How to Pay Off Overdraft Debt in the UK — The Practical Guide

Published 2 April 2026 · Updated 7 April 2026 · About 12 min read · Avalanche vs Snowball

UK arranged overdrafts commonly charge 39.9% EAR — that is often higher than a standard credit card, and much higher than a personal loan. If you are dipping into your overdraft every month and only paying it back as wages arrive, you are renting money at one of the most expensive rates available. Here is how to model it, prioritise it, and get rid of it for good.

Why overdrafts are so expensive: EAR explained

Before 2020, UK banks quoted overdrafts as a daily fee (e.g. 1p per day per £6 borrowed) — making true cost almost impossible to compare. The Financial Conduct Authority changed that in April 2020: banks must now quote a single Equivalent Annual Rate (EAR), so you can compare the cost directly.

EAR works the same way as APR for credit cards: it represents the total annual cost of interest if you kept the same balance for a full year. A 39.9% EAR overdraft on a £1,000 balance costs roughly £399 per year in interest — about £33 per month — just to stay in the red. You are not reducing the principal at all.

Bank (illustrative typical rates)Arranged overdraft EARMonthly cost on £1,000
Major high-street bank A39.9%~£33/month
Major high-street bank B39.9%~£33/month
Major high-street bank C35.0%~£29/month
Some challenger banks15–19%~£13–16/month
Typical credit card APR20–25%~£17–21/month

Rates are illustrative examples based on typical published rates as of 2026. Check your actual account terms for your precise rate.

The real cost of ignoring an overdraft

Many people treat an overdraft as a fact of life — wages clear it at the end of the month, then it fills up again. But the interest charge still runs every day you are in debit, even if the balance goes up and down. Here is what that looks like over time if you never actively pay it down:

£500 overdraft · 39.9% EAR · 3 years
£600

Interest paid while never reducing the balance — more than the original overdraft amount.

£1,500 overdraft · 39.9% EAR · 3 years
£1,797

Three years of staying in the red costs more in interest than clearing it in full today.

£1,500 overdraft · pay £100 extra/mo · avalanche
~18 months

Clear with targeted extra payment. Total interest drops to roughly £260 — saving over £1,500 vs doing nothing.

£1,500 overdraft · 0% money transfer · 24 months
~£45 fee

Move to 0% money transfer card (3% fee), repay over 24 months. Near-zero interest if cleared in time.

Important: These are illustrative figures based on simple interest at stated EAR rates. Your actual costs depend on your bank's exact charging method, whether they compound daily or monthly, and any fees. Always check your account terms.

Should you pay off your overdraft before credit cards?

In the debt avalanche method, you rank every debt by its annual interest rate and direct extra cash at the most expensive one first while paying minimums on everything else. For most UK borrowers, this means:

The calculus changes if you have a 0% credit card with a promotional period still running — in that case the card's effective rate is 0%, so you ignore it until the 0% expires and focus on the overdraft and other high-rate debts. Always enter your current rates, not promotional ones that have already expired.

You can model your overdraft in the free calculator by adding it as a debt with the EAR as the rate and a fixed monthly "payment" that reflects what you can realistically put toward it each month. It will show you exact interest and payoff date alongside your other debts — and the avalanche priority order falls out automatically.

Five steps to clear your overdraft

Overdraft vs other debts: the avalanche priority question

The question "should I pay off my overdraft or my credit card first?" has a clean answer in the debt avalanche framework: whichever has the higher rate gets the extra payment. The rate comparison is usually straightforward:

Debt typeTypical UK rateAvalanche priority
Arranged overdraft (high street)~39.9% EARUsually highest priority
Store card / catalogue credit~34–40% APROften tied with overdraft
Standard credit card~20–29% APRSecond or third
Personal loan~6–15% APRLower priority
0% balance transfer card (active)0%Lowest priority until 0% expires
Arranged overdraft (challenger bank)~15–20% EARMay fall below credit cards

To model your exact situation — overdraft alongside credit cards and loans — enter each as a separate line in the free calculator. The calculator sorts the attack order for both avalanche (highest rate first) and snowball (smallest balance first) and shows you total interest and debt-free date for each method. It does not matter that one is called an "overdraft" and another a "credit card" — the maths only cares about the numbers.

When the overdraft is a symptom, not the problem

If your overdraft refills every month because your income does not cover your essential outgoings, extra payments and 0% transfers will not fix the underlying issue. If that is your situation, the most useful first step is a free, structured conversation with a debt charity. They can help you look at the whole picture — benefits entitlement, priority debts (rent, council tax, utilities), and whether a formal solution such as a debt relief order is more appropriate than an informal repayment plan.
