How it works

See the impact before you decide

WhatIf is a decision simulator for New Zealand households. It answers one question — can I afford this, and what could it change — from your own numbers.

  1. Start from your own numbers

    Tell WhatIf your income, spending, savings, and any mortgage — in a short chat, not a long form. You only enter what the current question needs.

  2. See your freedom age

    WhatIf projects your finances forward and shows the age your savings could cover life without a wage, in today's dollars — with the assumptions on show, not buried.

  3. Ask “what if”

    Model a real decision — pay down the mortgage, save more, change jobs, buy something big, earn less — and watch your freedom age and the years ahead move. Nothing is calculated until you confirm your figures.

  4. Track how your plan moves

    Save a baseline and WhatIf remembers where your freedom age sat each time, so you can see how life's changes have shifted it. A quarterly check-in nudges you to keep the figures current.

Every figure comes from a deterministic engine, not a guess or a language model. Read how the numbers are worked out. WhatIf is a decision simulator, not personalised financial advice, and it does not recommend a specific product.
