How to Calculate Your Charge-Out Rate as a Builder

23 May 20267 min read

Ask 10 builders what their hourly charge-out rate is and you will get 10 confident answers and maybe 2 correct ones. Most blokes pick a number that sounds about right, or they match what the last bloke charged, or they are still using the rate they set when they went out on their own years ago. Then they wonder why they are flat out and still skint.

Your charge-out rate is the foundation under every quote you write. Get it wrong and everything built on top of it leans, no matter how sharp your subbie quotes are or how tight you run the site. This is the number I fix first with almost every builder I work with, because once it is right, a lot of other problems quietly sort themselves out.

What a charge-out rate actually is

Your charge-out rate is not your wage divided by your hours. It is the price you need to charge for an hour of productive labour so that, once everything is paid, the business is still standing and you have taken home a proper wage.

"Everything" is the bit people miss. Your rate has to carry:

  • Your wage, the real one, not what is left over.
  • Super on that wage.
  • Annual leave you actually take, plus public holidays.
  • Sick days, because you will have them.
  • Workers comp and the rest of your insurances.
  • Your vehicle, fuel, tools, and tool replacement.
  • A share of every overhead the business carries: office, phone, software, accounting, marketing, the lot.

And here is the kicker that catches everyone: all of that has to be recovered across the hours you can genuinely bill, not the hours in the calendar.

The hours nobody counts

There are 2,080 working hours in a standard year if you do 40 a week for 52 weeks. You will not bill anywhere near that.

Take out 4 weeks annual leave, the public holidays, a handful of sick days, and you are already down around 230 hours before you start. Then take out the hours you spend quoting, chasing materials, doing the books, driving between sites, meeting clients, and standing on site supervising work you are not directly billing for. For a lot of working builders, genuinely billable hours land somewhere around 1,200 to 1,400 a year, not 2,080.

This is the single biggest reason charge-out rates come out too low. Builders spread their costs across 2,080 hours when they can only bill 1,300. That gap, the difference between hours worked and hours billed, has to be carried by the hours you do bill. Ignore it and you are effectively working a chunk of the year for free.

The maths, step by step

Here is the sequence I walk builders through.

1. Start with your target wage. What do you actually want to take home? Not survive on, take home. Say you decide on a number that pays the mortgage and lets you breathe. 2. Add your on-costs. Super, leave loading, workers comp. These are a percentage on top of the wage, and they are real money leaving the business. 3. Add your share of overhead. Total up everything the business spends in a year that is not a direct job cost: vehicle, insurances, office, phone, software, accounting, marketing, your own training. That is your overhead pool. 4. Divide by your real billable hours. Take the wage plus on-costs plus your share of overhead, and divide it by the genuinely billable hours you worked out above, not the calendar hours.

The number that falls out is your charge-out rate: the minimum you need to charge per productive hour just to break even on your own time. Margin sits on top of that, it is not baked into it.

When builders run this for the first time, the rate is almost always 20 to 40 percent higher than what they have been charging. That gap is exactly why the bank balance never moves.

Why "the bloke down the road charges X" is a trap

The most common way builders set a rate is by looking sideways at what someone else charges. The problem is you have no idea what is going on inside that bloke's business. He might be running it into the ground. He might have no overhead because he works out of his garage and his wife does the books for free. He might be subsidising the rate with savings and not even know he is losing money. Copying his number copies his mistakes.

Your rate is yours. It is built on your costs, your overhead, your wage, and your real hours. Two builders on the same street can have legitimately different rates and both be right, because their businesses are different. Set yours from your own numbers, not the rumour mill.

How the rate feeds your quotes

Once you know your true rate, quoting gets a lot less stressful, because you are no longer guessing whether the labour line covers you. You know it does. This is why the charge-out rate is the first link in the chain I lay out in the guide on pricing a custom home build, the foundation that the margin, the contract, and the quote all build on.

It also changes how you handle the small stuff. When you know an hour of your time genuinely costs what it costs, you stop doing "quick" jobs and minor changes for free, because you can see the money walking out the door. That feeds straight into managing build variations properly, where a clean rate means you can price a change in 2 minutes without second-guessing yourself.

And if your jobs keep finishing thinner than you quoted despite tight sites and good subbies, an undercooked charge-out rate is one of the first leaks to check. The post on why your quotes keep losing money walks through the rest, but a wrong rate is often the one bleeding the most.

Get the number, then pressure-test it

The quickest way to do this is the Charge-Out Calculator. Put in your target wage and your real billable hours and it does the on-costs and overhead maths for you, so you are not building a spreadsheet from scratch. It is free and it lands in your inbox.

Work out your number, then look at what you have actually been quoting. If there is a gap, that gap is the money you have been leaving on every job. If you want help closing it without scaring off clients, the free numbers check is where I sit down with your real figures and we work out how to charge what you are worth and still win the work.
