# EV charger load and cost estimator

Estimate charger input power and add your own written installation quote. This does not measure spare panel capacity, size a circuit or confirm a rebate. All money inputs use USD.

Use the tool on the [web page](https://electricianpros.fyi/tools/ev-charger-load-cost-estimator). It works without JavaScript.

## How to use it

1. Choose nominal supply voltage.
2. Enter configured charging current.
3. Enter equipment quote.
4. Enter installation labour and materials quote.
5. Enter permit, inspection and other quoted fees.
6. Enter quoted tax.
7. Enter confirmed incentive amount.
8. Read the result.

## How it works

US Department of Energy AFDC, Electric Vehicle Charging Stations, fetched and checked 2026-11-10: https://afdc.energy.gov/fuels/electricity_infrastructure.html . DOE describes 120 V Level 1, 240 V residential and 208 V commercial Level 2 charging. Its 240 V, 30 A example gives 7.2 kW. It also describes charging currents up to 80 A.

Power is nominal volts multiplied by configured amperes, divided by 1000 to express kilowatts. The result excludes losses and vehicle charging limits. It is not a branch-circuit or service load calculation.

US Department of Energy AFDC, Charging Electric Vehicles at Home, fetched and checked 2026-11-10: https://afdc.energy.gov/fuels/electricity-charging-home . DOE directs owners to an electrician to assess capacity and to local authorities for approvals.

Cost is the sum of the visitor supplied quote amounts. No typical equipment price, labour rate, tax or rebate is assumed. Money fields start at zero and have form bounds only. The incentive is subtracted with a floor of zero. For a Canadian quote, convert every amount consistently to USD before using this tool, or add the CAD quote outside it.

> For planning only. An electrician must confirm equipment, capacity, circuit design and local approvals. A cost total is arithmetic on your entries, not a contractor quote or rebate decision.

## Questions

### Does this tell me if my panel can support a charger?

No. It calculates the selected charger input power only. Ask an electrician for the service capacity assessment.

### Is the default current a recommendation?

No. It reproduces a DOE power example. Use the installed setting confirmed by your electrician.

### Where do the costs come from?

You enter them from your own written quote. A zero result means no quoted amounts have been entered.
