Scenario loaded from shared link.

  • Interest accrues monthly using APR ÷ 12.
  • Payments are applied once per month (modeled as end-of-month timing).
  • Fixed minimum: minimum payment stays constant each month (unless you change it).
  • Percent minimum: minimum is calculated as “percent of current balance” with an optional floor.
  • If the payment does not exceed monthly interest, the balance may not decline (negative amortization).
  • No late fees, annual fees, promo/teaser rates, penalty APR changes, or issuer-specific minimum rules beyond what you enter.
