How this calculator works

Each month: interest = balance × r, then balance −= (payment − interest)

r
the monthly interest rate
payment
the total you pay, including any extra

Important considerations

  • If the payment does not cover the monthly interest, the balance never clears.
  • Assumes no further spending on the account.

Frequently asked questions

Should I clear the smallest balance or the highest rate first?

The highest rate saves the most money; the smallest balance builds momentum. Use the snowball calculator to compare the two.
