Rental Property Cash Flow Calculator

Welcome to the Invest Four More cash flow calculator. This calculator does not just figure your monthly cash flow based on your mortgage payments and rent; it figures your real cash flow. It uses mortgage payments, taxes, insurance, property management, maintenance, and vacancy factors. Not only does it allow you to enter your maintenance and vacancies into the calculator, but it also gives you a table with suggested values based on the age and condition of the home.

The calculator provides three categories for condition based on homes being in ready to rent condition. This calculator will give you a great idea of what the actual cash flow will be on your property. A much more detailed explanation of the calculator and how we came up with the default values can be found here.

Instructions for the cash flow calculator

  1. You will need to reference two tables for Maintenance and Vacancy values. These tables are below the calculator.
  2. For mortgage rates we have provided a link to Bank Rate’s mortgage information
  3. To figure taxes and insurance we have provided links to Zillow. Simply search for your target property or one similar. Scroll down to the property details and you will find estimated tax and insurance values. Cells highlighted in green will show your results.


Once you have determined your cash flow, you can use the cash-on-cash calculator to see what return that cash flow is giving you on your cash invested.

I also have a fix and flip and calculator here: Fix and flip calculator.
