KiwiSaver Temporary Rate Reduction Cost Calculator

This calculator shows what temporarily dropping your KiwiSaver contribution rate costs in New Zealand, the contributions you skip while reduced and what that money would have grown to by retirement. Reducing your rate is the middle path between contributing at your usual level and pausing altogether with a savings suspension. It eases the pressure on your take-home pay while still keeping something going into your retirement savings, and if you stay at or above the compulsory minimum your employer keeps matching, which a full suspension would stop. The cost is the difference between your old and new contribution for as long as you stay reduced, plus the investment growth that lost money would have earned over the years to retirement. You enter your salary, your usual rate and the reduced rate, the number of months you would stay reduced, the years until retirement and the return you expect, and the calculator works out the contributions you give up and their value at retirement. Use it to see the real cost of easing off, and to compare a smaller drop for longer against a bigger drop for a shorter time. Reducing is usually gentler than a full pause, but the growth you forgo still adds up over a long horizon. Returns vary; this is a projection, not advice.
