What a Robinson R44 Raven II costs per hour
The Robinson R44 Raven II is a piston helicopter with 3 seats, burning 15 gallons of 100LL avgas an hour. In our estimate it costs $333 for every hour it flies and $25,368 a year whether it flies or not. Spread over 200 hours a year, that is about $460 a flight hour; over 100 hours, $587; over 400, $396.
The estimate assumes the owner flies it, so there is no pilot salary in it. Hiring a pilot adds about $120,808 a year; the calculator below has a switch for that. The largest single cost at 200 hours is fuel cost, at $22,200 a year.

How we estimate these costs
Every aircraft on our operating cost calculator is costed the same way: fixed costs a year plus a cost per flight hour, from public inputs. Crew pay comes from the U.S. Bureau of Labor Statistics, hangar rates from published airport schedules, insurance from a broker's published guidance, fuel from our fuel price data, and the fuel burn, engine overhaul interval and price from Robinson Helicopter Company. Lines marked “estimate” are the midpoint of a stated range for piston helicopters, not a quote. Nothing here comes from another cost calculator or a broker's budgets.
- Not included: the purchase price, financing, depreciation, sales tax, upgrades and paint or interior work, and any rental or charter income.
- What moves it most: hours flown (fixed costs spread thinner), the fuel price, where it is hangared, the pilot's experience (insurance) and the aircraft's age (maintenance).
