Avalanche attacks the highest APR first and minimizes lifetime interest, while snowball clears the smallest balance first for momentum. Example: $5,000 at 24% minimum $150 and $2,000 at 18% with $200 extra finishes months sooner under avalanche and saves noticeable interest.
The simulator pools all minimums and your extra payment into one fixed monthly amount, then rolls each freed minimum into the next priority debt. Example: $150 and $80 minimums and $200 extra creates a $430 pool that cascades automatically until every balance reaches zero.
No, this debt-payoff comparison is for informational planning only, not financial advice. Penalty APRs, balance-transfer fees, credit-score effects and variable rates are excluded from the $5,000 at 24% illustration. Consult a qualified professional about personal choices and see /terms before changing payments.
Yes. Payoff debt math stays on this phone only. Balance APR sums run in-tab offline with no server send and no login. For example, $5,000 stays local, runs net-off, and wipes on close. Planning only, not advice. See /terms for details.
Because minimums barely cover 2% monthly accrual, $5,000 at 24% accrues $100 monthly, leaving $50 principal from $150, while $300 extra directs $350 to principal, collapsing 60-month slog to 22 months. Interest plunges $3,200 toward $1,100. Model $150 versus $450 pools here. See /terms.
Consolidation suits disciplined borrowers, swapping $7,000 at 24%/18% blended near 22% for 12% three-year $231 monthly, saving $1,800 interest and fixing end date. Spendthrifts refilling cards double debt. Compare transfer 3% fee versus origination 2% here. Credit strategy only, not lending counsel. See /terms.
Snowball eradicates the tiniest balance first for psychological victories, while avalanche targets the loftiest APR first for mathematical thrift. A $5,000 card at 24% minimum $150 and $2,000 at 18% minimum $80 with $200 extra illustrates divergence: avalanche clears 24% first, saving about $320 versus snowball. Outcome table: | Method $7k $200 extra | Payoff order | Total interest | Avalanche | 24% then 18% | $1,450 | Snowball | $2k then 24% | $1,770 | Minimums only | Pro-rata | $3,200 |. Quick wins cost $320 premium. Our debt payoff calculator simulates both sequences with months, interest, and freedom date privately offline. Edge case: 0% balance-transfer promos with 3% fee temporarily outrank avalanche logic. Limitation: ignores penalty APR spikes, utilisation scoring, and variable resets. Prioritize emergency cushions via /salary-calculator. Behavioral maths only, not credit advice. See /terms.
The engine aggregates every minimum and your supplemental contribution into a fixed monthly war chest, then avalanches freed installments into the next priority balance upon clearance. For example, $150 and $80 minimums and $200 extra forms a $430 pool; when $2,000 at 18% vanishes in 6 months, $430 attacks $5,000 at 24%. Escalation table proves leverage: | Monthly pool $7k debts | Debt-free | Interest | $330 ($100 extra) | 34mo | $2,100 | $430 ($200 extra) | 28mo | $1,450 | $530 ($300 extra) | 22mo | $1,100 |. Hundred extra shaves six months. Edge case: deferred-interest retail cards retroactively bill 29.99% if $1,200 balance lingers past promo midnight. Limitation: presumes no fresh spending, static APRs, and fee-free prepayments. Model housing tradeoffs via /rent-vs-buy-calculator. Simulation logic only, never personal debt counsel. See /terms.
Add $5,000 at 24% minimum $150 and $2,000 at 18% minimum $80 with $200 extra to compare 28-month avalanche at $1,450 interest versus 29-month snowball at $1,770, then boost to $300 extra to hit 22 months and $1,100. Duel table crystallizes choice: | Scenario | Months | Interest | Avalanche $200 | 28 | $1,450 | Snowball $200 | 29 | $1,770 | Avalanche $300 | 22 | $1,100 |. Avalanche saves $320 for identical cash. Edge case: job loss forcing minimums-only reverts timeline to 60 months and $3,200 interest, demanding buffer funds. Limitation: excludes transfer levies, late penalties, score impacts, and rate variability detailed beside payoff schedules. Explore true loan cost via /emi-calculator.
