Key Points

Calculate the present value of each year's cash flow by dividing by (1 + discount rate)^number of years.
Sum all present values to find the total value of projected cash flows, which in this example is $326.
A 10% discount rate gives a fair valuation for selling a business based on projected cash flows.

The basic premise of finance is that money has time value -- a dollar in hand today is worth more than a dollar in the future. The study of finance seeks to make it possible to compare the value of a future dollar in terms of present dollars. Below, we'll show you how to calculate the present value of a stream of free cash flows expected over several years.

The last and final step is to sum up all the present values of each cash flow to arrive at a present value of all the business's projected free cash flows. We calculated the present value of the total free cash flows at $326. Thus, if you were to sell this business based on its expected cash flows and a 10% discount rate, $326.00 would be a very fair price.

Take careful note that the higher the discount rate and the longer the time period you expect to wait for each cash flow, the less value it will have in the present. Notably, in our example, we expect $110 in cash flows for the year four and year five periods. However, the year four cash flow is worth more because it is discounted by fewer periods than the year five cash flow.
