The short answer
Most well-qualified buyers put 15–20% down on a piston aircraft, with 20–25%+ common on older airframes, twins, helicopters, or with weaker credit. Turbines and jets typically run 15–20% as well, with larger loans reviewed more closely.
Typical Down Payments by Aircraft Type
| Aircraft | Typical down |
|---|---|
| Piston single (newer) | 15–20% |
| Piston single (older/classic) | 20–25%+ |
| Piston twin | 20%+ |
| Turboprop / jet | 15–20% |
| Helicopter | 20–25% |
These are typical ranges for well-qualified buyers, not guarantees. Weaker credit and older or off-program aircraft push the number up.
Why the Down Payment Matters
Your down payment reduces the lender's risk (lowering your rate), reduces your loan balance (lowering your payment and total interest), and can be the difference between approval and decline on a marginal application. But putting every dollar down ties up cash you may want for reserves and maintenance — match it to your cash position, not just the minimum. Model the trade-offs with our loan calculator.

Related Questions
Can I put less than 15% down?
Sometimes, on a newer airplane with strong credit, but expect a higher rate. Lower down payments increase the lender's risk and your cost.
Does the down-payment source matter?
Yes. Lenders verify the source with bank or brokerage statements, so keep documentation ready. Savings, asset sales, and trade-ins are common.
Is a bigger down payment always better?
It lowers your rate and total interest, but ties up cash you may want for reserves and maintenance. Balance the two.
