Redundancy vs New Job Calculator

This calculator helps you weigh up whether to stay on for a redundancy payout or leave sooner to start a new job. Redundancy payments are taxed as income on top of your existing pay, so the headline payout overstates what actually lands in your account, and this tool corrects for that. You enter your gross redundancy payout, your current salary, the salary on offer in the new role, and how many weeks sooner you could start if you walked away early. From those figures it works out the after-tax payout you would receive by staying, and the extra net pay you would earn by starting the new job that many weeks sooner, using current New Zealand tax brackets and the ACC earner levy. It then gives a clear verdict on which option leaves you better off in money terms alone. Use it to sense-check an offer before you hand in your notice, or to see how much extra salary or head start a new role would need to beat the payout you are due. Because a decision like this is rarely only about money, weigh up job security, the strength of the new opportunity, how long a job search might realistically take, and your own wellbeing too. Figures are indicative estimates based on current tax settings and are not financial advice.

Both figures are after tax on the 2026/2027 brackets (ACC earner levy 1.75%). The payout is taxed on top of your income. This is a money comparison only; weigh job security, prospects and wellbeing too. Estimate only, not financial advice.

How it works

The calculator taxes the redundancy payout on top of your current income to find the net payout you would receive by staying. It then works out the net pay you would earn in the new role over the weeks you could start sooner, less the net pay you would have earned staying put. Comparing the after-tax payout with that extra net pay shows which choice leaves you better off over the period.

Worked example

A $20,000 payout taxed on top of $75,000 nets roughly $13,400. Starting a $85,000 role 12 weeks sooner, instead of the $75,000 role, earns a small amount of extra pay, so the larger payout wins on money alone here, though a much higher new salary or longer head start could tip it the other way.
