Home Improvement Loan Calculator

Compare the monthly cost of a personal loan, secured loan and further advance for financing home improvements.

This tool lines up the three common ways homeowners finance a big improvement project so you can see the monthly and total cost of each side by side, rather than being sold whichever product the person in front of you happens to offer. Its main limitation is that the further advance rate shown is illustrative — actual further advance pricing depends heavily on your loan-to-value, your existing lender's criteria, and whether they'll offer one at all, so the cheapest number on paper here isn't automatically available to you.

These are illustrative rates, not personalised quotes — actual rates depend on your credit profile, the lender, and (for further advances) your loan-to-value and lender criteria. Lender fees may also apply and are not included here. This calculator is illustrative only and does not constitute financial advice. Always confirm figures with a lender, broker or HMRC before making a decision.
