About ChargeCostCalculator.com
Reviewed by Edward, publisher and site editor ·
I’m Edward, an EV owner and IT systems engineer in Malta, and I run ChargeCostCalculator.com independently.
I built the site because charging-cost figures often look more precise than they really are. Battery capacity, electricity price and charging losses can all change the answer, so I wanted those assumptions to stay visible and easy to replace with your own numbers.
Why I built it
When I started looking more closely at EV charging costs, I kept finding headline figures without enough detail behind them. It was not always clear whether a calculation used usable battery capacity, whether charging losses were included or whether the electricity price was a real tariff or a broad average.
The calculators keep those inputs separate, which makes it possible to check a result and rerun it with the figures from your own electricity bill and your own car.
How I maintain the site
I maintain the calculators, review the sources and check updates before they are published. I also review reader-reported corrections when a tariff, specification or link changes.
Software tools help with research organisation, arithmetic checks and editing, but I make the final call on the sources, assumptions and corrections that appear on the site.
Advertising and independence
Advertising helps cover the cost of running the site. It does not change the formulas, country data, vehicle coverage or source selection.
Practical limitations
The calculators produce estimates, not utility quotes or laboratory measurements. Temperature, charger hardware, battery conditioning, tariffs, parking and public-network fees can all change the real result.
For an important decision, check the relevant electricity provider, charging operator or vehicle manufacturer as well as the calculation shown here.
