CPIplus’ return objective is set in advance for each return period (currently 12 months from 1 July). It is calculated using the following formula: CPI + n.
CPI is based on the average Consumer Price Index rate for the last two quarters and is updated each quarter. ‘n’ is a predetermined rate of return that is compounded daily over the return period. We determine the rate of return each year as part of our annual investment strategy review. You can find the value of ‘n’, the CPI rate and the current return period in our CPI Rates document.
By setting a return above CPI, we ensure that returns are above the level of inflation. This minimises the impact of inflation on the real value of your investment returns.
Returns are credited each day. There is a minimum daily return floor of zero, which means that the CPIplus daily return will not be negative – even if the CPI rate for that period was negative or the underlying investments performed below expectations.
