Setting Your Labour Rate in NZ

The right charge-out rate isn't just your wages — it must recover all your costs and leave a profit.

The Cost-Plus Formula

Charge rate = (Actual wage cost × overhead factor) ÷ billable hours ratio

For a tradesperson earning $50/hr actual cost, with 25% overhead and 75% billable time:

($50 × 1.25) ÷ 0.75 = $83/hr minimum charge-out

Overhead Items Often Missed

  • Vehicle (loan, insurance, WoF, fuel, registration)
  • Tools and equipment
  • Software (job management, accounting, invoicing)
  • Mobile phone
  • ACC employer levy
  • Public liability and business insurance
  • Downtime (rain days, travel, quoting, admin)
  • KiwiSaver contributions
