What does a negative legacy mean?

This means that based on the current financial circumstances (current investments, super contributions, savings, withdrawals and risk tolerance) the retirement income goal that is stipulated is too high. The user should observe the Retirement Income Vs Legacy trade off chart as a guide to what income and legacy outcomes are possible. Either adjust the retirement income goal, risk tolerances (certainty level or shot term fluctuations), increase super contributions or other savings or utilise home equity.
