Frequently asked questions
Is an EV charging subscription worth it?
It is worth it when the monthly fee is smaller than your yearly kWh multiplied by the per-kWh saving. The break-even table shows the kWh you need each month.
Why include charging losses?
Energy is lost as heat between the charger and the battery, typically 5 to 15%. You pay for that energy, so ignoring it understates real cost.
Is the EV Charging Membership Calculator free?
Yes. EV Charging Membership Calculator is completely free with no sign-up, limits or watermarks.
Is my data private when I use the EV Charging Membership Calculator?
Yes. It runs in your browser, so your input is not uploaded to our servers.
