Frequently Asked Questions
How is my debt-free date calculated?
It applies your monthly payments against your balances and interest to project the month you reach a zero balance.
How can I become debt-free faster?
Adding extra to your highest-priority debt and avoiding new borrowing can move your freedom date up by months or years.
Should I pay highest rate or smallest balance first?
Highest-rate first saves the most interest (avalanche), while smallest balance first builds momentum (snowball) — both work.
