How To Calculate Interest Charges On Credit Cards
Average Daily Balance Method
The most widely used method credit card issuers use to calculate the monthly interest payment is the average daily balance, or the ADB method. Since months vary in length, credit card issuers use a daily periodic rate, or DPR, to calculate the interest charges. DPR is calculated by dividing the APR by 365, which is the number of days in a year.
Daily Periodic Rate, DPR = |
365 |
Then find the ADB. The equation for finding this is a bit more tedious, but just add up all the balances for each day in the statement billing cycle and divide by the total number of days in the billing cycle.
ADB = |
+ + … + |
number of days in the billing cycle |
Finally, multiply this by the Daily Periodic Rate calculated before it and the number of days in the billing cycle to determine the interest for that month’s statement.
Monthly interest payment = DPR × ADB × number of days in the billing cycle
Example: Jon needs help calculating the interest payment for one of his credit cards in the month of June. It carries an APR of 15%. Calculate his DPR using the equation above:
DPR = |
How Much Will Your Business Actually Pay
The charges that your business will pay depend on several factors, including the processing method, the credit card network, and whether the customer chooses to use a credit card or debit card. Visa charges between 1.4% and 2.5% for a transaction, while MasterCard charges between 1.5% and 2.6%. If a customer uses Discover or American Express, you could pay anywhere between 1.55% and 3.5%.
If youre a business that has a large number of customers who use their credit cards, your fees will be different from those paid by a smaller store. Your charges depend on the processor that you choose and several other aspects of your situation.
How Payments Are Applied To Your Balance
If you dont pay your entire credit card balance by the due date, youll pay interest.
Different interest rates may apply to different types of credit card transactions. For example, cash advances often have a higher interest rate than purchases. This means different interest rates will apply to your balance depending on how you use your credit card.
Typically, your minimum payment will apply it to the portion of your balance with the lowest interest rate. Any amount you pay over the minimum payment applies in one the following two ways:
- to the portion of the balance with the highest interest rate
- proportionally to the entire balance
A credit card issuer that is a federally regulated financial institution can decide how it will apply your minimum payment to your balance.
Check your credit card agreement or ask your credit card issuer how it applies a payment to your balance.

How To Minimise Interest Charges
When offers apply
If theres a 0% introductory or promotional interest rate on your account, as long as you make transactions within any specified dates, you wont be charged interest for a set period of time -usually a number of months. Its important to know that standard interest rates will apply to any remaining balances when a promotional rate expires.

When offers dont apply
Even if there arent promotional interest rates available, if you pay your credit card statement balance in full and on time every month, you wont be charged interest on card purchases. However, this might not be realistic for people using a credit card to spread the cost of larger purchases, or to consolidate a number of balances.
If you cant pay your whole statement balance each month, its a good idea to pay as much as possible to keep any interest costs to a minimum.
What Is Credit Utilisation

Your credit utilisation ratio describes what percentage of the credit available to you, you are actually using.
Let’s say you have a credit card with a limit of £1,500. If, over the course of the month you spend £750 on the card, this would make your credit utilisation 50%.
Credit utilisation doesn’t just work across one card, you can also calculate how much of your total available credit limit you are using.
Here’s another example:
If you have three credit cards, one with a limit of £250, one with £1,500 and another with £2,000 the total amount of credit available to you would be £3,750. If you then spent £1,125 across all of those cards your overall credit utilisation would be 30%.

So Whats The Right Amount Of Credit To Use
If youre trying to increase your credit scores as much as possible, then you should use as little of your available credit as possible. VantageScore recommends keeping your utilization rate below 30%, but thats not necessarily a shortcut to better credit. Depending on the state of your accounts, it might also benefit you to keep a lower credit utilization rate across the board, not just in total.
But there may also be such a thing as using too little credit. In some cases, its better to use at least a little of your available credit with each account, because using some can be taken to show youre actively using and managing your credit rather than keeping your cards in the sock drawer.
Fortunately, a perfect utilization rate isnt required for an excellent credit scores. According to FICO, 7% is the average utilization rate for people with a FICO Score 8 of at least 785.

