  2. 2Add an extra payment to measure interest and time savings.
  3. 3Include recurring new charges to see whether the balance can still decline.

Frequently asked questions

Why can a payment fail to pay off the card?+

If interest plus new charges are at least the total payment, the balance will not consistently decline.

Does this model minimum payments?+

No. It assumes a fixed monthly amount, which makes payoff timing easier to plan.

Are fees included?+

No. Late fees, annual fees, promotional APR changes, and daily interest timing can change the result.
