Electrical estimating is how a contractor works out what an electrical job will cost before bidding it, and it comes in two parts. The first is building the bill of materials (BOM) from the drawings themselves, which means counting the devices, panels, fixtures and the instruments in the instrument index, and measuring every conduit, cable and tray run. The second is the labor takeoff, which puts install hours against every line on that BOM. Every price on an electrical bid is built on those two parts.
Most of that work is still manual. Cable schedules often list footage for tray and conduit together without saying how much runs in each, so an estimator goes back to the plans and scales it off by hand. Some plans arrive as locked PDFs that won’t hold a scale, and estimators measure them with a physical ruler. Once the quantities are done, the estimator builds the labor takeoff line by line against their own productivity rates, and on an industrial package the two parts together take 30 to 40 hours before a single price goes on the bid.
Electrical teams now bid more jobs with fewer estimators, so an estimate that takes most of a week leaves less time to check quantities or chase the next bid. AI electrical estimating software was built for that week. The better electrical estimating software now builds the BOM from the drawings and runs the labor takeoff on top of it, and the estimator checks the work instead of producing all of it by hand.
This list covers the 10 best electrical estimating software options electrical contractors are using in 2026, what the AI in each one actually does, and where the work is still left to the estimator, so you can pick the right estimating software for electrical contractors in your position.
What Is Electrical Estimating Software?
Electrical estimating software turns a bid package into a priced electrical estimate. AI electrical estimating software goes further and reads the package itself, producing the estimate in two parts: a BOM built from the drawings, with device counts, conduit and cable lengths, and panel and fixture schedules, then the labor takeoff that puts hours against each line. An estimator then reviews and adjusts those numbers instead of building them from zero.
The real difference from older electrical estimating software is who does the counting. With a traditional tool, you click every symbol yourself. With AI for electrical estimating, the software finds the symbols, measures the runs and hands you a first pass to check. Most tools read PDF plans, and the stronger ones also read panel schedules, one-line diagrams and cable schedules, so the quantities on the takeoff agree with the rest of the package.
How AI Electrical Estimating Software Differs From Traditional Electrical Estimating Programs
Traditional estimating software for electrical work was built around a database. You did the takeoff, the program priced it against its item list and labor units, and the bid was only as good as your counting. Plenty of electrical estimator software and electrical estimate software sold before 2023 still works this way, and it does the pricing well.
AI takeoff software moves the effort to the front of the job. AI electrical estimating software handles the counting, and a few tools go further by working out quantities the plans never state outright, such as the home run from each device back to its panel, or how a cable schedule's total footage splits between tray and conduit. That second step is where most hand takeoffs come in short. It's also where the tools on this list differ the most.
10 Best Electrical Estimating Software in 2026
1. The Takeoff AI
The Takeoff AI is the best electrical estimating software in 2026. It estimates from single-line diagrams (SLDs), power and lighting plans, conduit and tray layouts, and returns the full estimate in under 3 hours.
It handles both parts of electrical and instrumentation (E&I) estimating. It builds the material takeoff (MTO) straight from the drawings, counting devices, panels, fixtures and instruments and measuring every conduit, cable and tray run, then runs the labor takeoff on every line using your own productivity rates, so material and labor come out together as a priced BOM.
The Takeoff AI is built on AI models trained on more than 1.2 million electrical and instrumentation drawings. It delivers 95% accuracy, and every number is highlighted on the drawing it came from so your estimator can check it before the bid goes out.
Estimators using it finish projects in 2 to 3 hours that used to take 30 to 40 hours, saving 90 to 95% of their estimating time, and more than 400 of them say it’s the best electrical estimating software they’ve used.
Beyond electrical, The Takeoff AI estimates piping, P&ID (piping and instrumentation diagrams), isometrics, mechanical, plumbing, HVAC including ductwork, structural steel and misc iron.
Above is The Takeoff AI running an electrical estimate, from the drawings to a priced BOM, in under 3 hours.
2. Trimble Accubid Anywhere
Trimble Accubid Anywhere is cloud based electrical estimating software. Its AI detects and counts symbols, names pages, sets scale and routes conduit to calculate run lengths, while several estimators work one job against a shared database. Setup is heavy, so it suits commercial electrical estimating software buyers with a big assembly library. Reviewers say long-time users can’t carry their old databases over and have to rebuild them.
3. Countfire
Countfire handles the slowest part of electrical estimating: select a symbol once and it counts every instance across every sheet. It compares specifications between revisions and runs in the browser. The automation stops at devices and fixtures, so conduit, tray and cable runs are still measured by hand, and reviewers say auto-count struggles on messy or heavily marked-up drawings.
