Credit Cards Payoff Calculator
Adjust the inputs below. Results update as you type.
How it works
Avalanche: pay minimums on all cards, put extra toward highest-APR card first—mathematically optimal. Snowball: pay off smallest balance first for motivation. Enter each card's balance, APR, and minimum payment. The total minimum payments set your floor; any extra accelerates payoff. Consolidation loans can lower the blended rate but extend the term—compare total interest.
Input guidance
- Use realistic rates from lender or provider quotes instead of headline averages.
- Model conservative, baseline, and optimistic scenarios before deciding.
- Include recurring real-world costs (fees, taxes, insurance, maintenance) where relevant.
The formula
With multiple cards, total payoff time depends on your strategy: the avalanche method targets the highest APR first to minimize interest; the snowball method targets the smallest balance first for motivation.
Worked example
Paying $600/month across three cards totaling $12,000, the avalanche method (highest rate first) typically saves the most interest, while the snowball clears individual cards sooner for quick wins.
More examples to test
- Conservative case: use a higher interest rate and lower growth assumptions to stress-test affordability.
- Optimistic case: use a lower rate with stable income assumptions to compare upside potential.
How to interpret results
Treat this as a planning model, not a final approval tool. Compare at least two scenarios and focus on total-cost and cash-flow trade-offs.
When this can be inaccurate
Results can diverge due to fees, changing rates, tax rules, lender policies, and behavior changes that simplified models cannot fully capture.

Frequently asked questions
Avalanche or snowball?+
Avalanche saves the most money by killing the highest interest first. Snowball clears small balances fast for psychological wins. Both work if you stay consistent.
Should I consolidate instead?+
A lower-rate consolidation loan or balance transfer can cut interest, but only helps if you stop adding new debt and pay it down on schedule.
Pay one card or spread payments?+
Always pay every minimum, then put all extra money on a single target card. Spreading extra thinly slows total payoff.
How should I use this result?+
Treat it as a planning estimate. Compare at least two realistic scenarios, then confirm with statements, quotes, or a qualified professional before acting.
How often should I refresh assumptions?+
Refresh whenever rates, income, costs, or policy limits change materially, and before making irreversible commitments.
