The Fed just raised rates. Which of your debts will cost more?
The Fed made its first rate hike since 2023 on September 16. See which debts go up, which stay locked, and what the hike costs you each month.

Most people assume a credit card comes with a single interest rate. However, if you look at the fine print of a cardholder agreement, you will likely see four or five different rates listed for the same account. A credit card can have multiple APRs because card issuers charge different rates based on the type of transaction you make. MoneyAtlas makes it easier to compare these rates across hundreds of different cards, and you can start with our best credit card comparison to see which options offer stronger terms for your spending habits. Understanding why these rates differ is essential for avoiding high interest costs and managing debt effectively. This article explains the mechanics behind multiple APRs, how they are calculated, and how to compare options when looking for a new card.
Credit card issuers view different types of transactions as having different levels of risk or cost. For example, a standard purchase is a routine transaction, but a cash withdrawal from an ATM using a credit card is often seen as a sign of financial distress. Because of this perceived risk, the bank charges a higher rate for the cash.
Annual Percentage Rate, or APR, represents the yearly cost of borrowing money on your card. This figure includes the interest rate and certain fees. When a card has multiple APRs, it means the bank is segmenting your balance into different "buckets." One bucket might be for your morning coffee and groceries, while another bucket is for a balance you moved from an old card. Each bucket accrues interest at its own specific rate. If you want a deeper breakdown of how APR works, our guide to what APR means on a credit card is a helpful next step.
Most modern credit cards include at least three or four of the following APR types. It is important to check the Schumer Box, which is the standardized table of rates and fees, to see the specific numbers for any card.
This is the most common rate. It applies to the standard things you buy, such as gas, clothing, or dining out. If you pay your statement balance in full every month, you usually will not owe any interest on these purchases due to the grace period. Most grace periods last at least 21 days from the end of a billing cycle.
If you use your credit card to get cash from an ATM or to buy a money order, you are taking a cash advance. These transactions almost always carry a significantly higher APR than standard purchases. Currently, many cash advance rates are near 30%. Furthermore, cash advances usually do not have a grace period. Interest begins to accumulate the very same day you take the money.
A balance transfer occurs when you move debt from one credit card to another. This is often done to take advantage of a lower rate. Many cards offer a promotional 0% APR on balance transfers for a set period, such as 12 to 18 months. Once that promotion ends, the remaining balance will move to a standard balance transfer APR, which is often similar to the purchase APR. If you are actively comparing payoff options, our balance transfer card comparison is the most relevant place to start.
The penalty APR is the highest rate a card can have. It is triggered if you violate the terms of your agreement, most commonly by making a payment that is 60 days late or more. This rate can stay in effect for six months or longer. If you make six consecutive on-time payments, the issuer is often required to review the account and potentially lower the rate back to the standard level.
A single card often displays a very low rate that eventually changes to a higher one. This is common with "introductory" offers.
It is a common mistake to think the 0% rate is permanent. If you have a $5,000 balance on a 0% intro card and the period ends, that balance will suddenly start accruing interest at the standard rate, which might be 24% or higher. If you are trying to avoid surprise interest, it can help to review how to pay a credit card with another credit card before moving debt around.
Most credit cards in the US use variable APRs. This means the interest rate is not set in stone. Instead, it is tied to an index, usually the US Prime Rate.
When the Federal Reserve changes interest rates, the Prime Rate moves. When the Prime Rate moves, your credit card APR moves with it. This can happen without the bank giving you a 45-day notice because the change is based on a public index rather than a specific decision by the bank to target your account.
A fixed APR, which is much less common today, stays the same regardless of market fluctuations. However, a bank can still change a fixed rate if they provide you with advance notice and give you the option to cancel the account.
If you use your card for different types of transactions, your monthly statement will look more complex. The bank is required to show you a breakdown of each balance category and the APR associated with it.
For example, your statement might show:
If you have multiple APRs and you pay more than the minimum amount due, federal law dictates how that extra money is applied. The Credit CARD Act of 2009 requires card issuers to apply any amount over the minimum payment to the balance with the highest APR first.
This is a benefit for the consumer. It ensures that the most expensive debt is paid off the fastest. However, the bank is allowed to apply your minimum payment to whichever balance they choose, which is usually the one with the lowest interest rate.
Find the Daily Rate
Divide your APR by 365. If your APR is 24%, the math is 24 / 365 = 0.0657%. This is the percentage you are charged each day.
Determine the Average Daily Balance
The bank looks at your balance at the end of every day in the billing cycle, adds them all together, and divides by the number of days in the month.
Calculate the Daily Charge
Multiply your average daily balance by the daily periodic rate. If you have a $2,000 balance at a 24% APR, the daily interest is roughly $1.31.
Monthly Total
Multiply the daily charge by the number of days in the billing cycle. For a 30-day month, that $1.31 per day becomes $39.30 in interest for the month.
Even for the same credit card, two people might have different APRs. Banks assign rates based on several criteria.
If you find yourself carrying balances across multiple interest rates, there are ways to minimize the cost.
When you are looking for a new credit card, the headline APR is just the beginning. Different cards have different structures for their multiple rates. Some might offer a great purchase APR but a predatory penalty rate. Others might have a high purchase APR but offer an industry-leading balance transfer promotion.
We provide side-by-side comparison tools that break down these different rates clearly. Instead of digging through pages of fine print for five different banks, you can see the purchase, cash advance, and balance transfer rates in one place. This transparency helps you choose a card that fits how you actually use credit. For example, if you never plan to carry a balance, a card with a high APR but great rewards might be fine. If you need to pay off existing debt, a card with a long 0% intro period on transfers is likely a better choice. For more background on reward structures, our cash back card guide is a good companion read.
