Debt Payoff
Compare snowball and avalanche payoff order, timeline, and interest cost.
Your Debts
How much extra cash can you apply across all debts?

What this means
Minimum-only repayment can be slow and expensive. Extra payment consistency and APR targeting usually change the interest cost more than small differences in account count.
Scenario comparison
Cases to test next
| Case | Change | Watch |
|---|---|---|
| Current payment | Use today's minimums and extra payment. | Baseline payoff timing |
| Extra $100 | Add $100 to the monthly plan. | Months removed |
| Extra $250 | Add $250 if cash flow supports it. | Interest avoided |
| Lower APR | Model a refinance or balance transfer carefully. | Fees and expiration dates |

Debt payoff visual analysis
The chart and table should be read as a payoff model: no new charges, user-provided APRs, and steady extra payment.
| Signal | Value to watch | Why it matters |
|---|---|---|
| Balance over time | Debt curve | Projected total remaining balance by month. |
| Interest cost | Total interest | Modeled financing cost before all balances are gone. |
| Strategy order | Snowball or avalanche | Changes motivation and interest tradeoffs. |
| Extra payment | Cash flow lever | More monthly cash usually removes months from the plan. |

Snowball vs. Avalanche: Which Approach Wins?
Debt payoff is easier to plan when each balance, rate, minimum payment, and extra payment is visible. This calculator compares the debt snowball and debt avalanche methods. One prioritizes quick wins. The other prioritizes interest savings.
Worked example
Build the payoff plan before judging the strategy
The guide walks through a sample debt list, extra monthly payment, payoff order, and the assumptions that can move the timeline.

The debt snowball method pays debts in order from the smallest balance to the largest balance, regardless of interest rate. You keep paying the minimums on everything except the smallest debt, which receives the extra cash first.
Once that first small debt is gone, you roll its monthly payment into the next smallest debt. The benefit is motivational: a paid-off balance gives you proof that the plan is moving.
The Mathematical Superiority of the Debt Avalanche
The debt avalanche method lists debts from highest interest rate to lowest. The highest-rate balance receives the extra payment first, which usually lowers total interest when the assumptions hold.
The tradeoff is motivation. If the highest-rate debt is also the largest balance, the first payoff milestone may take longer. Compare both orders, then choose the plan you can keep using without adding new debt.
A hybrid payoff order
Some households use a hybrid order: clear one or two very small balances for simplicity, then switch to the highest-rate remaining debt. Model the interest cost before changing the order.
Frequently Asked Questions
Should I consolidate my debt?
Consolidation can lower your interest rates, but it doesn't "fix" the behavior that created the debt. Only consolidate if you are permanently committed to not using credit cards while paying off the loan.
What is "Good Debt" vs. "Bad Debt"?
Generally, "good debt" is an investment that grows in value or generates income over time (like a standard mortgage). "Bad debt" creates no long-term value and carries incredibly high interest (like consumer credit card debt).

Formula or calculation method
The calculator models debt payoff from each balance, APR, minimum payment, and extra monthly payment. It estimates monthly interest, applies required payments, targets one debt at a time, and displays a payoff timeline and total interest estimate.
Read the sitewide calculator methodology for how utility.finance documents formulas, assumptions, and model limits.
Plain-English assumptions
- Balances and APRs are treated as stable after you enter them.
- The extra payment is assumed to be available every month until payoff.
- The model does not add late fees, new purchases, promotional APR changes, or settlement discounts.
Worked example
Example: three cards totaling $10,000 at 19% to 27% APR with $300 in extra monthly cash may pay down much faster under avalanche than minimum payments alone, especially if the highest-rate card is attacked first.
Scenario comparison
Scenario comparison: minimum-only repayment can take years and produce high interest. Adding a fixed extra payment shortens the timeline. Avalanche targets rate efficiency while snowball targets balance momentum.
Sensitivity notes
Sensitivity note: payoff speed is most sensitive to APR, minimum payment size, and extra payment consistency. Missing one month matters less than returning to the plan quickly.
Common mistakes
- Looking only at total balance and ignoring APR differences.
- Treating a balance transfer as savings without including the transfer fee and expiration date.
- Closing every paid-off account without considering credit utilization and account-age effects.
FAQ
What if my minimum payment changes?
Update the minimum payment and recalculate. Credit card minimums often decline as balances fall, but keeping the old payment amount can speed up payoff.
Should I save or pay debt first?
Many households keep a small cash buffer before attacking high-rate debt. The right balance depends on income stability and the cost of the debt.
