Charge Out Rate Calculator: Work Out What You Should Actually Be Charging

If you’re quoting jobs based on gut feel or what your mates charge, you’re probably leaving money on the table — or worse, you’re pricing yourself into a slow bleed. A charge out rate calculator takes the guesswork out of it. You put in your real costs, your target income, your overheads — and it spits out the number you actually need to be hitting to run a profitable trade business.

This guide breaks down how charge out rate calculators work, what inputs actually matter, and the mistakes most tradies make when setting their rate.

What Is a Charge Out Rate, and Why Does It Matter?

Your charge out rate is the hourly rate you bill clients for your labour. It’s not your take-home pay. It’s not your base wage. It’s the number you need to charge to cover all of this:

• Your own labour cost — what you’d need to pay yourself to do the work
• Business overheads — insurance, tools, vehicle, phone, software, accounting
• Non-billable time — quoting, travel, admin, sick days, public holidays
• Superannuation — if you’re not on a payroll, you’re still responsible for it
• Tax — the ATO doesn’t care that you forgot to save for it
• Profit margin — the bit that actually builds the business

Most tradies set their rate by looking at what competitors charge and pricing slightly under to win work. That’s a race to the bottom. The correct method is to calculate what you need to charge, then assess whether the market will bear it.

How a Charge Out Rate Calculator Works

A proper charge out rate calculator — not a generic wage calculator — will ask for:

• Target income: What you want to take home after tax
• Billable hours per year: Not 52 weeks × 40 hours. More like 45 weeks × 32–35 billable hours once you strip out quoting, travel, admin, sick leave, and public holidays
• Annual overhead costs: Vehicle, tools, insurance, phone, software — everything you spend to operate the business
• Superannuation: Currently 11.5% (as of 1 July 2024)
• Tax provision: Based on your expected taxable income
• Profit margin: Typically 10–20% on top of break-even costs

Add that all up, divide by your billable hours, and you get a real charge out rate. Not a number pulled from thin air — an actual figure you can stand behind when a client pushes back on your quote.

The Boss Tradie Advanced Tradie Calculator walks you through this entire process — overhead allocation, tax estimate, profit margin — in one place. Run it before your next job and see where you actually sit.

The Billable Hours Problem (Most Tradies Get This Wrong)

This is where most charge out rate calculations fall apart. A tradie assumes they can bill for 40 hours a week, 52 weeks a year. That’s 2,080 hours. In reality?

• 4 weeks annual leave = 160 hours gone
• 10 public holidays = 80 hours gone
• Sick leave (realistic average) = 40 hours gone
• Quoting, admin, travel between sites = another 6–10 hours a week minimum

You’re looking at roughly 1,100–1,300 truly billable hours per year for a sole trader who handles their own quoting and drives between jobs. If you’ve been calculating your rate based on 2,080 hours, your rate is too low — possibly by 30–40%.

That’s not a rounding error. That’s the difference between a growing business and one that’s slowly bleeding while you’re too busy to notice.

Subcontractor vs Employee: Why the Numbers Are Different

If you’re comparing your ABN hourly rate to what an employed tradie takes home, you’re comparing apples to oranges. As a contractor, your charge out rate needs to cover everything an employer used to pay on top of wages:

• Superannuation (11.5%)
• Workers’ compensation insurance
• Leave entitlements — even if you’re not technically getting them, you’re absorbing the risk of downtime
• Public liability insurance
• Tool and vehicle depreciation

This is exactly what the Subby to Salary Calculator is built for. If you’re trying to work out whether your sub rate is equivalent to a fair salary — or what salary you’d need to match what you’re currently making on an ABN — it translates the numbers so you’re comparing like with like. Run it before accepting your next sub rate. You might be surprised at what it actually works out to.

When to Review and Adjust Your Charge Out Rate

Your rate isn’t something you set once and forget. Review it at minimum once a year, and immediately when any of these change:

• Materials costs increase: If what you’re buying costs more, your margin takes the hit unless you adjust
• You take on an employee: Your overhead structure changes significantly when you add payroll costs
• Super rate increases: Legislated Superannuation Guarantee increases affect your real cost of employment
• Fuel or vehicle costs shift: A ute costing $800/month to run in 2023 might be costing $1,100/month now — that gap has to come from somewhere
• Your work mix changes: Moving from residential to commercial, or from maintenance to new builds, changes your job profile and billable hours assumptions
• Inflation erodes your margin: Even if nothing specific changes, CPI running at 4–5% means your real margin shrinks each year unless you raise your rate to match

Common Mistakes When Setting Your Rate

Not including a profit margin

Labour cost plus overheads equals break-even. That’s not a business — it’s a job with extra admin. You need margin on top of costs so the business itself generates a return, not just wages. Without it, one slow month or one bad debt wipes you out.

Underestimating overheads

Most tradies undercount their annual tool spend, licensing fees, professional memberships, software subscriptions, accountant fees, and phone costs. Write out every dollar you spend to operate for a year. The total usually surprises people.

Confusing GST with income

If you’re registered for GST, the 10% you’re collecting isn’t yours — it’s the ATO’s. Your charge out rate is the ex-GST figure. Don’t muddle gross invoiced rate with net charge out rate when you’re running the maths.

Chasing the cheapest rate to win work

Clients who choose you purely on price will leave you for someone 5% cheaper next time. Build your rate on your actual numbers. The right clients will pay a fair rate — and they’re better clients to work for.

Typical Charge Out Rates for Australian Tradies (2026)

These are rough ex-GST ranges as a reality check — not a substitute for running your own numbers:

• Electricians: $90–$145/hr
• Plumbers: $85–$135/hr
• Carpenters and builders: $75–$120/hr
• Concreters: $70–$115/hr
• Painters: $65–$100/hr
• HVAC/refrigeration mechanics: $95–$150/hr

Rates vary by state, metro versus regional, and the complexity of work. Use these as a benchmark only. Your actual charge out rate needs to come from your own cost structure — not someone else’s.

Stop guessing. The numbers exist — you just need to run them properly.

Use the Boss Tradie Advanced Tradie Calculator to build out your charge out rate from your actual costs. It takes around five minutes and will tell you clearly whether your current rate is covering you — or whether you’ve been quietly subsidising your clients.

If you’re working on the tools as a subcontractor and want to understand what your ABN rate actually translates to in salary equivalent terms, start with the Subby to Salary Calculator. Then run your charge out rate check against your real overhead structure.

The numbers don’t lie. Your quote prices should reflect them.
