← EV Charger Install Bid Calculator
This calculator vs. Workiz
Two different shapes: Workiz is an account-based field service management platform for running an electrical company's whole operation. This page is a free, private worksheet for one question — what should this one EV charger install cost, given its amps, its run, and its panel situation, before you quote it.
What each tool is for
Workiz is a field service management platform used by electrical, HVAC, and other trades to run scheduling, dispatch, invoicing, online payments, and reporting across a whole business, with a mobile app for crews in the field. It is an account-based platform: you sign up and use it as an ongoing service across a whole company, not a one-off calculator. Workiz's own pricing page is not reachable from this session to confirm today's exact plan names or dollar figures, so no price for it is invented here: only its well-documented identity and category — field service management software serving the electrical trade among others, sold as a subscription account — are stated, and no dollar amount for Workiz appears on this page.
This calculator does none of what Workiz does. It does not schedule electricians, dispatch crews, or invoice a customer, and it stores no customer or job record on a server. It takes one job's charger continuous amps and install type (hardwired or a NEMA 14-50 receptacle), the mounting location (indoor garage, outdoor wall, detached garage, or pedestal), the one-way run and any trench footage, the panel work the job needs (a spare slot through a service upgrade), and the existing service and estimated existing load, plus journeyman wage, payroll burden, permit and inspection fee, charger hardware where it is not owner-supplied, overhead, and target margin. It turns that into the price, the labor hours behind it, the effective hourly rate, the price per circuit amp and per run foot, and the walk-away price below which the job loses money — plus, if you already have a price on the table, a check of whether it clears that floor. It runs free in any browser, keeps no account, and uploads nothing you type.
| Question | Where to answer it |
|---|---|
| I run an electrical company and need scheduling, dispatch, invoicing, payments, and job costing across every crew and every job. | Workiz, or a comparable field service platform — running a whole company is not something this calculator does. |
| What should I charge for this EV charger install, given its amps, its run, and its panel situation? | This calculator — free, instant, private, no account. |
| How much does a detached-garage install with a long trench and a service upgrade actually add over a spare slot in the garage panel? | This calculator's location, trench, run, and panel-work factors, not a flat per-charger price. |
| Is the run long enough that voltage drop pushes me to a larger conductor, and what does that do to the bid? | This calculator's voltage-drop and wire recommendation, which feed the same material cost the price is built from. |
| Is the price I'm about to quote still above my walk-away cost for this job? | This calculator's compare-to-proposed-price check. |
| I need one shared account so my whole crew is scheduling, dispatching, and invoicing the same way. | Workiz, or a comparable field service platform. |
| How does the math behind an EV charger bid actually work? | This calculator's own pricing walkthrough. |
| Do I need to create an account or sign up to use the tool? | This calculator: no. Workiz is used through a subscription account. |
Most electrical shops get different value from each: Workiz (or a comparable field service platform) for scheduling, dispatch, invoicing, and job costing across a whole company as an ongoing subscription, and a private calculator like this one for an instant, no-login answer to what one EV charger install should cost from its amps, its run, and its panel situation before a business system is involved. This page's own figures are a pricing model, not a permit load calculation, an invoice, or a signed proposal.
This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
Common questions
Should I use this calculator or Workiz?
They do different jobs, and an electrical contractor of any size will likely end up touching both eventually. Workiz is a field service management platform used by electrical, HVAC, and other trades to run scheduling, dispatch, invoicing, payments, and reporting across a business, sold as an ongoing subscription account. This calculator does one narrower thing: starting from the continuous amps of the charger and the install type, with the one-way run, trench footage, mounting location, panel work, and the existing service and load as their own line items, plus journeyman wage, payroll burden, permit, overhead, and target margin, it turns that into the price, the labor hours behind it, the effective hourly rate, and the walk-away price below which the job loses money, before any of it touches a business-management system. It runs free in any browser, keeps no account, and uploads nothing you type. An electrical contractor who already schedules electricians, dispatches crews, and invoices across every job is better served by Workiz or a comparable field service platform; a shop that wants an instant, private answer to what one EV charger install should cost from its amps, its run, and its panel situation is in the right place here.
Does this calculator size the wire and breaker for me?
It shows a suggested breaker size, a wire recommendation, and the voltage drop over the run you entered, because those three change the cost of the job more than anything else on the form and a bid written without them is a guess. They are an estimating aid and nothing more. This page is not a permit load calculation, it does not determine NEC or local-code compliance, and it does not tell you a panel is safe. Verify every figure against your own takeoff, the nameplate, the adopted code, and a licensed electrician before you submit a bid or pull a permit.
