Credit card debt is the most expensive consumer debt most Americans carry. The average U.S. credit card APR has hovered above 20% throughout the 2020s, which means a $5,000 balance left on a card grows by roughly $1,000 in interest every year if no payments are made. Minimum payments — typically 1–3% of the balance — barely make a dent.
This calculator shows you the truth that issuers don't put on the statement: how long the balance takes to pay off at the payment you're making, how much total interest you'll pay, and how dramatically that changes if you add even a small extra payment each month.
The math is straightforward but the results are often shocking. An $8,000 balance at 22% APR paying only the $200 minimum takes about 5 years and costs over $4,000 in interest. Adding just $100/month cuts that to about 2.5 years and saves more than $2,000.
Balance: $5,000 APR: 24% Minimum payment: $125 (≈ 2.5% of balance) Extra: $0 Months to payoff: ≈ 65 Total paid: $8,125 Total interest: $3,125 The card costs more than 60% of the original purchases just in interest, and it takes more than 5 years. The same $125 paid for 5 years could be doing much more useful work elsewhere.
Same $5,000 balance at 24% APR, but paying $175/month total instead of $125. Months to payoff: ≈ 40 (vs 65) Total paid: $7,000 (vs $8,125) Total interest: $2,000 (vs $3,125) A $50/month bump cuts the payoff timeline by 25 months and saves $1,125 in interest. That's a 56% return on the extra effort.
Balance: $10,000 at 22% APR. Offer: 0% APR for 18 months on transfers, 3% transfer fee. Transfer cost: $300 upfront Required monthly to clear in 18 months: $10,300 / 18 ≈ $573 If you stayed on the original card paying $573/month: ≈ 21 months and ≈ $1,700 in interest. With transfer: 18 months and only $300 in fees. Net savings: ≈ $1,400. Balance transfers work only if you can pay off the balance before the promo expires, otherwise the post-promo rate (often higher than the original) eats the savings.
Use this calculator whenever you're carrying a credit card balance. It is the single highest-leverage piece of personal-finance math most people can do — credit card interest is uniquely punishing because it compounds monthly at rates that no responsible investment can outpace.
The rough financial-priority order for most U.S. households: 1. Pay enough on each card to avoid late fees and credit damage 2. Get the full 401(k) employer match (free money beats 22% APR) 3. Build a $1,000 starter emergency fund (so a flat tire doesn't add to credit debt) 4. Pay down credit card debt aggressively — usually before investing further 5. Build a full 3–6 month emergency fund 6. Invest for long-term goals
This calculator handles a single card with a fixed APR. If you have multiple cards, run it for each. If your APRs are floating or you have a promotional 0% period, run separate "phases" to model the change. For specific debt-payoff strategies across multiple debts, use the debt snowball or accelerated debt payoff calculators.
