Interest rate

What is an interest rate and why does it matter?

Imagine walking into a furniture shop and finding the perfect sofa to survive your children’s sticky fingers. The price tag says £1,000, but the salesperson gives you an option. You can pay the full amount upfront or £90 monthly over a year. You will be charged £1,080 if you choose the monthly payment option, paying an extra £80 in interest.

Interest rates are all around us, whether we realise it or not. They influence how much we pay for loans, how much we earn on our savings, and even how businesses set their prices. At its core, an interest rate is the price of using someone else’s money. Understanding how they work is essential for anyone who wants to make better financial decisions.

How do interest rates work?

When someone lends money, they take the risk that the borrower might not repay it. The lender charges interest to compensate for this risk and for the time the borrower is without their money. The higher the risk, the higher the interest rate.

Sometimes, lenders ask for collateral to secure the loan. Collateral is something valuable, such as a car or a house, which the lender can claim if the borrower cannot repay the loan. Loans without collateral, like credit cards, are riskier for the lender and tend to have higher interest rates.

Who decides interest rates?

In the UK, the Bank of England sets the base rate, which is the financial world’s equivalent of the starting bid at an auction. Banks use this rate to decide how much they charge borrowers and how much they pay savers.

Although these decisions may seem far removed from everyday life, they directly impact households. A rise in the base rate could mean higher mortgage payments or loan costs. A lower base rate might make borrowing cheaper, but it could also reduce how much savers earn on their accounts.

Why does this matter to you?

Interest rates affect many parts of personal finance. If you have a mortgage with a variable rate, changes in the Bank of England base rate could increase or decrease your monthly repayments. If you are saving for a future expense, such as a wedding or a home, a higher interest rate on your savings account can help your money grow more quickly.

Lenders also use interest rates to measure the risk of lending to you. A high interest rate might mean the lender sees you as a higher-risk borrower. Improving your financial habits, such as paying bills on time and reducing debt, can help you qualify for lower rates in the future.

Borrowing and managing interest rates

Borrowing money can be helpful when done responsibly. Before taking on a loan, consider whether it is necessary and how it fits into your long-term financial goals. Borrowing for a home or education can be worthwhile, but having a clear and realistic repayment plan is important.

Consider how interest will affect the total cost and ensure your repayments are manageable. If you choose a loan with a variable rate, remember that repayments could rise if interest rates go up. Fixed-rate loans, while sometimes slightly more expensive up front, offer stability.

Leveraging your savings 

When you save money in a bank or investment account, the bank uses your funds to lend to others or invest, and they pay you interest as a reward for letting them use your money. A higher interest rate means your savings grow faster, helping you reach financial goals sooner.

Regularly check that you are getting the best rate from a reliable institution. Even a small difference can significantly impact, especially when saving for long-term goals like a home, a wedding, or future education. Staying informed ensures your money works as hard as you do.

Empowering Your Financial Future

Interest rates are an essential part of how we borrow and save, influencing the cost of loans and the growth of savings. Understanding their role gives you the tools to make informed decisions that align with your goals.

When borrowing, always evaluate whether the loan is necessary, consider the impact of interest on the total cost, and ensure your repayments are manageable. For savers, regularly review your accounts to find the best interest rates and maximise your money’s growth.

By understanding how interest rates work and how they are determined, you can approach your finances with confidence.
