Common Questions
What personal details do you need?
Just an email to save your progress. That's it. No name, no IRD number, no bank logins. You enter your own estimates, we never connect to your accounts or ask for sensitive identifiers.
Is this financial advice?
No. fidser. is an advanced forecasting engine, sophisticated calculators that model your retirement scenarios. We don't provide financial advice. Use it to explore possibilities, then consult a licensed Financial Advice Provider (FAP) for real decisions.
Can I just try it for free?
Yes, and Free isn't a trial. It includes a full base-case 50-year projection with NZ Super, PAYE + ACC tax estimates, and KiwiSaver modelling. You also get one Monte Carlo preview run. Pro is there when you want additional what-if scenarios and unlimited Monte Carlo reruns.
