Using the Boat Loan Calculator
Calculate the loan payment first, then build a separate allowance for storage, insurance, maintenance and fuel. A seasonal pattern of use does not usually change the monthly amount owed to the lender.

Method and assumptions
Fully amortizing loan with equal end-of-month payments, monthly interest and no fees, taxes, insurance or variable-rate changes. All amounts use the same currency.
Compare the whole borrowing commitment
When comparing loan scenarios, change one assumption at a time. First compare terms at the same rate and balance, then compare rates over the same term. This makes it easier to see why the monthly payment changes. Keep any upfront costs alongside the result so that a lower installment does not hide a more expensive agreement.
Common question
Can this estimate a balloon-payment boat loan?
No. It assumes the entire balance is repaid through equal monthly installments. A loan with a balloon payment needs the final lump sum included in a separate calculation.
