How to Calculate Credit Card Interest Charges
1. Find your credit card’s APR
Your credit card’s APR will be listed in your cardmember agreement and on your monthly credit card statements.
2. Divide your APR by 365
An APR reflects the annual cost of borrowing, but credit card charges are assessed daily. Dividing by the number of days in a year gives you the daily interest rate – or daily periodic rate – for your credit card.
3. Multiply the daily interest rate by your average daily balance
Your average daily balance is the sum of your balances for each day in the billing period divided by the number of days in the billing period.
4. Multiply the resulting amount by the number of days in the billing period
When this calculation is done, you will have the interest charges due for the billing period. Just bear in mind that some details do vary by credit card company.
Whether you use WalletHub’s calculator or calculate credit card interest charges by hand, you should first understand the basics of how credit card interest works. We’ll highlight some key points below.
Key Things to Know About How Much Interest You’ll Pay on Your Credit Card
- If you pay off your balance in full by your due date, you won’t owe any interest.
- If you carry a balance from month to month, the interest you’ll owe depends on your Annual Percentage Rate (APR). That shows how much interest you’d pay in a year. But since credit card interest gets charged daily, your card’s interest rate is its APR divided by 365.
- Credit card interest compounds daily, which means the interest rate applies to your whole balance at the end of each day, including unpaid interest charges from previous days.
- The average APR among new credit card offers is 20.16%. But credit card APRs vary widely based on the applicant’s credit standing.
- Nearly all credit card APRs are variable, as opposed to fixed, meaning they’re based on a particular benchmark interest rate. This usually is the prime rate, which banks use when lending to each other.
- Many cards offer lower introductory APRs on purchases and balance transfers for a limited time, often starting at 0%. Once the introductory period ends, the APR will change to the normal rate.
There’s no way to tell you how much interest you’ll owe without knowing your card’s balance and APR as well as the monthly payment you can afford. But if you plug that info into WalletHub’s calculator, you’ll have your answer in no time.show less
