Minimum Payment or Fixed Amount: What Clears Debt Faster

A credit card minimum payment is the lowest amount you must pay each month to keep the account up to date. It is usually calculated as a small percentage of what you owe, plus the interest, fees and charges added that month, so it falls as your balance falls. That is the trap: the smaller the balance gets, the smaller the required payment gets, and the longer the debt lasts¹.

A fixed payment works the other way. You choose an amount above the minimum and it stays the same each month, so more of it goes to the balance as the interest bill shrinks. HSBC's own repayment calculator puts it plainly: by fixing your payment, you repay your balance sooner and pay less interest, which could also help you avoid entering persistent debt³.

The two approaches are not alternatives to clearing your balance in full, which costs no interest at all if you have an interest-free period on purchases. They are the choice you face when you cannot clear it. This page sets out how each one behaves, what the rules require, what the regulator's research found about how people actually repay, and how to set a fixed payment up.

What a minimum payment is and how card providers set it

The minimum payment is the contractual floor on your account. RBS defines it as the lowest amount you must pay in order to keep your credit card payments up to date, and it appears on page 1 of your statement². StepChange's guidance is blunt about what it usually covers: minimum payments usually only cover the interest and charges on a debt¹.

Across the major providers the calculation is described in almost identical terms. RBS, NatWest, Ulster Bank and HSBC all say the minimum is usually 1% of the credit card balance, plus interest and fees and charges, while noting it may differ depending on the product you hold². Experian gives the same floor from the consumer side: your minimum monthly payment must cover at least 1% of the outstanding balance⁹. Some providers may ask you to pay a flat fee instead¹⁰.

Two features matter more than the exact percentage. First, the minimum changes every month with the balance, so it is not a stable figure you can budget around⁸. Second, because it is charged as a percentage of what remains, it reduces as your balance goes down⁸. Which's worked example shows the effect: a minimum repayment of at least 2% on a debt of £500 is £10, but once your debt gets to £400 your minimum repayment falls to £8⁸.

Where the balance is small, a flat floor takes over. Nationwide, for example, describes a minimum of 3% of your statement balance, or £5, whichever is greater, on its Gold and Classic cards¹¹. Experian notes that if your balance is low you may have to pay a fixed amount instead, if this is greater⁹. Student credit cards follow the same shape, with minimums usually ranging between 1% and 3% of what you owe, or a set minimum, whichever is higher depending on the bank⁹.

Fixed monthly payment or minimum payment: how each one clears a balance

The difference between the two is not the amount you pay in month one. It is what happens in month twelve.

A minimum payment is a moving target. It is recalculated each month from the balance, so as the balance falls the required payment falls with it. The debt reduces, but slowly, and the interest charged on the remaining balance keeps taking a share of every payment. StepChange's summary is that making minimum payments could mean you end up paying the debt over a long time¹. Danske Bank states the trade-off directly: only making the minimum repayment will cost you more in interest and take you longer to pay back¹².

A fixed payment holds its level. You tell the provider how much to collect each month, and that figure does not drift down as the balance does. HSBC's calculator describes the benefit as repaying your balance sooner and paying less interest, and notes it could also help you avoid entering persistent debt³. HSBC's general card guidance makes the same point in the negative: if you cannot clear the balance, it still makes sense to pay more than the minimum to reduce the amount of interest you pay¹³.

There is a practical constraint. A fixed direct debit has to be at least the minimum, or the provider collects the minimum instead. HSBC's calculator states that the fixed monthly payment you enter needs to be at least the amount of your minimum payment this month, and that if you owe less than £5 you need to pay the full amount³. First direct applies the same rule to its fixed amount option: it needs to be higher than the minimum shown on your statement, otherwise the minimum is collected¹⁴.

Why paying only the minimum keeps you in debt longer

The arithmetic is simple and unforgiving. If the minimum is roughly 1% of the balance plus the month's interest, then almost all of a minimum payment goes to interest and charges, and only a sliver touches the capital. StepChange identifies the cause of persistent debt as exactly this: the minimum payment is less than the added interest¹⁵.

The regulator has measured how common the pattern is. The FCA's credit card market study found that 5.2%, about 1.6 million people, of active consumers in the last year repeatedly made only minimum payments while incurring interest¹⁶. A further 1.1 million, or 3.7% of credit card holders, had spent at least 12 months making only the minimum repayments¹⁷. The FCA also identified 750,000 cardholders who had been making systematic minimum repayments for at least three consecutive years¹⁸. Its definition of systematic minimum repayment behaviour is consumers who have made nine or more minimum repayments while also incurring interest charges over 12 months¹⁹.

The pattern is sticky. Of consumers making systematic minimum repayments in 2014, 22.6% had been doing so in each of the four preceding years¹⁹. The FCA's market study found an additional 1.6 million people who were repeatedly making minimum payments on their credit card debt¹⁸.

There is a formal threshold that turns this from a habit into a regulated problem. Only making the minimum payments for over 18 months can mean you are in persistent credit card debt⁶. Once a provider identifies that, it has duties towards you, which are set out on our page on persistent credit card debt rules. Thinkmoney describes the common trigger from the customer's side: if you have only been making the minimum payments on your credit card for a while, your lender might get in touch about tackling your persistent debt²⁰.

Minimum repayment rules for newer and older card agreements

The rule that governs most cards in force today dates from 2011. Under CONC 6.7.5R, a firm must set the minimum required repayment under a regulated credit agreement for a credit card or a store card at an amount that repays the interest, fees and charges applied to the account, plus one percentage of the amount outstanding⁴. The rule applies to agreements made on or after 1 April 2011⁴.

