Piper Super Cub Cost of Ownership: PA-18 Backcountry Budget, Fabric Reserve and Loan Line
This is the annual budget for a certified Piper PA-18 Super Cub, the two-seat tube-and-fabric taildragger that backcountry pilots have flown since 1949. It is built around the 150 hp PA-18-150, covers what fabric, tailwheel flying and modifications add, and shows how the airplane's age changes the loan.
What are you budgeting for?
The PA-18 has a steel-tube fuselage and fabric-covered wings and fuselage, tandem seating, a tailwheel and, on the PA-18-150, a 150 hp Lycoming O-320 with a fixed-pitch propeller. Earlier PA-18s used smaller engines, and many airplanes now carry 180 hp conversions, big tires, STOL modifications, floats or skis. Piper built the PA-18 over several decades, so the fleet runs from 1950s airplanes to much later ones. Specs and generated payment examples are on the PA-18 Super Cub model page.
Prices are hedged. Our model data lists typical Super Cub prices of about $45,000 to $150,000; rebuilt and heavily modified backcountry airplanes can ask considerably more. We could not verify model-specific sold data, so check Vref or Aircraft Bluebook and ask for sold comparables, and remember that modifications only add value when the paperwork is in order. This page uses $130,000 as an illustration. Experimental Super Cub replicas and newer Cub-style designs are separate budgets; see financing experimental aircraft for how homebuilt versions are underwritten.
Super Cub annual budget at 50, 100 and 200 hours
Fixed costs
| Item | Per year | Basis |
|---|---|---|
| Insurance (hull + liability) | $2,000 | Assumption; experienced tailwheel pilot, about $130,000 hull |
| Hangar | $3,000 | Assumption ($250/month); protects the fabric |
| Annual inspection (before squawks) | $1,800 | Assumption; shop that knows tube-and-fabric airframes |
| Subscriptions, EFB, misc. | $500 | Charts or EFB, small parts |
| Total fixed | $7,300 |
Hourly operating costs
| Item | Per flight hour | Basis |
|---|---|---|
| Fuel | $61.54 | 8.5 gph × $7.24/gal 100LL |
| Oil and filters | $2.00 | Four-cylinder oil changes and top-ups |
| Engine reserve | $16.00 | Assumed $32,000 O-320 overhaul ÷ 2,000 hr |
| Propeller reserve | $1.00 | Fixed-pitch propeller |
| Fabric reserve | $6.00 | Saving toward an eventual recover of wings and fuselage |
| Unscheduled maintenance reserve | $15.00 | Gear shocks or bungees, tailwheel, brakes, big tires, magnetos |
| Total hourly | $101.54 |
Total by utilization
| Hours / yr | Operating cost | Per hour | With loan | Per hour with loan |
|---|---|---|---|---|
| 50 | $12,377 | $248 | $23,263 | $465 |
| 100 | $17,454 | $175 | $28,340 | $283 |
| 200 | $27,608 | $138 | $38,494 | $192 |
Every line is an assumption; replace it with local quotes. The engine reserve uses Lycoming's 2,000-hour TBO for the O-320 family (Service Instruction 1009); Cubs that fly little should also watch calendar time and corrosion. See understanding SMOH and TBO.
Fabric, tubing and backcountry wear
- Fabric recover. Wings and fuselage are fabric-covered. When the fabric fails strength testing, recovering is a large one-time bill; the $6 per hour reserve spreads it. Ask for the date and system of the last cover.
- Tube corrosion. Moisture collects in the lower fuselage tubes and around the tail. Inspect them on the pre-buy, especially on airplanes kept outside or flown on floats.
- Gear and tailwheel. Rough strips wear the landing gear shock system, tailwheel, brakes and tires. Big tundra-style tires cost more to replace.
- Floats and skis. Seasonal changeovers cost labor, floats need their own inspections, and saltwater adds corrosion work.
- Storage. A hangar protects the fabric from sun, which is why we budget one rather than a tie-down.

Modifications and 180 hp conversions
Many Super Cubs have been modified under STCs or field approvals. The most common budget-changer is a 180 hp engine conversion: on our assumptions (10 gph and a $38,000 overhaul over 2,000 hours), it costs about $14 more per hour than a stock 150 hp airplane, or $1,386 over 100 hours, in exchange for better climb and short-field margin. Big tires, STOL kits, extended baggage and gross-weight increases each carry their own paperwork, and some affect the stall speed that decides sport pilot eligibility. Check every Form 337 and STC before you buy, because appraisers and lenders will.
