Credit Card Payoff Calculator by Rangi Works is a free Android application that helps users pay off their credit card debt. With this app, you can add multiple credit card accounts, select from three different pay off methods, and see when you will be credit card debt-free. You can also view how much interest you will be expected to pay and manage your in-app credit card accounts.

The app calculates the minimum payment by taking 1% of the balance and adding the total accrued interest for that month. Note that some credit card companies use other methods, so always make sure to at least pay the minimum on your statement. If the calculated minimum payment is below the absolute minimum payment you set when you added your account, the absolute minimum payment will become your minimum payment.

All balances are compounded monthly for interest calculations, and there is no grace period, so interest will be accrued starting the first month. The Interest Weighted Average pay off method allocates your budget based on the weight of interest accrued, bringing down your debt balance of your cards as evenly as possible while trying to minimize the total interest paid.

Overall, Credit Card Payoff Calculator is an easy-to-use app that can help you get out of debt. However, some users have reported technical issues with the app.
