Home vs Public EV Charging Cost Comparison
Compare annual charging cost by your mix of home charging and public charging.
Formula
Annual cost (your mix) = All at home × Share charged at home (%) + All public charging × (1 − Share charged at home (%))
Assumptions
Compare annual charging cost by your mix of home charging and public charging.
How to read it
The share charged at home is the variable that changes everything: at 80% home charging, fast chargers stay a footnote in the budget; without private charging, compare seriously against petrol before buying.
