Assumptions and estimates
- Method: Grid charging energy divides battery energy by charging efficiency. Saving = combustion fuel cost − charging cost + entered non-energy savings.
- Use a charging price weighted across home and public charging. Excludes grants, resale differences, finance and battery replacement unless separately reflected in inputs.
Useful next steps
- Check the payback period against how long you will keep the vehicle.
- Use Compare options to test an alternative side by side.
- Copy, print or download a record of this calculation when you need one.
