How to use this tool
- List each debt with its balance, interest rate (APR), and minimum monthly payment.
- Enter how much extra you can put toward debt each month, beyond the minimums.
- Compare the avalanche and snowball results side by side — payoff time, total interest, and the order each debt clears.
Common mistakes to avoid
- This assumes you keep paying every minimum plus the extra amount consistently — missing a payment or reducing the extra amount changes the real timeline.
Frequently asked questions
- What's the difference between avalanche and snowball?
- Avalanche pays off the highest-interest-rate debt first, which mathematically minimizes the total interest you pay. Snowball pays off the smallest balance first, so you clear an individual debt faster — a psychological win that some people find easier to stick with, even though it usually costs more in total interest.
- How is the extra payment applied?
- Every debt gets at least its minimum payment each month. Your extra amount goes entirely toward whichever debt is highest-priority under the chosen strategy. Once a debt is paid off, its minimum payment amount rolls into the extra pool for the next debt — the payment "snowballs" as debts clear.
- Why do avalanche and snowball show different total interest for the same debts?
- Because the order debts get paid off in changes how long each balance sits accruing interest. Avalanche always results in equal or lower total interest than snowball for the same extra payment amount — the tradeoff is purely about interest cost versus which strategy is easier to stay motivated with.
- Is my debt information uploaded anywhere?
- No — the simulation runs entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — simulated in this tab | Yes, uploaded to process |
| Compares both strategies side by side | Yes | Varies — many tools only support one strategy |
| Account required | Never | Often, past a certain usage level |
