What Is FIRE? How to Calculate Your FIRE Number in New Zealand
Calculate your FIRE number using real spending, accessible investments, KiwiSaver, NZ Super and housing, then turn the estimate into a practical NZ plan.
FIRE means building enough financial independence to choose how you spend your time — long before a traditional retirement age.
It is not one destination or one universal number. Your plan begins with the life you want and the choices you want money to make possible.

It is not about deprivation for its own sake. It is about aligning what you earn, save and invest with the freedom you actually want.
01
Increase the difference between what you earn and what you spend.
02
Invest consistently so your money has time to compound.
03
Shape the target around your lifestyle, timeframe and comfort with risk.
Your FIRE number is the portfolio your plan may need to support the way you want to live.
It changes with your spending, timeline, investments and withdrawal assumptions. There is no single magic multiplier that works for everyone.
Independence built around intentional spending.
More freedom with some flexible income.
A larger portfolio for a higher-spend lifestyle.
