To buy it, you need to find out how much it costs. When you get the price, make sure you write it down in the property value line.
  2. Then set the down payment, percentage, and the number of years you are willing to pay. Then the calculator will count your monthly payment.
  3. The app also supports multiple currencies. This option will come in quite handy if yo want to borrow the mortgage using another currency, not dollars.
  4. See the graphs. Sometimes it is hard to understand long texts or columns of numbers. This is why it’s time to turn to graphs and schemes! They will be formed automatically.

The app has a primitive interface that is simple to understand at once. When you open a Loan & Lease Calculator, you will see the page you need to fulfill. 

The app will need the following info about your loan or lease:

  2. Start date and end date. It will allow the calculator to understand the period of the financial process. Without this info calculation is impossible.

This isn’t the full amount of info you will need to give the app for the most accurate calculation. 

When you are done with the info, tap on the ‘calculate’ button, and you will see the result. It usually takes a few seconds to finish the process.

This option might come in handy if you need an apartment you would like to make a rental property or just a big sum of money. It will bring you some income every month, for instance, $500 per each month. However, you might still have doubts whether to go for it or not. In this situation, PMT will help you.
