How boat finance works
A boat loan is normally a secured consumer loan, with the vessel itself as the security. Because there is an asset behind the loan, secured marine finance is generally priced differently from an unsecured personal loan — which is one reason it is worth modelling the numbers before you start shopping.
Alpha390 Finance arranges boat finance across a panel of bank and non-bank lenders. What you actually pay depends on the vessel, the term, your deposit and your circumstances, so treat the figure above as a starting point rather than an answer.
What changes the number
The vessel and its age
Lenders take a view on the boat as well as the borrower. Older hulls and older engines can attract shorter maximum terms or a different rate, and some lenders set an age limit at the end of the loan rather than at the start — worth checking before you commit to a long term on an older boat.
New, used, dealer or private sale
Buying privately is common in the marine market and is generally financeable, but the process differs from a dealer purchase. Expect the lender to want the vessel properly identified and any existing finance on it cleared before settlement.
Whether the engine is part of the purchase
Repowering, or buying a hull and engine separately, changes what is being financed. If the engine is the main event, see boat repower loans.
Survey and insurance
For larger or older vessels, lenders may ask for a marine survey, and comprehensive insurance is commonly a condition of a secured marine loan. Neither is a cost the calculator captures.
Your own position
Income, existing commitments and credit history all feed into the rate you are offered, as they do on any consumer loan.
A word on balloons
The calculator defaults the balloon to 0%, and for most private boat buyers that is the right starting point. A balloon (or residual) leaves a lump sum owing at the end of the term. It lowers the regular repayment, but you pay more interest overall and you still have to deal with the lump sum — pay it out, refinance it, or sell the boat. Balloons are far more common on business-use asset finance than on recreational marine lending. Move the slider if you want to see the trade-off; leave it at zero if you simply want to own the boat outright at the end.
A worked example
A $45,000 boat loan with no deposit, over five years, at an indicative 9.5% p.a. and no balloon returns a monthly repayment of about $945, with total interest of roughly $11,700 across the term. Change any input and the figures move — that is the point of the tool. These are illustrative figures produced by the calculator, not a quote, and they exclude fees, charges and government costs.
What the calculator does not include
Fees and charges, government costs, insurance premiums, mooring or berth costs, registration, servicing, antifouling and running costs. It assumes a fixed rate held for the full term. Your actual repayment will differ.
Ready for a real number?
An estimate is useful for narrowing the field. A lender-checked repayment needs a short conversation about the vessel and your circumstances.

Boat finance calculator FAQs
How accurate is this boat finance calculator?
It is a close estimate using a standard amortised-loan formula on the figures you enter. It assumes a fixed rate for the full term and excludes fees, charges and government costs. Your actual repayment depends on the lender, the vessel and your circumstances.
How long can a boat loan run?
Marine loan terms commonly run up to seven years, which is why the calculator caps the term there. Some lenders shorten the maximum term for older vessels, so the age of the boat can affect what is available to you.
Do I need a deposit for a boat loan?
Deposit requirements vary by lender and by vessel. A deposit or trade-in reduces the amount financed and therefore the repayment. Set the deposit to $0 in the calculator to see the no-deposit position.
Can I finance a boat bought privately?
Private-sale marine purchases are common and generally financeable, though the process differs from a dealer purchase. Lenders will want the vessel properly identified and any existing finance on it cleared before settlement.
Should I use a balloon on a boat loan?
Balloons are more common on business-use asset finance than on recreational boat loans. A balloon lowers the regular repayment but increases total interest and leaves a lump sum to deal with at the end of the term. The calculator defaults to zero for that reason.
Does using this calculator affect my credit score?
No. It runs entirely in your browser, does not check your credit file and does not lodge an application. A credit check only happens later, with your consent, if you formally apply.
