Airplane Loan Terms Explained: Term Length, Down Payment and Balloon
Airplane loan terms come down to four numbers: term length, amortization, down payment and any balloon. AOPA Aviation Finance lists single-engine piston loans at 5 to 20 years with at least 15% down on aircraft newer than 1960, piston twins at 10 to 15 years with 15% to 30% down, and turbine loans at a 15-year amortization with a 5-year term. When the term is shorter than the amortization, a balloon is due at the end.
Key takeaways
- Term is how long the loan runs; amortization is the schedule the payment is calculated on. When amortization is longer than the term, a balloon is left at maturity.
- AOPA Aviation Finance lists 5 to 20 year terms for single-engine piston loans, with 20 years only on loans of $75,000 and above.
- Down payments commonly start at 15% for piston aircraft and rise with age and complexity; some turbine loans go as low as 10% down, per AOPA Aviation Finance.
- A longer term or a balloon lowers the payment but raises total interest, so compare both numbers.
- Commercial use such as Part 135 charter usually brings shorter terms, lower advance rates and hour limits.
What are the main terms on an airplane loan?
Every airplane loan is defined by four numbers: the term, the amortization, the down payment and any balloon. The interest rate sits alongside them, but these four decide how big the payment is, how fast you build equity and what is still owed when the loan ends.
- Term: how long the loan runs before it must be repaid in full.
- Amortization: the period the payment is calculated over. It can match the term or be longer.
- Down payment: the cash you put in at closing. The rest is the amount financed, and lenders often express it as loan-to-value.
- Balloon: any balance left at the end of the term because the amortization was longer than the term, or because the loan was written with a set residual.
Lenders set each one based on the aircraft, its age and condition, the loan size, the borrower and how the aircraft will be used. The aircraft loan calculator lets you change each number and watch the payment move.
How long can you finance an airplane?
It depends mostly on the aircraft class and age. AOPA Aviation Finance publishes these ranges for its lending programs:
| Aircraft | Term | Down payment |
|---|---|---|
| Single-engine piston | 5 to 20 years (20 years only on loans of $75,000 and above) | At least 15% on aircraft newer than 1960, 20% for older aircraft |
| Multi-engine piston | Maximum 10 to 15 years | 15% to 30%, depending on age |
| Turbine and turboprop | 15-year amortization with a 5-year term, as standard | Could be as low as 10%, depending on the aircraft |
These are one lender network's published figures, not universal rules, and they change. A separate AOPA Aviation Finance article from May 2024 described terms of 15 to 20 years for loans of $200,000 to $350,000, with rates valid only as of April 2024. Treat any published rate as a dated snapshot and ask for current written quotes.
Older aircraft and higher-time engines usually mean shorter terms, because lenders want the loan paid down faster than the aircraft loses value. Our guide to financing a used aircraft explains the age, airframe and engine-time limits lenders use.
How much down payment do lenders want?
For most piston aircraft the starting point is 15%, and it rises for older aircraft, twins and anything harder to resell. AOPA Aviation Finance also notes that on aircraft priced above about $150,000, a lower loan-to-value can lower the rate, while at or under $150,000 a bigger down payment will not change the rate. So on larger aircraft, extra cash down can buy both a smaller loan and cheaper money.
Turbine loans can go lower, with AOPA Aviation Finance describing down payments that could be as low as 10% depending on the aircraft. The down payment guide breaks this down by aircraft class and explains how lenders pick the value they lend against.
What is the difference between term and amortization?
The term is when the loan ends. The amortization is how the payment is sized. When the two match, the loan pays to zero. When the amortization is longer, the payment is lower but a balloon is due at maturity.
The standard turbine structure AOPA Aviation Finance describes, a 5-year term on a 15-year amortization, is the classic example. Payments for five years are sized as if the loan ran fifteen, so after five years most of the original balance is still owed. Borrowers usually pay that balloon by refinancing, selling the aircraft or paying cash. That works well when the aircraft holds value and credit is available at maturity, and badly when either is not true. Our article on balloon payments on aircraft loans walks through both cases.
