💡 Money Facts
Credit Card analysis is used by millions of people worldwide to make better financial decisions.
— Industry Data
Financial literacy can increase household wealth by up to 25% over a lifetime.
— NBER Research
The average American makes 35,000 financial decisions per year—many can be optimized with calculators.
— Cornell University
Globally, only 33% of adults are financially literate, making tools like this essential.
— S&P Global
The average American carries $6,501 in credit card debt at 22.77% APR — paying only minimums, it takes 28 years and costs $12,000+ in interest to pay off. Credit card companies earned $130 billion in interest charges in 2023. This calculator shows exactly how much more you're really paying.
⚠️ The Minimum Payment Trap
Minimum payments are designed to keep you in debt. Most of each payment goes to interest, not principal. A $5,000 balance at 24% APR with minimums only takes 22+ years and $8,900+ in interest. Paying $200/month instead cuts it to under 3 years and ~$2,000 interest.
💰 Balance Transfer Math
A 0% balance transfer with a 3% fee: $5,000 × 3% = $150 fee. If you pay $334/month for 15 months, you pay off the balance with zero interest. Compare: $5,000 at 22% for 15 months = ~$1,400 in interest. The transfer saves ~$1,250. Pay it off before the promo ends.
🏔️ Avalanche vs Snowball
Debt Avalanche: Pay highest APR first. Saves the most money. Best for disciplined payers. Debt Snowball: Pay smallest balance first. Quick wins, fewer accounts. Best for motivation. If APRs differ by 5%+, avalanche usually saves hundreds. Similar APRs? Snowball can work.
📊 Credit Utilization
Utilization = (balance ÷ credit limit) × 100. Under 30% is good; under 10% is ideal. High utilization hurts your score. Pay before the statement date to report lower balances. Don't close cards after payoff—it reduces available credit and can raise utilization.
📊 Key Numbers
❓ Frequently Asked Questions
How does credit card interest work?
Credit card interest compounds daily. Your APR is divided by 365 to get a daily rate, then applied to your average daily balance. Interest = Balance × (APR/12/100) each month. Paying only minimums means most of your payment goes to interest, not principal—extending payoff for decades.
What is the difference between APR and APY on credit cards?
APR (Annual Percentage Rate) is the stated yearly rate. APY (Annual Percentage Yield) reflects compounding. For credit cards, effective APY ≈ (1 + APR/12)^12 - 1. A 22% APR compounds to ~24.4% APY. Credit cards use APR in disclosures; the real cost is higher due to daily compounding.
What is the minimum payment trap?
Minimum payments are designed to keep you in debt. Typically 1-2% of balance plus interest—most goes to interest. $6,501 at 22.77% APR with $130 minimum takes 28 years and $12,000+ in interest. Paying even $50 extra monthly can cut years off and save thousands.
When does a balance transfer make sense?
Balance transfers work when you can pay off the debt within the 0% promo period. A 3% transfer fee on $5,000 = $150. If you pay it off in 15 months at 0%, you save thousands vs 22% APR. Never use the new card for purchases during the promo—payments go to 0% balance first.
Debt avalanche vs snowball: which is better?
Avalanche: pay highest APR first—saves the most money mathematically. Snowball: pay smallest balance first—psychological wins, faster account closures. Avalanche is optimal for interest; snowball works better for motivation. If APRs are similar, snowball can be worth the small extra cost.
What is credit utilization and why does it matter?
Credit utilization = (total balance ÷ total credit limit) × 100. It affects ~30% of your FICO score. Under 30% is good; under 10% is ideal. Maxed-out cards (90%+) can drop scores 100+ points. Pay down balances before statement date to report lower utilization.
