Credit card debt at 20%+ interest grows faster than almost any investment, which makes paying it off the highest-return move most people can make with their money. Yet minimum payments — often just 1–2% of the balance — are structured to stretch repayment over decades while interest quietly multiplies the original debt several times over. This calculator shows the honest math: enter your balance, APR and monthly payment to get your exact payoff date and total interest, then compare the minimum-payment path against a fixed higher payment. The difference is usually shocking enough to change behavior: a modest extra amount each month routinely cuts years off the timeline and saves thousands.
Why minimum payments are a trap
On a $8,000 balance at 24% APR with a 2% minimum payment, you would pay for over 30 years and hand over more than $22,000 in interest — nearly triple the original debt. The minimum shrinks as the balance shrinks, so progress slows exactly when you need it to accelerate.
Example
$8,000 at 24% APR. Minimum payments (~$160 initially): 30+ years, ~$22,000 interest. Fixed $300/month: paid off in about 3 years, ~$3,300 interest. Same debt — $18,700 less interest.
Payoff strategies
Avalanche (highest APR first) costs the least in interest. Snowball (smallest balance first) wins psychologically with quick victories. Both beat minimums by miles. A balance-transfer card at 0% for 12–21 months can accelerate either strategy — just watch the transfer fee (typically 3–5%).
Frequently asked questions
How long will it take to pay off my credit card?
It depends on balance, APR and payment. Enter your numbers above — with minimum payments it is often decades; with a fixed payment it is usually 2–5 years.
Should I pay the highest APR card first?
Mathematically yes — the avalanche method minimizes total interest. If you need motivation, the snowball method (smallest balance first) works better for some people.
Does a balance transfer make sense?
Often, if you get 0% for 12–21 months and can pay the balance off in that window. Factor in the 3–5% transfer fee and have a plan for the remaining balance.
Will paying off cards help my credit score?
Yes — lower utilization (balance ÷ limit) is a major scoring factor. Paying cards down is one of the fastest ways to lift a score.