4. Drawer AI
Drawer AI is electrical-only. Upload a plan set and it detects devices, routes branch circuits and sizes wire automatically, which covers more of the job than symbol counting does. It's aimed at electrical subcontractors who want a simple tool, and Drawer pitches it as an electrical estimate app you can pull numbers from while on a call or on the way to a jobwalk.
5. Togal.AI
Togal.AI detects and measures rooms, areas and symbols on uploaded plans and works across trades, electrical included. For a contractor who bids several trades, that breadth is the appeal. For a pure electrical contractor the trade logic is thinner, so home runs and labor units are still built by hand, and reviewers say the AI misses some items, such as electrical penetrations.
6. Beam AI
Beam AI (also sold as iBeam) works closer to an outsourced electrical estimating service than software you drive yourself. You send the plans, its AI and review team produce the takeoff, and the quantities come back for you to price. You give up control over the counts, and reviewers mention turnaround of about three days and takeoff layouts that don’t match their bid forms.
7. STACK
STACK is a cloud takeoff and estimating platform for every trade, with AI takeoffs, symbol search and an AI chat assistant called STACK IQ. As electrical construction estimating software it works once configured, but expect to build electrical assemblies and labor units yourself before it matches a purpose-built tool. Reviewers say it lags or freezes on large, complex drawing sets.
8. Kreo
Kreo is a multi-trade takeoff tool with Auto Count, Auto Measure and AI scale detection, plus an AI assistant called Caddie. It suits buyers of AI construction estimating software who want counts and measurements fast across several trades, but the AI tools sit on the Pro plan only, and labor units and pricing happen somewhere else. Reviewers say auto-measure is unreliable on poor scans and dense drawings.
9. Takeoff Boost
Takeoff Boost adds AI to On-Screen Takeoff. Upload a plan and the AI returns area, linear and count quantities as a head start, and those quantities move into the estimate as material and labor costs, which makes it electrical estimating takeoff software and electrical bid software in one workflow. An estimator still finishes the electrical logic, and reviewers say its reports are limited, so many rebuild pricing in Excel.
10. McCormick Systems
McCormick carries a database of more than 55,000 items and 25,000 assemblies, an Auto Home Run feature and auto-count for repeated symbols, which makes it dependable electrical cost estimating software. Its AI is still arriving, since McCormick lists AI-assisted symbol detection as a 2026 project, so the counting is mostly yours today. Reviewers often call the interface dated.

The Electrical Estimator Shortage
There are fewer electrical estimators every year, and the takeoff work they do is still mostly manual. The Shortage of Estimators, built on Bureau of Labor Statistics (BLS) figures, counts about 221,400 US cost estimators, projects a 4% decline by 2034 and finds roughly three in four estimator seats will need refilling over the decade. Fewer people carrying more bids can’t keep counting devices and scaling cable runs by hand. The Takeoff AI also suits electrical contractors expanding into data center work, the subject of The Data Center Boom Has A Problem.
FAQs About Electrical Estimating Software
What Software Do Electrical Estimators Use?
Most electrical estimators use an estimating program for pricing and labor units, often paired with a takeoff tool for counting. The Takeoff AI covers both, building the takeoff from the drawings and pricing it into a priced BOM in under 3 hours.
What Is the Best Electrical Estimating Software?
The Takeoff AI is the best electrical estimating software for contractors bidding electrical projects who want accurate estimates. It handles industrial and E&I packages end to end, saves estimators 90 to 95% of their estimating time and returns a priced BOM in under 3 hours.
How Do You Do an Electrical Estimate With AI?
Upload the plan set and schedules, let the electrical estimating software build the BOM and the labor takeoff, then check each count against the sheet. On The Takeoff AI, the estimate comes back priced against your own labor rates.
How Do You Estimate Electrical Jobs Faster?
Hand the counting and measuring to AI electrical estimating software and reuse the assemblies and labor units from past bids. Estimators using The Takeoff AI finish projects in 2 to 3 hours that used to take 30 to 40 hours.
Can AI Estimate Industrial Electrical and Instrumentation Work?
Yes, though few tools do it, because most AI takeoff tools were built for commercial buildings. The Takeoff AI reads industrial E&I packages, including cable schedules and the instrument index, and counts instruments alongside the electrical scope.
How Do You Use Electrical Estimating Software?
Set up your labor units and assemblies once, build the BOM from each new set, run the labor takeoff, review the counts, then price and export the bid. With AI electrical estimating software, the estimate shrinks from days to hours.
Choosing the Best Electrical Estimating Software
There are fewer electrical estimators every year, and counting devices and tracing conduit by hand is still the part of the job that takes most of their time. The Takeoff AI is the best electrical estimating software for contractors who need the takeoff done and priced in hours. It pulls the electrical and instrumentation scope out of a thousand-page package, counts and measures every item, prices labor against your own rates and gives you a priced BOM in under 3 hours.
