NZ Employer Cost of an Employee Calculator 2026/27

This calculator works out what an employee genuinely costs your business in New Zealand, not just their gross salary, but every dollar layered on top of it. Enter the employee's annual gross salary, choose the KiwiSaver employer contribution rate you pay (the 3.5% default from 1 April 2026, or a higher rate up to 6%, or 0% if they are not enrolled), pick an industry risk category for the ACC Work levy per $100 of payroll (office, retail, manufacturing, healthcare, construction or forestry, or enter your own custom rate from your ACC invoice), and add any extra overhead such as equipment, software or training. The calculator returns a full breakdown: the KiwiSaver contribution, the ESCT payable on that contribution at the correct tax tier, the ACC Work levy plus the flat Working Safer levy added automatically, your overhead figure, and the total annual cost to the employer alongside the loading percentage above gross salary. It also shows a true hourly cost based on roughly 230 productive working days a year after leave, and a cost ratio explaining how that compares with the salary alone, useful for setting client billing rates or comparing employee against contractor costs. Check your own ACC Classification Unit rate before relying on the figures. Results are estimates for budgeting and hiring decisions, not a substitute for payroll or accounting advice.

Employee details

$

ACC employer levy

Find your exact CU rate on your ACC invoice. Working Safer levy ($0.08/$100) is added automatically.

Optional overhead

$
Indirect annual cost of supporting an employee: laptop depreciation, software licenses, training, desk space allocation. Conservative typical range: $2,000-$5,000.

Why employees cost more than their salary

An $80,000 salary doesn't cost you $80,000. The total annual cost to the business is closer to $88,000-$92,000 depending on industry and KiwiSaver participation, plus indirect overheads. Understanding your true cost is essential for setting client billing rates (consultancies typically need 2.5-3x salary as billing rate to be profitable), budgeting hires, and comparing employee vs contractor decisions.

The components

KiwiSaver employer contribution (3.5% from 1 April 2026)

You must contribute the default 3.5% on every dollar of gross salary for any KiwiSaver-enrolled employee not on a contributions holiday. Many employers contribute more (4%-6%) to attract talent.

ESCT on KiwiSaver contributions

You pay Employer Superannuation Contribution Tax on the KiwiSaver contribution you make. Rate is based on the employee's prior year earnings plus expected employer contributions: 10.5%, 17.5%, 30%, 33% or 39%. ESCT is deductible for income tax purposes.

ACC Work levy + Working Safer levy

The Work levy varies massively by industry (Classification Unit). Office work: ~$0.10 per $100. Construction: $2-$5 per $100. Forestry: can exceed $5 per $100. The Working Safer levy is a flat $0.08 per $100 across all industries.

Leave entitlements (already in salary)

Annual leave (4 weeks minimum) and sick leave (10 days from day one of employment) accrue throughout the year. These are already included in the gross salary you pay, but they reduce productive working days from 260 to about 230, effectively raising the per-productive-day cost.

Frequently asked questions

What is the true cost of an employee in NZ?

The true cost is significantly higher than the gross salary. For an employee on $80,000 gross with default KiwiSaver, expect approximately: $80,000 gross + $2,800 KiwiSaver employer (3.5%) + $840 ESCT on the KiwiSaver + ACC employer levy (varies by industry, typically 0.5%-3% of payroll) + holiday pay accrual already in the salary. Total typically 8-15% above gross depending on industry classification and benefits offered.

How is ESCT calculated for KiwiSaver employer contributions?

ESCT (Employer Superannuation Contribution Tax) is paid by the employer on top of the KiwiSaver contribution they make. The rate depends on the employee's prior year earnings PLUS expected employer KiwiSaver contributions: 10.5% (under $18,720), 17.5% ($18,721-$64,200), 30% ($64,201-$93,720), 33% ($93,721-$216,000), 39% (over $216,000). For a $80k employee, ESCT is 30% on the $2,800 employer contribution = $840. ESCT is a tax-deductible expense for the business.

What is the ACC Work levy?

The ACC Work levy is paid by employers based on their industry Classification Unit (CU) and total payroll. Rates vary widely: low-risk office work might be $0.10 per $100 of payroll, while high-risk industries like construction or forestry can exceed $5 per $100. The Working Safer levy ($0.08 per $100) is also payable by all employers. ACC invoices these levies annually based on the prior year's payroll.

Is KiwiSaver mandatory for employers?

Yes for eligible employees. Employers must contribute the default 3.5% (from 1 April 2026, was 3% before) for any employee who is enrolled in KiwiSaver and not on a contributions holiday. Some employees may not be eligible (under 18, over 65 with no longer required to contribute, on certain visas). Employers can voluntarily contribute more. The employer contribution attracts ESCT which the employer pays on top.
