Calculating Apr For Credit Cards
What Are The Other Costs And Interest Rate Charges On Credit Cards
The APR isn’t the only interest you may have to pay on your credit card debt.
You may also have to pay interest on:
-
Cash withdrawals
-
Balance transfers
-
Foreign currency transaction fees
-
Interest
Cash withdrawals: You are charged interest on cash withdrawals from the moment you take out the money. It is charged at a daily rate, making withdrawing cash on a credit card very expensive. You are much better withdrawing cash from an ATM via a debit card instead.
Balance transfers: Without a 0% balance transfer card, moving debt from one card to another could still cost you interest on your debt.
Foreign currency fees: Foreign currency fees mean you will be charged interest on your purchases abroad. You can minimise this cost with a travel credit card which does not charge currency fees. This is not the same as a card that gets you Airmiles or travel perks.
Unless you have a 0% interest card, the APR interest charge is added to your card balance. The interest is calculated on your total debt. This means you may have to pay interest on your interest.
How Do Credit Card Aprs Work
Fortunately, the math involved in calculating APRs isnt as complicated as you might think.
First, lets look at how a credit card issuer calculates APR. For credit card interest rates, the calculation starts with an index. A popular index to use is the U.S. prime rate . This rate is about 3 percentage points above the federal funds rate set by the Federal Reserve, which establishes U.S. monetary policy. The federal funds rate is the interest rate banks and credit unions charge each other to lend money on an overnight basis.
A credit card issuer then tacks on a margin, which is the percentage added to the prime rate or another type of index. The is typically tied to your credit score. A higher credit score usually results in a lower margin.

Why You Might Get Charged Interest With No Balance
Its understandably confusing to get a credit card bill that includes interest charges after bringing your account balance to zero. In some cases, it might end up being a mistake on the credit card companys part. But its most often a simple case of misunderstanding the credit card billing process.
So lets try to set the record straight, starting with a practical example.
Say you didnt pay your last monthly bill in full and owe $500 when your next months credit card statement becomes available on June 1. While you may have until June 30 to submit a payment before its considered late, interest will be assessed based on the average daily balance in the interim. That means the amount you owe will increase with each passing day.
So even if you pay off the full $500 balance by the due date , youll still owe money for the interest charged daily since June 1. As a result, when your new bill becomes available on July 1, your balance will be equal to the interest you racked up the previous month. If you do not pay this amount, you will incur interest on interest and will continue to do so until you have paid two consecutive bills in full, regaining your grace period.
What can you take away from this example?
Key Differences Between Apr And Nominal Interest Rate

There are a few key differences between APR and nominal interest rate, including the following:
-
Annual percentage rate calculates the total cost of borrowing per year, while nominal interest rate is the interest rate that a borrowed amount attracts.
-
Annual percentage rate makes use of the real interest rate that is adjusted for inflation and also includes other ancillary administrative costs of borrowing per year. The nominal interest rate does not consider inflation.
-
Annual percentage rate is used to compare loans realistically for a borrower, while the nominal interest rate used to compare loans may not be accurate.

How Is Credit Card Apr Calculated
First, itâs important to know that APR calculations can vary depending on the issuer.
When it comes to calculating your monthly payments, youâll actually have to do multiple calculations. But breaking it into individual steps can help simplify it all.
Step 1: Find Out How Frequently Interest Is Compounded
Before you jump into actual calculations, figure out how interest is compounded on your balance. In other words, figure out when interest is calculated based on how youâve used the card. Your account terms, customer agreement or both should provide this information.
Issuers can calculate interest in multiple ways. One example is the previous balance method, which bases interest charges on whatâs owed at the start of each billing cycle. But the CFPB says many credit card companies use a method thatâs based on the average daily balance.
Thatâs the method Capital One generally usesâand what Step 2 below is based on. But check with your issuer to see how it handles things.
Step 2: Calculate Your Average Daily Balance
If your issuer uses the average daily balance method, youâll need to know the balance you owe for every day of the billing cycle and the number of days in your billing cycle. From there you find the average by adding up the balance from each day and dividing it by the days in the billing cycle.
When you divide $15,750 by 30, the number of days in the billing cycle, you get $525. Thatâs your daily average balance. Keep it in mind for later.

