Method & assumptionsAuthoritative sources

Enter your target house price, required deposit percentage, current savings, monthly saving amount, and savings interest rate to calculate how long it will take to save your deposit. A 10% deposit is the minimum for most lenders, but a 15% or 20% deposit typically unlocks significantly better mortgage rates. Using a Lifetime ISA adds a 25% government bonus on contributions up to £4,000 per year for first-time buyers.

Common mistakes

  • !Mixing up loan amount and property value, which can distort affordability and LTV.
  • !Using a headline rate but forgetting fees, insurance, taxes, or repayment type.
  • !Testing only one term length instead of comparing the payment and total cost together.

What to do next

  • Run a second scenario with a higher rate or shorter term so you can see the downside clearly.
  • Compare the result with an affordability or overpayment calculator before applying.
  • Use the related guides below to understand trade-offs before you request live quotes.
