What does an employee really cost?
A wage is not what somebody costs. Add KiwiSaver, the levies an employer pays on top, and the hours you pay for but can't sell — then work out what an hour of their time is really costing you.
Why the wage is never the cost
Two separate things push the real number up, and they compound. Most people costing a hire miss both.
- Levies sit on top of the wage. KiwiSaver is the big one, and in most markets there's an employer payroll levy alongside it. Workers' compensation is compulsory everywhere and is charged as a percentage of what you pay out.
- You buy hours you can't sell. Annual leave, public holidays and sick days are all paid, and none of them can be invoiced. On a standard week that's around six weeks a year gone before anybody picks up a tool.
- The two multiply. A bigger annual cost divided by fewer sellable hours moves the hourly figure much further than either does alone — which is why the headline above is usually 30–40% above the wage rate people have in their head.
This is the number to price against, not the wage. If you're quoting a job at your own charge-out rate and paying somebody else to do it, the margin is the gap between that rate and this figure — not between it and their wage.
Before you take somebody on
The honest test isn't whether you can afford the wage. It's whether there's enough billable work to cover the number above, consistently, through a quiet month.
Work out your own charge-out rate first, then look at the gap. If an employee costs you $45 an hour and you can bill their time at $95, the difference has to cover their unbillable hours, your time supervising, and the overheads neither of you shows up in — before any of it is profit.
