How does credit card interest work?

Uncertain about how to utilize the above calculator? Let’s delve into four terms commonly found in the details of your credit card statement and cardholder agreement:

Understanding these key terms is crucial for navigating your credit card statements and agreements:

Annual Percentage Rate (APR) – This is the annualized rate of interest charged on any outstanding balance if it’s carried over to the next billing cycle. Different APRs may apply to various types of transactions like purchases, balance transfers, and cash advances. The Purchase APR is the one most cardholders are familiar with, as it applies to purchases made with the card.

Daily Periodic Rate (DPR) – The daily interest rate applied to your outstanding balance. It’s calculated by dividing the APR by the number of days in a year.

Average Daily Balance (ADB) – This is the average balance you carry on your card each day throughout the billing cycle.

Compounding – Interest compounds when the accrued interest from the previous day is added to the outstanding balance, and interest is then charged on that new total. This process continues until the end of the billing cycle.

Now, let’s break down the interest calculation methods employed by credit card issuers. They convert your APR into a DPR and then calculate your daily balance. This could be an Average Daily Balance over the month or an approximation of your balance each day. Each day’s interest charge is then added to the next day’s average balance until the end of the billing cycle, compounding the interest. Finally, any payments or credits are subtracted from the total balance.

If this explanation feels a bit overwhelming, don’t worry! We’ll take it step by step to ensure you grasp each part of the process.

How to calculate your interest payments manually

To begin, calculate your Daily Periodic Rate (DPR) by dividing your Annual Percentage Rate (APR) by either 365 or 360, depending on your card issuer’s approach. For instance, if your APR is 18.25% and divided by 365, your DPR would be approximately 0.05%.

Next, determine your Average Daily Balance by adding up your daily credit card balances for the billing cycle and dividing the total by the number of days in the cycle.

For example, let’s assume your Average Daily Balance is $1,000. On the first day, you’d owe interest of $0.50 ($1,000 x 0.05%). On the second day, your new balance of $1,000.50 would incur another $0.50 in interest, plus a fraction of a penny. This process continues, with interest compounding daily, until the end of the billing cycle.

Assuming a 30-day billing cycle and no additional transactions or payments, you’d owe approximately $15.11 in interest at the end of the cycle.

Skip the math and go automated in 3 easy steps

To utilize our credit card interest calculator efficiently, follow these straightforward steps:

  • Enter your card’s current balance.
  • Input the current interest rate (APR) applied to your card balance.
  • Enter your estimated monthly payment amount or the number of months you plan to take to repay the debt.

By following these steps, you can quickly assess various repayment scenarios and their respective impacts on the total interest paid. This automated approach saves you from the tedious manual calculations typically associated with determining credit card interest.

How can I save on interest?

Paying too much in credit card interest can gradually eat away at your financial resources, throw off your budgeting and prevent you from reaching your financial goals. But there are ways you can reduce the amount of card interest you pay.

Pay your balance in full and on time

Paying off your credit card balance in full by the due date is the simplest and most effective strategy to avoid paying any interest. By clearing your entire balance each month, you prevent any carried-over amounts from accruing interest in the next billing cycle. Additionally, consistently paying off your balances on time can contribute to building a high credit score, which opens doors to better credit card offers and favorable terms for other financial products like mortgages or loans.

Exercise extra caution with charge cards, such as those issued by American Express, which differ from traditional credit cards. Charge cards typically lack a grace period, meaning the balance is due immediately upon statement issuance. Consequently, interest rates on these cards tend to be higher than average, making it essential to manage spending carefully to avoid accumulating debt.

Find a card with a better interest rate

Carrying a balance on your credit card from month to month may occur for various reasons:

  • Making a significant purchase without depleting savings
  • Facing unexpected emergency expenses
  • Choosing to allocate cash to other financial priorities

At some point, many individuals find themselves in this situation, and having a credit card with a low purchase interest rate can offer significant savings. While most Canadian credit cards typically have a purchase interest rate around 20%, some cards offer substantially lower rates, potentially halving the interest expenses incurred on carried balances.

Complete a balance transfer

Transferring your existing credit card balances to a low-interest or balance transfer credit card can be an effective strategy for paying down your balance more efficiently. Balance transfer promotions offer the opportunity to shield your credit card balance from high APRs, potentially reducing or even eliminating the interest charges that would have accrued at your old rate. This allows your regular monthly payments to make a more significant impact on reducing the principal balance.

Consolidate debt with a loan

Consolidating multiple credit card balances into a single loan can be an effective debt management strategy, particularly for individuals with balances spread across various cards with different interest rates. By consolidating these balances into a single loan with a lower interest rate compared to the average rate across your cards, you can streamline your payments and potentially reduce your overall interest expenses. This approach simplifies your debt obligations, offering the convenience of a single monthly payment and the potential for lower monthly payments compared to managing multiple credit card balances separately.
