How to read the calculator
Cost per paid hour is the cleanest hourly employer number. It divides total employee cost by the paid hours entered. It does not guess productivity, mistakes, meetings, or training time.
Employee cost per week is useful for roster planning. For hourly workers, it is based on the weekly hours you enter plus the employer costs that apply. For salary mode, it spreads the annual cost across 52 weeks.
ACC Work levy defaults to the 2026/27 average Work levy of 0.69%. ACC varies by industry, so replace this if you know your classification rate.
KiwiSaver is included only when the employee is in KiwiSaver and employer contributions apply. If the employee has opted out or is not eligible, choose that option and the employer KiwiSaver cost becomes zero.
When to use each input
Use hourly wage for minimum wage, retail, hospitality, support, admin, and rostered roles. Use annual salary for salaried positions where the employer thinks in yearly cost first.
Use extra annual employer costs only for costs you can estimate, such as recruitment, training, payroll/admin, equipment, tools, or uniforms. The calculator does not invent these costs for you.