Worked example: the same loan on four structures
These numbers are hypothetical and only show the math. Suppose an operator finances $300,000 at 7.0% with monthly payments and compares four structures.
| Structure | Monthly payment | Total interest | Owed at the end |
|---|---|---|---|
| 10-year term, fully amortizing | about $3,483 | about $118,000 | $0 |
| 15-year term, fully amortizing | about $2,696 | about $185,400 | $0 |
| 20-year term, fully amortizing | about $2,326 | about $258,200 | $0 |
| 15-year term with a $60,000 balloon | about $2,507 | about $211,300 | $60,000 |
Stretching from 10 to 20 years cuts the payment by about $1,157 a month but more than doubles the interest. The balloon version sits in between: a lower payment than the plain 15-year loan, more interest, and a $60,000 bill at the end. None is right in the abstract. The question is which trade-off fits your cash flow and how long you will keep the aircraft. Run your own numbers in the aircraft loan calculator.
How does commercial use change the terms?
Flying an aircraft for hire changes how lenders see it. AvBuyer reports that lenders view Part 135 charter use as heavier wear that can lower residual value, and that terms are likely to be materially different from Part 91: typically shorter terms, higher rates, lower advance rates and possibly higher down payments. It also reports that lenders may cap annual hours, require extra principal payments if the aircraft flies more than allowed, and require an engine maintenance program.
Flight schools face similar questions about utilization, and lenders will ask about annual hours per aircraft and the maintenance program. See financing a Part 135 charter aircraft and flight school aircraft financing for what those lenders look at.
Which other loan terms should you read closely?
The payment is only part of a loan agreement. Before signing, check:
- Fixed or floating rate, and when a floating rate can reset.
- Prepayment charges, which can make an early sale or refinance expensive.
- Use restrictions, such as limits on charter, leasing, annual hours or where the aircraft is based.
- Insurance and maintenance covenants, including any engine program requirement.
- Guarantees, especially when the borrower is a business entity.
- Balloon refinancing: whether the lender commits to anything at maturity. Usually it does not.
Two loans with the same rate can cost very different amounts once these terms are counted. The aircraft loan interest rate guide explains how to line quotes up fairly.
How do you choose the right terms?
- Start with how long you expect to keep the aircraft. Avoid a balloon that falls due before you plan to sell unless you are confident you can refinance it.
- Set the payment the operation can carry in a slow month, not an average one.
- Price at least two down payment levels, especially on aircraft above about $150,000, where it may change the rate.
- Compare total interest and the balance owed at each year end, not only the monthly payment.
- Tell every lender the same facts about use and hours, so the quotes are comparable.

Frequently asked questions
How long can you finance an airplane?
For single-engine piston aircraft, AOPA Aviation Finance lists terms of 5 to 20 years, with 20 years available on loans of $75,000 and above. It lists maximum terms of 10 to 15 years for piston twins, and a 15-year amortization with a 5-year term as standard for turbine aircraft.
What is the minimum down payment on an airplane loan?
AOPA Aviation Finance lists a 15% minimum down payment on single-engine aircraft newer than 1960 and 20% for older aircraft, and 15% to 30% for multi-engine aircraft depending on age. Lenders set the final figure on the specific aircraft and borrower.
What is the difference between term and amortization?
The term is when the loan ends. Amortization is the period used to calculate the payment. A 5-year term on a 15-year amortization has payments sized as if the loan ran 15 years, so most of the balance is still owed as a balloon after 5 years.
Is a 20-year airplane loan a good idea?
It gives the lowest payment, but you pay more interest and build equity slowly, so the balance can stay close to the aircraft value for years. It suits buyers who will keep the aircraft a long time and value cash flow over total cost.
Do charter aircraft get the same loan terms?
Usually not. AvBuyer reports that lenders financing Part 135 aircraft generally use shorter terms, higher rates and lower advance rates, and may cap annual hours.
