Before you apply for any credit card, it’s a good idea to get to grips with credit card fees and charges, so you can plan your spending and manage your credit responsibly.  

In this guide, you’ll learn:

• What credit card fees and charges are
• Why interest and fees are charged
• Why the 'representative APR' matters 
• How to stay fee-free
• Why your payment history is a valuable financial asset

There are two main ways you might be charged for using your credit card: interest and fees. 

• Interest: This is a percentage-based cost. It’s calculated daily based on how much you owe, so it can grow over time. If you pay off what you owe in full by the due date, you won't be charged interest.
• Trailing interest: This is the extra daily interest that builds on your balance between your statement date and the date your payment’s received. 
• Fees: These are usually fixed amounts (for example, £12) or a set percentage of a single transaction (like 3% for a balance transfer). They don't increase like interest (though interest can be charged on them), but they show on your balance instantly. Credit card providers manage your account and set the fee amountsopens in a new tab.

Here's the breakdown of some common credit card fees for UK cards:

• Annual fees: A yearly charge for having the card. Capital One cards in the UK have no annual fee, which helps to keep costs low while you build your credit history.

• Late payment fees: This is what you’re charged if your minimum payment doesn't reach your credit card provider by the due date.
• Cash advance/withdrawal fees: This is the charge for using your card at a cash machine/ATM.
• Balance transfer fees: A one-off fee for moving debt from one card to another one.
• Over-limit fees: A charge for spending more than your agreed credit limit.
• Foreign transaction fees: A fee for spending in a currency other than Pounds Sterling.

There’s a difference between interest rates and interest charges, and you’ll often see both when comparing credit cards.

• Credit card interest rate: The percentage (for example, 34.9%) that’s applied to the money you borrow.
• Credit card interest charge: The actual amount of money you’re charged, calculated using the interest rate and your outstanding balance.

Credit cards can have different interest rates depending on how you use them. Understanding these rates can help you compare credit card offers and estimate how much it’ll cost to borrow money. In general, the higher the APR, the more interest you’ll pay on any money you owe. 

Purchase

This is the interest rate applied to any purchasesopens in a new tab made with your credit card that you don't pay off in full by the due date.

Balance transfer

This rate applies to balances you move from one credit card to another. Many balance transfer cards offer a 0% introductory period, but the standard balance transfer APR will apply once that period ends.

Cash withdrawal

Cash withdrawals (also known as cash advances) usually have a higher interest rate than purchases or balance transfers, and interest is typically charged from the day you withdraw the cash – even if you pay your statement in full.

The terms "interest rate" and "APR" (Annual Percentage Rate) are often used interchangeably, and for many credit cards, they do mean the same thing. However, the interest rate is the base percentage charged on the money you borrow each year. The APR gives you a broader pictureopens in a new tab. It includes the interest rate plus any standard account fees you have to pay.

Capital One UK cardsopens in a new tab have no annual fee. This means your interest rate and APR will usually be the same. For cards that charge a fee to use them, the APR will be higher than the interest rate to show you the 'true' total cost.

Other charges, like late payment fees or balance transfer fees, are not included in a card’s APR.

Credit card interest isn’t a flat monthly fee - instead, it’s calculated every day. Most providers use the Daily Periodic Rate (DPR), which is the interest rate applied to your daily balance. It tells you how much interest will accumulate daily, and it means that the interest you pay compounds. 

Here's how you can calculate exactly what your balance is costing you:

1. Find your daily rate. Take your APR (for example, 34.9%) and divide it by 365 (days in a year).
2. Once you have the APR – in this example, 34.9 is divided using the 365 calculation to leave 0.095% as the daily periodic rate.
3. Apply to your balance. If you have an outstanding balance of £1,000, your daily interest charge is roughly 95p. This will compound; so if it’s not paid off, you’ll end up paying interest on your interest.

While 95p might sound small, over a 30-day month, that’s £28.50 added to your debt. By making even small repayments mid-month, you reduce the average daily balance, which in turn reduces the total interest charge at the end of the month.

If you pay off your entire statement balance every month by the due date, you usually won't be charged any interest on your purchases. Of course, you should only do this if you can afford to and it’s not at the expense of any other financial priorities.

