Worked example
Someone charging 70% at 8p/kWh, 20% at 35p and 10% at 75p has a very different real-world charging cost from someone relying mostly on rapid chargers.
Frequently asked questions
Do the percentages have to total exactly 100%?
No. The calculator normalises them automatically, although entering a true 100% split is clearer.
Can I use this figure elsewhere?
Yes. Use the blended p/kWh result in the Petrol vs EV or EV Break-Even calculators.
