Here's How the Minimum Payment Floor on Your Credit Card Could Cost You Hundreds of Pounds
Have you ever looked at how the minimum monthly payment on your credit card is calculated? Most people haven’t. In the January 2026 economy, understanding your minimum payment 'floor' is a critical survival skill. With the average UK credit card interest rate (APR) hitting 24.66%—the highest in over 30 years—and the average household credit card balance reaching £2,601, the 'minimum payment trap' is no longer just a slow way to pay; it is a multi-thousand-pound risk that can keep families in debt for decades.
What is the Minimum Monthly Payment Calculated?
Your minimum payment is largely dictated by your interest rate, as well as your outstanding balance and any default charges.
While the national credit card rate average sits at 24.66%, those with poor credit now typically face an APR of 36.2%. For certain credit-builder products, rates can even climb to a staggering 59.9% variable. These record-high benchmarks mean that the 'interest' portion of your minimum payment is now significantly larger, leaving less of your money to actually reduce your debt.
How do Credit Cards Calculate Minimum Payment?
Each credit card company has their own rules for calculating your minimum monthly payment, but typically a minimum monthly payment is calculated as the highest of:
- £5 (or the full outstanding balance if it's less than £5)—this is called the "floor"
- 2.5% of the balance
- 1% of the balance plus interest and default charges
What is the Floor of the Minimum Monthly Payment?
The minimum monthly payment "floor" is a small amount that your minimum monthly payment will never fall below. Most credit cards impose a floor of only £5 but some credit card providers (e.g., Tesco Bank, Amex and Vanquis) have a higher floor between £10 and £25.
At first glance, a smaller floor may seem better—but it’s not. The smaller the floor, the longer it will take to pay back credit card debt and the more interest you will pay along the way. A higher floor helps you pay back debt sooner and pay less in interest charges.
Because interest compounds so much faster at these rates, a higher floor prevents thousands more in interest from accruing compared to a lower floor. With 10% of UK adults currently having no cash savings, these interest savings aren't just a 'bonus'[symbol:mm-dash]they are a vital pillar of financial resilience in an expensive market.
The following chart compares the total interest paid over time for a £5 floor and a £25 floor, on a £1,000 initial balance where only the minimum payment is made each month. In this case, the higher floor saves the card holder a whopping £770 in interest charges over the life of the debt—that's nearly as much as the original balance! And at a higher APR, the results would be even more staggering.
When Does the Floor Kick In?
If you don't add to credit card balances, your minimum payment should decline over time as you reduce the amount owed. Why? The minimum payment is (in part) calculated as a percentage of the balance. So as the balance drops so do the minimum payments—until the "floor" is reached.
For most credit cards charging 19.9% APR, a £25 floor would kick in for balances below £1,000 or so (if your minimum payment is calculated using 1% of the amount owed, not a higher amount). This means that each month the minimum payment would be a fixed £25—it would not drop below £25 as you work to pay down the balance from £1,000 to zero.
A card with a lower floor of £5 would take much longer to pay off, because the minimum payment would continue to decline until the balance falls to around £200, at which point the £5 floor kicks in.
| Floor | Floor Kicks in for Balances Below… | Time to Pay Debt | Total Interest Charges |
|---|---|---|---|
| £5 | £200 | 18 years 6 months | £1,390 |
| £25 | £1,000 | 5 years 4 months | £599 |
The following chart shows how the time to become debt free is drastically reduced if the minimum payment floor is higher, for those who only pay the minimum amount due each month.
With the 2026 national average now at 24.66% APR, the 'floor' triggers much sooner. At this rate, a £25 floor will generally kick in for balances below approximately £820. This is because at a higher APR, the interest and percentage-based portion of your payment stays above £25 for longer.
Should You Only Pay the Minimum Each Month?
While it's critical to pay the minimum amount each month (to avoid default charges, being reported to credit agencies, etc.), it's actually really important to pay MORE than the minimum each and every month. The more you pay, the better. Paying as much as you can over the minimum each month will:
- Reduce the total amount of interest you pay over the life of the debt
- Reduce the time to become debt free.
Generally speaking, credit cards are an expensive form of debt and balances should be reduced as soon as possible, which you can help along by paying more than the minimum each month.
How to Find the Minimum Payment Floor
The minimum payment floor can be found in the Summary Box for a credit card, in the section labelled, "Minimum Payment." If you're someone who might pay only the minimum amount each month, you may want to consider a card with a £25 minimum payment floor to save money in interest charges in the long run. If you want to find a minimum payment for a card, you can oftentimes find it by Googling the brand and product line of the card, plus "summary box". Most credit card companies provide easy access to the summary box (as they should, in our opinion).
The following table shows the minimum monthly payment floor for a list of UK credit cards. This alphabetical list is not exhaustive, is subject to change and may vary from card to card; this list is only meant to illustrate the range of floors available in the UK market.
| Card Card Provider | Minimum Monthly Payment Floor |
|---|---|
| American Express | £25 |
| Aqua | £5 |
| Asda | £5 |
| Barclays | £5 |
| Halifax | £5 |
| HSBC | £5 |
| Lloyds | £5 |
| Marbles | £5 |
| MBNA | £25 |
| Partnership Card | £5 |
| RBS | £5 |
| Tesco | £25 |
| Vanquis | £10 |
| Virgin Money | £25 |
For many cards the payment may be a formula, e.g. for the AMEX Platinum Cashback, it's the sum of all interest, default fees, and 1/12th of the annual fee, plus 2% of the remaining balance

Escaping the Debt Spiral
As of 2026, 24% of UK adults are defined as having 'low financial resilience', a precarious position given that average non-mortgage debt has climbed to £18,392. In this climate, simply paying the minimum is a recipe for a debt spiral. Actively aiming to pay even £10 or £20 above your 'floor' each month is one of the most effective ways for modern households to reclaim their financial freedom.
