What goes into the number
The five-year total combines six costs: depreciation, insurance, charging, 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 Plug-in Hybrid is projected to lose about $12,294 of its value — roughly 36% of its $33,775 starting price — based on CarEdge retention data. That single figure often outweighs charging and maintenance combined, which is why two cars with the same sticker can cost thousands apart to own.
The recurring costs — insurance, charging, 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, charging from current EIA residential electricity rates — never a flat per-mile guess.
