About the Boat Loan Calculator

Enter the purchase price, your down payment, the rate and the term to get the monthly payment and the total interest on a boat loan. Marine finance runs on much longer terms than car finance, often fifteen to twenty years, which changes the arithmetic considerably.

The loan is rarely the largest cost of owning a boat. Mooring or slip fees, winter storage, insurance, haul-out, bottom paint, engine servicing and fuel typically add up to a substantial fraction of the purchase price every year. A common planning figure is ten percent of the value annually, and the calculator includes those fields so the number you compare against your budget is the true cost of ownership rather than just the finance payment.

Key features of the Boat Loan Calculator

Long terms supported

Marine loans run ten to twenty years, which changes the interest arithmetic considerably against a car loan.

Running costs included

Mooring, storage, insurance, servicing and fuel usually exceed the loan payment itself.

True monthly cost

The figure to compare against your budget, rather than the finance payment alone.

Depreciation awareness

A long term against a depreciating asset means a long stretch of negative equity, shown in the schedule.

Down payment modelling

Marine lenders want ten to twenty percent, and more usually buys a better rate.
