The avalanche method saves the most money; the snowball method keeps you motivated. On $30K of mixed debt, the avalanche saves $2,000–3,000 more in interest. But studies show snowball users are 14% more likely to actually eliminate all debt. The best method is the one you stick with. This calculator compares both strategies and shows your exact debt-free date.
Debt Avalanche Method
Pay highest-APR debt first while making minimums on the rest. When a debt is paid off, roll its minimum to the next highest-APR debt. Mathematically optimal — saves the most interest. Best for disciplined borrowers.
Debt Snowball Method
Pay smallest balances first for quick wins. When a debt is paid off, roll that payment to the next smallest. Journal of Consumer Research: snowball users are 14% more likely to eliminate all debt. Motivation matters.
Extra Payments Impact
Extra payments go directly to principal. $20K at 18% — adding $200 extra per month saves about $5,800 in interest and 3 years. Even $50–100 extra monthly can shave years off your timeline.
Debt-Free Date
The calculator simulates each month: interest accrues, then payments reduce principal. When total balance hits zero, that month is your debt-free date. Example: $25K CC at 22%, $600/mo → debt-free in ~60 months.
Payoff vs Investing
Compare debt APR to expected investment returns. If debt APR > expected return, prioritize payoff. $50K student loans at 5% vs investing at 10% — run the numbers; low-rate debt can sometimes be kept while investing.

Frequently Asked Questions
What is a debt payoff timeline?
A debt payoff timeline shows how many months it takes to become debt-free based on your balances, APRs, minimum payments, and extra payments. The calculator simulates month-by-month: interest accrues, then payments reduce principal. Avalanche vs snowball strategies produce different timelines. On $30K mixed debt, avalanche typically saves $2,000–3,000 more in interest.
What is the debt avalanche method?
The avalanche method targets the highest-APR debt first while paying minimums on the rest. When a debt is paid off, its minimum payment rolls to the next highest-APR debt. Mathematically optimal — saves the most interest. Best for disciplined borrowers motivated by numbers. On $30K ($12K@24% + $10K@19% + $8K@7%), avalanche saves $2–3K vs snowball.
What is the debt snowball method?
The snowball method pays smallest balances first for quick psychological wins. Pay minimums on all, put extra toward the smallest balance. When it's paid off, roll that payment to the next smallest. Studies show snowball users are 14% more likely to eliminate all debt — motivation matters. Best when interest rates are similar or you need early wins.
What is the impact of extra payments on debt payoff?
Extra payments go directly to principal, cutting payoff time and interest dramatically. Example: $20K at 18% — adding $200 extra per month saves about $5,800 in interest and 3 years off the timeline. Even $50–100 extra monthly can shave years. The best method is the one you stick with.
How is my debt-free date calculated?
The calculator simulates each month: interest accrues on remaining balances, then your payments reduce principal. When total balance hits zero, that month is your debt-free date. Extra payments accelerate the date. Example: $25K CC at 22%, $600/mo → debt-free in ~60 months.
Should I pay off debt or invest?
Compare your debt APR to expected investment returns. If debt APR > expected return (e.g., 5% student loans vs 10% market), prioritize payoff. If debt APR < expected return, investing may win mathematically — but debt payoff is guaranteed, investing is not. $50K student loans at 5% vs investing at 10%: run the numbers; low-rate debt can sometimes be kept while investing.
