A practical guide to charge-out rates, margin, overhead recovery, and why the cheapest hourly number is rarely the safest business model.
Key Takeaways
Charge-out rates are one of the fastest ways a building business can either protect margin or quietly bleed. The mistake is treating the rate as a wage with a little extra added on. A proper rate needs to recover the cost of being in business.
Start with the real annual cost of each person or crew: wages, holiday pay, ACC, insurance, vehicles, tools, phones, training, admin, supervision, quoting time, rework allowance, and the owner's profit target. Then divide that by realistic billable hours, not the number of hours in a calendar year.
The utilisation number matters. If a carpenter is paid for forty hours but only thirty are recoverable after weather, travel, supplier runs, meetings, and admin drag, the charge-out rate has to carry the missing ten hours. Ignoring that gap is how a busy month still turns into a poor one.
Builders should separate labour rate, margin, travel, and specialist costs in their own internal model even if the client-facing quote is packaged. That makes it easier to see what is actually making money.
A good pricing review does not need to be complicated. Pull three finished jobs, compare quoted labour against actual labour, check vehicle and supplier run time, then update the rate or allowances before the next quote goes out.
The goal is not to become the most expensive builder in the market. It is to stop letting unpriced overhead decide whether the job was worth doing.
“The rate sounds high until you add the van, tools, insurance, downtime, quoting, callbacks, and the days you are not actually billing.”
Quotes are anonymised and lightly edited to remove identifying details while preserving the builder voice and practical context.
Usually not as the main sales message. A visible rate can help with transparency, but most residential jobs are judged on scope, programme, trust, and exclusions. Builders should know their internal rate even when quoting fixed-price or staged work.
At least quarterly, and whenever wages, vehicle costs, insurance, rent, software, or fuel move materially.
