Frequently asked questions

How do I speed up becoming debt-free?

Increase your monthly payment above the minimum, avoid taking on new debt while paying this off, and consider tackling higher-interest debts first if you have multiple — see the Debt Avalanche Calculator for a multi-debt strategy.

What if I have multiple debts?

This calculator handles one debt at a time — for a strategy across several debts simultaneously, use the Debt Snowball or Debt Avalanche Calculator instead.

Does a higher payment always mean a proportionally shorter payoff time?

Not exactly — because interest compounds on the remaining balance, doubling your payment typically more than halves your payoff time, since less total interest accrues along the way.
