Worked example
An EV costing £5,000 more, driven 10,000 miles a year, may recover that difference faster if most charging is cheap home charging rather than expensive public rapid charging.
Frequently asked questions
Does this prove an EV is cheaper overall?
No. It isolates purchase-price difference and energy cost. Depreciation, insurance, servicing, finance and resale value can materially change the result.
What charging price should I use?
Use a realistic blended price. Our Charging Mix Calculator can calculate one from home and public charging.
