Methodology
Every calculator runs in your browser using the formulas on its page. The structure follows AOPA's operating cost method: fixed costs per year plus direct costs per hour, with reserves for maintenance and engine overhaul.
- Fuel prices: AirNav's nationwide 100LL report.
- Storage: published airport hangar and tie-down fee schedules.
- Insurance: published broker quote ranges (BWI, Sunset, FLYING Finance). Our insurance estimator uses calibrated base rates and pilot factors, labeled on that page.
- Maintenance and overhaul: AOPA examples, Flying, engine shop price lists and Lycoming/Continental TBO documents as reported by the sources linked.
Where no source gives a number, we choose a value inside published ranges and label it an assumption. Scope: US small piston airplanes; not jets, turboprops or commercial operations. Last reviewed November 5, 2026.
Estimates only. These results are estimates for planning, not quotes, and not financial, insurance or maintenance advice. Real costs depend on the airplane, the airport, your insurer and your mechanic. Get quotes.
