  2. Enter the APR (interest rate).

Example

  • Balance: $10,000
  • APR: 18%
  • Minimum: $200
  • Extra: $100
47 months with extra vs 94 months minimum only · Saves $4,780 in interest

Adding $100/month cuts payoff time in half and saves nearly $4,800 in interest — one of the highest-return 'investments' available if you're carrying high-interest debt.

Frequently asked questions

+What is the debt snowball method?

The debt snowball method pays off smallest debts first for psychological wins. The avalanche method targets highest-interest debts first to minimize total interest. Snowball feels better; avalanche saves more.

+Should I pay off debt or invest?

Generally, pay off any debt with an interest rate above 7–8% before investing. High-APR credit cards (18%+) are a guaranteed negative return — crush them first.

+Does paying extra early matter?

Hugely. Early extra payments compound by reducing interest on the entire remaining balance for every month that follows. A dollar paid early is worth much more than a dollar paid later.
