RV Savings Calculator: Monthly Amount to Save Cash
Work out how much to set aside each month to buy an RV with cash — instead of financing it across years of 8% to 12% APR payments that often outlast the warranty.

How This Calculator Works
Enter the all-in target price (RV, taxes, registration, initial gear), the rate a savings account pays, and how long until you want to buy. The calculator solves for the monthly contribution that reaches the target, with the small amount of interest earned shown separately.
The Formula
Required Monthly Saving (Sinking Fund)
FV = goal amount, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Saving for a $60,000 RV over 4 years at a 3% savings rate needs about $1,178 a month. Deposits cover roughly $56,547 of the target; interest adds the remaining $3,453. Versus financing the same RV at 9% APR over 10 years, the savings route avoids about $20,000 of interest and ownership without payments.
Key Insight
RVs depreciate fast — typically 20% to 30% in the first three years — which makes financing one of the worst-value loans you can take. Buying with cash from a savings plan also lets you walk away from the purchase if priorities change, where financing locks in a monthly payment whether or not you actually use the RV.
Frequently Asked Questions
Why save instead of financing an RV?
RV loans typically run 7 to 15 years at 8% to 12% APR, against an asset that depreciates fast. Cash purchases avoid years of interest and remove the monthly payment that competes with using the RV.
What should the target price include?
RV price, sales tax, registration, initial accessories (towing setup, leveling gear, kitchen basics), and a 10% margin for the gap between sticker and actual out-the-door cost.
What return should I assume?
For a 1-to-3 year horizon, use a high-yield savings rate (currently 4% to 5%). Longer horizons can support slightly higher returns through a conservative bond portfolio.
What if RV prices rise while I save?
RV pricing tracks general inflation plus model year increases. Build a 10% to 15% margin into the target price, or revisit the figure annually and adjust the monthly contribution.
Should I buy new or used?
Used almost always wins on depreciation — most RVs lose the steepest value in the first 2 to 3 years. Letting the original owner absorb that hit can save 30%+ on the same model.

Methodology & Review
The required monthly contribution solves the future-value-of-an-annuity formula for the payment that reaches the RV target. Over a multi-year horizon, interest earned meaningfully reduces what you need to deposit each month.
