Quick answer

Usually both, in order. Keep up every minimum payment, build a small emergency fund of around £1,000, then put spare money towards your most expensive debt – typically overdrafts and credit cards. Once high-interest debt is cleared, build three to six months of savings. Mortgage overpayments and investing usually come after that.

You have some spare money each month and two competing voices: "build your savings" and "clear your debts". Both are right – the question is the order.

This guide gives a simple priority ladder, explains why debt interest usually wins, compares the avalanche and snowball methods, and shows when saving should come first and where to get free help.

Should you save or pay off debt first?

Pay all minimums, build a starter emergency fund of about £1,000, keep any employer-matched pension contributions, then put spare money towards your highest-interest debt. Once that is cleared, grow savings to three to six months of essential costs.

A simple priority ladder works for most people:

1.Pay at least the minimum on every debt and keep priority bills (rent or mortgage, council tax, energy) up to date.
2.Build a starter emergency fund of about £1,000 so the next surprise does not go on a card.
3.Keep paying into a workplace pension if your employer adds contributions – stopping usually means losing free money.
4.Put every spare pound – found by trimming your monthly budget – towards the debt with the highest interest rate.
5.When high-interest debt is gone, grow the emergency fund to three to six months of essential costs.
6.Then consider overpaying cheaper debt such as a mortgage, or investing for the long term.

Why does paying off debt usually beat saving?

Debt usually costs more than savings earn. Paying off a credit card at over 20% APR gives a guaranteed, tax-free "return" at that rate, while savings accounts typically pay far less. The exception is a small emergency buffer, which stops you borrowing again.

Because debt interest is usually higher than savings interest. Every pound used to clear a card charging over 20% APR "earns" that rate, guaranteed and tax-free. The same pound in a savings account earning a few per cent earns far less – and savings interest can be taxable above your Personal Savings Allowance.

The exception is the starter emergency fund. Without any cash, one car repair sends you straight back to borrowing, which is why a small buffer comes first.

Typical priority by type of debt
Debt	Typical cost	Priority for extra payments
Payday and high-cost short-term loans	Very high – capped by the FCA at 0.8% a day	Highest
Overdrafts and credit cards	Often 20% APR or more	High
Store cards and some car finance	Varies widely	Medium to high – check the rate
Personal loans	Usually lower than cards	Medium
Mortgages	Usually the lowest rate	Low – after savings are built
Student loans (Plan 2, 4 and 5)	Repaid as a share of income; written off after a set period	Usually lowest

Debt avalanche or snowball: which should you use?

The avalanche method pays the highest-interest debt first and costs the least overall. The snowball method pays the smallest balance first and gives quicker wins. Choose the one you will actually stick with.

Both start with minimum payments on everything. They differ in where the extra money goes.

Debt avalanche

Extra money goes to the highest interest rate first. It costs the least in total interest and clears debt fastest on paper.

Debt snowball

Extra money goes to the smallest balance first. It costs a little more, but quick wins keep many people motivated.

Which to choose

If you will stick with it, the avalanche saves more money. If you have tried and stopped before, the snowball may be the one you finish. Either beats paying only the minimums. The Debt Repayment Calculator shows how long each plan takes.

When is it better to save before paying off debt?

Save first if you have no emergency fund, your income is irregular, your debt is at 0% for a fixed period, your employer matches pension contributions, or you need cash soon and the debt is cheap.

You have no emergency savings at all – build the £1,000 buffer first.
Your income is irregular – hold a larger cash buffer before overpaying.
Your debt is at 0% for a set period – save towards clearing it before the rate rises, and keep that money separate.
Your employer matches pension contributions – keep contributing at least to the match.
You are about to need cash, such as a house deposit, and the debt is cheap.

Worked example: £300 a month to share

A credit card of £2,400 at 24% APR, a personal loan of £5,000 at 9%, and no savings:

Phase 1 – months 1 to 4	£250 a month to savings until the £1,000 buffer is reached; £50 extra on the card
Phase 2	All £300 extra on the credit card (highest rate)
Phase 3	£300 plus the card's old minimum payment onto the loan
Phase 4	Build three to six months of essential costs in savings

Minimum payments continue on both debts throughout. Use the Debt Repayment Calculator to see how long each phase takes with your own balances and rates.

Key takeaways

Minimum payments and priority bills always come first.
A £1,000 starter buffer stops new borrowing.
Clear the highest-interest debt next – usually overdrafts and cards.
Do not give up an employer pension match to repay debt faster.
Free debt advice is available – avoid fee-charging firms.

Frequently asked questions

Should I use my savings to pay off my credit card?

Often yes, if the card charges much more interest than your savings earn – but keep a small emergency fund so you do not end up borrowing again for the next surprise.

Is it better to overpay my mortgage or save?

Build an emergency fund and clear expensive debt first. After that it depends on your mortgage rate, savings rates, any early repayment charges and your other goals. A regulated mortgage adviser can help with the detail.

Does paying off debt improve my credit score?

Lower balances and on-time payments generally help. Closing old accounts can sometimes have the opposite effect, so check before closing a card you have paid off.

Where can I get free debt advice in the UK?

StepChange, National Debtline and Citizens Advice offer free, confidential debt advice. MoneyHelper, backed by the government, has a tool to find free advice near you.

What is the debt avalanche method?

You pay minimums on all debts and put every extra pound towards the debt with the highest interest rate. When it is cleared, its payment rolls onto the next highest. It minimises total interest.

Should I stop pension contributions to pay off debt?

Usually not if your employer adds contributions – stopping means losing that money and tax relief. Get advice if debt payments are unaffordable.

Conclusion

Saving and repaying debt work best in a clear order: minimums, a small buffer, the most expensive debt, then a full emergency fund. Pick the avalanche or snowball method and automate it. The Debt Repayment Calculator shows how long each debt will take, and Spendika tracks the monthly budget that frees up the money.
