How does this debt payoff calculator work?

It estimates your payoff timeline using your balance, APR, monthly payment, and extra payment. Increasing your payment shortens your debt-free date and reduces interest.

What is the best debt payoff strategy?

Debt Snowball helps with motivation by paying off smaller balances first. Debt Avalanche saves more in interest by attacking higher APR balances first.

Can I track multiple debts?

Yes. The Debt Free app supports unlimited debts, all payoff strategies, iCloud sync, reminders, and progress tracking across iPhone and iPad.