Insurance and sport pilot eligibility
We budget $2,000 a year as an assumption for an experienced tailwheel pilot. There is no Super Cub benchmark in our verified sources; tailwheel time, time in type, the hull value and float or off-airport use all drive the quote, and insurers typically set tailwheel-time minimums. See insurance requirements.
The PA-18-150 grosses more than the former light-sport weight limit, so sport pilots could not fly it before MOSAIC. Since October 22, 2025, a sport pilot may fly any airplane with a clean stall speed (VS1) of 59 knots CAS or less at maximum certificated takeoff weight, with up to four seats and one passenger. A given Super Cub may qualify; check its POH, including any STC that changes gross weight, and keep the documentation. See the MOSAIC light sport financing guide. A certified Super Cub is still financed as a certified piston.
Where does the loan payment fit?
As of September 2026, piston aircraft loan rates quoted by major aviation lenders generally start around 7% for well-qualified borrowers and run to roughly 10%. AOPA's guidelines call for 15% down on post-1960 singles and 20% on aircraft built before 1960, and they allow 20-year terms only on loans of $75,000 or more. At $130,000:
| Airplane built | Down payment | Loan | 20 years | 15 years |
|---|---|---|---|---|
| 1960 or later | 15% | $110,500 | $907 | $1,040 |
| Before 1960 | 20% | $104,000 | $854 | $979 |
| Term | 6.99% APR | 7.75% APR | 9.99% APR |
|---|---|---|---|
| 15 years (180 mo) | $993/mo | $1,040/mo | $1,187/mo |
| 20 years (240 mo) | $856/mo | $907/mo | $1,066/mo |
Loan amount $110,500. Principal and interest only; excludes insurance, taxes and fees. Illustrative, not a quote.
Older airplanes may also be offered shorter terms. See aircraft loan requirements and how age and condition affect financing.

Frequently asked questions
How much does a Super Cub cost to own per year?
On this page's planning assumptions, a PA-18-150 Super Cub flown 100 hours a year costs about $17,454 to operate before financing, or $175 per hour. A loan on a $130,000 example (15% down, 7.75%, 20 years) adds about $10,886 a year. The fabric and unscheduled reserves are set for backcountry use; paved-runway owners may spend less.
How much fuel does a Super Cub burn?
We plan on 8.5 gallons per hour for the 150 hp Lycoming O-320, about $62 per hour at $7.24 a gallon for 100LL (AirNav national average, September 2026). Big tires, floats and slow-flight work raise real-world burn, and 180 hp conversions burn more; we plan on 10 gph for those.
Can a sport pilot fly a Super Cub?
Possibly. A PA-18-150 grosses more than the former light-sport weight limit, so it did not qualify before. Since October 22, 2025, a sport pilot may fly any airplane with a clean stall speed (VS1) of 59 knots CAS or less at maximum certificated takeoff weight, up to four seats and one passenger. A given Super Cub may qualify; check its POH, including any STC changes to gross weight.
How much down payment does a Super Cub loan need?
It depends on the year. AOPA's guidelines call for 15% down on post-1960 singles and 20% on aircraft built before 1960, and Super Cubs span both. At $130,000, 15% down leaves $110,500 (about $907 a month over 20 years at 7.75%), while 20% down leaves $104,000 (about $854 a month). Older airplanes may also get shorter terms.
Why does a Super Cub budget include a fabric reserve?
The Super Cub's steel-tube fuselage and wings are fabric-covered. Fabric eventually fails strength testing and needs recovering, which is a large one-time bill, and the tubing underneath needs corrosion checks. Setting aside $6 per hour spreads that cost. Ask for the date and method of the last cover and have the fabric tested on the pre-buy.
Do modifications change a Super Cub's ownership costs?
Yes. Big tires, STOL kits, extended baggage, float fittings and 180 hp engine conversions are common, each under an STC or field approval. They can raise value and capability, but they also change fuel burn, maintenance and sometimes insurance. Lenders and appraisers will want the paperwork for every change, so check the Form 337s and STCs before you buy.
