Long terms cost more interest
RV and boat loans stretch to 15–20 years, which lowers the payment but piles on interest — $62,266 here. A larger down payment or a shorter term cuts it sharply.

The basics
What drives an RV loan payment?
An RV or boat loan is a secured installment loan, like a car loan but longer. Two things set the payment.
price + tax + fees − down − trade
The amount financed
You do not finance the sticker price alone. Sales tax and fees add to it; your down payment and any trade-in subtract. The result is what actually carries interest.
$85,000 → $80,600 financed after $10,000 down
long terms, more interest
The term stretches the cost
RV loans run 10 to 20 years. A long term lowers the monthly payment but adds interest on a depreciating asset — the classic trade-off to weigh.
15 years → $62,266 of interest
Method
How the payment is worked out
Four steps from the price on the lot to the payment and the total cost.
- 1
Work out the amount financed
Add sales tax and fees to the price, then subtract your down payment and any trade-in.
$85,000 + $5,100 + $500 − $10,000 = $80,600 - 2
Set the monthly rate and periods
Divide the annual rate by twelve for i, and multiply the years by twelve for n.
8.5% ÷ 12 · 15 × 12 = 180 - 3
Apply the loan formula
The level-payment formula gives the fixed monthly payment that clears the balance over the term.
M = P·i ÷ (1 − (1 + i)^−n) = $793.70 - 4
Add up the interest and total cost
Total interest is the payments minus the amount financed; total cost adds back your down payment and trade-in.

What this covers
The same math prices most recreational-vehicle purchases.
motorhomes
Class A, B and C RVs
Drivable motorhomes are the priciest RVs, often financed over 15–20 years. The long term makes the total interest the number to watch.
The biggest loans and longest terms
towables
Travel trailers & fifth wheels
Trailers cost less and use shorter terms, but the same formula applies — price plus tax minus down payment, over the term.
Smaller loans, 10–15 years
boats
Boats & personal watercraft
Marine loans work the same way, with rates and terms that also depend on new versus used and the age of the vessel.
Priced just like an RV loan
Reference
What moves your rate
General guidance, not a quote. RV and boat pricing swings on a few factors.
| Factor | Lower rate | Higher rate |
|---|---|---|
| Credit score | Excellent (740+) | Fair or poor |
| New vs used | New unit | Older or used unit |
| Down payment | 20% or more | Little or none |
| Loan term | Shorter term | 15–20 years |
| Loan size | Large, well-secured | Very small loans |
Worth knowing
Five things before you finance
An RV is a lifestyle purchase — go in with the full picture.
it depreciates
Value drops fast
RVs and boats lose value quickly, especially new. A long loan with little down can leave you owing more than it is worth for years.
carrying costs add up
Budget the whole thing
Insurance, storage, maintenance, registration and campground fees can rival the payment. Plan for them before you buy.
a bigger down helps
Put more down
A larger down payment lowers the loan, the rate and the risk of going upside down. Aim for 10–20%.
new vs used
Used costs more to finance
Used units carry higher rates and shorter maximum terms, but a much lower price — often the better overall deal.
maybe a second home
Possible tax angle
An RV with sleeping, cooking and toilet facilities may qualify as a second home, making interest potentially deductible if you itemize. Confirm with a tax pro.
shop the loan
Do not just take dealer finance
Dealer financing is convenient but not always cheapest. Compare a credit union or marketplace quote before signing.

How we calculate this
The formula and our assumptions
An RV loan is a standard amortizing loan on the amount financed.
financed = price + tax + fees − down − trade
The amount financed
Sales tax and fees add to the price; the down payment and trade-in subtract. The result carries the interest.
M = P·i ÷ (1 − (1 + i)^−n)
The payment
The level-payment formula on the amount financed, where i is the rate over twelve and n the number of months.
- Sales tax is charged on the full price; some states tax the price after a trade-in — adjust if so.
- The rate is fixed for the life of the loan.
- Carrying costs — insurance, storage, maintenance — are not included; budget them separately.

FAQ
Common questions
The amount financed is the price plus sales tax and fees, minus your down payment and any trade-in. That runs through the loan formula M = P·i ÷ (1 − (1 + i)^−n), where i is the rate over twelve and n the months. On an $85,000 RV with $10,000 down at 8.5% over 15 years, the amount financed is $80,600 and the payment is $793.70 a month.
RV and boat loans run far longer than car loans — commonly 10 to 15 years, and up to 20 years for large, expensive motorhomes. The long term keeps the monthly payment manageable on a big-ticket purchase, but it also means paying interest for a long time on something that depreciates, so the total interest can be substantial.
Lenders generally want good-to-excellent credit for the best rates — often 700 or above — because an RV or boat is a large, discretionary, depreciating purchase. You can borrow with a lower score, but expect a higher rate, a bigger down-payment requirement, or a shorter term. A strong down payment helps the approval and the rate.
Lenders often want 10% to 20% down on an RV or boat. On the $85,000 example, $10,000 is about 12%. A larger down payment shrinks the loan, lowers the payment, and reduces the risk of going "upside down" — owing more than the RV is worth as it depreciates.
Usually a little, yes. RVs and boats are seen as discretionary purchases and depreciate faster in some categories, so lenders price the risk higher than a car loan. Rates also depend heavily on whether the unit is new or used, its age, and the loan term — used and older units carry higher rates and shorter maximum terms.
Sometimes. If the RV has sleeping, cooking and toilet facilities, it can qualify as a second home, and the loan interest may be deductible like mortgage interest — subject to IRS rules and limits. It only helps if you itemize. This is tax-specific, so confirm with a tax professional before counting on it.
If you have the cash and the RV is a pure lifestyle purchase, paying cash avoids years of interest on a depreciating asset. Financing makes sense if the rate is low and you would rather keep cash invested or liquid. Either way, avoid stretching a long term just to afford a bigger rig than you need.
Plenty beyond the loan: insurance, registration, storage when not in use, maintenance and repairs, campground or marina fees, and fuel. These carrying costs can rival the loan payment, so budget for the whole picture, not just the monthly finance number, before you buy.
