ABN to Wages Calculator: What Your Contractor Income Is Actually Worth

You’re pulling $90 an hour on your ABN and feeling pretty good about it. Then your mate who’s on the tools as a full-time employee mentions he’s on $65k a year — and suddenly you start second-guessing yourself. Who’s actually doing better?

This is exactly why every tradie working as an ABN contractor needs an ABN to wages calculator. Not a rough guess. Not a “she’ll be right” feel — actual numbers. Because the gap between your invoice rate and your real take-home is bigger than most people realise, and it can go either way depending on how you’re set up.

Why ABN Income and Wages Aren’t the Same Thing

When you’re on the payroll, your employer covers a stack of costs on top of your salary. Super, workers comp, payroll tax, annual leave, sick leave, public holidays — none of that comes out of your gross wage. It’s all in addition to it.

When you’re on your ABN, all of that is your problem. You’re the business. You pay your own super (or you don’t, and you’re burning your retirement). You fund your own leave. If you don’t work, you don’t get paid. And when tax time rolls around, you’re writing a cheque to the ATO instead of having it skimmed off quietly each fortnight.

That’s not a complaint — it’s just reality. ABN work can absolutely pay better. But only if you’re charging enough to account for what you’re no longer getting. Most tradies aren’t. They set their rate based on what sounds good, or what the bloke before them charged, and they never actually run the numbers.

What Goes Into an ABN to Wages Conversion

To convert your ABN contractor income to a wages equivalent, you need to account for several layers:

• Superannuation: Currently 11.5% on top of your wages equivalent. If you’re not putting this away yourself, you’re effectively earning 11.5% less than an employee on the same gross.
• Leave entitlements: Four weeks annual leave plus public holidays adds up to roughly 10–11% of annual salary for most employees. On your ABN, those weeks are unpaid unless you’ve priced them in.
• Sick leave: 10 days per year for most employees. You get zero. Factor in even half of that as risk buffer.
• Workers compensation insurance: Varies by trade and state, but typically 1–5% of annual income. Non-negotiable.
• Tax obligations: GST registration once you hit $75k, PAYG instalments, potential accountant fees, and BAS lodgement costs all add up.
• Income gaps: No work between jobs, travel time, quoting, admin — hours you don’t bill but still spend on the business.

Run all of that together, and a tradie billing $90/hr on ABN with 45 billable hours a week for 48 weeks might look like they’re crushing it — until you back out the real costs and see their wage equivalent is closer to $75–80k. Which might still be great. Or might be exactly what they’d earn on the tools full-time with leave and super included. The point is: know your number.

The Quick Formula (and Why It’s Not Enough)

A rough ABN to wages calculation goes like this:

1. Take your expected annual ABN income (total invoiced, before tax)
2. Subtract your business expenses (insurance, tools, vehicle, phone, etc.)
3. Subtract self-funded super contributions (at least 11.5%)
4. Add back the value of leave entitlements you’re forgoing (roughly 10%)
5. What’s left is roughly your wages equivalent before income tax

But here’s the issue: most tradies don’t track their business expenses properly, don’t separate personal and business spending, and have no idea how many hours they’re actually billing versus working. The formula only works when the inputs are accurate.

That’s where a proper subby to salary calculator earns its keep. You plug in your real numbers — hourly rate, billable hours, expenses — and it shows you what you’re actually taking home versus what an employee would be getting. It cuts through the noise and gives you a straight comparison.

Contractor to PAYG: When It Actually Makes Sense to Switch

Sometimes the numbers flip. There are scenarios where moving from ABN contracting to PAYG employment actually puts more money in your pocket:

• You’re not getting consistent work between contracts and your income gaps are killing your annual earnings
• Your employer is offering a package with vehicle, phone, tools, and super on top of salary
• Your ABN rate isn’t high enough to cover the true cost of self-employment (this is more common than people admit)
• You’re in a state or trade where workers comp is expensive and you’re exposed

On the flip side, ABN contracting wins when you’re disciplined about your finances, you’ve got consistent work, your rate genuinely reflects the cost of self-employment, and you can claim legitimate business deductions that reduce your taxable income.

Neither structure is automatically better. The math decides. Do the calculation, not the vibe check.

ABN Pay Calculator vs Full Business Rate Calculator

An ABN pay calculator is useful for comparing your contractor income to an employee wage. But if you’re trying to work out what you should be charging as a tradie running your own business — not just as a subcontractor on someone else’s jobs — you need something more comprehensive.

A full charge-out rate calculator factors in your overhead: business insurance, vehicle costs, tool depreciation, marketing spend, software subscriptions, and a margin for profit. The difference matters. A subcontractor can get away with a simpler income-to-wages comparison. A trade business owner needs to understand their full cost base before they set a price.

The Advanced Tradie Calculator covers both — it’ll give you a proper charge-out rate based on your actual costs, not just a gut feel. If you’re quoting jobs and wondering whether you’re making money or just staying busy, that’s where to start.

What Rate Should You Actually Be Charging?

Here’s a reality check based on what we see across Australian trades. If you’re a suitably qualified tradesperson working as a subcontractor — electrician, plumber, carpenter, HVAC — and you’re not charging at least $75–90/hr in most metro markets, you’re probably underpriced once you account for all your costs.

The casual loading rate (typically 25%) exists on employment contracts for a reason: casual workers don’t get leave, sick pay, or the security of ongoing employment. ABN work is effectively the self-employed version of casual — and your rate needs to reflect that.

If you jumped from a $35/hr wage job to $50/hr on your ABN because it felt like a pay rise, go back and run the numbers. After super, leave, insurance, and income gaps, you may have taken a cut.

Run Your Numbers Before You Commit

Whether you’re thinking about going out on your own, comparing a subcontractor offer to a full-time gig, or just trying to figure out if you’re charging enough — the answer is always in the numbers, not the gut feeling.

Use the Subby to Salary Calculator to convert your ABN income to a true wage equivalent, or head to the Advanced Tradie Calculator to build out your full charge-out rate from the ground up. Five minutes with the right tool beats five years of undercharging.

Know your number. Charge it. Build from there.
