How do I find expected future free cash flows using growth assumptions?

I'm doing a project and have come up with a FCF for 2016. In order to find the expected future FCFs for 2017-2021, is it okay to use the following formula?

Future FCF = FCF*((1+g)^n)

g = expected dividend growth rate

FCF = FCF for 2016

n=number of years (ex., 1,2,3,4,5)

If I am totally incorrect, please break down every singe step that I have to do to find future FCF. I'm very confused and need baby steps and layman's terms. Thanks
