Question 1

How accurate is this cost calculator?

Accepted Answer

This tool provides a precise calculation based on the numbers you enter. Its accuracy depends entirely on the quality of your inputs. For the most accurate results, use the specific cost per kWh from your electricity bill and the official efficiency (Wh/km or mi/kWh) for your vehicle model. The petrol comparison is also based directly on the price and MPG you provide.

Question 2

Does this calculator include maintenance and insurance?

Accepted Answer

Yes, you can optionally include these factors. The tool allows you to toggle on average maintenance savings (£300/year for UK, $450/year for US) and select an estimated insurance differential (+10%, neutral, or -5%). These are based on industry averages but provide a more complete picture of total running costs.

Question 3

What’s included in the monthly EV running costs?

Accepted Answer

The 'monthly running cost' includes the cost of electricity for the distance you drive. If you enable the options, it will also factor in average annual maintenance savings (spread over 12 months) and a percentage-based adjustment for estimated insurance cost differences, giving you a more holistic view of what you might spend or save.

Question 4

What is a Time-of-Use (TOU) tariff?

Accepted Answer

A Time-of-Use (TOU) tariff is a pricing plan where the cost of electricity changes based on the time of day. It's typically cheaper during 'off-peak' hours (like overnight) and more expensive during 'peak' hours of high demand (like late afternoons). Our calculator supports TOU to help you find the cheapest time to charge.
