SR22 Operating Cost Estimates
Operating Cost:
A. Fuel - 15 GPH average cruise burn X $2.50/gallon = $37.50
B. Oil 1/6 QPH X 3.50/quart .58
C. Oil Change 100 average cost per change divided by change
Interval of 50 hours 2.00
Routine Maintenance:
As a rule of thumb for initially setting rates, the hourly cost for routine engine (spark plugs and accessories) and airframe (batteries, instruments, tires and brakes) maintenance can be roughly estimated as one half the hourly cost of fuel and oil. Also remember that in a new airplane, these costs will be greatly reduced initially, then will climb up to normal averages after 300-500 hours of use.
D. Engine and Airframe:
Add fuel cost per hour (“A” above) $37.5
- oil cost per hour (“B” above) $ .58 = 38.08
multiply by one-half for routine maintenance cost per hour $19.04
E. Total Direct Operating Cost/ Hour (total A-D) $59.12
OPTIONAL: RESERVES
This creates a “reserve” fund or savings account to prepare the owner for an upcoming major expense- namely an engine and propeller overhaul. Since engine overhauls can be financed separately, or the entire airplane re-financed, many pilots would not consider this savings method a true out of pocket expense. Thus we leave reserves as your option.
F. Estimated Engine Overhaul- full overhaul or factory remanufactured.
$25,000… Divided by engine TBO (time
before overhaul) of 1700 hours. Engine
reserve cost per hour $14.71
G. Estimated Propeller Overhaul- Average three blade overhaul cost of
2,000. Divided by Prop TBO of 2000 hours
Prop reserve cost per hour 1.00
H. Total “reserve” fund allocation per hour $15.71
Fixed Costs (Averages based upon current experience- these can vary widely):
I. Yearly insurance costs $3,500.00
J. Yearly hanger or tie down $3,600.00
K. Annual Inspection Cost $500.00
L. Total Fixed Cost per flight hour:
Total of I-K divided by estimated number of flight hours per year:
1. $7,600.00/ 100 hours/year $76.00/hour
2. $7,600.00/ 250 hours/year $30.40/hour
