Result summary
Quick answer
With the sample inputs, this calculator returns Avalanche saves $50.92 with the same payoff time. Snowball payoff order: Debt 3 → Debt 1 → Debt 2. Use Avalanche saves $50.92 with the same payoff time as the comparison under one fixed monthly debt budget, then confirm every required minimum and update the payoff order when balances or rates change.

How to use this calculator
Open the short walkthrough for choosing and checking inputs.
Each month the calculator rounds interest to cents on every active debt, applies each entered planned payment, and sends the remaining shared budget to the current strategy target. Snowball targets the smallest remaining balance; avalanche targets the highest APR.

Calculation details
Formula and methodology
See the exact math used to produce the result.
Both payoff paths keep one fixed monthly budget: snowball sends remaining money to the smallest balance, while avalanche sends it to the highest APR after planned payments are made.
Before acting
Assumptions to check
Review the real-world details that can change the estimate.
The key inputs are separate balances, APRs, planned payments, and one extra amount. The total monthly budget stays fixed after payoff, interest rounds monthly to cents, and unused final-payment money moves to the next target in the same modeled cycle.

When to round up
The model immediately redirects unused same-month money when a debt is paid. It assumes fixed APRs, fixed planned payments, no new charges or fees, and monthly interest; real required minimums, daily interest, payment allocation, and variable rates can differ.
When to use this calculator
- Comparing smallest-balance-first with highest-APR-first payoff
- Keeping one monthly debt budget constant after each payoff
- Seeing how payoff order changes modeled interest and timing
Tips for better estimates
- Enter each balance, APR, and planned minimum separately.
- Keep the same total monthly debt budget in both comparisons.
- Recheck the order when balances, required minimums, rates, or available extra payment change.
How this calculator is reviewed
This page is checked for inputs, formulas, examples, assumptions, topic fit, and related links. For this calculator, the review also covers separate balances, APRs and planned payments, fixed total debt budget, snowball and avalanche target order, cents-rounded interest, same-cycle rollover, changing minimums, and issuer posting differences.
The sample result is covered by automated tests, and the page links to related calculators and, where available, supporting guides so readers can check the assumptions before acting. If a formula, label, or assumption looks off, send the page URL and your inputs through the contact page.
How this estimate was built
This page models separate debts under one fixed monthly budget, applies monthly interest and planned payments, then redirects the remaining budget to the current snowball or avalanche target, including same-cycle final-payment rollover.
Worked example
Example inputs: Debt 1 balance: $1000; Debt 1 APR: 24 %; Debt 1 planned payment: $50 /month; Debt 2 balance: $3000; Debt 2 APR: 18 %; Debt 2 planned payment: $90 /month; Debt 3 balance: $500; Debt 3 APR: 10 %; Debt 3 planned payment: $25 /month; Debt 4 balance: $0; Debt 4 APR: 0 %; Debt 4 planned payment: $0 /month; Extra monthly debt payment: $100 /month. With those values, the calculator returns Avalanche saves $50.92 with the same payoff time. Under the same $265.00 monthly budget, snowball estimates $764.37 of interest over 20 months and avalanche estimates $713.45 over 20 months.
Example scenarios
- For balances of $1,000 at 24%, $3,000 at 18%, and $500 at 10%, planned payments of $50, $90, and $25 plus $100 extra create a fixed $265 monthly budget.
- The snowball order is Debt 3, Debt 1, then Debt 2 and estimates $764.37 of interest over 20 months.
- The avalanche order is Debt 1, Debt 2, then Debt 3 and estimates $713.45 of interest over the same 20 months, or $50.92 less modeled interest.
Quick reference chart
| Sample result | Avalanche saves $50.92 with the same payoff time |
|---|---|
| Snowball payoff order | Debt 3 → Debt 1 → Debt 2 |
| Avalanche payoff order | Debt 1 → Debt 2 → Debt 3 |
| Snowball total paid | $5,264.37 |
| Avalanche total paid | $5,213.45 |
| Best next step | Choose a payoff order only after confirming every required minimum and keeping the fixed total payment budget affordable. Recheck the plan when balances, rates, or minimums change. |
FAQs
Debt Snowball vs Avalanche Calculator questions
What is the debt snowball method?
It keeps planned payments on all debts and directs extra money to the smallest remaining balance, then rolls that money to the next smallest balance.
What is the debt avalanche method?
It keeps planned payments on all debts and directs extra money to the highest-APR balance, then moves to the next-highest APR.
Does avalanche always finish sooner?
Not necessarily in every rounded payment schedule, although targeting higher APR debt often lowers modeled interest. The calculator shows both outcomes under the same budget.
Are the entered payments future required minimums?
No. They are fixed planned payment assumptions. Card and loan minimums can change as balances fall, so confirm current requirements and keep every account current.

Common planning mistakes
Reducing the total debt budget after an account is paid, entering changing minimum payments as though they stay fixed, combining debts with different APRs, and assuming modeled payoff order matches issuer posting dates.
