About this calculator

What it does

TRP’s Retirement Planning Calculator forecasts how much you could have at retirement based on your continued contributions at the levels you have chosen, your fund type (s), and how far off your retirement is. It also provides an estimate of how long those funds will last in retirement based on the spending needs you estimate you will need.

Assumptions

The calculator assumes the following:
  • Inflation is 2%.
  • If you select Employed, the KiwiSaver calculation assumes your pay increases at 3.5% per year and that your contributions increase in line with your pay. For example, $200 today will be $230 in 4 years’ time. The assumed pay increase of 3.5% is included in the calculations by applying a margin to the assumed long-term rate of inflation (2%).
  • If you select Self-employed or Not working, the KiwiSaver calculator assumes that your contribution amount increases each year with inflation.
  • You do not suspend your savings at all.
  • You receive the same government contribution each year that you are currently receiving. These are included at the end of each member credit year which runs from 1 July to 30 June. (Note: To receive the full government contribution, you must be a KiwiSaver member for the entire year, from 1 July to 30 June. If you join KiwiSaver midway through the year, the partial amount you can get is prorated based on how long you’ve been a member.)
  • Your KiwiSaver and other investments are in a managed fund which is a portfolio investment entity (PIE). Your PIE income is taxed at either 28%, 17.5% or 10.5%, depending on your total taxable income.
  • Your net return from the managed fund will vary, depending on your type of fund and your PIE tax rate or prescribed investor rate (PIR). The assumed returns are:

10.5%

Calculator methodology

Adjusting for inflation

The total amount shown is the estimated funds you will have at the start of your retirement in ‘todays dollars’ (ie after adjusting for inflation at 2% pa.). For example, by the time you reach age 65 you might have a total retirement fund balance of $597,000. However, as the price of everything will have increased by that time, you would only be able to buy $271,000 worth of goods at today’s prices.

Results

The calculator results show the total sum you would have in your at retirement funds and how long these funds will last based on the estimated spending needs as a percentage of your current income.
Results are shown with the effect of 2% inflation. Results are also shown with your retirement years, and the effect of drawing down your retirement funds regularly over time.
