Minimum Payment

A minimum payment is the smallest amount a borrower must pay by the due date on a revolving credit account, such as a credit card or a store card, to avoid a late fee and keep the account in good standing. Issuers print it on every statement next to the full balance and the due date. Paying it keeps the account current, but the unpaid remainder keeps accruing interest.

Minimum payments exist because revolving credit has no fixed repayment schedule, unlike an installment plan. They are regulated mainly through disclosure in the US and through rules on persistent debt in the UK. Paying only the minimum is one of the most common ways that card balances become long-lasting and expensive.

Think of a bucket with a small leak at the bottom that keeps adding water: the interest. Each month you must scoop out at least a cupful, the minimum payment, or you get fined. If you scoop out only one cupful, most of it just covers the water that leaked in that month, and the level in the bucket barely drops.

That is why a card paid at the minimum can take many years to clear. Because unpaid interest is added to the balance and then itself charged interest, the effect resembles compound interest working against you. Paying a bit more than the minimum each month lowers the level much faster, because every extra amount goes straight at the balance rather than at the interest.

Each card issuer defines the minimum in its card agreement. Common designs are a percentage of the balance (often 1% to 3%), or a percentage of the balance plus that month's interest and fees, subject to a fixed floor such as $25 or $35, with the whole balance due if it is below the floor. A general form is:

• $\text{MP}$ is the minimum payment for the cycle.
• $F$ is the fixed dollar floor.
• $I$ is the interest, or finance charge, billed for the cycle.
• $\text{Fees}$ are any late or other fees billed for the cycle.
• $p$ is the principal percentage, for example 0.01 for 1%.
• $B$ is the statement balance.

Worked example: a $2,000 balance on a card charging about 2% a month (an APR of 24%) gives interest of $40. With $p = 0.01$ and a $25 floor, the minimum is $\max(25,\; 40 + 0 + 20) = 60$, or $60. Paying the minimum each month, and spending nothing more, takes about 143 months, nearly 12 years, and costs roughly $2,890 in interest. Paying a fixed $78.47 a month instead clears the balance in 36 months for about $825 in interest. Payments above the minimum are where savings come from; in the US, issuers must apply the amount above the minimum to the balance with the highest APR first (12 CFR 1026.53), which matters when a card also holds a balance transfer at a lower rate.

The Credit CARD Act of 2009 and Regulation Z require each US credit card statement to carry a boxed repayment disclosure near the minimum payment due (12 CFR 1026.7(b)(12)). It must show:

• A "Minimum Payment Warning" stating that paying only the minimum will take longer and cost more in interest.
• How long it would take to pay off the current balance making only minimum payments, and the total cost of doing so.
• The monthly payment needed to pay off the balance in 36 months, the total cost at that pace and the saving compared with minimum payments.
• A toll-free number for information on credit counselling.

If the minimum would not even cover the interest, so the balance would never fall, the statement must say so. Paying the minimum on time avoids a late fee and penalty pricing: under Regulation Z an issuer may only raise the rate on an existing balance for delinquency once a minimum payment is more than 60 days late, and must restore the earlier rate after six on-time minimum payments (12 CFR 1026.55). Missing the minimum altogether moves the account towards default and brings a late fee and, at 30 days past due, usually a negative mark on the borrower's credit report and a lower credit score.

In the UK, card minimum payments are typically set to cover interest, fees and charges plus 1% of the balance, so that each payment reduces the debt at least a little. Since 2018 the Financial Conduct Authority's consumer credit rules (CONC 6.7) have required card firms to act on "persistent debt": when a customer has paid more in interest, fees and charges than in repayments of the money borrowed over 18 months, the firm must contact them and encourage faster repayment, with a further reminder at 27 months. If the pattern lasts 36 months, the firm must offer a way to repay the balance over a reasonable period, typically three to four years, and if the customer does not respond the firm will generally have to suspend the card.

Lenders and regulators use the share of customers paying only the minimum as an early sign of financial stress, alongside credit utilisation and missed payments. For borrowers, the minimum is a floor, not a plan. Paying the full statement balance keeps the grace period and avoids interest on new purchases; paying a fixed amount above the minimum, or consolidating into a lower-rate loan, shortens the payoff period. Debt management plans run by credit counselling agencies often negotiate lower rates and a fixed payment in exchange for closing the cards.
