      What If You Paid More?

      See how adding extra to your monthly payment changes your debt-free date and total interest, using the debts entered above (Avalanche shown).

      Worked Example: $16,000 Across 3 Debts

      Someone carries three debts totaling $16,000: two credit cards at 18.99% and 22.99%, and a personal loan at 12.5%. Minimum payments total $440/month, and they can add $200/month extra.

      With Snowball, they attack the smallest balance first and are debt-free in 2 years 7 months, paying $3,375 in total interest.

      With Avalanche, they attack the highest rate first and are debt-free in 2 years 7 months, paying $3,375 in total interest — essentially the same cost as Snowball here.

      Because the gap between the two methods is small in this example, this visualizer's default recommendation leans toward Snowball — but the right call always depends on whether you personally need the early-win motivation snowball provides.

      How to Compare Debt Snowball and Debt Avalanche Payoff Plans

      Step-by-step method to see your exact debt-free date under both the snowball and avalanche repayment strategies.

      1. 1. Add your debts: Enter the name, balance, interest rate, and minimum payment for each debt you are carrying.
      2. 2. Set your extra payment: Enter any extra amount you can put toward debt each month beyond the minimums.
      3. 3. Compare the strategies: Review months to debt-free, total interest paid, and payoff order for both snowball and avalanche.
      4. 4. Pick your plan: Choose the method that fits your situation — avalanche to minimize interest, or snowball for faster early wins.

      Snowball vs. Avalanche: What's the Real Difference?

      Debt Snowball targets your smallest balance first, no matter what it costs you in interest. Every debt you fully pay off is one less monthly payment to juggle, and that early win is the whole point — it's a behavioral strategy as much as a financial one.

      Debt Avalanche targets your highest interest rate first. It's the mathematically optimal order — every dollar of extra payment is working against the debt that's costing you the most — so it minimizes total interest paid across every debt you're carrying.

      Neither method changes your minimum payments or your total monthly commitment — they only change the order extra money gets applied. That's why this visualizer runs both simulations side by side: the numbers make the trade-off concrete instead of theoretical.

      How the Simulation Works

      • Each month, interest accrues on every open balance at rate ÷ 12.
      • Minimum payments are made on every debt that still has a balance.
      • Your extra payment, plus the minimum payments freed up from any debt already at $0, all go to a single target debt.
      • Snowball target = smallest remaining balance. Avalanche target = highest remaining interest rate.
      • This repeats month over month until every balance reaches $0 — that month is your debt-free date.

      Frequently Asked Questions

      Q: What is the difference between the debt snowball and debt avalanche methods?

      The snowball method pays off the smallest balance first regardless of interest rate, then rolls that payment into the next-smallest balance. The avalanche method pays off the highest interest rate first. Avalanche is mathematically optimal — it minimizes total interest — while snowball tends to build momentum faster through early wins.

      Q: Which method saves more money?

      Avalanche almost always saves more in total interest, since it eliminates your most expensive debt first. The gap is usually small when your balances and rates are similar, and larger when one debt carries a much higher rate than the others.

      Q: Why would I choose snowball if it costs more?

      Research on behavior change suggests quick, visible wins keep people motivated to stay on a payoff plan. If a slower first win with avalanche means you are more likely to quit partway through, snowball's early payoff can be worth the extra interest in practice.

      Q: How is the payoff order calculated?

      Each month, minimum payments are made on every debt, then any extra payment — plus the freed-up minimum payments from already-paid-off debts — is applied to a single target debt: the smallest balance for snowball, or the highest rate for avalanche. Once that debt hits zero, the next one in line becomes the target.

      Q: Does this calculator account for interest compounding monthly?

      Yes. Interest accrues on each debt's balance every month at rate ÷ 12, before that month's payments are applied — matching how most credit cards and personal loans compute interest.

      Q: What if I only pay the minimums?

      Set your extra monthly payment to 0 to see how long payoff takes and how much interest you pay with minimums alone. For high-rate debt like credit cards, this is often dramatically slower and more expensive than adding even a small extra payment.

      Q: Can I add more than three debts?

      Yes — use "Add Another Debt" to add as many as you need. The simulation recalculates the full payoff schedule for every debt you add.

      Q: Does this work in currencies other than US dollars?

      Yes. Balances, minimum payments, and extra payments can all be entered and displayed in US Dollar, Euro, British Pound, Indian Rupee, Australian Dollar, Canadian Dollar, Japanese Yen, UAE Dirham, or Singapore Dollar. Months to debt-free and interest-rate math are currency-independent, so the comparison stays valid regardless of which currency you pick.
