How this is calculated
Debts are ordered by strategy (snowball by balance, avalanche by APR, or hybrid) and simulated month-by-month: interest accrues, payment applies, balances drop until zero.
Extra payment fields shift all downstream months immediately so you can see marginal value of $50 more.
Use this tool for
- Choosing between avalanche and snowball when balances are similar but motivation differs.
- Modeling a lump-sum bonus applied to the highest APR card first.
- Showing a partner how long minimum payments really take.
Common questions
Why might Debt Payoff Calculator differ slightly from my bank or payroll system?
Rounding, proration rules, or local taxes vary by processor. Treat this page as a sanity check, then trust the official system of record for exact cents.
Does Debt Payoff Calculator work offline after it loads?
Usually yes—the math is client-side. You still need an initial load of assets; avoid hard-refreshing on captive portals if you need the page without network.