That way, you can analyze how much value your card offers and what type of interest rates and terms you could expect from other cards in the future.

Disadvantages Of Annual Percentage Rate
The APR isnt always an accurate reflection of the total cost of borrowing. In fact, it may understate the actual cost of a loan. Thats because the calculations assume long-term repayment schedules. The costs and fees are spread too thin with APR calculations for loans that are repaid faster or have shorter repayment periods. For instance, the average annual impact of mortgage closing costs is much smaller when those costs are assumed to have been spread over 30 years instead of seven to 10 years.

How do Credit Card interest rates work?
Credit card interest rates are usually quoted in terms of .
A low or lower APR means you will have less interest to pay on your credit card debt. It will cost less to borrow money than if your credit card had a high APR. However, some credit cards have longer interest-free periods which will also affect the amount of interest you are charged.

How To Lower A Credit Card Interest Rate
You can try contacting your issuer and ask them to lower your rate. If your payment history has been consistently on time, they may be able to lower your APR by a percentage point or two.
If they are unable or unwilling to to offer you a lower rate, it may make sense to focus on improving your credit score so that youll qualify for better rates. Steps you can take include making sure youre making your payments on time and lowering your overall credit utilization by not carrying too high of a balance on your card.
If the card issuer still wont lower your rate, you may want to consider a card with a 0% APR balance transfer offer, especially if the ongoing rate after the promotional time period is lower than your current credit card.
Theres one other way you can avoid paying interest altogether: by paying your balance in full every month, if possible.
Fixed Apr Vs Variable Apr
The final difference weâll explain is between a fixed APR and a variable APR:
- Fixed APR: APR remains unchanged throughout the borrowing period.
- Variable APR: APR fluctuates due to being tied to a prime rate.
A fixed APR is thus more predictable than a variable APR, which is a function of the market conditions and the specific benchmark by which its value is influenced.

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.
What You Need To Know

Before you can calculate your exact payments, youll need to collect some information about your car and finances. The Consumer Financial Protection Bureau has a handy worksheet you can use to gather this information. Just fill in your details next to the example scenario.
First, figure out the overall value of the car and registration. This figure includes the sticker price of your car, along with any taxes, titling fees, warranties, and prior car loan amounts being rolled over into your new car loan. Once youve calculated this cost, you can subtract your down payment, along with any applicable rebates and the trade-in value of your previous vehicle.
Next, take a close look at the terms of the loan. To determine the car payment amount, you will need to know the length of the loan and the interest rate you will pay. The period of vehicle loans is generally stated in months, even if it lasts for years.
The CFPB has documented a steady rise in the length of car loans. Term lengths of six years or more made up just 26% of car loans issued in 2009. By 2017, these long-term loans made up 42% of car loans.

How To Calculate Your Daily Periodic Rate
Typically, dividing a credit cardâs APR by 365 will give you the daily periodic rate. Thankfully, itâs pretty simple. Hereâs how it works:
Step 1: Find the APR
In order to calculate the daily periodic rate, youâll need the APR for your credit card. You can find this on your . If youâre a Capital One customer, you can locate your APR in the section titled: âInterest Charge Calculation.â
Step 2: Do Some Division
The CFPB says you just need to divide your APR by 365âfor each day of the year. Thatâs what Capital One generally does. But sometimes issuers calculate the daily periodic rate by dividing by 360.
Daily Periodic Rate Example Calculation
Letâs say one of the credit cards in your wallet carries an APR of 19.99%. You can figure out the daily periodic rate by dividing the APR by 365âor by 360, depending on which number your issuer uses. If you divide 19.99% by 365, you get 0.0548%.
How To Calculate Your Monthly Apr
Calculating your monthly APR rate can be done in three easy steps:
For example, if you currently owe $500 on your credit card throughout the month and your current APR is 17.99%, you can calculate your monthly interest rate by dividing the 17.99% by 12, which is approximately 1.49%. Then multiply $500 x 0.0149 for an amount of $7.45 each month. Therefore, you should have been charged $7.45 in interest charges based on your $500 balance.
