The headline is the monthly principal & interest on price minus down plus financed fees. Tax, registration, insurance, marina slips, and winter storage are not in the payment.
Quick reference: boat / marine lending
Why boat notes often look different from car loans.
| Item | Notes |
|---|---|
| Collateral | Boats depreciate and survey/condition matter more than VIN alone |
| Down payment | Often higher than auto — used boats especially |
| Term length | Can stretch longer than cars on newer / higher-value boats |
| Extras | Trailer, electronics, and taxes may be separate cash needs |
This tool amortizes a fixed-rate note only. Variable marine rates and balloon structures are not modeled.
How the estimate is built
Loan = price × (1 − down%) + fees. Monthly payment uses standard amortization: PMT(loan, APR, term months). Total interest = payment × months − loan.
Example scenario
A $45,000 boat with 20% down and $800 financed fees at 8.5% for 10 years finances about $36,800 and lands in the mid–$400s per month in this model.
FAQ
Is a boat loan the same as an auto loan?
Not always. Many marine lenders use different underwriting, down-payment norms, and terms than car notes — this calculator only does payment math on the numbers you enter.
Does the payment include insurance or slip fees?
No. Boat insurance, marina slips, haul-out, and winter storage sit outside principal & interest.
New vs used boat rates?
Used boats often see shorter max terms or higher rates. Plug the quote you actually receive.
