For electrical contractors
Electrical contractor bidding software.
Service upgrades, panel replacements, EV-charger installs, residential rewires. Bid the job in 5 minutes, send a branded proposal the customer can sign in their browser, mark won and move on.
Three problems Electrical contractors keep hitting.
Problem 1
Permit cost + panel + breakers + labor + dwelling-load calc — every quote has 8 line items and most quote tools force you to type them every time.
ProJobCalc: Estimate templates (Pro tier) save your standard service-upgrade / panel-replacement / sub-panel line-item bundles. New quote inherits the bundle; you adjust the dwelling-specific numbers.
Problem 2
Homeowner wants 'just a quick price' over the phone — you need it in 90 seconds with confidence.
ProJobCalc: Voice estimator (Sage) — narrate the scope on the call, get structured line items in real time. Or use the free electrical calculator for the back-of-envelope number.
Problem 3
Apprentice + journeyman labor mix means your blended rate per hour is a moving target, and most calculators assume one rate.
ProJobCalc: Crew-day cost calculator handles the labor mix explicitly. Plug in 1 journeyman + 1 apprentice at their respective rates, get the burdened crew-day number you bid against.
Free Electrical calculators.
No signup. No tier gate. The calculators below open straight to the math — save the result if you want, or just take the number and move on.
Electrical Service Call Calculator
Price electrical service calls, diagnostic fees, and labor-hour jobs.
Labor Burden Calculator
Convert a wage rate into a true burdened cost including taxes, insurance, workers comp, and PTO.
Crew-Day Cost Calculator
Calculate the daily cost of a crew including burdened labor, vehicle, fuel, and jobsite overhead.
Markup vs Margin Converter
Convert between markup % and margin %. Most contractors confuse them — this tool prevents the $10k-a-year math error.
Electrical Service Upgrade Calculator
100A → 200A (or 320A, 400A) service-panel upgrade: panel, breakers, meter, SE cable, grounding, mast, permit, and labor for residential service upgrades.
Benchmarks (US averages, 2025).
100A → 200A service upgrade
$2,200 – $4,500
EV charger install (Level 2)
$800 – $2,500
Whole-home generator install
$8,000 – $22,000
Typical margin
30–45%
These are reference ranges. Your actual pricing depends on local labor + material costs + your overhead. Use the calculator above for a defensible per-job number.
Electrical questions.
Do you handle commercial electrical bidding?
ProJobCalc is residential-first. Light commercial (small office, restaurant) fits — the calculators handle it. Heavy commercial / industrial with one-line diagrams and specs is genuinely out of scope; you'd want McCormick or ConEst there.
Can the AI generator handle code references in the proposal?
Yes — you can mention NEC sections in the scope and the proposal will format them clearly. The model doesn't fact-check NEC clauses, so verify code citations yourself; treat it as a writing accelerator, not a code authority.
What about permit-fee variability by jurisdiction?
We don't auto-fetch local permit fees. Add the permit cost as a line item — the AI generator picks it up. On the roadmap to pull from public permit-fee schedules for the top 50 US metros.
