ContractorAI is an AI estimating, invoicing and CRM app for contractors, available for iPhone and iPad. ContractorAI's electrical estimate calculator builds an electrical bid circuit by circuit. Add lighting, receptacle, appliance and HVAC circuits, pick the wire type and gauge (NM-B, UF-B, THHN or SER, 14 to 6 AWG), conduit, breakers and panel size, then set your labor rate and markup. You get an itemized electrical estimate you can send from your phone.

ELECTRICAL ESTIMATING PROBLEMS
Every circuit means wire, boxes, a breaker and labor. Missing one on a remodel comes straight out of your profit.
Copper wire and conduit prices change often. An estimate built on old numbers can lose money.
A 100 to 200 amp upgrade can bring in permits, utility coordination, new breakers and grounding work.
An itemized quote sent the same day is easier to trust and approve than a number written on a business card.
ELECTRICAL CALCULATOR FEATURES
Built for electricians. Every number can be edited before you send the estimate.
Add lighting, receptacle, appliance and HVAC circuits at 120 or 240 volts with 15 to 50 amp breakers.
NM-B, UF-B, THHN and SER in common gauges from 14 AWG to 6 AWG, with a run length for each circuit.
EMT, PVC and flexible conduit in 1/2, 3/4 and 1 inch sizes.
