Calculating the APR
Credit card APR (Annual Percentage Rate) isn't applied annually. It's applied **daily**. Most banks use your "Average Daily Balance" to calculate the finance charge for the statement period.
The Daily Math
(APR / 365 days) * Daily Balance = Daily Interest
The Minimum Payment Trap
Credit card companies set minimum payments extremely low—usually just the current month's interest plus 1% of the principal. This ensures they collect interest from you for decades.
Financial Impact
Break the Cycle.
"If your APR is 25%, you are working 1 week out of every month just to pay the bank. Switch to a lower rate card or prioritize payoff to reclaim your time."
