> The boat loan calculator works out the monthly payment, total interest and total cost of financing a boat from the price, down payment, trade-in, sales tax, interest rate and term – boat loans often run 10–20 years.

## Inputs

- Boat price
- Down payment
- Trade-in value
- Sales tax (%)
- Interest rate (%)
- Loan term (years, months)

## Results

- Loan amount
- Monthly payment
- Total interest
- Total cost
- Estimated yearly ownership cost (10% of price)

## Formula

```
Loan = price + tax − down payment − trade-in
Monthly payment = loan × i ÷ (1 − (1 + i)^−n)
```

## Explanation

Lenders typically want 10–20% down on a boat. Long terms keep payments low but you will pay far more interest – and boats depreciate, so you could owe more than it's worth. Budget for insurance, storage, fuel and maintenance (often 10% of the price per year).

### What each result means

- **Loan amount** = [Boat price]×(1 + [Sales tax]÷100) - [Down payment] - [Trade-in value]
- **Monthly payment** = pmt([Interest rate]÷1200, [Loan term], [Loan amount])
- **Total interest** = [Monthly payment]×[Loan term] - [Loan amount]
- **Total cost** = [Monthly payment]×[Loan term] + [Down payment] + [Trade-in value]
- **Estimated yearly ownership cost (10% of price)** = [Boat price]×0.1
