Credit Card Payoff Calculator
Plan how fast you can eliminate credit card debt. Add one or multiple cards, choose Snowball or Avalanche, and see an estimated debt-free date plus total interest — then adjust extra payments to speed things up.
What this credit card payoff calculator estimates
This page helps you answer three practical questions:
- How long until I’m debt-free? (months + years)
- How much interest will I pay? (estimated total)
- Which strategy is better for me? (Snowball vs Avalanche)
Add multiple credit cards, enter balance, APR and minimum payment, then test how an extra monthly payment changes the payoff timeline.
Snowball vs Avalanche: quick comparison
| If your goal is… | Pick Snowball | Pick Avalanche |
|---|---|---|
| Staying motivated with quick wins | ✅ Often best | ➖ Can feel slower at first |
| Minimizing total interest paid | ➖ Not optimal | ✅ Usually best |
| Reducing the highest APR risk ASAP | ➖ Not targeted | ✅ Targeted (highest APR first) |
| Simplest mental model | ✅ Very simple | ✅ Also simple |
How credit card interest works (APR explained)
Most credit cards advertise an APR (annual percentage rate). A simple monthly approximation is: monthly rate ≈ APR / 12. If you carry a balance, interest accrues on the remaining balance and compounds over time.
Example: a $5,000 balance at 24% APR has a rough first-month interest cost of: $5,000 × 0.24 / 12 = $100. Paying more than the minimum reduces the balance sooner, so you pay less interest overall.
Note: many issuers use average daily balance and daily compounding. This calculator simplifies the mechanics so you can compare strategies and estimate impact.
The minimum payment trap (and how to escape it)
Minimum payments are designed to keep accounts current, not to eliminate debt quickly. If your minimum is close to (or even below) your monthly interest, your balance can shrink very slowly.
- Raise your payment: even +$25–$100/month can cut months or years.
- Lower the APR: negotiation, refinance, or a balance transfer can reduce interest drag.
- Stop new charges: new purchases can undo the progress you’re modeling.
A practical payoff checklist (10 minutes to a plan)
- List every card (balance, APR, minimum).
- Pick a strategy: Avalanche (math) or Snowball (momentum).
- Choose an extra payment you can sustain monthly.
- Run scenarios: try +$50, +$100, +$200 and compare interest saved.
- Automate payments around paycheck dates to avoid late fees.
- Review monthly: as balances drop, re-run the plan.
Common mistakes that slow down payoff
- Only paying minimums while carrying high APR balances.
- Ignoring fees (annual fees, late fees, balance transfer fees).
- Switching strategies too often — pick one and stick to it for a few months.
- Leaving high-APR debt unattended while focusing only on balance size.
- Not tracking utilization if you also care about credit score improvements.
