Frequently Asked Questions
How many debts can I track?
The Pro version supports up to 20 separate debt accounts - credit cards, student loans, auto loans, medical debt, and any other obligations.
How does the strategy comparison work?
The template calculates the full payoff timeline for both snowball (smallest balance first) and avalanche (highest rate first) strategies side by side, showing total interest and months to debt-free for each.
Can I add extra payments?
Yes. Enter any additional monthly amount beyond minimums. The schedule recalculates showing how the extra payment accelerates payoff and reduces total interest paid.
Does it show a debt-free date?
