Credit cards charge interest based on the outstanding balance carried over from one billing cycle to the next. When a person uses their credit card to make a purchase, the issuer lends them the money to complete the transaction. However, if the outstanding balance is not paid in full by the due date, the issuer will charge interest on the remaining balance.

Credit card interest is typically calculated based on the average daily balance method. This method involves summing up the balances for each day of the billing cycle and dividing it by the number of days in that cycle. The result is the average daily balance. Then, this amount is multiplied by the monthly interest rate to determine the interest charged.

The interest rate, also known as the Annual Percentage Rate (APR), is expressed as a percentage and can vary depending on the credit card and the individual's creditworthiness. Credit cards can have different interest rates for purchases, cash advances, and balance transfers.

It's important to note that credit card interest is applied only to the remaining balance after the minimum payment is made, and it compounds over time. This means that interest charges can accumulate and grow if the outstanding balance is not paid off promptly.

To avoid paying interest on credit card purchases, it is advisable to pay off the balance in full by the due date. If a balance is carried over, making only the minimum payment can result in significant interest charges and further increase the time it takes to pay off the debt.

Understanding how credit card interest works is crucial to managing debt effectively and making informed financial decisions.

What is the difference between purchase interest and cash advance interest on credit cards?

Purchase interest refers to the interest charged on the balance that arises from regular purchases made using a credit card. It is the interest you pay on the amount you owe for your purchases if you don't pay the full statement balance by the due date.

On the other hand, cash advance interest is the interest charged when you use your credit card to withdraw cash from an ATM, make a cash advance from a bank or financial institution, or use your credit card for other types of cash-like transactions. Cash advances generally have higher interest rates and start accruing interest right away, without any grace period.

In summary, purchase interest applies to the balance resulting from normal credit card purchases, while cash advance interest applies specifically to cash withdrawals or cash-like transactions made using the credit card.

How often is interest charged on credit cards?

Interest on credit cards is typically charged on a monthly basis. The interest is calculated based on the average daily balance of the card during the billing cycle. At the end of the billing cycle, the credit card issuer will assess the interest charge, which will be added to the outstanding balance and carried over to the next month if not paid in full.

How do credit card companies determine the minimum payment amount?

Credit card companies determine the minimum payment amount based on a few factors, including the outstanding balance, interest rate, and fees. Here are the main steps they follow:

  1. Percentage Calculation: The minimum payment is often calculated as a percentage of the outstanding balance. This percentage typically ranges from 1% to 3% of the total balance.
  2. Interest Charges: The company may add the interest charges accrued during the billing cycle to the minimum payment. If the outstanding balance is subject to a high-interest rate, the minimum payment will be higher.
  3. Fees: If there are any additional fees, such as late payment fees or annual fees, the credit card company may also include them in the minimum payment calculation.
  4. Floor Amount: Some credit card companies set a minimum floor amount, typically around $25. If the calculated minimum payment is lower than the floor amount, the minimum payment will be adjusted to meet the minimum threshold.

It is important to note that making only the minimum payment prolongs the time it takes to pay off the debt and increases the overall interest paid. Paying more than the minimum payment is advisable to reduce the debt faster and save on interest charges.
