How Long Will It Take to Pay Off My Credit Card? (Exact Math by Balance)

The 'how long?' question has only three inputs: how much you owe, the APR, and how much you can pay each month. Plug those into the standard amortization formula and you get the answer in seconds. The numbers below assume a constant monthly payment (which beats the shrinking minimum payment every time).

$1,000 balance at 22% APR

• $50/month: ~24 months, ~$240 interest
• $100/month: ~11 months, ~$110 interest
• $200/month: ~6 months, ~$55 interest

$3,000 balance at 22% APR

• $100/month: ~46 months, ~$1,560 interest
• $200/month: ~18 months, ~$580 interest
• $400/month: ~9 months, ~$280 interest

$5,000 balance at 22% APR

• $150/month: ~57 months, ~$3,500 interest
• $300/month: ~21 months, ~$1,200 interest
• $500/month: ~12 months, ~$640 interest

$10,000 balance at 22% APR

• $250/month: ~73 months, ~$8,150 interest
• $500/month: ~26 months, ~$2,940 interest
• $800/month: ~15 months, ~$1,700 interest

What changes the math fastest

Reducing APR (via balance transfer or rate negotiation) compounds with every dollar of remaining balance. Raising monthly payment compounds the speed of principal reduction. Lowering balance immediately (with a tax refund or bonus) cuts both interest and time. The calculator lets you stack all three changes to see the combined impact.

Use a calculator instead of a table

Tables like these are useful for orientation. For your actual numbers — including multiple cards at different APRs — run the calculator. It produces the exact payoff date, total interest, and per-card breakdown that no static table can match.
