Why It Is Important to Calculate Your Credit Card Interest

Learning how to calculate interest on a credit card should be an inescapable prerequisite before applying for a credit card. With so many credit interest calculators available for free online, there is no reason that anybody shouldn’t be able to calculate their monthly credit card interest. 

Most people wouldn’t take out a mortgage on a home before first understanding the specific terms and conditions regarding their home loan. Similarly, one should learn the skill of calculating credit card interest before they start to build up debt. 

According to U.S. News:

“A more subtle danger associated with ignoring the monthly credit card statement is personal finance complacency. When we don’t review and monitor our spending, we stop being in command of our finances, making it that much more difficult to reach our personal finance goals, whatever they may be.” 

Many people may feel that paying the minimum balance of $10 to $15 isn’t a financial hardship. However, by not calculating credit card interest with a credit card interest calculator, that minimum balance fee can end up being a permanent monthly expense for several decades.

If you continue to use your credit card or apply for other cards and build up the debt on those as well, the combination of those monthly payments can quickly become a major financial burden. 

Learning to calculate credit card interest with the help of a credit card interest calculator can help you take control of your debt before it spirals out of control. 



Furthermore, learning to calculate credit card interest may help you find a card with a better annual percentage rate. With the help of a monthly credit card interest calculator, you may be able to find that, by transferring your balance onto a low interest credit card, you may be able to increase the amount you pay on principal, getting yourself out of debt quicker. 

Lastly, learning to calculate credit card interest with the help of a credit card interest calculator will also give you leverage in your negotiations with the credit card company when you want to discuss the possibility of lowering your interest rate. 

According to LifeHacker.com,

“One thing you can do is call your credit card company and ask them to lower your interest rate. They might not always approve your request but in many cases they are open to working with you, and it never hurts to ask.” 

If you have learned how to calculate credit card interest and have compared interest rates on comparable cards, you might be able to convince your current credit card company to work with you to help you overcome your mounting debt.

What Can Happen When You Ignore How to Calculate Interest on a Credit Card

If you never learn how credit card interest is calculated, the temptation to overspend your budget is greatly increased. Many consumers, especially younger people without experience in maintaining a household budget, can quickly build up extensive debt. 

According to The Balance:

“Studies show that consumers spend more when they’re paying with credit cards than when paying with cash. In one study, participants were willing to spend as much as twice the amount when using credit cards versus using cash. It’s easy and convenient to spend money with a credit card and you don’t feel the ‘pain’ of cash leaving your wallet. This perhaps explains the amount of credit card indebtedness.”

Furthermore, consumers who never discover how to calculate interest on credit cards nor learn how to use a credit card interest rate calculator may settle for the minimum monthly payment that makes it all but impossible to pay off the principal on credit card debt. 

According to one article, only 29% of consumers pay off their balance in full each month, meaning that many of these spenders are investing much of their money in heavy interest payments. 

Without the help of a credit card monthly interest calculator, many consumers may end up paying more in interest than in principal. 

Lastly, by not learning how to calculate interest on credit cards, many consumers may be tempted to apply for a travel credit card or a card with high or special rewards. 

While these cards are great options for people who religiously pay off their balance each month, if you aren’t able to pay your balance in full and don’t know how to use a monthly credit card interest calculator, you may end up paying much more in interest. Travel and rewards cards usually have a much higher interest rate than other types of credit cards.

How Is Credit Card Interest Calculated?

The process of how to calculate credit card interest is often considered to be a top secret mathematical equation hidden in some vault by the top banks. The truth, however, is that anyone can calculate credit card interest even without the help of a credit interest calculator. 

As long as you can find the annual percentage rate on your card and your average daily balance, you can easily calculate your monthly interest payments.

Investopedia.com offers a simple and easy-to-understand example that will help you learn to calculate credit card interest. In the example below, “John” owes $200 on a credit card that charges 20% APR: 

  • “Principal: $2,000
  • Payment: $60 (3% of remaining balance)
  • Interest: $2,000 x 20% x 12 months = $33.33 [Simple Interest]
  • Principal Repayment: $60 – $33.33 = $26.67
  • Remaining Balance: $1,973.33 ($2,000 – $26.67)

These calculations are done every month until the credit card debt is paid off.

In the end, John pays $4,240 in total over 15 years to absolve the $2,000 in credit card debt. The interest that John pays over the 15 years totals $2,240, higher than the original credit card debt.”



How to Calculate Credit Card Interest by Yourself

To calculate your monthly credit card interest on your own without the help of a credit card interest calculator, simply multiply the average daily balance on your credit card by your daily interest rate by the number of days in the month.

You can find your daily interest rate by dividing the annual percentage rate on your card by 365 (the number of days in the year). 

Without the help of a credit card interest calculator, you will have to do this calculation each day of the year or month while you still have an outstanding balance on your credit card. The APR on your credit card will largely be determined by your credit score.
