Dividends can be a powerful tool for investors to create cash flow from their investment portfolio. A dividend calculator can be used to project future cash flows by taking into account dividend yield, dividend growth and the length of time in which you will be investing and/or reinvesting dividends. All three play a huge role in creating a sustainable portfolio of cash flow producing assets. Remember time is key but playing around with the calculator and seeing where you need to be to achieve the desired cash flow can help create an investing plan tailored to your needs.
