Why You Should Use Your Savings to Pay Off Debt

If you have both savings and debt, you are very likely paying more in interest on your debt than you are earning on your savings. Using your savings to clear that debt will almost always leave you better off. The maths is straightforward: debt interest rates are typically far higher than savings rates, so holding both at the same time costs you money.

Why holding savings alongside debt usually costs you money

Banks and building societies profit by borrowing money from savers at a low interest rate and lending it back out at a higher rate. When you hold savings and debt with the same bank, you are effectively funding your own loan. The bank pays you, say, 4 per cent on your savings and charges you 25 per cent on your credit card balance. The difference is the bank's profit at your expense.

According to the Bank of England, the average credit card interest rate in the UK sits above 20 per cent. The best savings rates available in 2026 remain well below this. Closing this gap by using savings to pay off debt is one of the most reliable ways to improve your financial position.

When you should NOT use savings to clear debt

There are a few situations where using savings to pay off debt is not the right move.

Some loans include early repayment charges. If your personal loan agreement penalises you for settling early, the charge may outweigh the interest saving. Read your loan agreement carefully or call your lender to find out what the penalty would be.

Interest-free debt is another exception. If you have a balance on a 0 per cent credit card still within its promotional period, there is no interest being charged, so clearing it early gains you nothing immediately. Keep the minimum payments going and use your savings elsewhere.

Student loans in England do not work like commercial debt. Repayments are income-contingent and the loan is written off after a set period. The Money Saving Expert Student Finance Calculator can help you work out whether overpaying your student loan makes sense in your specific situation.

Which debts should you clear first?

Clear your most expensive debts first. Sort your debts by interest rate, highest to lowest, and target the top of the list. This approach is sometimes called the avalanche method and it minimises the total interest you pay.

Once the highest-rate debt is cleared, move on to the next. Continue until all your non-beneficial debts are gone.

Should you use savings to overpay your mortgage?

Yes, in most cases. Many people forget that a mortgage is a debt and overlook it when prioritising repayments. Overpaying your mortgage reduces the outstanding balance, which means less interest accrues over the remaining term.

Most lenders allow overpayments of up to 10 per cent of the outstanding balance per year without penalty. Check your mortgage terms before making an overpayment. If you are on a tracker or variable rate, overpaying is usually straightforward. On a fixed rate, confirm the annual overpayment allowance first.

Overpaying is particularly worth considering if your loan-to-value (LTV) ratio is close to a lower tier, such as 85 per cent or 75 per cent. Crossing that threshold can open up cheaper remortgage rates when your current deal expires.

What about keeping an emergency fund?

You do not need to choose between being entirely debt-free and having no cash whatsoever. A sensible approach is to keep a small emergency buffer, typically one to three months of essential living costs, in an easy-access account. Use the rest of your savings to pay down debt.

If you have very little in savings and a large amount of high-interest debt, organisations such as StepChange or Citizens Advice offer free, impartial debt advice. A debt adviser can help you work out the most practical repayment strategy for your situation.

Frequently Asked Questions

Is it better to save or pay off debt?

In almost every case where the debt carries a higher interest rate than the savings rate, paying off the debt first is the better financial decision. You effectively earn the debt's interest rate on your "investment" in repayment, which is almost always higher than any savings account can offer.

Should I clear my credit card with savings?

Yes, if you can afford to do so without leaving yourself with no emergency buffer. Credit cards in the UK typically charge between 20 and 30 per cent APR. No savings account pays anything close to that, so clearing the balance saves you money immediately.

Can I use savings to pay off a loan early?

You can, but check your loan agreement first. Many personal loans include early repayment charges, often equivalent to one to two months' interest. If the charge is smaller than the interest you would save by clearing the debt, it is still worth doing.

What if I need my savings for something specific?

If you are saving for a known upcoming cost, such as a tax bill, a deposit, or essential home repairs, ring-fence that money and use only the remainder to pay down debt. Do not use money you know you will need within the next few months.

Does paying off debt improve my credit score?

Clearing debt typically improves your credit score over time by reducing your overall debt burden and improving your credit utilisation ratio. However, closing an old credit account after paying it off can sometimes temporarily lower your score by reducing your available credit. Seek advice from a credit reference agency such as Experian, Equifax or TransUnion if you are unsure of the impact.
