The Retirement Income Simulator is an industry-leading retirement income calculator, which enables you to estimate your projected retirement savings and how long it may last in retirement.

The simulator is designed to estimate your total retirement income, including benefits you may receive from NZ Super and other investments. You can also choose to factor in retirement savings details for your spouse or partner (if applicable) and see the impact of a career break or move to part-time work on your projected retirement savings. This enables you to more clearly assess your estimated financial position in retirement and what you may need to do to reach your desired retirement balance.

This simulator does not know the future

The simulator cannot take into account changes in your personal circumstances, actual future investment returns, inflation or future changes to NZ Super and tax regulations.

Reasonable long-term assumptions have been made

The simulator uses default assumptions about future investment returns and inflation which are considered reasonable at the current date based on long-term economic modelling (by Mercer Investment Consulting). You can modify these assumptions.

Results are in today's dollars

Showing results in today's dollars allows you to consider your future retirement income in the context of the cost of today's goods and services and your current standard of living.

The 'today's dollar amounts' have been calculated by deflating the projected dollar amounts based on the rate of wage inflation of 3.2%.
