Debt Snowball Planner

How the math works

• Your monthly budget is fixed at the first month's minimums plus your extra amount. When a debt is paid off, its payment stays in the budget and rolls to the next debt. “Minimums only” has no extra and no rollover.
• Snowball pays the smallest starting balance first. Avalanche pays the highest APR first.
• Credit card minimums are the larger of the floor or (percent of balance + that month's interest), so they shrink as the balance drops.
• Federal student loans use simple interest: interest accrues separately and never earns interest itself. Payments go to accrued interest first.
• Income-driven payments are recalculated every 12 months from your AGI and income growth. IBR uses income above 150% of the 2025 HHS poverty guideline ($15,650 + $5,500 per extra person) and is capped at the 10-year standard payment. RAP uses 1–10% of AGI by $10k bracket, minus $50 per dependent, with a $10 minimum. Unpaid interest is waived and principal is matched up to $50. Check your exact numbers at studentaid.gov.
• Forgiven IDR balances may count as taxable income. This planner does not estimate that tax.
• Fixed rates, no new charges, payments on the 1st of each month. Projections stop at 50 years.
