What is Credit Card Interest Rate?

Credit card interest rate, called APR (Annual Percentage Rate), represents borrowing costs. Essentially, it's the price for credit use. Rates vary based on creditworthiness. Typically, they range from 12% to 25%.

Interest compounds daily on balances. Importantly, it applies when carrying debt. Consequently, small balances grow quickly. Therefore, understanding your rate is crucial.

Credit Card Interest

The Interest Formula

Interest = Balance × (APR ÷ 365) × Days

This formula calculates your interest charges based on daily compounding.

How Credit Card Interest Works

Credit card interest compounds daily on unpaid balances. First, your APR converts to a daily rate. Next, each day's interest adds to the principal. Then, subsequent interest calculations include previous interest. Consequently, debt grows exponentially without payments.

Most cards have grace periods. However, they only apply with full payments. Otherwise, interest accrues immediately. Therefore, carrying balances becomes expensive quickly. Ultimately, understanding this process helps reduce costs.

Most cards use daily compounding interest. However, specific terms may vary slightly. Always review your cardholder agreement. Some cards have different grace periods or calculation methods.

How can I avoid paying credit card interest?

Pay your full balance monthly before the due date. Take advantage of grace periods. Consider 0% APR balance transfer cards. Always make payments on time to avoid penalty rates.

Why is my interest charge higher than calculated?

Previous unpaid interest may be included. Additional purchases could increase the balance. Some cards have different compounding methods. Check for cash advance fees or penalty rates.

Does making multiple payments reduce interest?
