Single credit card calculator

Let's get that balance to $0!

Welcome to the magical and wonderful calculator!

If you have any questions, issues, or suggestions, please contact us!

What this calculator does

If you are carrying a balance on a SINGLE credit card (not paying it off completely each month), this calculator is your jam. Using this, you can see how long it will take to pay off your credit card and how much interest you will pay.

If you have MULTIPLE credit cards with a balance, we have another calculator for that.

Okay, how do I work it?

  1. Do one of the following:
    • Enter how much you are able to pay towards your credit card debt every month.
    • OR enter your ideal number of months to pay off the card.
    • (Every time you switch this option, it will recalculate automatically)
  2. Put in the info about your credit cards.
  3. (Optionally) Click 'toggle options' and change options as you see fit. There is more info about them below.
  4. Hit calculate and check out the results!
  5. Rinse and repeat as needed, tweaking numbers and options to compare.

Helpful notes

If you're viewing this on your phone, the tables may look better if you hold your phone sideways (in landscape mode).

This calculator assumes that you start out with a balance and it only goes down. In other words, it assumes you aren't charging anything on your credit cards. If you'd like a calculator that didn't assume this or had some other feature, please let us know.

This calculator uses daily compounding interest as default. This is how many credit cards charge you interest, check your statement or Terms and Conditions to confirm which method your card uses. You can change the compounding period in the options.
