Fact checked

When you use a credit card, you’re essentially borrowing money from the account’s credit limit. So just like any other loan, interest may be charged on the balance. How and when this interest is charged can have a huge impact on what you’ll pay for the use of your credit card.

To make sure your credit card works for you, here you’ll find answers to the most common questions about interest, including the different rates that may apply and when it’s charged. We also look at how you can compare credit card interest rates and take advantage of interest-free days so you can avoid interest charges.

What are credit card interest rates and how do they work?

Interest rates are a type of fee that’s charged when you borrow money. With credit cards, interest rates are calculated as a percentage of your balance and shown as an annual or per annum figure.

Most credit cards also have different interest rates for different types of transactions, with the most common being a purchase rate and a cash advance rate. You can learn more about different types of interest rates below.

How is credit card interest calculated?

The interest rate on credit cards is normally shown as an annual figure. But most credit card companies calculate interest on a daily basis and then add the charges to your account at the end of each statement period. To determine your credit card interest amount, your daily outstanding balance is multiplied by the daily interest rate on your credit card. These daily calculations are then added together at the end of the statement period to get the total interest due. The daily interest rate is calculated by dividing the EIR by 365 days.

Compound interest costs

The way credit card interest is charged is known as “compound interest” because it is calculated daily. This means that you could end up paying interest on your interest charges. The good news is that you can cut down on interest costs any time you make a repayment, because that will also affect the daily interest calculation.

Types of credit card interest rates

Here are the most common types of interest rates you’ll find on credit cards:

  • Purchase interest rate. The purchase EIR is the interest you are charged when you use your credit card for making payments in retail outlets or online.
  • Cash advance interest rate. The cash advance EIR is the interest rate you are charged when you use your credit card for withdrawing cash from ATMs or cash equivalent transactions, like buying gift cards or gambling.
  • Balance transfer interest rate. This is the interest rate you are charged when transferring an existing credit card debt to a new card.
  • Promotional interest rate. Many credit card companies offer new customers promotional interest rates for purchases and/or balance transfers. This promotional interest rate is only available for a limited time, with the standard interest rate applying after that. For example, a card may offer you 0% interest on balance transfers for the first 12 months. If you didn’t pay off the balance transfer during the first 12 months, the standard rate for balance transfers would apply to the debt.

Even the smallest difference in credit card interest rates can have a huge impact on your account costs. So when you’re looking for a new card, make sure you compare both the standard and promotional interest rates to help you find one that suits your needs.

Comparing credit card interest rates

To show you how important it is to compare interest rates, let’s say you have a balance of S$1,000 on a credit card with an interest rate of 20.99% p.a. If you only made monthly payments of S$50 on this debt, it would take you around 2 years and to pay off your balance and cost you about S$212 in interest.

On a credit card with an interest rate of 15.99% p.a., it would still take around 2 years to pay off your balance but would cost you S$153 in interest. That’s a saving of S$53 compared to the card with a higher rate, which is basically another monthly repayment. The bigger the difference in rates, the greater these potential savings would be.

What else do I need to know?

As well as interest rates, make sure you consider the following when you’re looking for a new credit card:

  • Interest-free days. Many credit cards offer up to a certain number of interest-free days on purchases when you pay your account balance in full by the due date on your statement. For example, up to 23 days interest-free. This gives you a way to avoid interest charges for spending on your credit card.
  • 0% interest rate offers. If you get a credit card with a promotional 0% interest rate, it may only apply for certain types of transactions. For example, you could get 0% interest on balance transfers for 12 months but still have to pay the standard variable interest rate for purchases. There is also a range of credit cards that offer introductory 0% interest rates on both purchases and balance transfers, although standard rates will apply at the end of the promotional period.
  • Annual fee. Most credit cards charge an annual fee, which could also add to your account balance. Remember to factor this cost in when your comparing credit cards and also when you’re budgeting for interest costs and repayments.
  • Other features. Many credit cards offer complimentary extras such as insurance or rewards, which could help offset the cost of the annual fee and interest charges. Just remember to weigh the value of the benefits against potential costs so you can decide if a card is worth it based on your spending habits and goals.
