A B C I M R S

A

Annual Fee

A yearly charge for holding a credit card. Can range from $0 to $700+ for premium cards. Must be weighed against rewards value.

Annual Percentage Rate (APR)

The annual interest rate on a credit card, used to calculate daily and monthly interest charges on outstanding balances.

Avalanche Method

A debt repayment strategy where you pay minimums on all cards then direct extra funds to the highest interest rate card first.

B

Balance Transfer

Moving an existing credit card balance to a new card, often to access a 0% or low promotional interest rate.

C

Cash Advance

Withdrawing cash using a credit card. Attracts immediate interest (no interest-free period) at higher rates than purchases.

Credit Limit

The maximum amount you can charge to your credit card. Lenders assess the full limit — not just the balance — when evaluating new credit applications.

I

Interchange Fee

A fee paid by merchants to card networks for processing transactions. Rewards programs are largely funded by interchange fees.

Interest-Free Period

The period (typically up to 55 days) during which no interest is charged on purchases, provided the full balance is paid by the due date.

M

Minimum Payment

The smallest amount you must pay each month to avoid penalty fees. Paying only the minimum results in very slow debt reduction and massive interest costs.

R

Revert Rate

The standard purchase rate that applies after a promotional period (such as a 0% balance transfer period) ends.

Rewards Program

Points, cashback or miles earned on card spending. Only valuable if the balance is paid in full each month; otherwise, interest costs outweigh rewards.

S

Snowball Method

A debt repayment strategy where you pay minimums on all cards then direct extra funds to the smallest balance card first.
