Not all job offers are equal, even when the salaries look similar. A $5,000 salary difference is worth far less than $5,000 after tax. A better employer KiwiSaver rate can add thousands to your retirement fund every year. Extra leave days, health insurance, and vehicle allowances all have real dollar values that most comparison tools miss entirely. This calculator converts every component of two job offers into true after-tax cash equivalents so you can see which package is genuinely worth more.
Enter the details for each offer below, along with your personal KiwiSaver and student loan settings, and the calculator will apply full 2026/27 IRD PAYE rates, ACC levy, ESCT, and IETC to produce a complete side-by-side comparison.
Two job offers can have the same headline salary but deliver very different real value. The most common differences come from employer KiwiSaver rates, taxable allowances, non-cash benefits, and leave entitlements - all of which have real dollar values that affect your financial position but don't appear in the salary number.
Because New Zealand uses a progressive tax system, salary differences are worth less after tax than they appear. A $5,000 raise for someone earning $75,000 falls in the 33% bracket, meaning you only keep $3,350. Understanding the after-tax value of each component helps you negotiate more effectively and make genuinely informed decisions.
Employer KiwiSaver contributions go directly into your retirement fund - they do not appear in your take-home pay but they are real value you receive. The minimum employer contribution from 1 April 2026 is 3.5%. However, some employers offer 4%, 5%, 6% or more.
The difference compounds significantly over time. On a $90,000 salary, the difference between a 3.5% and a 6% employer KiwiSaver rate is $2,250 per year going into your retirement fund. Over 20 years with typical growth, this difference alone can represent over $100,000 at retirement.
Employer KiwiSaver contributions are subject to ESCT (Employer Superannuation Contribution Tax), which is deducted from the contribution before it reaches your fund. The ESCT rate is based on your total annual income plus employer contributions, using the same thresholds as the income tax brackets.
Each additional day of annual leave above the standard 20 days is worth your daily rate. On a $75,000 salary with 260 working days per year, one extra leave day is worth $288. Five extra days is worth $1,442 - more than many people realise. When comparing offers with different leave entitlements, this calculator converts extra leave days into an annual dollar value using your base salary.
Vehicle allowances, phone allowances, and other regular cash allowances paid by your employer are treated as taxable income for PAYE and ACC purposes. This means a $5,000 vehicle allowance does not add $5,000 to your take-home pay - it adds approximately $2,900 to $3,350 depending on your tax bracket. This calculator includes all cash allowances in your taxable income calculation so you can see their true after-tax value.
Employer-paid health insurance is generally treated as a fringe benefit for tax purposes, meaning it is not included in your PAYE taxable income. The value of health insurance varies widely across New Zealand employers, typically ranging from $500 to $3,000 per year for individual cover. This calculator includes health insurance as a benefit value in your total package comparison without applying income tax to it.
