Hi all,
This post was inspired by a thoughtful conversation with the beautiful Cherelle — thank you for opening up this discussion and highlighting the importance of smart financial decisions like mortgage overpayments.
In an era of rising living costs and interest rate fluctuations, many homeowners are looking for ways to save money in the long term. One increasingly popular strategy is overpaying on a mortgage — making payments above the required monthly amount. But is it always the right move?
Let’s explore the key benefits, potential drawbacks, and best practices of mortgage overpayments.
✅ The Benefits of Overpaying Your Mortgage
1. Save Thousands in Interest
Every extra pound you pay toward your mortgage reduces the outstanding balance. As a result, you’ll pay less interest over the lifetime of the loan — especially impactful early in the term when interest makes up a larger portion of your monthly payments.
Example: Overpaying just £100/month on a £200,000 mortgage at 5% interest could save you over £20,000 in interest and shave years off your mortgage term.
2. Become Mortgage-Free Sooner
Regular overpayments can significantly reduce the length of your mortgage, helping you gain financial freedom earlier than planned. This gives you more flexibility for retirement planning, investment opportunities, or lifestyle choices.
3. Better Returns Than Saving
If interest rates on savings accounts are lower than your mortgage rate, overpaying your mortgage can offer a better effective return than parking your money in a savings account.
4. Build Equity Faster
Overpayments help you build home equity more quickly. This can be valuable if you want to remortgage, borrow against your home, or simply increase your net worth.
⚠️ Things to Consider Before Overpaying
1. Early Repayment Charges (ERCs)
Some lenders limit how much you can overpay each year without penalty — usually up to 10% of the outstanding balance. Going over this may incur charges, so check your mortgage terms carefully.
2. Emergency Fund First
Before overpaying, ensure you have an emergency savings cushion (typically 3–6 months of expenses). You don’t want to be mortgage-rich but cash-poor in a crisis.
3. Other Debts? Prioritise Higher Interest
If you have unsecured debts like credit cards or loans with higher interest rates, it’s often wiser to pay those off first before overpaying on a mortgage.
4. Losing Liquidity
Overpayments are not easily reversible — unlike savings, you can’t quickly withdraw money paid toward a mortgage if your situation changes.
Tips for Smart Overpayment
-
Set Up a Standing Order: Make regular overpayments automatic — even small monthly amounts add up.
-
Use Lump Sums Wisely: Bonuses, inheritance, or tax rebates can make great one-off overpayments.
-
Check Overpayment Limits: Stay within your lender’s allowance to avoid fees.
-
Request Term Reduction (if allowed): Ask your lender if overpayments will reduce your term, not just your monthly payment.
What Are Capital Receipt Payments?
Capital receipt payments are one-off, non-recurring inflows of funds — such as money received from selling a second property, land, or other long-term assets. These payments are non-taxable in many cases and, if used wisely, can significantly reduce debt burdens.
Instead of letting a capital receipt sit in a low-interest account, applying it as a mortgage overpayment can yield much greater value — by reducing the amount of interest you’ll pay and shortening your loan term.
⚠️ Things to Watch Out For
-
Early Repayment Charges (ERCs): Many lenders allow up to 10% overpayment per year without penalty, but check your terms first.
-
Emergency Fund Comes First: Make sure you have at least 3–6 months’ expenses set aside before committing surplus funds to a mortgage.
-
Other High-Interest Debt: Pay off credit cards or personal loans before overpaying your mortgage if they have higher interest rates.
Final Thoughts
Overpaying your mortgage can be a powerful way to save money, reduce financial stress, and gain freedom sooner — if it aligns with your financial goals and circumstances. Like all major money decisions, it’s worth reviewing your options or speaking to a mortgage adviser to get tailored guidance.
