Owning the machine is a business: crew, berth or hangar, insurance, depreciation, and capital standing idle between trips. Whether you want to be in that business depends on one number — how much you actually use it. This instrument prices all three doors at your real utilisation and prints the break-even where ownership starts to pencil.
Sets the unit of use. Aircraft are metered in flight hours; yachts in days aboard.
The machine, delivered and fitted.
Crew, hangar or berth, insurance, management, scheduled maintenance. The 10% rule is a fair opening bid for both machines.
Fuel, handling, consumables — what one more hour or day directly burns.
Last year's real number. Ambition is not utilisation.
All-in retail for the equivalent machine.
The share purchase for a programme covering your usage.
Straight-line on the machine's value. Fractional shares wear the same, plus a resale haircut.

Charter's hidden line is availability: peak weeks, repositioning legs and short-notice premiums can add 20–30% to the rate you entered. Owners never wait; that convenience is what the fixed costs buy.
With yachts, the crew is the product. A badly run boat at half the cost is not half the boat — budget the fixed line generously or the comparison flatters ownership.
Fractional exits are soft. Shares resell into a thin market at the operator's mercy; the model's 30% haircut on residual is a convention, and reality has been known to undercut it.
Everything below is calculated from your inputs except depreciation and market return, which are assumptions you control. All flows are future-valued to the horizon at the market rate, so the three doors are directly comparable.
g = (1+r)^n ann = (g − 1)/r
own_cost = P·g + (fixed + var·use)·ann − P·(1−dep)^n
fraction_cost = B·g + (12·mgmt + rate_f·use)·ann − 0.7·B·(1−dep)^n
charter_cost = charter_rate · use · ann
break_even_use = (P·(r + dep) + fixed) / (charter_rate − var)
The gauge reads your usage against the ownership break-even, parity at 100%. Below roughly 55% of break-even the house says charter; between there and parity is fraction territory; past parity, ownership pencils. The verdict names the cheapest door outright and flags margins under 10% as a line-ball.
Limitations. Charter assumes rates hold across the horizon; fractional programmes differ wildly in fees and exit terms — read yours, then correct the inputs. Crew quality, availability and the pleasure of the thing being yours are outside the arithmetic, where they belong.