You could also consider a balance transfer cardopens in a new tab to reduce interest on existing cards while you pay off what you owe. For instance, if you have £2,000 on a card at 25% APR, then you're paying roughly £40 a month just in interest. By moving it to a 0% card, that £40 can go toward paying off the actual debt instead. The transfer will cost a fee, and make sure you’re aware of how long the 0% period lasts, plus what the rate is after it ends.

Credit card fees can be avoidable. These tips could help you keep to just paying your balance:

• Pay off the balance in full and on time: As with interest fees, keeping on top of repayments prevents late fees. If you can't afford to pay off in full, pay as much as you can afford and always make the minimum repayment.
• Set up a Direct Debit: Setting up a Direct Debit for at least the minimum payment can help make sure you don’t miss a payment deadline, even if you’re busy or on holiday. 
• Time your payments with payday: If you get paid on the 25th, consider setting your card payment for the 26th. This helps make sure the money is in your account. 
• Monitor your credit limit: Knowing how close you are to your credit limit could prevent you from accidentally going over your limit and triggering a fee.
• Get a travel-specific card: If you travel often, look for a card that offers 0% fees on foreign spending. These often won’t charge you for ATM withdrawals abroad, either. Just make sure to check the specific terms of your card before travelling.

Check your transactions. Before you get in touch with your card provider, check if you’ve recently bought something like a lottery ticket, gift card or foreign currency. Most UK providers treat these as 'cash advances'. Even though you bought them at a checkout, they trigger the same fees and immediate interest as taking cash out of an ATM.

If you do spot a charge you don't recognise, contact your provider as soon as possible Most have a dispute or chatopens in a new tab function. If it’s a genuine error, like being charged a late fee when your Direct Debit was active, they can usually reverse it and any associated interest immediately.

Remember that under UK rules, if a fee was applied incorrectly due to a bank error, you're entitled to a full refund of the fee plus any interest added.

Being charged a fee doesn't always directly hurt your credit score, but the reason why you were charged often does.

In the UK, credit reference agencies like Experianopens in a new tab, Equifaxopens in a new tab and TransUnionopens in a new tab don't see a specific line on your report for a £12 late fee. Instead, they’d see that you missed a payment, and your payment history is often the most important factor lenders look at. 

Here's why staying on top of your due date matters:

When you miss a payment, a 'marker' is placed on your credit file. This stays visible to other lenders (like banks, mobile phone providers and even landlords) for six years, even after you’ve paid off the balance. 

To a lender, a late payment suggests you might be struggling to manage your commitments. This can lead to a lower credit score, meaning you might be offered lower credit limits or higher interest rates in the future.

If you're planning to buy a home, many high-street mortgage lenders prefer a clean record. A recent late payment could result in your application being declined or a lender offering much higher interest rates.

The impact of a late payment fades over time. A mistake made five years ago matters much less to a lender than one made last month. By getting back into a routine of on-time payments, you can steadily rebuild your score.

When you see a credit card advert, the APR is listed as "representative". Under FCA (Financial Conduct Authority) regulations, the lender must offer that specific rate to 51% of successful applicants. The other 49% may be offered a higher rate based on their credit history.

At Capital One, we believe in being upfront. Instead of guessing, we recommend using an eligibility checker like QuickCheckopens in a new tab. This tool performs a soft search, which doesn't affect your credit score, to show you exactly which of our cards you're eligible for and the actual APR you will receive before you officially apply. You can find similar tools with other providers. 

This means you won't have to worry about application rejection, which can leave a mark on your credit file. Importantly, you'll also know how much APR you could be charged if you don't pay your credit card balance in full.

Here's a checklist that can help you stay on top of fees and charges: 

• Before applying, use a soft-search tool like QuickCheckopens in a new tab to see if you're eligible for a card with no annual fee.
• When you get your card, set up a Direct Debit to take your payments. 
• If you can afford to, pay off your balance in full each month. 
• If you're travelling, check your card's foreign transaction rate before heading to the airport.
• Monitor your balance and limit regularly (the Capital One appopens in a new tab makes this simple).
