THE EV TOOLKIT / PLANNING
Home vs. public charging and charger payback
Compare annual home and public charging costs, then estimate the simple payback of a home charger installation.
The full picture.
- Annual mixed charging cost
- $780.00
- Annual public-only charging cost
- $1,500.00
- Annual energy savings
- $720.00
- Simple installation payback
- 2.1 years
Estimates use constant prices, no investment discount rate and your stated assumptions. A negative savings result means the EV scenario costs more.
UNDERSTAND THE ESTIMATE
Assumptions matter.
Does the payback include installation and electrical upgrades?
Enter the complete installed cost, including equipment, labor and any electrical upgrades. The estimate uses energy savings only and excludes time savings, financing and changing tariffs.
Are these forecasts of actual costs?
No. The default inputs are examples. Replace them with your tariffs, quotes, driving estimates and expected costs. No fuel, installation or resale price is predicted by the tool.
Example sensitivity
Electricity costs across different public charging prices using the other example inputs.
| Public price / kWh | Annual mixed charging cost |
|---|---|
| $0.30 | $660.00 |
| $0.50 | $780.00 |
| $0.70 | $900.00 |
