EV vs petrol at 15,000 miles per year

Drive 15,000 miles a year? That is a common commuter mileage in the UK and where fuel or charging costs make the biggest difference. This calculator is pre-filled for 15,000 miles—adjust any figure to match your car and tariff.

Quick answer at 15k miles

On typical UK assumptions (45 MPG petrol at 145p/litre vs 30 kWh/100mi EV with mostly home charging), petrol fuel alone often costs around £2,000+ per year while EV charging might be £900–£1,400 depending on your tariff and public charging share. Add road tax and servicing for the full picture below.

Summary

The EV is estimated to cost £1,043 less per year to run (£5,216 over 5 years).

With a £7,000 higher EV purchase price, running-cost savings could offset the premium in roughly 6.7 years (ignoring resale value and finance).

Total cost of ownership over 5 years (purchase + running): petrol £38,686, EV £40,470. Petrol ahead by £1,784.

Frequently asked questions

  • Is an EV worth it at 15,000 miles per year?

    Higher mileage usually strengthens the case for EVs on running costs alone, because cheaper per-mile charging (especially at home) adds up faster. You still need to weigh purchase price, insurance and how often you use expensive public chargers.

  • How much does petrol cost at 15,000 miles per year?

    At 45 MPG and 145p per litre, 15,000 miles uses roughly 1,515 litres—about £2,200 per year on fuel alone, before tax and servicing. Enter your actual MPG and local fuel price in the calculator.

  • How much does EV charging cost at 15,000 miles?

    At 30 kWh per 100 miles, 15,000 miles uses 4,500 kWh per year. At a blended 30p/kWh that is roughly £1,350 annually—often less than petrol, though public-heavy charging patterns reduce the gap.
