Debt Payoff Planning Guide
Strategy Basics
A debt payoff plan works best when every payment has a job. This calculator compares two common methods. The debt snowball pays the smallest balance first. The debt avalanche pays the highest interest rate first. Both approaches use minimum payments on every debt. Extra money then goes to one target debt.
The snowball method can feel motivating. It creates faster wins on small accounts. Those wins may help users stay consistent. The avalanche method is usually cheaper. It attacks expensive interest first. That often reduces total interest and time.
Why the Comparison Matters
This tool helps compare both paths together. Enter each account name, balance, rate, and minimum payment. Add any extra monthly amount you can afford. Add a starting lump sum when available. The calculator builds monthly projections for both strategies. It shows payoff months, interest cost, payment totals, and payoff order.
Reading the Schedule
The calculation uses monthly compounding. Each month starts with the remaining balance. Interest is added using the yearly rate divided by twelve. Minimum payments are applied to active debts. Any unused money rolls into the target debt. When one debt is cleared, its old payment becomes available for the next debt.
A lower interest total means better mathematical savings. A shorter timeline means faster freedom. A different first payoff may mean stronger motivation. The best method depends on behavior and cost. Some users choose avalanche for savings. Others choose snowball for momentum. Many users start with snowball, then switch later.
Planning Tips
Check whether minimum payments are realistic. Increase the extra payment to test faster payoff dates. Reduce it if the plan feels too tight. A sustainable amount is better than a plan you abandon. Always keep emergency cash available. Avoid adding new balances during the payoff plan. New debt can erase progress quickly.
Exports and Updates
Use the CSV export for spreadsheet review. Use the PDF export for sharing or saving. Revisit the calculator after rate changes, balance transfers, bonuses, or budget updates. Small monthly increases can make large differences. Even a modest extra amount may remove months from repayment. That insight supports better budget choices over time. A debt plan should change when real life changes.
