Aircraft loan calculator
Estimate an aircraft loan payment, cash needed, interest and the balance due at a balloon or maturity date. Use the full amortization term when the loan has no earlier balloon.
How to calculate an aircraft loan payment
The scheduled payment uses the standard fixed-rate amortization formula:
Payment = P × r(1 + r)n ÷ ((1 + r)n − 1)
P is the amount financed, r is the monthly interest rate and n is the number of months in the amortization term. If APR is 0%, payment equals principal divided by the number of months. The amount financed here is purchase price minus down payment plus entered tax and financed acquisition costs.
Amortization term versus balloon maturity
The amortization term controls the scheduled payment. The balloon or maturity field controls when the remaining principal becomes due. For example, a 20-year amortization with a 10-year maturity uses a 20-year payment but reports the unpaid balance after 10 years. Set both fields to the same value for a fully amortizing estimate with no earlier balloon.
This distinction matters because a comparatively low monthly payment can coexist with a large balance due at maturity. Refinancing that balance is not guaranteed, so compare the balloon amount as carefully as the payment.
What to include for an aircraft purchase
- Financed costs: enter only eligible costs that will be added to the loan principal.
- Cash costs: include inspection, escrow, title, legal or other acquisition costs paid outside the loan.
- Tax: enter the rate that applies to the transaction and location; the calculator does not decide sales or use-tax treatment.
- Ownership costs: keep insurance, hangar or tie-down, fuel, maintenance, inspections, reserves and training separate from the loan payment.
Checked example
For a $350,000 aircraft, 20% down, no entered tax, $5,000 of financed acquisition costs, 7.25% APR, 20-year amortization and a 10-year maturity, the amount financed is $285,000. The scheduled payment is about $2,253 per month and the estimated balloon balance after 120 payments is about $191,870. Entering $5,000 of cash costs makes the estimated initial cash requirement $75,000.
Limits of this estimate
This planning tool assumes a fixed rate and monthly payments. It does not model variable rates, interest-only periods, irregular payments, lender-specific day-count rules, late charges, prepayment penalties, insurance requirements or tax advice. Extra principal is applied after scheduled interest in the simulation. A lender’s documents and closing statement control the actual payment and payoff amount.
Frequently asked questions
Are aircraft loan and aircraft finance calculators different?
They generally describe the same calculation. This page covers aircraft, airplane and aviation finance wording in one tool instead of creating duplicate synonym pages.
Why can the financed amount exceed the purchase price?
Entered tax and financed acquisition costs increase principal. The financed amount-to-price ratio is therefore a planning ratio, not a lender’s formal loan-to-value calculation.
Does extra principal reduce the balloon?
Yes. The simulation adds the entered extra amount to each scheduled payment and applies it to principal. If the balance reaches zero before maturity, the balloon is $0.
Can I use this for helicopters or other aircraft?
Yes, if the proposed financing is a fixed-rate monthly installment loan. Enter the actual quote assumptions and treat the result as an estimate.
