Frequently Asked Questions
Everything you need to know about our credit card calculator
How is credit card interest calculated?
Daily rate (APR/365) times balance, compounding daily.
Daily interest = Balance × (APR/365). This compounds daily. If you carry a balance, interest accrues from purchase date with no grace period.
Why do minimum payments take so long?
Most of minimum payment goes to interest, not principal reduction.
Minimum payments (1-3% of balance) barely exceed monthly interest, so most goes to interest rather than principal. A $5,000 balance at 20% APR takes 30+ years at minimums.
How can I pay off credit cards faster?
Pay more than minimum, use avalanche or snowball method, consider balance transfer.
Pay more than minimum, focus on highest-rate card first (avalanche) or smallest balance (snowball), consider balance transfer to 0% APR card.
