Debt snowball vs. debt avalanche
| Avalanche | Snowball | |
|---|---|---|
| Pay extra on | Highest interest rate first | Smallest balance first |
| Saves the most interest | ✔ Yes | Sometimes close |
| Quick wins | Can take longer | ✔ First debt gone fast |
| Best for | Disciplined, math-first people | People who need motivation |
Both methods use the same total monthly payment. You pay the minimum on everything, put every extra dollar on one target debt, then roll that payment into the next debt once the first is gone. Try both in the calculator: if the difference in interest is small, pick the snowball for the motivation.
How much does paying extra help?
On a $5,000 credit card at 24% APR, a fixed $150 monthly payment takes about 4½ years and costs about $3,300 in interest. Paying $250 a month cuts that to just over 2 years and about $1,450 of interest. Small extra amounts make a big difference because card interest compounds every month.
Ways to speed it up
- 0% balance transfer card: usually 15–21 months at 0% for a 3–5% fee. It only helps if you pay it off before the promo ends.
- Call your card issuer and ask for a lower APR. It works more often than you’d think if you’ve paid on time.
- Debt consolidation loan: a personal loan at a lower fixed rate. Check the rate with our loan calculator.
- Stop adding new charges while you pay off. Use a debit card or cash for a while.

Credit Card & Debt Payoff Calculator FAQs
Is snowball or avalanche better?
Avalanche saves the most interest because you clear the most expensive debt first. Snowball can work better if quick wins keep you going. The calculator shows both with your real numbers.
How long will it take to pay off my credit card?
It depends on balance, APR and payment. Enter your card above with just the minimum payment, then add an extra amount to see how many months it saves.
What happens if I only pay the minimum?
Most of the payment goes to interest and it can take many years. Card minimums are often 1% of the balance plus interest, so the payment shrinks as you pay and the debt drags on.
Should I save or pay off debt first?
Most planners suggest a small emergency fund first (for example $1,000 or one month of expenses), then attack high-interest debt, because card APRs are usually far higher than savings rates.
