| Fixed costs | Per year | How it is worked out |
|---|---|---|
| Crew Salary | $448,220 | 1 captain at $190,440 (BLS 75th percentile, commercial pilots), 1 first officer at $123,220 (BLS median, commercial pilots), plus 43% for benefits and payroll costs (BLS Employer Costs for Employee Compensation, private industry, June 2026).Source: BLS Occupational Employment and Wage Statistics, May 2025 (released May 15, 2026); BLS Employer Costs for Employee Compensation, June 2026 (released September 9, 2026) |
| Crew TrainingEstimate, $40,000 to $80,000 | $60,000 | Recurrent training each year for 2 pilots, at $20,000 to $40,000 per pilot for a medium twin helicopter. CRAFT estimate. |
| HangarEstimate, $27,660 to $78,000 | $52,830 | From Concord-Padgett's large-aircraft hangar rate ($2,305 a month) to an AW139 footprint (55 ft long, 45 ft rotor) at Naples' $1.85 a square foot, with room around it ($6,500): $2,305 to $6,500 a month. Big-city airports cost more, a tie-down much less.Source: Published airport hangar and tie-down rates (Concord-Padgett Regional, City of Concord NC; Naples Airport Authority FY2026) (read October 15, 2026) |
| InsuranceEstimate, $108,000 to $215,000 | $161,500 | Liability of $8,000 to $15,000 a year plus hull cover at 1% to 2% of a hull value of $10,000,000, a typical value for medium twin-engine helicopters, CRAFT estimate (no published price for this model). Liability starts from BWI's published helicopter figure and rises with the higher limits a two-pilot passenger helicopter carries; hull at 1% to 2% of value is a CRAFT estimate, lower as values rise. Midpoints used; pilot experience moves it a lot.Source: BWI Aviation Insurance, "Helicopter insurance cost" (January 28, 2020) |
| ManagementEstimate, $60,000 to $108,000 | $84,000 | A management company's fee of $5,000 to $9,000 a month for a medium twin helicopter (crew, maintenance tracking, compliance and billing). CRAFT estimate.Source: Business Jet Traveler, "Is a management company right for you?" |
| Miscellaneous FixedEstimate, $40,000 to $70,000 | $55,000 | Navigation databases and charts, weather and flight planning, maintenance tracking, connectivity and office costs: $40,000 to $70,000 a year for a medium twin helicopter. CRAFT estimate. |

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 from USDA Forest Service. Lines marked “estimate” are the midpoint of a stated range for medium twin-engine 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).
