The Real Cost Of Doing Business For An Australian Electrician

Most sparkies charge what feels right. Then they wonder why the bank account doesn’t grow even when the work doesn’t stop.

The fix starts with one number: your real cost of doing business. Until you know what an hour of your business costs to run, every quote is a guess.

What “cost-to-operate” actually means

It’s every overhead that has to be paid before you make a dollar of profit. It’s not just wages.

Run through this list and write down a real annual figure for each:

• Owner take-home: the wage you want to draw. Be honest about what you need.
• Super on owner pay: 11.5% as of 2026.
• Vehicle costs: lease/loan or depreciation, fuel, rego, insurance, servicing, tyres, tolls.
• Insurances: public liability, tools, income protection, business pack.
• Software & subscriptions: accounting, quoting, scheduling, comms, design.
• Accounting & legal: yearly accountant, BAS lodgement, contracts review.
• Phone & internet: mobile, office, data.
• Tools & consumables: replacement, calibration, test & tag.
• Marketing: website, ads, signage, branded gear.
• Training & licences: your own licence renewal, CPD, AS/NZS updates.
• Other: admin time, bookkeeping, leave loading, sick pay, bad debt.

Add it up. For a solo Australian electrician, the total is usually $80,000 to $130,000 a year, before you’ve made a dollar in profit, and that’s pretty conservative.

Divide by real billable hours

The trap is dividing by 38 hours × 52 weeks. You don’t work 1,976 billable hours a year. Nobody does.

Realistic billable hours for a working sparky:

• 4 weeks annual leave: −152 hours
• 2 weeks public holidays/sick days: −76 hours
• Quoting time, admin, travel, materials runs: 20-30% of remaining hours

You’re typically left with 1,300 to 1,500 billable hours a year.

So if your annual cost-to-operate is $110,000 and you bill 1,400 hours, your cost per billable hour is roughly $78.50. Below that, you lose money. At cost, you break even.

Add margin to get charge-out

Cost-to-operate is what you need to survive. Margin is what makes the business grow. It pays for tools, training, slow weeks, the next van.

If you wanted a 25% margin on that $78.50 cost:

Charge-out = $78.50 ÷ (1 − 0.25) = $104.67/hr

Round to $105. That’s your real charge-out rate. If you’re charging less, you’re losing money on every hour billed.

The Hourly Rate Calculator does the maths for you in 60 seconds.

Why this matters more than ever

Vehicle prices are up. Insurance is up. Software is up. Wages are up. Has your charge-out rate moved?

Most haven’t. That’s why margins are dropping across the trade. Not because work is harder to win, but because nobody’s reviewing the base rate.

The Estimating Masterclass builds in a quarterly review ritual so this never drifts again.

The fix in one weekend

The Electrical Estimating Course walks you through cost-to-operate, labour rate, margin and quoting in detail, with Australian examples and real templates. Run the system once, lock it in, and never guess at a quote again.

And once the method is locked in, TradieTally runs it for you on every quote, including live charge-out rate updates and Business Brain showing actual recovery.

You can’t price a job right until you know what an hour of your business costs to deliver. That’s where every profitable estimating system starts.
