How Credit Card Interest & Balance Payoff Works
Credit cards are revolving unsecured debt facilities that calculate finance charges based on your Average Daily Balance. When you carry a balance from month to month, interest accrues daily at your Daily Periodic Rate (APR divided by 365) and compounds every billing cycle.
Because credit card APRs average between 18% and 29%, carrying debt is one of the most expensive forms of consumer borrowing. Understanding how payments are distributed between interest and principal is critical to avoiding prolonged debt cycles.
The Minimum Payment Trap Explained
Card issuers typically set minimum monthly payments using one of two formulas:
- Formula A:
Accrued Monthly Interest + 1% of Principal Balance(subject to a $25 or $35 minimum). - Formula B:
2.0% to 2.5% of the Total Balance.
On an $8,000 balance at 18.0% APR, your initial minimum payment is roughly $200 ($120 interest + $80 principal). As the balance drops, the required minimum payment also falls, slowing principal reduction to a crawl. Paying only the minimum takes over 20 years to eliminate the debt and costs more than $8,500 in pure interest!

Frequently Asked Questions
Credit card issuers typically calculate interest daily using your Daily Periodic Rate (DPR), which is your annual APR divided by 365. Each day, the DPR is multiplied by your average daily balance and compounded monthly onto your statement billing cycle.
