|---|---|---|
| Boat purchase price | $75,000 | Before taxes, fees, and optional add-ons |
| Down payment | $15,000 | 20.0% of purchase price |
| Amount financed | $60,000 | Purchase price minus down payment |

| Estimated monthly ownership cost | $1,346 | Payment plus entered insurance, storage, and maintenance |
| Total interest | $38,285 | Over 180 monthly payments |
Formula and Method
| Item | Formula | Use |
|---|---|---|
| Amount financed | boat price - down payment | Sets the principal used in the payment formula |
| Monthly payment | P x [r(1+r)^n] / [(1+r)^n - 1] | Estimates principal-and-interest payment on an amortized loan |
| Total interest | (monthly payment x number of payments) - amount financed | Shows the finance charge implied by the entered APR and term |
| Ownership estimate | loan payment + insurance + storage + maintenance | Compares the loan payment with a broader monthly boat budget |
In the payment formula, P is the amount financed, r is the monthly rate, and n is the number of monthly payments.
Term Comparison
| Term | Monthly payment | Total interest | Total payments |
|---|---|---|---|
| 10 years | $703 | $24,342 | $84,342 |
| 15 years | $546 | $38,285 | $98,285 |
| 20 years | $472 | $53,378 | $113,378 |
Worked example: financing $60,000 at 7.2% APR for 15 years creates a $546 monthly payment and about $38,285 of interest before taxes, fees, and optional products.
How to Compare Boat Loan Offers
Do not compare offers by monthly payment alone. The same payment can hide a longer term, a higher total interest cost, a larger amount financed, or optional products rolled into the loan.
A practical comparison packet includes the cash price, taxes and fees, down payment, amount financed, APR, term, monthly payment, total of payments, prepayment rules, and required insurance.
If two offers have different fees, compare APR to APR and verify which fees are included. If you only compare an interest rate against an APR, the cheaper-looking offer may not actually be cheaper.

FAQ
What does a boat loan calculator estimate?
A boat loan calculator estimates the principal-and-interest payment for an amortized loan using the amount financed, APR, and loan term. This page also adds optional monthly insurance, storage, and maintenance estimates so you can compare payment-only cost with a broader ownership budget.
Should I enter APR or interest rate?
Use APR when you are comparing loan offers because APR can include interest plus certain loan fees. If a lender only gives an interest rate, the payment estimate can still be useful, but it may not represent the full cost of credit.
How does a longer boat loan term affect cost?
A longer term usually lowers the monthly payment but increases the number of payments, which can raise total interest. The scenario table shows the same loan over shorter and longer terms so you can see that tradeoff.
Does this calculator include insurance, storage, fuel, or maintenance?
The loan payment itself includes only principal and interest. The ownership estimate adds the monthly insurance, storage, and maintenance amounts you enter. Fuel, registration, taxes, marina fees, repairs, and lender fees are not automatically included unless you add them into one of the monthly cost fields.
Is the result a lender quote?
No. This calculator is an educational worksheet. A lender quote can differ because of credit history, down payment, boat age and condition, taxes, fees, collateral rules, dealer products, and underwriting requirements.
What documents should I compare before signing a boat loan?
Compare the amount financed, APR, interest rate, loan term, monthly payment, total of payments, fees, prepayment terms, insurance requirements, and any optional products. Use the lender disclosure and sales contract as the final source of truth.
