Remember: Actual card and loan conditions depend on the financial institution's approved terms and contract.

Understand the three dates

Purchase date, statement date, and payment due date are different.

Full payment is the simplest cost control

Paying the full statement balance by the due date generally avoids revolving-interest cost.

A limit is not a budget

Approved credit capacity does not mean you can sustainably spend that amount.

Put cards inside the household budget

Card spending is still spending.
