A Boat Loan Calculator estimates the monthly payment, total interest and total cost of financing a new or used boat. It takes the boat price, your down payment (in dollars or as a percent), trade-in value and sales tax into account, then applies your loan rate and term. It helps buyers set a realistic budget before talking to a dealer or lender.
How to use it
- Enter the boat price.
- Enter your down payment as a dollar amount or a percentage of the price.
- Enter any trade-in value and your sales tax rate.
- Enter the interest rate (APR) and loan term in years.
- Click Calculate to see the monthly payment, amount financed, total interest, total cost and an amortization schedule.
Boat loan formula
Amount financed = Price + Sales tax − Down payment − Trade-in value
M = P × r(1 + r)^n ÷ ((1 + r)^n − 1)
where M is the monthly payment, P is the amount financed, r is the monthly rate (APR ÷ 12) and n is the number of months.
Example
Financing $40,000 at 8% for 10 years costs about $485.31 a month, with about $18,237 in total interest. Stretching to 15 years lowers the payment to about $382.26 but raises interest to about $28,807.
What affects your boat loan rate?
Lenders set boat loan rates using your credit score, the loan amount, the term, the age and type of boat and the size of your down payment. Longer terms are common for larger boats, which keeps the payment lower but adds a lot of interest, as the example shows. Compare offers by APR and total cost.
Tips: budget for the full cost of owning a boat
- Add insurance, fuel, maintenance, storage or slip fees, registration and safety equipment to the monthly payment.
- A bigger down payment lowers the loan and interest, but keep cash for those running costs.
- Check whether your state charges sales or use tax on boats and whether it applies to the price before or after a trade-in.
- Get a marine survey on a used boat before you buy.
