Pay Rise Lifetime Value Calculator NZ
This calculator shows what a single pay rise is really worth once you account for the compounding effect it has over the rest of your working life. Because future percentage raises are calculated on your new, higher salary, a rise you bank today keeps paying you extra every single year until you retire, not just this year. You enter the size of the pay rise in dollars, how many years you expect to keep working, and the annual percentage raise you assume you will get from there on. The calculator then returns the total extra you would earn over your remaining career, what that figure would be if your pay never grew again, and the compounding bonus, the gap between the two that comes purely from raises building on the higher base. It is a useful way to see why negotiating hard for even a modest rise now can be worth tens of thousands of dollars more over a career than it first appears, and why accepting a lower offer costs more than the immediate difference suggests. The figures shown are gross, before tax, and are meant to illustrate the scale of the compounding effect rather than predict your exact future earnings, so treat them as an indicative estimate rather than financial advice.

How it works
The calculator starts with your pay rise as a higher base, then grows it by your assumed annual raise each year for the years left in your career, and adds up the extra you earn each year. Because each future raise is a percentage of the now-higher salary, the rise keeps paying off well beyond its first year. The difference between this total and the simple rise times years is the compounding bonus.
Worked example
A $5,000 rise with 25 years left, growing 2.5% a year, is worth around $170,000 over the remaining career, compared with $125,000 if it never grew. The extra roughly $45,000 is the compounding bonus from lifting your base today.
