Our new partnership with is bringing additional calculators constructed with the user's interests at the forefront.

They are in addition to our own proprietary tools, extending what is available.

The new range is from simple versions to full professional versions.

You can find them all here.

A mortgage calculator for professionals that can solve for payments, principal, term or rate.

A full function calculator that will display all the calculations and chart the results.

Work out what more you can borrow under the Reserve Bank's LVR rules and limits.

Bring together the financial implications of a transition between homes with this handy tool.

In addition, our library of calculators includes tools to work out the real cost of credit card debt if you only repay the minimum payment. And the real cost of personal loans, especially short-term personal loans. (Both are usually far higher than you would otherise assume from the stated interest rate.)

The library also includes our famous full-function term deposit and savings calculator, working out your actual after-tax return (and showing you exactly how it is calculated).

We will be adding additional tools during 2020, with many sourced from our partner at With their help, we are building a uniquely useful set of calculator tools.
