How to Use the EV Charger Cost-Share Calculator
When a condo or apartment building installs a new shared EV charger, participating units often split the installation cost among themselves. This calculator takes the total install cost, total units, and number of participating units to calculate each unit's share.
How the Split Works
The total install cost is typically divided by the number of units that sign up to participate. Fewer participants means a larger share per unit, so recruiting neighbors to join can lower everyone's cost. This calculator also shows what the cost would be if every unit in the building split it equally, for comparison.
Using Rebates
Government or utility EV charging infrastructure rebates can lower the total install cost, which lowers each unit's share as well. Check with your HOA or local utility for available incentives before finalizing the project.
Frequently Asked Questions
Usually the participating units that sign up split the cost equally, though government or utility rebates can lower each unit's out-of-pocket share.
Since total cost is divided by the number of participating units, fewer participants means a larger share per unit.
Charging units who never use the charger can cause complaints, so splitting cost among only those who sign up is the common approach.
