Frequently asked questions

Can it model an offset account and extra repayments?

Yes. You can add an offset balance and extra or lump-sum repayments and see the effect on your payoff date and total interest immediately.

Does it work for an existing loan, or only a new purchase?

Both. Enter a new purchase or your current loan balance, rate and term, and it models either.

Can I compare what-if scenarios?

Yes, model a rate rise, a lump sum, or switching to fortnightly repayments and see the difference side by side, instantly.

Is my financial information private?

Yes. Your numbers stay on your own device (downloaded version) or in your account (online). We don't see or store your loan details on our servers.

Does it work offline?

Yes, the downloaded version runs entirely in your browser with no connection needed.

Is there a subscription?

No subscription for the downloadable version, it's a one-off purchase. Cloud sync across devices is available online for a small yearly fee if you want it.
