Frequently asked questions
How accurate is this calculator?+
Uses the standard mortgage repayment formula — precise based on your inputs. Actual lender repayments may vary slightly.
Does it include fees and insurance?+
No — this calculates pure capital and interest. Add arrangement fees and insurance separately.
What is LTV?+
Loan-to-Value — the mortgage as a percentage of the property value. Lower LTV typically means lower interest rates.
Repayment vs interest-only?+
Repayment covers interest plus capital — loan fully paid at term end. Interest-only covers only interest — full loan still owed at the end.
Where can I find current mortgage rates?+
See our best remortgage deals guide for current rates.
