Charge-Out Rate CalculatorThe number you should be charging, worked out properly rather than guessed.
The charge-out rate calculator for Australian and New Zealand trade businesses. Put in what labour really costs you, how many hours you can actually invoice and what the business spends, and it builds the rate that covers all of it and still leaves a margin. Everything is worked out in your browser and nothing you type is sent anywhere.

Why your rate is probably wrong
Sound Familiar?
Your rate came from asking around
You picked a number years ago because it sounded about right for your area, or because it was a bit under the bloke who kept beating you on price. It has never been built up from a wage, an on-cost, a vehicle or an hour, and it has never been rebuilt since.
You pay for hours nobody ever invoices
Driving between jobs. Quoting on a Sunday. Chasing materials the wholesaler got wrong. Going back to fix something. Every one of those hours is paid for and none of them reaches an invoice, and almost no owner can tell you how many there were last year.
The busiest year you have had, and nothing in the bank
Turnover went up, the crew grew, the diary was full for eleven months, and the account looks the same as it did in January. So you assume it is a cash flow problem, or a tax problem, and price the next job the same way you priced the last one.
Underpricing never arrives as a loss. It arrives as a full diary, a tired body and a bank balance that will not move, and it can do that quietly for years.
The calculator
Work Out Your Real Charge-Out Rate.
Nine numbers, and you have most of them in your head already. Change anything and the rate moves as you type. It all happens in your browser, so nothing you put in here goes anywhere.
The figures it starts with are round examples so the tool works the moment you land. Replace every one of them with your own.
The working
- Wage plus on-costs, per person
- $100,000
- Paid hours, per person, per year
- 1,748
- Hours you can invoice, per person
- 1,311
- Paid hours nobody invoices
- 437
- Labour, per billable hour
- $76.28
- Overheads, per billable hour
- $45.77
- Break-even rate
- $122.04
- Margin inside the rate
- $21.96
- The same rate as a markup on cost
- 18%
The rate is rounded up to the whole dollar, because a price rounded down misses the margin it was built to protect. Every figure here is worked out in your browser. Nothing you type is sent anywhere, stored or logged.
The formula
The Charge-Out Rate Formula, Step By Step.
This is what the calculator is doing. Work it on paper if you would rather, or use it to check a number your accountant gave you.
Work out what labour really costs
Take the annual wage for one person on the tools and add on-costs: superannuation, workers compensation, allowances and leave loading. The wage on its own is the smallest part of the number, which is why a rate built off a wage never holds.
Work out how many hours you can actually invoice
Multiply the weeks each person really works, after annual leave, public holidays and sick days, by the paid hours in a week. Then take the share of those hours that reaches an invoice. Travel, quoting, chasing materials, yard time and going back to fix something are all paid for and none of them is billable.
Divide labour cost by billable hours, not paid hours
This is the step that decides whether the rate is right. Dividing by paid hours gives you the cost of employing somebody, which is a payroll figure and not a price. Every paid hour that never reaches an invoice has to be carried by the hours that do.
Add overhead recovery per billable hour
Take everything the business spends that is not a person on the tools: vehicles, fuel, insurance, licences, rent, phones, software, accounting, marketing, tools and office wages. Divide it by the billable hours of everyone on the tools. Overheads have to be carried by billable hours because there is nothing else to carry them.
Divide by one minus your margin
Labour plus overhead is your break-even rate: charge it and the business makes exactly nothing. To leave a fifteen per cent margin, divide the break-even rate by 0.85. Do not add fifteen per cent, because adding fifteen per cent to cost leaves about thirteen per cent of the price. That is the difference between a markup and a margin.
Worked through, end to end
One person on the tools on $80,000 a year, plus 25 per cent on-costs, costs the business $100,000. At 46 weeks of 38 hours they are paid for 1,748 hours, and at 75 per cent billable only 1,311 of those hours ever reach an invoice. So 437 paid hours a year have to be carried by the ones that do, which puts labour at $76.28 a billable hour rather than the $57.21 a payroll report would suggest.
Add $60,000 of overheads across those same billable hours, at $45.77 an hour, and the break-even rate is $122.04. Charge that and the business makes nothing at all. Divide it by 0.85 to leave a 15 per cent margin and the rate is $144 an hour, before GST. Those are round example figures, not a benchmark. Put your own in above.
Worth knowing
Why The Number Moves Every Year.
Australian employers must pay superannuation guarantee contributions on top of ordinary time earnings, so a wage is never the full cost of an hour of labour.
Minimum pay rates for most Australian construction and trade employees are set by a modern award and reviewed every year, so a charge-out rate built once will fall behind its own labour cost.
What to do with the number
A Rate You Cannot Hold Is Just A Number.
Working out the rate takes two minutes. Quoting it to a builder who says everyone else is cheaper, and not blinking, is the part that takes training. That is the part we do.

Apprentice cost calculator
This page works out what an hour has to be sold for. That one works out what an hour of an apprentice actually costs you, once you count the weeks at trade school, the on-site hours that never reach an invoice, and the supervision time that pulls a qualified tradesperson off their own work. You need the rate above to price that supervision honestly. Same rules: it runs in your browser and nothing you type is sent anywhere.
