Property deposit goal calculator
See the monthly savings needed to reach a home deposit target from a price and deposit percent.
What the result means
A deposit goal is a dollar target taken from a price and an LVR plan, then funded with monthly savings.
How it is calculated
Target = price × deposit %. Then solve monthly PMT for that target
- Years: How long you will save before buying.
The deposit dollar amount is the savings-goal target. Monthly deposits compound at the rate you enter.
Assumptions
- Estimates only — not tax, legal, credit or financial advice. Check the official source or your contract before relying on a figure.
- Fixed price, fixed rate, no grants or stamp duty.
Worked example
20% of $850,000 in five years
$40,000 already saved.
- Target
- $170,000
- Gap
- $130,000 plus interest earned on the way
The monthly figure is what fills that gap if the rate holds.
Prices move while you save
Five years of 4% savings interest does not help if prices rise faster. Revisit the target price. Grants and stamp duty concessions are jurisdiction-specific and omitted here.
Most of a two- or three-year target is deposits, not interest. Run the same goal at 0% first so you can see the gap that compounding is supposed to fill. Then add a conservative savings rate rather than a share-market return.
Questions
Should I include stamp duty in the target?
Yes if you will pay it in cash at settlement. Add it to the property price mentally or raise the deposit percent until the dollar target covers both.
What if house prices rise while I save?
Raise the target price and run it again. A deposit that was 20% of last year’s price can be 17% of this year’s, which is how LMI reappears after two years of saving.
