Enter the loan amount, interest rate, and term to calculate your monthly boat loan payment and total interest paid.
How to Use the Boat Loan Calculator
Just three fields — amount, rate, term — mirror those into the calculator and the monthly payment and total interest populate immediately.
Boat financing runs on the same fixed-payment math as any other secured loan, just usually over a longer term than a car loan and often at a somewhat higher rate, since lenders treat marine collateral as riskier and harder to resell than a car.
M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]Enter the amount you're financing, the rate your lender quoted, and the term in years to get the monthly payment along with total interest over the life of the loan. There's no assumed rate or term here — marine lending terms vary widely by lender, loan size, and whether the boat is new or used, so plug in your actual quote rather than a guess.
