Frequently Asked Questions

Fact-checked guidance grounded in credit card interest daily compounding math.

How does credit card interest compound?

Credit card interest is calculated daily using your Annual Percentage Rate (APR) divided by 365. Monthly interest is charged on your average daily balance. Early in payoff, a large portion of your monthly payment goes toward interest charges rather than reducing your principal balance.

Why is paying only the minimum credit card payment dangerous?

Minimum credit card payments are usually set at just 1% to 2% of your balance plus interest. Paying only the minimum extends your payoff timeline to 15–30+ years and can cause total interest charges to equal or exceed the original amount you borrowed.

Is it better to solve for a fixed payment or a target payoff date?

If you have a strict monthly budget, solving from a fixed payment tells you exactly when you will be debt-free. If you have a specific goal (e.g. paying off a card in 24 months before buying a home), solving from a target date tells you the exact monthly payment required.

How much can extra payments save on a high-APR credit card?

Because credit card APRs average 20% to 25%, every extra dollar paid reduces principal immediately. Adding just $50 or $100 extra per month above your base payment often cuts payoff time in half and saves thousands of dollars in interest.
