Making extra mortgage payments could help you become mortgage-free sooner. But with savings accounts offering interest too, is paying more towards your home loan always the smartest move? Here’s why speaking to your mortgage broker before making a decision could be worthwhile.
For many homeowners, becoming mortgage-free is one of their biggest financial ambitions.
The prospect of paying off your mortgage years ahead of schedule, saving interest and freeing up money each month is certainly appealing.
And if you have built up some savings or find yourself with a little extra money left over at the end of the month, putting it towards your mortgage might seem like the obvious choice.
But is it always the right one?
Depending on your mortgage interest rate, the returns available on savings and your wider financial circumstances, keeping your money in a savings account could sometimes leave you better off.
Before making additional mortgage payments, it is worth understanding how the numbers stack up and what the decision could mean for your financial flexibility.
This is where speaking to your mortgage broker can make a difference, helping you understand your current mortgage, the options available and the potential implications of overpaying.
Could overpaying your mortgage save you thousands?
When you make your monthly mortgage payment, part of that money generally goes towards interest, while the rest reduces the outstanding balance if you have a repayment mortgage.
Making an additional payment reduces what you owe, which can help lower the amount of interest charged in the future1.
Over time, regular overpayments could help you repay your mortgage sooner and reduce the overall cost of borrowing1.
For example, a homeowner with a substantial mortgage balance and several years remaining on their deal might benefit from making relatively modest additional payments each month.
But the amount saved will depend on factors including their interest rate, outstanding mortgage balance, remaining term and how the lender applies overpayments.
Some lenders allow borrowers to use overpayments to reduce their mortgage term, while others may recalculate their monthly repayments.
Understanding these differences matters, particularly if your goal is to become mortgage-free sooner.
A mortgage broker can help you review your current mortgage arrangements and understand how making extra payments could affect your longer-term plans.
But could your savings earn more elsewhere?
It might sound surprising, but paying off your mortgage faster is not always the most financially advantageous use of spare cash.
Imagine you have a fixed-rate mortgage charging 2 per cent interest, but can earn 4 per cent on your savings.
In this simplified example, keeping money in savings could provide a greater financial return than the mortgage interest you would avoid by overpaying1.
However, the comparison becomes less straightforward when you consider the tax that may be payable on savings interest, whether the savings rate is fixed or variable, and when your existing mortgage deal expires2.
If you are paying a higher mortgage interest rate than you can earn on savings after tax, overpaying could potentially be more attractive2.
There is also another important consideration: access to your money.
Savings held in an accessible account can usually be withdrawn if unexpected expenses arise.
Money paid towards your mortgage, however, may not be readily available again without arranging further borrowing.
That financial flexibility can be particularly valuable when managing household costs.
A mortgage broker can help you understand the mortgage implications of overpaying, although advice on savings products and tax may require a suitably qualified specialist.
Watch out for the charges that could eat into your savings
Before making a large mortgage overpayment, there is an important detail worth checking.
Some mortgage lenders charge borrowers for repaying more than a specified amount during their mortgage deal.
These are known as early repayment charges.
Many lenders allow penalty-free overpayments of up to 10 per cent of the outstanding mortgage balance each year, but allowances vary between products and providers1.
Some lenders calculate the allowance differently, and certain mortgages may offer greater flexibility.
Exceeding your permitted overpayment amount could result in charges that reduce or even outweigh the financial benefit you hoped to achieve.
That is why checking the terms of your mortgage is essential.
Your mortgage broker can help you understand the overpayment conditions attached to your existing deal and whether any restrictions could affect your plans.
Could overpaying unlock a better mortgage deal?
There is another potential benefit to reducing your mortgage balance that homeowners may not have considered.
It could improve your loan-to-value ratio, commonly known as LTV.
This is the percentage of your property’s value that you still owe on your mortgage3.
For example, if your home is worth £300,000 and you owe £180,000, your loan-to-value ratio is 60 per cent.
Lenders often offer different mortgage products depending on the borrower’s loan-to-value ratio3.
By reducing your outstanding balance, you may move into a lower LTV bracket, which could potentially give you access to different rates when your current deal ends3.
However, this is not guaranteed. Your property’s valuation, lender criteria and the mortgage products available at the time will all influence your options.
A mortgage broker can assess your current LTV position and help you understand whether reducing your mortgage balance might make a meaningful difference when you next review your deal.
Importantly, making an additional payment does not automatically mean you will qualify for a cheaper mortgage.
Don’t forget the importance of a financial safety net
While becoming mortgage-free sooner is an attractive goal, using all your spare money to reduce your mortgage balance could leave you financially exposed.
Unexpected household expenses can arise at any time.
A boiler breakdown, expensive car repair or sudden change in employment could quickly put pressure on your finances.
Having accessible savings can provide an important buffer against these costs.
MoneyHelper suggests having at least three months’ worth of essential expenses set aside before considering early mortgage repayment1.
And if you have other borrowing with higher interest rates, such as credit cards or personal loans, addressing those debts may sometimes be a greater financial priority1.
The key is finding a balance between reducing what you owe and maintaining sufficient financial flexibility.
For homeowners with offset or flexible mortgages, there may also be ways to use savings to reduce mortgage interest while retaining access to some of their money, subject to the lender’s terms1.
Your mortgage broker can explain whether these features are available and how they work.
Five questions to ask before making an overpayment
Before transferring extra money to your mortgage lender, consider the following:
- How much interest could I actually save? Ask your mortgage broker to help you understand the potential impact of overpayments on your balance, repayments and mortgage term.
- Are there any early repayment charges? Check how much you can overpay without penalties and how your lender calculates its allowance.
- Would keeping the money in savings be more beneficial? Compare your mortgage interest rate with the return on savings after any applicable tax.
- Do I have enough money set aside for emergencies? Consider whether you could manage unexpected household expenses without relying on additional borrowing.
- Could reducing my mortgage balance improve my future options? Your broker can help you understand your loan-to-value position and how it might affect your next mortgage review.
There is no single answer that will suit every homeowner.
For some borrowers, making extra mortgage payments could provide worthwhile long-term benefits. For others, maintaining accessible savings or addressing other financial priorities may make more sense.
Before you overpay, speak to your mortgage broker
Once your mortgage is in place, it can be easy to simply make the required repayments each month without giving it much further thought.
But understanding how your mortgage works, particularly its overpayment allowances, restrictions and flexibility, could help you make better-informed financial decisions.
Your mortgage broker can help you review your current arrangements, explain the potential effects of additional repayments and consider how reducing your balance could influence your future mortgage options.
They can also help you understand whether your mortgage offers features that may be useful if your financial circumstances change.
The aim is not simply to pay off your mortgage as quickly as possible, but to make sure the decisions you take are appropriate for your circumstances and longer-term plans.
Your home/property may be repossessed if you do not keep up repayments on a mortgage or other debt secured on it.
There may be a fee for mortgage advice. The precise amount of the fee will depend on your circumstances.
Think carefully before securing other debts against your home/property.
