📊 RV Loan Calculator

RV loans stretch like mortgages: terms run 10 to 20 years, which shrinks the payment and balloons the interest. Finance $70,000 of an $85,000 RV at 7.5 percent for 15 years and the payment is $648.91 a month, but total interest reaches $46,803.56, two-thirds of the amount borrowed. This calculator shows both numbers before you sign.

Dealers sell the payment, not the loan. “Only $649 a month” sounds gentle; $46,789 of interest over 15 years on a depreciating asset is the rest of the sentence. Always price the total before falling for the monthly.

How to Use This Calculator

Enter the RV price, down payment, APR, and term in years. The calculator amortizes the loan monthly and reports the payment, total interest, and the true all-in cost of the RV.

The RV Loan Formula

The standard amortization formula: each payment covers that month’s interest with the rest reducing principal. Long RV terms keep r small relative to n, which is exactly what makes early payments almost all interest. In year one of the example loan, roughly $5,100 of the $7,786 paid is interest.

RV rates run higher than auto rates because the collateral is a luxury that depreciates fast and the terms are long. Excellent credit might see 6 to 8 percent; weaker credit pays well into double digits. Every point on a 15-year term costs thousands, so rate-shop before you shop RVs.

Worked Example

$85,000 price, $15,000 down, 7.5 percent APR, 15 years. Financed = $70,000. Monthly rate = 0.00625, 180 payments. Payment = $70,000 x 0.00625 x 1.00625^180 / (1.00625^180 - 1) = $648.91. Total paid = $116,803.56. Interest = $46,803.56, which is 55 percent of the RV’s price paid again as interest.

Shorter-term version: same loan at 10 years. Monthly rate 0.00625, 120 payments: payment = $70,000 x 0.00625 x 1.00625^120 / (1.00625^120 - 1) = $830.91. Total interest = $830.91 x 120 - $70,000 = $29,709.49, saving about $17,094 versus the 15-year term for $182 more per month. If the budget allows, the shorter term is the cheaper RV. Our loan amortization calculator shows the year-by-year split.

The Depreciation Trap

RVs depreciate 20 to 30 percent in the first few years while long loans pay principal slowly, so most buyers spend years underwater: owing more than the RV is worth. A bigger down payment is the only reliable shield. Never roll negative equity from a trade-in into an RV loan; it deepens a hole that takes a decade to escape. And budget the running costs: insurance, storage, maintenance, and fuel often rival the payment. Our auto loan calculator handles the shorter-term vehicle math for comparison.

Full-Timing: The Real Monthly Budget

The loan payment is only the headline. Full-time RVers typically add $150 to $400 for insurance, $300 to $800 for campground fees or lot rent, $100 to $200 for maintenance reserves, plus fuel that swings wildly with travel pace. A $649 payment easily becomes a $1,500 monthly lifestyle. Budget the lifestyle before the loan, because the loan is the cheapest part of the dream.

The financial escape hatches: buy used (the steepest depreciation is already gone), keep an exit fund of three months’ total costs, and know the resale market for your model before buying. RVs are luxury depreciating assets financed like houses; that combination demands either a short term, a big down payment, or a clear-eyed acceptance of the cost. None of those is wrong. Borrowing blindly for 20 years on a depreciating toy, then discovering the lifestyle costs, is.

Refinancing an RV Loan

RV refinancing works like auto refinancing: if rates fall or your credit improves, a new loan at a lower rate cuts the payment or the term. The catch is collateral value: lenders will not refinance an underwater RV, and long original terms plus fast depreciation keep many owners underwater for years. The refinancing window opens when the balance finally drops below market value.

Run the refinance math on total interest, not the monthly payment alone. Extending the term to cut the payment can raise lifetime interest even at a lower rate: the classic dealer refinance trap. Shorten or hold the term while cutting the rate and the savings are real. And watch fees: origination and title costs eat the first months of savings. If the break-even exceeds two years, think twice.

The 20-Year Trap in Numbers

Stretch the example loan to 20 years at 7.5 percent: the payment falls to about $565, but total interest climbs past $65,000, nearly the amount borrowed. Each extra five years of term buys roughly $80 of monthly relief and sells roughly $9,000 of interest. The trade is almost never worth it unless the budget genuinely cannot stretch, and even then a cheaper RV beats a longer loan.

Dealers push long terms because the payment sells the unit; the interest is the buyer’s problem discovered years later. Counter by negotiating the out-the-door price first, the rate second, and the term last, never letting the payment be the only number discussed. The buyer who prices total cost holds all the cards. Play that hand.
