A calculator on vanlifemag.de compares the annual cost of owning a camper van with renting one for the same number of travel days. It includes depreciation, lost interest and fixed costs. With default settings (purchase price €65,000, eight-year ownership, 40% residual value, €2,400 annual running costs, average rental €110 per day), the break-even point is 71 travel days per year. Fuel, tolls and campsite fees are excluded because they are the same for both options.
