Debt Payoff Calculator

Avalanche (highest APR first) minimizes total interest and is mathematically optimal — with $48,000 across credit card (22.99%), car (6.5%), and student loan (5%), avalanche typically saves $1,000–3,000 more than snowball with $300/month extra. Snowball (smallest balance first) gives quicker wins and helps some people stay motivated. Use this calculator to compare both with your actual debts.

It depends on your balances, APRs, and extra payment. With $48,000 in total debt and $300/month extra, both avalanche and snowball save thousands in interest and cut years off your debt-free date compared to minimum payments only. High-APR debt (e.g. credit cards at 22–24%) costs the most — targeting it first with extra payments usually saves the most. Enter your debts in the calculator to see exact interest saved.

For the lowest total interest: pay minimums on all debts and put every extra dollar toward the debt with the highest APR (avalanche). For psychological momentum: pay off the smallest balance first, then roll that payment to the next (snowball). This calculator shows the exact order for both strategies and the interest difference so you can choose.

A $10,000 balance at 22.99% APR with a $250 minimum and $300 extra ($550 total) can be paid off in roughly 2–3 years instead of 5+ with minimum only — saving thousands in interest. Exact time depends on your balance, rate, minimum, and extra amount. Add your card to the calculator to see your debt-free date and total interest.

Yes. Snowball works by freeing up minimum payments as each debt is eliminated and applying that cash to the next debt, creating a cascading effect. It often pays off debt faster than minimum-only by hundreds or thousands of dollars. Avalanche usually saves slightly more in interest, but both strategies are far better than paying only minimums. Run your numbers in the calculator to see the difference.

With $30,000 spread across cards and loans, avalanche usually saves more interest because it targets the highest APR first. In many scenarios, interest savings are around $1,000 to $3,000 compared with snowball when monthly payment is the same. Snowball can still be useful if fast early wins improve consistency.

For a $40,000 debt stack near a 10% blended APR, adding $300 per month can shorten payoff by about 3 to 5 years. It can also cut total interest by roughly $8,000 to $15,000. Exact results depend on minimum payments, APRs, and payoff strategy.

At 22% APR with a fixed $300 monthly payment, $10,000 is paid off in about 47 months. Total interest paid is roughly $4,000 over that period. Increasing payment to $400 can cut the timeline to about 32 months and reduce interest by around $1,600.

Debt consolidation saves money only if the new APR and fees are lower than your current weighted cost. For example, moving $20,000 from 19% to 10% APR can reduce annual interest from about $3,800 to $2,000 before fees. If origination fees are 5%, that is a $1,000 upfront cost you must offset with rate savings.

Use snowball if psychological wins matter more than marginal interest savings. If quitting feels likely with avalanche (no visible progress for months), snowball can improve adherence. The interest gap is often $1,000–$4,000 on $30K–$50K debt — if snowball keeps you paying consistently, it can be worth it.

If your debt APR is higher than expected after-tax investment returns (e.g. 20% credit card vs 7% market), pay debt first. High-interest debt is a guaranteed loss. For low-rate debt (e.g. 4% student loan), investing may yield more long term, but eliminating debt reduces risk and frees cash flow.

No. Paying off debt typically improves your credit utilization and payment history, which can raise your score. Closing an account may cause a brief dip, but being debt-free and having lower utilization usually benefits your score over time.

Enter each debt (balance, APR, minimum payment) and your extra monthly payment in this calculator. It runs month-by-month until all balances reach zero and shows your debt-free date for both avalanche and snowball. Adjust the extra payment to see how it changes.
