Buying

Deposit calculator

How much cash deposit you need at common percentage levels.

  • What it means

    Your deposit is the cash chunk you put in when you buy. This shows how much that is at common percentage levels.

  • Why it matters

    A bigger deposit usually means a smaller mortgage and often a better rate. It also means more cash tied up on day one.

  • When to use it

    Use it when saving toward a first offer, or when comparing how much cash different price points need.

  • How to read the result

    Match the percentage to the mortgage deals you can get. Five to ten percent is common for first buyers; more often opens better rates.

Which deposit percentage should I use?
