How to calculate boat loan payments
You can change your desired loan amount, term or APR to see different results and decide how boat loan payments fit into your budget.
Loan amount: This is the amount you expect to borrow. Amounts for unsecured loans can be as high as $100,000, while secured boat loans can be over $1 million.
Repayment term: This is how long you think you’ll need to repay the loan. Unsecured loans often have repayment terms of two to seven years; secured boat loan terms can be as long as 20 years. Longer repayment terms typically mean lower monthly payments, but you'll pay more in total interest.
Annual percentage rate: This is the interest rate you expect to get on the loan. Factors that determine your APR on a boat loan include whether it’s a secured or unsecured loan, your creditworthiness, income and existing debts.

Secured vs. unsecured boat loans
Boat loans are either secured or unsecured. With a secured loan, the boat you’re purchasing is collateral for the loan, meaning the lender can take the boat if you stop making payments.
Secured boat loans may require or give you the option to make a down payment, so you’ll borrow less overall. They also tend to have lower APRs than unsecured boat loans and can be easier to qualify for if you have a low credit score.
Though unsecured loans may cost more in interest, they don’t require collateral or a down payment, and borrowers with good or excellent credit (690 FICO or higher) may qualify for a low rate.
Here are average estimated APRs on unsecured personal loans, based on FICO score ranges:

Common questions about boat loans
Where can I get a boat loan?
You can get a boat loan from an online lender, bank or credit union. Banks and credit unions will be more likely to offer secured loans.
You can also get a boat loan through a marine lending specialist, who acts as a broker for the loan. These loans must be secured and typically require a down payment.
How long are boat loans?
Boat loan repayment terms depend on the type of loan and lender you choose. For unsecured loans, borrowers can expect terms ranging from two to seven years. For secured loans, terms can stretch up to 20 years.
How do I apply for a boat loan?
You can apply for a boat loan directly with the lender. Most lenders offer online applications, but you may need to visit a branch to close the loan.
When you apply for the loan, expect to give personal information (including your Social Security number), details on the craft if the loan is secured, and verification documents such as proof of identity, employment and income.
Approval and funding time vary. Online lenders can usually fund a loan quicker than banks and credit unions. They also let you pre-qualify and see estimated interest rates and potential loan terms without affecting your credit score.
