Cost is the energy added (kWh) × your electricity rate, and the tool also estimates range from the energy and an efficiency figure (kWh per km). It shows what a charge costs and roughly how far it goes.
Real consumption depends on speed, terrain, climate control, and load, and charging losses mean the grid draws a little more than lands in the battery. Use your observed kWh/km for a realistic range.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
