Should I use a 0% balance transfer card?

If you can clear the balance during the 0% period (usually 12–21 months) — yes, and factor in the 3–5% transfer fee. If not, you're back to high-interest at the end.

Is paying off the card better than investing?

Almost always. Stock market averages ~10%/year long-term; card APR is 20%+. Paying down debt is a guaranteed 20%+ return.

About this tool

Credit card debt is among the most expensive consumer debt — APRs of 20–28% are common. This calculator shows the brutal math: how long it takes to clear a balance at a fixed monthly payment and how much you give up in interest. Try lowering the payment to see when the math breaks (your payment can't even cover the interest, so the balance grows forever). Then nudge the payment up — even an extra $50/month often shaves years off and saves thousands.

Frequently asked

Card minimums (often 1–2% of balance) are barely above the interest charge. Pay only the minimum and a $5,000 balance can take 20+ years to clear and cost $10,000+ in interest.
