one. The meter keeps running on crew salaries, hangar, and insurance while the aircraft sits idle on a foreign ramp.

New and pre-owned aircraft face very different AOG profiles. A new Gulfstream or Bombardier comes with manufacturer warranty coverage and a factory support network built for quick response. A 15-year-old midsize jet may need a part that’s out of production, shipped from a third-party supplier — and every day it’s down is a day the owner pays for everything except the ability to fly.

This doesn’t flip the break-even calculation on its own. But for a buyer comparing a new $25 million jet against a pre-owned one at $15 million, the downtime differential can narrow the apparent savings. The lower sticker price carries a hidden AOG tax.

California and New York Tax Insiders Know to Model

State tax can add seven figures to the purchase price, and the rules are state-specific. California applies use tax to any aircraft purchased for use in California when sales tax wasn’t paid to a California dealer. Buy an aircraft through an out-of-state entity and base it in Van Nuys, and the CDTFA will want its cut.

New York takes a different approach. It can impose a 4% state use-tax portion plus a local portion of 2.75% to 4.5% when the aircraft is flown into or out of New York and is based in the owner’s county. A Manhattan-based buyer flying a jet into Westchester could face a combined rate above 8%.

These are recurring costs, not just closing costs, because personal property tax in many jurisdictions applies annually to aircraft. The effective cost isn’t in the brochure.

The Real Math: How the Industry Prices Utilization

The numbers behind the threshold come from the people who track this for a living. NBAA’s own rules of thumb had whole ownership becoming viable above 175 flight hours per year. Its fuller guidance raises that to 250 hours as the point where buying is generally a good option. The gap reflects the difference between minimum viability and sensible decision-making.

Context helps. A traditional flight department averages about 430 hours per year. Fractional operators push their aircraft to 1,000 to 1,200 hours each — because they’re spreading fixed costs across multiple owners. That’s the entire point: the fractional model works by achieving utilization that an individual owner almost never matches.

What never makes it into these comparisons is a clean case study of an owner losing money on the sale. The data exists only in aggregate. Nobody publishes their mistake.
