Are these tools personalised financial advice?
No. These tools provide general estimates based on the information you enter. Personalised advice considers your full circumstances, goals, and risk profile.

A recent KiwiSaver statement, a list of key assets and debts, approximate income and expenses, and any existing insurance policies are a helpful start.
