How to use Multi-debt Payoff Strategy Comparison

Monthly interest is nominal entered APR divided by 12. Pay each capped fixed minimum, then allocate the unused budget by the declared priority; source order resolves ties. Each month retains a balance-conservation witness.

  1. Use the example as the schema; replace its labels and entered model assumptions.
  2. Monthly interest is nominal entered APR divided by 12. Pay each capped fixed minimum, then allocate the unused budget by the declared priority; source order resolves ties. Each month retains a balance-conservation witness.
  3. Calculate, inspect the complete witnesses and limitations, then copy or download the JSON report.

Good to know

  • 1–20 named debts, 1–1,200 months; money amounts have whole cents and are at most 1,000,000,000 each. APR strings range from 0% through 1,000%. Simulated balances are capped at 10,000,000,000,000.00.
  • Use fixed user assumptions only. No daily accrual, changing rates, new borrowing, lender minimum formula, live quote, legal APR or financial advice. A budget error or unresolved horizon is not a payoff.
  • Local calculation with no upload, input persistence or outside lookup. Model JSON is limited to 30,000 characters and 10,000 values. Decimal quantities are strings with up to six places; count fields use plain JSON integers. Exact fractions are capped at 8,192 bits. The complete JSON output is limited to 1,000,000 characters; approximate numbers preserve their stored values. Unsupported states fail explicitly.

Common questions

Does the larger interest total identify the wrong choice for my account?

It describes only this fixed monthly model. Account terms, daily accrual, changing minimums, behavior and other costs can differ; the report makes no personal recommendation.

Are my model inputs saved or sent to a server?

No. This model runs in the current browser tab and creates a local JSON download. It does not save your input or call an external data service.
