Electrical Estimating For Beginners: How To Price Your First Jobs

You can wire a board in your sleep. Then someone asks “how much?” and the confidence drains out of you. Welcome to electrical estimating, the part of the trade nobody teaches on the tools and the part that decides whether your business pays you properly.

The good news: estimating is a system, not a talent. Once you understand the five moving parts, you can price any job without the knot in your stomach. Here’s the beginner’s version. For the full picture, the electrical estimating guide ties it all together.

Step 1: Work out what your business actually costs to run

Before you price a single job, you need one number: what an hour of your business costs to keep the doors open. Not what you pay yourself, what it costs, vehicle, fuel, insurance, tools, software, phone, super, leave, admin time.

Add those up across a year, divide by the hours you can realistically bill, and you’ve got your true cost-to-operate. This is the foundation. Every quote sits on top of it. There’s a full walkthrough in the real cost of doing business.

Step 2: Set a charge-out rate, not a wage

Beginners almost always set their rate by copying the sparky down the road or doubling what they used to earn as an employee. Both are guesses.

Your charge-out rate is your cost-to-operate plus the profit you want to make. If it costs you $70 an hour to run the business and you want a 30% margin, you’re charging well north of that, not adding “a bit on top”. Get this number right once and it carries every job you ever quote.

Step 3: Take off the materials

Now the job in front of you. Go through the plans or the site and count everything, points, switches, lights, cable runs, the board, the bits of make-good. Quote them by system (lighting, power, data) so nothing hides inside a lump sum.

The trap for beginners is the small stuff: glands, conduit, clips, the second trip to the wholesaler. Under-count materials and you eat the difference. Count properly and you protect the margin you set in step 2.

Step 4: Estimate the labour honestly

This is where most first quotes go wrong. The job that “should be a day” becomes two, and the price only had a day in it.

Don’t guess the whole job. Break it into tasks, rough-in, fit-off, terminations, testing, travel and setup, and time each one. Then add the bits that feel like they don’t count but absolutely do: loading the van, site setup, pack-down, cleanup. They’re all paid time. The labour hours method shows you how.

Step 5: Build the quote and add margin on purpose

Materials plus labour gives you your cost. Now apply your margin, and apply it the right way. A 30% markup is not a 30% margin (it’s about 23%), and that gap costs beginners thousands over a year. Set a target margin and work the price back with Sell = Cost ÷ (1 − margin).

Add a line for variations terms, a contingency for the unknowns, and GST, and you’ve got a real quote, one you can defend, not a number you pulled out of the air.

What to do next

That’s electrical estimating, start to finish. None of it is hard. It’s just never taught, so most sparkies learn it by losing money for a few years first. You don’t have to.

Estimating isn’t a gift some sparkies are born with. It’s five steps. Learn them once and quoting stops being the scary part of the job.
