The term portfolio refers to any collection of financial assets such as stocks, bonds, and cash. Portfolios may be held by individual investors and/or managed by financial professionals, hedge funds, banks and other financial institutions. It is a generally accepted principle that a portfolio is designed according to the investor's risk tolerance, time frame and investment objectives.

This calculator is a guide to help you design investment portfolios for five different levels of risk. They are designed to optimise the risk / return relationship, including currency considerations.

  1. These calculations are intended as a guide only and should not be relied upon without seeking professional advice.
  2. These are long term allocations and are not expected to change significantly from month to month or year to year.


Very low risk / Very Low Return

This portfolio is for people who are concerned about preserving their capital (in nominal terms) and are not concerned about the long term effects of inflation and taxation.  It is unlikely to retain its real value in the long term even if all after tax income is compounded, but is also unlikely to have negative returns over any period. Taxable income is likely to be high.

Low Risk/ Low Return

This is for people who are prepared to accept a small level of risk in exchange for higher long term returns. The total portfolio value is unlikely to fluctuate very much. If all income is reinvested the portfolio should just maintain its value in real terms. (After tax and inflation are taken into consideration). Small negative returns may be occur occasionally (every 4 to 5 years). Taxable income is likely to be moderately high.

Moderate risk / Moderate Return

A portfolio expected to grow in excess of the rate of inflation but with moderate fluctuations in value. This asset allocation is appropriate for a broad range of investors that can take a longer term view (4 years or more). It will be suitable for many who are saving for retirement. Taxable income is likely to be modest.

High risk/ High Return

The equity component of this portfolio is large and will cause substantial fluctuations in portfolio value from time to time. It is suitable for those who want after tax returns well in excess of the rate of inflation and who have a high tolerance for risk. Investors should have a medium term view exceeding 5 years.

Very High risk/High Return

This portfolio contains 100% equities, therefore it would be expected to achieve the highest after tax returns over the long term, but may also experience prolonged periods of negative returns. Portfolio values will have very high fluctuations. Expected income is low. Investors should have a medium to long term view of 7 to 10 years or more.
