Buying

True cost of buying calculator

Deposit, stamp duty and fees: the cash you need to get the keys.

  • What it means

    This adds up the cash you need to get the keys: deposit, stamp duty and the usual buying fees.

  • Why it matters

    People often budget for the deposit and forget legal fees, surveys and lender charges. Those still have to be paid.

  • When to use it

    Use it when you are close to offering, or when you want a full cash checklist before you save more.

  • How to read the result

    Focus on the total cash to complete. Replace the fee defaults with real quotes when you have them.
