Contractor Pay Calculator: What You Should Actually Be Charging as an Australian Tradie
Most tradies go out on their own and set their rate by guessing — they hear what mates are charging, add a bit on top, and hope for the best. That’s how you end up either leaving money on the table or pricing yourself out of work without knowing why.
A contractor pay calculator takes the guesswork out of it. Punch in your costs, your target income, and your working hours, and you get a number that actually makes sense. No more gut feeling. No more “I reckon $75/hr should be right.”
Here’s how to use one properly, what numbers to put in, and why getting this right matters more than most tradies realise.
Why You Can’t Just Copy What the Next Bloke Is Charging
It’s tempting to look at what the other subbies in your trade are asking and match it. The problem is you have no idea what their costs look like. They might own their ute outright. They might have a spouse pulling a wage. They might be quietly losing money every month and not know it yet.
Your rate needs to be based on your numbers:
- Your actual tool and equipment costs
- Your vehicle running costs (fuel, rego, insurance, maintenance)
- Your insurance premiums (public liability, income protection)
- Your super contributions — because nobody’s doing that for you anymore
- The weeks you WON’T be working (public holidays, leave, slow periods, wet weather)
- Your tax obligations as an ABN holder
- What you actually want to take home at the end of all that
When you add it all up through a proper subby to salary calculator, most tradies are shocked. The hourly rate that felt fine on a job site turns out to be the equivalent of a $55k salary after costs. That’s not what you signed up for when you went out on your own.
The Costs Most Tradies Forget to Include
Here are the big ones that don’t get factored in often enough:
Non-Billable Time
You don’t bill for every hour you work. Quoting, driving between jobs, doing paperwork, chasing invoices, picking up materials — none of that goes on a timesheet. A realistic contractor pay calculator assumes you’re billing maybe 6–7 hours out of an 8-hour day. If you’re pricing based on 8 billable hours, you’re already behind.
Super
As a subcontractor, super doesn’t come out of your pay automatically. It comes out of your pocket if you remember — and doesn’t come out at all if you don’t. That’s currently 11.5% of your intended income that needs to be built into your rate, not taken from it.
Tax
A lot of subbies invoice, get paid, and figure they’ll sort the tax out later. “Later” has a way of arriving ugly. Your contractor pay calculator should build in a tax buffer — roughly 25–32% depending on your earnings bracket. Set it aside weekly. Don’t touch it.
The Slow Weeks
You’re not going to bill 48 weeks a year. Realistically, factor in 44 billable weeks maximum — and that’s being optimistic. Public holidays, rain days, sick days, the slow patch in July. A contractor pay calculator that accounts for real working weeks (not calendar weeks) gives you a much more honest picture.
How to Actually Use a Contractor Pay Calculator
Our Advanced Tradie Calculator breaks it down step by step. Here’s the basic approach:
- Start with your target income. What do you actually want in your pocket at the end of the year? Not gross. Net. Be specific.
- Add your super. Multiply your target by 1.115 to account for 11.5% super on top.
- Add your tax buffer. Gross up by your estimated tax rate — use 28–30% as a starting point if you’re not sure.
- Add your direct costs. Vehicle, tools, insurance, phone, accountant, software. All of it.
- Divide by your real billable hours. Take your working weeks (aim for 44), multiply by your billable hours per day (use 6.5), and that’s your denominator.
The number you get is your minimum viable hourly rate. Anything below that and you’re going backwards.
Subby vs Salary: Why It Matters for Your Rate
If you came from a staff job, you might be thinking “I was on $42/hr employed, so $55/hr as a subby is a good jump.” Not necessarily.
As a staff employee, your employer was covering super, workers comp, annual leave, sick leave, and public holidays on top of your rate. That’s worth roughly 20–30% on top of your take-home. As a subcontractor, all of that is now your problem.
The subby to salary comparison isn’t about which number is bigger — it’s about understanding the real cost of each arrangement. A contractor rate calculator that shows you the equivalent salary comparison helps you see whether you’re actually better or worse off than your old job.

Day Rate vs Hourly Rate: Which Should You Use?
Once you know your minimum hourly rate, you can start thinking about how to present your pricing. Day rates have a few advantages:
- Clients don’t watch the clock as closely
- You’re not penalised for working efficiently
- Easier to quote and invoice
- Protects you when jobs take longer than expected
A day rate of 8 times your hourly rate is a reasonable starting point. So if your contractor pay calculator spits out $72/hr as your minimum, a $576 day rate (round up to $580 or $600) makes sense.
Some trades work better on a project rate — fixed price for the whole job. That’s fine too, but you need to be very accurate on your hours estimate, because there’s no buffer if you miscalculate.
What a Good Rate Looks Like in 2025
Without going into trade-specific detail (rates vary significantly by trade, state, and experience), here are some ballpark figures for what subbies are charging in Australia right now:
- Electricians: $85–$120/hr depending on licence level and state
- Plumbers: $90–$130/hr (higher in WA and QLD)
- Carpenters: $65–$95/hr depending on type of work
- Concreters: $55–$80/hr for labour-only work
- Painters: $55–$75/hr or more for specialised finishes
If your contractor pay calculator result is coming out significantly below these ranges, either your costs are unusually low (double-check) or you’re undervaluing your experience. If it’s above these ranges, that’s fine — you need to make sure you can justify the premium on-site.
Stop Guessing. Run the Numbers.
The best thing you can do for your contracting career is get honest about the numbers. Not optimistic. Not copy what the other bloke charges. Your actual costs, your actual target, your actual working weeks.
A contractor pay calculator gives you a defensible number — one you can explain to a client, stick to under pressure, and actually build a business around.
