How to Use the EV Charging Cost Calculator
The cost of charging your electric vehicle can vary significantly depending on whether you use DC fast charging or Level 2 slow/home charging. Fast charging is convenient but typically costs 2–3 times more per kWh. This calculator helps you compare both options based on your actual usage patterns.
Enter your battery capacity, the per-kWh price for each charging type, how much you charge each session, and how many times per month you use each. You'll instantly see the cost per session, monthly total, and annual spending for your current charging mix.
Frequently Asked Questions