The Dangers Of Minimum Credit Card Payments
Unfortunately, too many American’s fall into the trap of charging for items they can’t immediately afford, and then instead of finding a way to pay off the balance they only make minimum payments. Although you may think that by making a minimum payment you are handling your debt, you are putting yourself in a dangerous financial situation.
Are you asking yourself “how could it possibly be a bad for me to make the minimal amount payments on my credit card bills?” It is a confusing concept when so many credit card companies advertise the many benefits of using their money while only needing to make small monthly payments. However, the choice to make minimal payments comes with dangers. Check out these three negative consequences that come from not immediately paying off your balance and only making minimal payments each month.
The Exception To Lower Is Better
But dont avoid your cards completely. Most credit scoring models view 1% utilization as better than 0%.
If you pay off your full balance early, before a statement is generated, your next statement will show a $0 balance. This is the number that will show up on your credit reports. But if only $0 balances are reported to credit bureaus, credit scoring models may eventually consider the account inactive.
We recommend paying your full statement balance between the time you get your statement and the due date. If you spend a lot one month and are concerned about high utilization, you could make a partial payment early, before the statement is generated.
However, if youre preparing to apply for new financing, it can be a good idea to pay your full balance before the statement closing date. You should do this for a couple of months in advance. This should result in very low utilization on your credit reports and, quite possibly, a boost in your credit scores.

At one time in your life, you have likely noticed a boost in the amount of available credit on your credit card. While a credit limit increase may not have been something that you asked for or even wanted, it means that your card issuer thinks you are an above-average borrower.
But what if you took out a new credit card and the issuing company started you off with a fairly low ? What if that limit wasnt raised after the first year? What should your credit limit be? Should you ask for an increase? The answer to the last question is yes, and there are several good reasons why.
Whats Included In Your Credit Utilization Rate Calculation

Unfortunately, this question doesnt have just one answer. Different consider different types of accounts when they calculate your utilization rate.
For example, in October 2019 spokespersons for both FICO® and VantageScore® told us they generally dont include any paid-off, closed accounts that are in your credit reports when calculating utilization rates.
FICO might include a closed account that still has a balance, like an account thats gone unpaid and is closed by the card issuer. But VantageScore doesnt include any closed accounts when calculating credit utilization rates.
The FICO credit-scoring model doesnt consider home equity lines of credit, or HELOCs, when determining utilization, but the VantageScore credit-scoring model does.
All FICO scores and most VantageScore scores consider only the most recently reported credit limits and balances as part of the utilization equation. As a result, if you use your accounts for crucial expenses and your utilization increases, you may see a dip in your credit scores. But your scores could increase again once you pay off those expenses and bring down your utilization.
The latest VantageScore scoring model, VantageScore 4.0, also considers your utilization rates over time as part of whats known as trended data. And some creditors may consider your historical utilization when reviewing your application, even if that history doesnt impact the credit scores they receive.

The rule says that you first need to calculate the periodic rate by dividing the nominal rate by the number of billing cycles in the year. Then the balance gets multiplied by the period rate in order to have the corresponding amount of the finance charge.
Finance charge calculation methods in credit cards
Basically the issuer of the card may choose one of the following methods to calculate the finance charge value:
-
First two approaches either consider the ending balance or the previous balance. These two are the simplest methods and they take account of the amount owed at the end/beginning of the billing cycle.
-
Daily balance approach that means the lender will sum your finance charge for each day of the billing cycle. To do this calculation yourself, you need to know your exact credit card balance everyday of the billing cycle by considering the balance of each day.
-
Adjusted balance method is a bit more complicated as it subtracts the payments you make during the billing period from the balance at the cycles beginning.
