What goes into the number
The five-year total combines six costs: depreciation, insurance, fuel, maintenance and repairs, tires, and loan interest. Depreciation is usually the largest — and the easiest to miss, because you only feel it when you sell or trade in.
Over five years the 2026 Toyota Prius is projected to lose about $10,364 of its value — roughly 36% of its $28,550 starting price — based on CarEdge retention data. That single figure often outweighs fuel and maintenance combined, which is why two cars with the same sticker can cost thousands apart to own.
The recurring costs — insurance, fuel, maintenance, and tires — are shown at national-average rates and 15,000 miles a year. Financing reflects a standard 5-year loan at the national-average new-car rate. Every number is built from real data — depreciation from CarEdge, fuel from current AAA gas prices — never a flat per-mile guess.
