Your Debts
| Name | Balance | Interest Rate | Min Payment | |
|---|---|---|---|---|

⛄ Snowball Method
Pay smallest balance first (quick wins)

Scenario guide
Compare avalanche and snowball with a constant monthly portfolio budget.
Method and posting
Each month accrues APR ÷ 12 interest, pays active minimums, then directs remaining budget in strategy order. Unused minimums and cleared-debt minimums roll over. Zero-opening debts create no budget. Dates use a captured calculation date and clamp to the last day of the target month.
Amounts post to two decimal places. Totals use the posted amounts; final loan payments can differ from the regular payment. Use the same currency for every input. A display currency or language does not select a jurisdiction. Rounding ties are away from zero; input amounts round from their decimal representation.
Arithmetic example
100 ÷ 10 = 10; 0% → 100.
Assumptions and limits
Avalanche prioritizes highest APR; snowball prioritizes smallest opening balance. A demonstrated non-decreasing state is never paid off under these assumptions; other unresolved simulations stop at 1200 months with a residual and no payoff date. Fees, changing rates and changing minimum rules are excluded.

Frequently Asked Questions
Yes. Any amount left after clearing a target continues to the next debt.
A residual at the cap or a non-amortizing fixed state is not a completed payoff.
