Step 1

Tell us about your household

Answer a handful of simple, plain-English questions about income, savings, debts, and spending. Singles and couples are both supported, and you can finish in about five minutes.

Step 2

See your Base Case instantly

We turn your answers into a 50-year net-worth and cashflow forecast, complete with NZ Super, taxes, and spending projections. You immediately see whether you are "on track," "review," or "take action."

Step 3

Explore what-ifs

Want to retire early, take a sabbatical, or model a windfall? Duplicate your Base Case, change one or two assumptions, and compare outcomes side-by-side. Pro unlocks Monte Carlo confidence bands, and Parker AI lets you explore scenarios conversationally.

Step 4

Adjust anytime

Update onboarding inputs and tweak scenarios whenever life changes. Free includes one Monte Carlo preview run, and Pro unlocks unlimited reruns. Everything recalculates automatically, so you always know where you stand.