That date is the dividing line. The FCA's policy statement is explicit that these rules do not apply to agreements made before 1 April 2011²¹. If your card predates that, your minimum is whatever your original terms say. TSB's product information illustrates the difference between the two regimes on its own book: accounts opened on or after 31 March 2011 have a minimum of 1% of the balance plus interest, while accounts opened before that have a minimum of 2% of the balance or 0.5% plus interest, whichever is the greater⁵.

The rule has been restated consistently since. The FCA's 2014 market study described the requirement as covering interest rates and other fees on the account plus 1% of the amount outstanding for new credit card contracts since April 2011¹⁶. Its interim report and annex repeated the same formulation¹⁷. The FCA's 2018 policy statement summarised the minimum as covering fees, interest and at least one percent of the balance, or £5, whichever is larger²².

There is one documented exception. During the coronavirus payment deferrals, the FCA said its rules in CONC 6.7.5R would not apply if a firm decided to vary its contracts in order to follow the deferral guidance²³. That guidance has since closed, and the legacy is covered on our page on coronavirus payment deferrals. One consequence for anyone who used a holiday: minimum payments rise afterwards, because of the interest added during that time²⁴.

What FCA research found about how people repay credit cards

The FCA has run controlled trials on this exact question, and the results are more interesting than the marketing around repayment tools suggests.

In one experiment, the minimum repayment option was removed from the direct debit setup screen for new customers. About 1 in 5 cards chose a fixed repayment instead of a minimum repayment⁷. In a second trial aimed at existing direct debit customers, targeted disclosure produced a switch from the minimum payment to a fixed payment direct debit equivalent to between 1 and 2 in every 100 cards⁷. The same trial found that if people tried to choose a fixed direct debit amount below £5, they were shown a prompt⁷.

The FCA's Occasional Paper No. 44 reported the outcome of a second experiment targeting credit card users paying their bills via automatic minimum payments. The treatment caused an average reduction in consumers paying only the minimum, and a reduction in credit card debt that was not sustained²⁴. The paper's wider finding, from the FCA's own summary of the research, is that disclosures on time and cost to repay only temporarily reduce credit card debt, and that mistaken beliefs about how repayments amortise explain repeated minimum payment use²⁴.

That last point is the one worth carrying away. People who pay only the minimum often believe the payment is doing more to clear the balance than it is. The FCA's research note on the trials found that removing the minimum repayment option increased repayment choices, but that disclosures had little effect and direct debit changes did not reduce debt⁷.

StepChange has argued that the structure itself is the problem. In its response to the FCA's consultation on creditworthiness, it said the structure of credit card lending, with low minimum repayment requirements, disincentives responsible lending²⁵. In July 2026 it published a report on the credit card regulatory framework calling for reforms on affordability checks, minimum repayments and earlier support for people in persistent debt²⁶. Which? has reported separately that one in five borrowers only made the minimum repayment on their most recent card²⁷.

Setting a fixed payment: by direct debit, in your app or by phone

A fixed payment is set up as a direct debit instruction, and the mechanics are the same across providers even where the wording differs.

First direct sets out the three options on its cards: a direct debit to pay the minimum amount, a fixed amount, or the full amount¹⁴. Experian's guidance is to set up a direct debit to repay your credit card automatically, and notes you can also pay extra online, in your banking app or at a branch²⁸. Macmillan's money guidance frames the same choice for anyone managing repayments alongside treatment: you choose whether to pay off the full amount each month, a set amount or the minimum repayment²⁹.

The fixed amount option carries one rule wherever it appears. If the minimum payment or statement balance due is more than the fixed amount, the minimum payment is taken instead²⁸. HSBC's calculator states the same thing: you need to make sure your fixed amount is more than your current minimum payment, and if it is not, the minimum payment is collected³. First direct's version is that the fixed amount needs to be higher than the minimum amount shown on your statement, otherwise the minimum is collected¹⁴.

Some providers offer a way to pay above the minimum without giving up the minimum calculation. RBS and NatWest run a Minimum Payment Plus direct debit, which collects a voluntary payment on top of the contractual minimum, and can be set up through the mobile app, digital banking or over the phone². The stated purpose is to ensure the balance on your credit card is reducing and to avoid long term debt on your card². The minimum payment used in the provider's own illustration is based on 1% of the credit card balance plus interest, with no additional spending on the card².

What happens if you pay less than the minimum

Paying less than the minimum breaches the terms of your agreement. StepChange's guidance is to make minimum payments to avoid breaching the terms of your agreement³⁰. The consequences are set out across the sources.

Citizens Advice says that if you pay less than the minimum payment, your credit card company might add charges, which will affect the size of your debt and your credit score³¹. Experian lists the same trio of consequences for a late payment: late payment fees, damage to your credit score, and loss of any promotional offers you have⁹. Business Debtline adds that if you start paying less than your original minimum payment, this could be reported to credit reference agencies³².

The credit file effect is worth understanding in full. Experian's guidance is that missed or late payments can negatively affect your credit score, while a minimum payment that covers most of your monthly balance is unlikely to affect it¹⁰. But it also warns that lenders may see only ever making minimum repayments while using a large proportion of your credit card limit as a sign you are struggling, which could negatively impact your credit score⁹. Mental Health and Money Advice states the position firmly: missing payments or making reduced payments to a credit debt, such as a credit card, will affect your credit rating, making it harder to get credit again in the future³³. Defaults stay on your credit record for six years and make it harder to get credit⁹.
