How an aircraft loan payment is calculated
A fixed-rate airplane loan is amortized just like a car or home loan. If you borrow a principal PV at a monthly rate r (the APR divided by 12) for n months, and a balloon B is due at the end (use 0 if there is none), the monthly payment is
M = (PV − B × (1+r)−n) × r / (1 − (1+r)−n)
Each month, interest is charged on the remaining balance and the rest of the payment reduces principal. Total interest is everything you pay — the payments plus the balloon — minus the amount you originally borrowed.
Balloon payments
Aviation lenders sometimes offer a shorter term with a balloon: you make lower payments for 5, 7, or 10 years, then refinance, sell, or write a check for what is left. The balloon is not free money; it is principal you still owe. This page shows that remaining balance on the last row of the schedule.
Affordability
The affordability mode inverts the same formula. You type a monthly payment you can live with, a down payment, a rate, and a term, and the calculator reports the maximum purchase price those payments will support. A lender will also look at credit, the airplane’s age and engine times, and insurance, so treat the result as a ceiling, not an approval.
Worked example
A $250,000 airplane, 20% down ($50,000), $200,000 financed at 7.25% for 20 years, no balloon:
- The monthly payment is about $1,579.
- Over 20 years you pay about $179,000 of interest, and $379,000 in total payments, plus the $50,000 you put down.
- A $50,000 balloon on the same loan lowers the monthly payment (because you are not amortizing that $50,000) and leaves $50,000 due at month 240.

Frequently asked questions
How is an aircraft loan payment calculated?
It uses standard fixed-rate amortization. The payment is set so the balance reaches the balloon — or zero — at the end of the term. Total interest is payments plus any balloon, minus the amount borrowed.
What is a balloon payment on an airplane loan?
A lump of principal still owed at the end of the term. It lowers the monthly payment. You then refinance, sell, or pay it in cash.
How much airplane can I afford?
Work backward from a monthly payment, down payment, rate, term, and any balloon. The result is a maximum price, not a lender’s approval.
Are aircraft loan rates different from mortgage rates?
Often, yes. Airplanes are specialized collateral and terms are commonly 10–20 years. Use a quote from an aviation lender in this form.
