What Is Credit Card Interest And Why Does It Matter
You can think of APR as the cost of borrowing money. The credit card issuer covers the cost of your purchases upfront, while you get to pay them back over time. In exchange, they charge you a fee for this service in the form of interest.
Credit card interest is generally described in terms of APR, which stands for;annual percentage rate. However, credit card interest is actually calculated on a daily basis and then charged monthly at the end of a billing cycle.
To understand how much a purchase made with your credit card will really cost, you need to understand how interest is calculated and when it is applied. That way, youll know exactly how much interest youll pay on your credit cards.
For example, if you wanted to pay off a $2,000 purchase over 24 months, you might end up paying closer to $2,400 when you factor in interest charges. This may be worth it to you, or maybe you can be more aggressive with your payments and save, say, $150 in the long run.

How Does A Purchase Apr Work
The purchase APR is the rate of interest the credit card company charges on purchases you make with the card if you;carry a balance;on the card, which is what its called when you dont pay off your balance on your monthly statement and roll it over onto the next months bill.
But some credit cards come with purchase APR promotions that offer an introductory purchase APR or;low interest rate;on new purchases made with the card for a set amount of time. You may see intro APRs for purchases that last anywhere from just a few months to 21 months or more.
An introductory purchase APR offer can give you a way to pay off new purchases at a lower interest rate, sometimes even;as little as 0%. Once the promotional time frame ends, the regular purchase APR will take effect. This is usually a higher interest rate that youll begin paying on both new purchases;and;existing purchases that you havent paid off before the intro period ended.

A credit card can either have a fixed APR or a variable APR. A;fixed APR;typically remains the same, but it can change in certain circumstances, such as if your payment is more than 60 days late or when an introductory offer expires. A;variable APR;usually changes with the prime rate, as published in the Wall Street Journal. Many variable interest rates start with the prime rate, then add a margin. The result is your variable APR.
The purchase APR will be used to calculate how much interest youll pay on an outstanding purchase balance, if you have one. If you have excellent credit , you may be more likely to qualify for a lower interest rate because a credit card company may consider you a lower-risk customer.
If you have fair or poor credit , you may get a higher interest rate if youre approved for the card. This means itll cost you more every time you carry a balance with your card, so be sure to pay off your balance on time and in full every month, if possible.

How Long Before Interest Is Charged On A Credit Card
Most credit cards provide an interest-free grace period of around 21 days starting from the day your monthly statement is generated, to the day your payment is due. However, if you don’t pay it during that time, an interest charge will go into effect and you will end up with a balance that rolls over to the next month.
Transferring Your Balance To A New Card
You have seen and no doubt been tempted to get a new credit card with a lower introductory rate if you transfer your current credit card balance.
This certainly could work for you if you have a plan and the discipline to not increase the balance on the new card, cut up or stop using the card you have just transferred the balance from and aggressively pay down the amount owed versus making the minimum monthly payment.
The first thing to check before transferring the balance is the length of time the low-interest introductory offer lasts and if you think you can realistically pay down the majority of the debt during that period.
Then you need to understand what the rate will be when the introductory offer is over and estimate what your balance will be at that time.
The standard rate on the new card may be greater than the old card and ultimately cost more in the long runplus you need to confirm if there are any transfer fees or additional costs.
Remember, if you use the new card, new purchases made will be charged at the standard interest rate as the introductory rate is only for balance transfers. Any payments you make will be applied to the amount transferred not the new purchases.

When Does Interest Start To Accrue On A Credit Card
Understanding how you’re charged interest on your credit card is the key to knowing how to manage your card debt. Here’s how it works.
DPR is just another way of saying what your daily interest charge is. That’s calculated by taking your credit card’s Annual Percentage Rate and dividing it by 365, for all the days in the year.
So if your card has a 15.99% APR, your DPR would be 0.0438%.
The reason why credit card balances can quickly build up on cards with high APRs is because of compounding interest charges that occur on a daily basis.
At the end of each day, the interest charge is calculated and added to your balance for the next day. This continues every day for the billing period, so the interest you’re charged one day becomes part of the balance on which interest is charged the next day, and so on. At the end of the month, the lender will add up all of these daily interest charges and put it on your card as a finance charge.

How To Avoid Paying Credit Card Interest
Of course, none of these interest rate calculations are relevant if your card issuer waives the interest charges. Nearly all card issuers won’t impose interest charges when the entire statement balance is paid in full on or before the due date. The period of time between the statement closing date and the due date is called a grace period.
Technically, interest charges apply during this period, but they are waived if the entire balance is paid in full and on time. By law, credit cards that offer a grace period must give you at least 21 days to avoid interest by paying your balance in full. For more information, see “What Is a Good APR for a Credit Card?”
How To Close A Credit Card Account
Both the primary cardholder and the credit card issuer are able to close a credit card account at anytime. However, if your card has an outstanding balance at the time the account is closed, you are still responsible for paying it off in full.

What Determines A Credit Cards Interest Rate
As the CFPB explains, âThe credit card company may decide which interest rate to charge you based on your application and your credit history.â Generally, the higher your credit score, the lower your interest rate might be.
The interest rate, or APR, can either be variable or non-variable. A variable APR is often based on the prime rateâan index that most lenders use to set their own interest rates. And a variable APR could change when the prime rate changes. A non-variable APR typically stays the same, but it can change under certain circumstances. For example, your non-variable APR could increase if you make late credit card payments or miss payments, depending on your card issuerâs policy and your card terms.
A credit card may offer an introductory or promotional APR on purchases and balance transfers. After the introductory or promotional period ends, the rate will return to the standard APR disclosed in the cardâs terms.
If The Steps Above Seem Confusing Here’s An Example Of How To Calculate Apr Charge On A Credit Card:
If your current balance is $500 for the entire month and your APR rate is 17.99%, you can find your daily periodic rate by dividing your current APR by 365. In this case, your daily APR would be approximately 0.0492%. By multiplying $500 by 0.00049, you’ll find your daily periodic rate is $0.25. In order to calculate the monthly interest charges to your balance you simply need to multiply this daily periodic rate by the number of days in your billing cycle. For most credit cards the average billing cycle is about 30 days.
With this in mind, it is prudent to keep on top of payments each month in order to minimize this effect of daily compounding interest.

How Credit Card Interest Is Calculated
An average daily interest rate doesnt seem like much. But if you dont pay your entire statement balance by the due date, youre charged interest on the unpaid amount. Some lenders, like CIBC, calculate credit card interest using your average daily balance. Heres how it is calculated:
The total amount of interest you owe is added to your account at the end of the statement period.
For example, lets say you have an average daily balance of $500 with an APR of 20%. Your daily interest rate would be 20% divided by 365 days, giving you about 0.054%. To find how much interest you owe each day, multiply 0.054% by $500, which gives you $0.274. To get your total interest charges for the month, multiply your $0.274 by the number of days in your statement period, lets say 30 days. This gives you $8.22.
