Credit Card Interest Rates Explained
Understand credit card interest rates, APR, finance charges, minimum payments and the situations in which interest may be charged — before a credit card balance becomes expensive.
What does a credit card interest rate actually mean?
A credit card interest rate is the rate used to calculate finance charges on eligible outstanding balances. The actual amount you pay depends on the card's terms, outstanding balance, payment behaviour and how the issuer calculates charges.
Credit card issuers disclose annualised percentage rates and should explain the methodology used to calculate applicable charges. :contentReference[oaicite:1]{index=1}
Understand the rate structure
Do not compare only one percentage. Review the full pricing structure.
Four things to check before judging a credit card rate.
The headline rate is only one part of the cost. Look at the complete pricing and repayment terms.
Annualised Rate
Check the APR disclosed for purchases and whether a separate rate applies to cash advances.
Payment Behaviour
Understand what happens when the total amount due is not paid by the payment due date.
Other Charges
Review annual fees, late-payment charges, cash-advance charges and other applicable fees before comparing cards.
Card Terms
Read the Most Important Terms and Conditions and the issuer's latest schedule of charges.
