Tips for Accurate Results
| Tip | Recommendation |
|---|---|
| Use real-world numbers | Official efficiency figures are often optimistic. Use actual consumption from your driving |
| Electricity rate | Use your home charging rate. Public fast charging is usually more expensive |
| Annual mileage | 12,000 miles (≈ 19,300 km) per year is a common average in the US |
| Consider other costs | This tool focuses on energy/fuel only. Add insurance, maintenance, and depreciation for full picture |
| Test different scenarios | Change distance or period to see how savings scale with more driving |
