A real example: $8,000 of credit card debt
Say you owe $8,000 on a credit card at 22% APR. Paying $250 a month, you'd be debt-free in about 4 years and pay roughly $4,150 in interest.
Bump that to $400 a month and it changes dramatically: paid off in about 25 months — over two years sooner — with total interest of only about $2,050. That's $2,100 saved just by paying more each month. Enter your balance, rate and payment above to see your own payoff date.
Why paying off debt is one of the best "investments"
Paying off a credit card charging 22% APR is the equivalent of earning a guaranteed, tax-free 22% return — far more than you can reliably earn investing. That's why clearing high-interest debt is almost always the first step toward financial freedom.
Snowball vs avalanche
- Avalanche: pay extra toward the highest interest rate debt first. Mathematically cheapest.
- Snowball: pay off the smallest balance first for quick psychological wins. Often more motivating.
Both work — the best method is the one you'll actually stick with. This calculator shows a single debt; apply extra payments to one debt at a time while paying the minimum on the rest.
Ways to pay down debt faster
Balance transfer cards
Moving high-interest balances to a 0% intro card can pause interest while you pay down principal.
Compare cards →Debt consolidation loan
A lower fixed-rate personal loan can simplify payments and cut interest.

What if my payment barely covers the interest?
If your monthly payment is less than the interest charged, the balance never shrinks. You must pay more than the monthly interest to make progress — the calculator will warn you if so.
Should I save or pay off debt first?
Keep a small emergency fund, then attack any debt with an interest rate higher than you could reasonably earn investing (generally anything above ~6–8%).
