$1,000 at birth becomes $53,000 at 65.

NZ is talking about a KiwiSaver kick-start for every newborn. From age 16 a young person can add to it themselves. See what that looks like for your tamariki — including the difference between just the kick-start and a wee top-up alongside it.

The maths behind the headline

$1,000 invested at birth, compounding at 6.3% nominal for 65 years, reaches about $53,000 — the figure being cited in the policy debate. Long-run KiwiSaver growth-fund returns sit between 5–8% before tax and fees. This calculator uses 6.3% by default so the visible result matches the news. Adjust it if you'd rather be more conservative.
