Charging cost and time calculator
Plain assumptions you can change
Charging speed depends on the car, the charger and the battery's state. This is a planning estimate.
Time
AC: energy added divided by the lower of the charger's power and what your car accepts (about 3.3 to 11 kW for cars, assumed from battery size). DC: about 85% of peak power up to 80%, then a slow taper.
Cost
You pay for the units drawn, which is more than the battery stores: about 12% extra at home and 5% at public chargers. Public charging adds 18% GST; home electricity doesn't.
Range added
Energy added divided by real-world consumption (claimed range × 70 to 82%, by test cycle, or the brand's own real-world figure where published). Specs: .
Which chargers actually work?
Charger status, real prices and queue times from drivers in your city. Free, and always will be.

Questions people ask
How is charging time estimated?
AC time is the energy added divided by the power your car accepts, which is the lower of the charger and the car's on-board charger. DC fast charging assumes about 85% of peak power up to 80%, then a taper. Real sessions vary with battery temperature, state of charge and charger health.
Is GST charged on EV charging?
Public charging carries 18% GST, which is added by default. Home electricity is not charged GST. You can change the figure.
Why are the units billed more than the battery gained?
Some energy is lost as heat between the plug and the battery. You pay for the units drawn, not the units stored.
What price should I enter?
Use your home tariff for home charging, or the price shown in the charging app for public chargers. Defaults are typical, not live prices.
Can I charge to 100%?
Yes. The last 20% is slow on DC fast chargers, so time rises steeply above 80%.
