Breakdown
Your driving
Leave this ticked if you charge at home and log those bills here. Home charging is then already counted in your bills, so the EV tab only subtracts public charging (no double counting).
Your system
Federal + state rebates combined.
Quarterly bills? Divide by 3.
Pro settings PRO
Unlock Pro to include loan repayments and rising electricity prices.
Forecast
Used for the forecast break-even. 3% is a common assumption; 0% means prices stay flat.
