What a Gulfstream G450 costs
Indicative mid-2026 market figures. Approximate — not an appraisal of any individual aircraft.
Pre-owned, typical ask
$7–13 million
varies with hours and engine programme
Variable cost per hour
$4,000–5,800
fuel, maintenance reserves, crew trip costs
Operating a Gulfstream G450 costs approximately $4,000–5,800 per flight hour in variable costs — fuel, maintenance reserves, engine programme and crew trip expenses. Fuel alone accounts for roughly $2,470 of that: 380 gallons of Jet-A an hour at $6.50 a gallon. Fixed ownership costs (hangarage, insurance, salaried crew, depreciation) sit on top and roughly double the annual bill.
Acquisition prices are manufacturer list prices for models still in production and typical pre-owned asking ranges otherwise. Hourly figures are variable direct operating cost only; fixed ownership costs are excluded.
