How to read this estimate

Avalanche payoff order: Store card (month 10), Credit card (month 30), Car loan (month 38)

Snowball payoff order: Store card (month 10), Credit card (month 30), Car loan (month 38)

The monthly budget stays fixed as debts disappear. Minimum payments are fixed dollar assumptions and freed payments roll to the next debt. Avalanche targets highest APR; snowball targets smallest balance.

Monthly APR/12 interest approximation, no new charges, fees, promotions or rate changes. Actual credit-card daily interest and changing minimums differ. A dash means not paid off within the 600-month model, not a promise of eventual payoff.
