Best Electrical Estimating & Takeoff Software for Contractors (2026)

If you run an electrical contracting business, your bid margin lives or dies on two numbers: how many devices you counted and how much conductor and conduit each circuit really needs. Generic construction estimating tools make you type all of that by hand. Electrical estimating software counts it the way an electrician thinks — and that is why more contractors are switching to a trade-specific tool for their electrical bids.

What electrical estimating software should do

Device takeoff from the plan. Count receptacles, switches, fixtures, dedicated/GFCI outlets, panels and load centers by clicking symbols on the PDF instead of tallying by hand.
Conduit and wire by circuit. Feet of raceway (EMT, PVC conduit, cable tray), conductor gauge (THHN/THW, #14, #12, #10, #8 AWG…) and feeder sizing by voltage drop.
Real unit-price assemblies. Cost per device, per circuit and per foot of raceway — material + labor + production rate — not a flat guessed number.
A material list you can order from. The estimate should output the conduit, wire, boxes, connectors and fittings takeoff ready for the supply house.

A tool built for exactly this is Amperio, electrical estimating and takeoff software. You can read an independent write-up on the Amperio listing at HubService.io.

The costliest mistake: pricing per device with no assembly

Most contractors bid "$X per installed device" and move on. That number hides the wire gauge, the run length to the panel and the raceway type. Two identical receptacles can cost double if one sits 25 feet from the panel in exposed conduit. Break the assembly down — material, feet of wire, feet of conduit, labor hours — and you stop losing money on long runs and stop overpricing short ones (and losing the job).

How it works in practice

Upload the electrical plan PDF.

Click the symbols: receptacles, switches, fixtures, power outlets, panels.

Draw the raceway per circuit and assign conductor gauge.

The software computes footage, materials and labor, then builds the assembly and the total.

Export the client proposal and the material list for the supply house.

Do this in a spreadsheet and every last-minute change (client moves a panel, copper price jumps) forces you to rebuild half the file. A dedicated electrical takeoff program recalculates automatically.

Already using general estimating software?

General construction software is fine for structure and finishes. But for the electrical scope — where device counts and conductor sizing decide your margin — a niche tool pays for itself. Plenty of contractors run both: the general estimator for the building and Amperio to nail the electrical package.

Bottom line: if electrical is your trade, estimate with a tool that speaks it — devices, circuits, gauges and assemblies — and stop leaving money on the table on every bid.
