Deposit growth calculator

How long it could take to save your target deposit.

  • What it means

    This estimates how long it could take to save a target deposit from what you already have plus monthly saving.

  • Why it matters

    A clear timeline turns a vague goal into a plan, and shows whether you need to save more or aim for a lower price.

  • When to use it

    Use it when you are still saving, before you have enough for an offer, or when you change your monthly contribution.

  • How to read the result

    The months-to-target figure is the guide. House prices are held still here, so revisit the target if local prices move.

Your figures

Defaults to price times percentage.

Methodology

FAQs

Does this include property price growth?

No. The target price is held constant so you can see the saving path clearly.
