How it works & common questions
Turn a someday goal into a monthly plan.
Start with a target and a timeframe. The calculator finds the end-of-month contribution needed to bridge the gap between what you have and what you want, allowing for a constant interest rate.
How this calculator works
We project your starting balance over the selected term, then calculate the monthly contribution needed to make up the rest. At zero interest, the remaining gap is simply divided by the number of months. If your existing balance is enough, the required contribution is zero.

A few good questions.
Can I use this for a home deposit?
Yes. Set your target to the deposit plus a separate allowance for purchase costs. This tool does not estimate transfer duty, eligibility for grants, mortgage insurance or the amount a lender will approve.
What if my rate changes?
Try a lower rate as well as your expected rate. The model holds the entered rate constant, so it is useful for comparing scenarios, not predicting future bank offers.
Why does the result say I need no extra deposits?
Your starting savings, with the interest rate and time you entered, already reach the target in the model. Check that the assumptions are realistic and that your savings are available for this goal.
