Monthly Payment Breakdown for a £125,000 Remortgage
For a £125,000 repayment mortgage over a 25-year term, here are the approximate monthly costs at rates relevant to the current UK market.
At a 5-year fixed rate of 4.3%, the monthly repayment is approximately £681. At a 2-year fixed rate of 4.6%, the monthly cost is around £702. On a standard variable rate of 7.5%, you would pay approximately £924 per month.
Switching from the SVR to the 5-year fix produces a monthly saving of roughly £243, an annual saving of approximately £2,917, and a total saving of around £14,584 over five years. The 2-year fix versus SVR comparison yields a monthly saving of about £222 and an annual saving of roughly £2,662.
Borrowers on a shorter remaining term — for example 15 years rather than 25 — will see higher monthly payments because more capital is being repaid in each instalment, but will pay significantly less interest overall. On a 15-year term at 4.3%, a £125,000 mortgage costs around £929 per month compared to £681 over 25 years, but total interest paid is substantially lower. Always model different term lengths when remortgaging if you have the income to support a shorter term.
LTV Ratios and Rate Tiers for a £125,000 Loan
Your LTV is calculated by dividing your outstanding loan by the current value of your property. On a £125,000 loan, the LTV you sit in will depend heavily on your property's current market value, which may have changed significantly since you last remortgaged.
A £125,000 loan on a property worth £156,250 gives an LTV of exactly 80%, placing you in the 80% rate tier. On a property worth £166,667 you would be at 75% LTV, and at a property value of £208,333 or above you would drop below 60% LTV and access the most competitive rates on the market. In much of the UK, a property purchased five or ten years ago at this loan level will have appreciated enough to put the borrower comfortably below 75% LTV, and often below 60%.
Moving from the 75% LTV tier to the 60% LTV tier typically unlocks a rate reduction of 0.15 to 0.35 percentage points depending on the lender and fix length. On £125,000 over 25 years, a 0.25% rate reduction is worth roughly £16 per month — or around £960 over five years. It is always worth checking whether you sit just above a rate threshold and, if so, whether a small lump-sum overpayment could push you into the lower band.
Borrowers at 85% or 90% LTV on a £125,000 loan have a property worth £147,000 to £139,000 respectively. At these levels you will face a narrower product range and higher rates, but remortgaging is still very much achievable through both mainstream and specialist lenders.
