How to use Debt Payoff Planner

  2. Enter the total monthly repayment budget.
  3. Compare payoff time, modeled interest and the exported schedules.

Example: Debt Payoff Planner

Debt Payoff Planner: Snowball: paid off; avalanche: paid off.

You add
Debts, one per line: One 100 0 10 Total monthly payment budget: 20
You get
Snowball: paid off; avalanche: paid off. Measure Value Snowball status paid off Snowball last month checked 5 Snowball interest 0.00 Snowball payments 100.00 Snowball: One payoff month / remaining balance 5 / 0.00 Avalanche status paid off Avalanche last month checked 5 Avalanche interest 0.00 Avalanche payments 100.00 Avalanche: One payoff month / remaining balance 5 / 0.00 Monthly interest = opening balance × entered nominal APR / 12, rounded half up to cents. Minimum payments come first; remaining budget cascades to the smallest opening balance (snowball) or highest APR (avalanche). Ties use input order. No new purchases, fees, variable rates or lender-specific rules. A 1200-mon Snowball status | paid off Snowball last month checked | 5 Snowball interest | 0.00

Compare orders using the same payment assumptions

The model charges monthly interest before payments and rounds interest to cents. A cleared debt releases its share of the common budget to the remaining debts. Actual minimums, fees and rate changes can differ; an unfinished schedule or insufficient budget is a result to investigate, not a predicted payoff date.

Questions about Debt Payoff Planner

What distinguishes the two orders?

Snowball targets the smallest opening balance; avalanche targets the highest entered rate. Both cover fixed minimums first. Ties keep the input order.

Can I compare different budgets?

Each run uses the same budget for both strategies so their repayment order is the difference. Change the budget and run another comparison.

Does this match a lender’s statement?

Not necessarily. Daily interest, changing rates, fees and real minimum-payment rules can differ from this monthly model.
