You send in more than the minimum. Where does the extra money go? On a card with more than one balance, the answer is not random. A federal rule sets the order. Let's walk through it one step at a time, with plain definitions along the way.
The basic rule for paying above the minimum
The rule sits in Regulation Z, section 1026.53, and it covers open-end consumer credit card accounts that are not secured by your home. You can read the text on the Consumer Financial Protection Bureau (CFPB) site. It governs one thing: the amount you pay above the required minimum. The minimum itself is handled separately.
Here is the order. The issuer must apply the extra amount first to the balance with the highest annual percentage rate, or APR. That is the yearly price of borrowing. If money is left over, it moves to the balance with the next-highest APR, and so on down the list. The same regulation text spells this out.
Why does it matter? A dollar sent to a high-rate balance stops more interest than a dollar sent to a low-rate one. The rule points your extra dollars at the costliest debt first.
Why one card can have several balances and APRs
One card is often several balances in a trench coat. Many issuers charge one APR for purchases and other rates for cash advances, checks written on the card, or other transaction types. Each category can carry its own balance and its own rate.
The OCC's consumer help site gives a simple example. If the cash advance balance has the highest APR, your extra payment goes to the cash advance balance first, even if you mostly use the card for groceries. You can see that explained on HelpWithMyBank.gov. That guidance is for national banks and federal savings associations, and it is not legal advice.
Your statement should list each balance category with its APR and the amount owed. Find that section first. It tells you which balance is first in line. If your statement lumps everything together, ask the issuer why. The CFPB's explanation of card interest describes the disclosure you should expect.
How daily interest and the grace period interact
Many issuers figure interest every day. They take your average daily balance and multiply it by the daily periodic rate, which is simply the APR split into a daily slice. Each day a balance sits unpaid adds a little more interest. That is why paying sooner usually costs less.
Many cards also offer a grace period. Pay the full statement balance by the due date, and you can often avoid interest on new purchases. Two catches apply. The grace period usually covers new purchases only. And it typically applies only if you were not already carrying a balance from the prior cycle.
So carrying a balance can cost you the grace period. Then new purchases may start gathering interest right away. A good question for your issuer: does my card have a grace period, and what does it cover?
Deferred interest plans and the end-of-period rule
Deferred interest plans are often offered at checkout for bigger buys like furniture or electronics. You avoid interest if you pay the purchase in full by a set date. If you do not, the interest that was set aside can be charged back to you.
The federal rule adds a timing twist. In the last two billing cycles before the deferred interest period ends, the issuer must apply your extra payment first to the deferred interest balance. Only then does the leftover follow the usual highest-APR order. The point is to help you clear that balance before the window closes.
Outside those last two cycles, the issuer may, at its option, apply extra payments to the deferred balance the way you ask. May means it can say no. Ask directly, and read the written account terms.
- Find the end date of each deferred interest plan on your statement or terms.
- Mark the last two billing cycles before that date.
- Check the next statement to see where your payment landed.
Secured balances and requests for specific allocation
Some card accounts carry a secured balance. For that balance, the issuer may, at its option, apply an extra payment to it if you request that. Again, the choice is the issuer's. Ask, then confirm the result on your next statement.
Home-secured credit lines, such as a home equity line, are outside this rule. They follow different rules, so the order above may not apply to them.
If you cannot tell how a payment was applied, start with the statement's breakdown by balance category. Then call the issuer and ask a plain question. If the answer does not match the rules, the CFPB and the Federal Trade Commission both accept consumer questions and complaints.
What to check on your statement
Keep this short list nearby when the next statement arrives.
- Which balance has the highest APR?
- Is there a deferred interest plan, and when does it end?
- Does my card have a grace period, and is it for purchases only?
- Can I request a specific allocation, and will the issuer honor it?
One more rule is worth knowing. Under the CARD Act, issuers must give written notice at least 45 days before an APR increase or other significant change takes effect, as summarized in this overview of the Regulation Z card rules. A rate change can reshuffle which balance is the highest.
