Growth Rate of a company

Anyone, please explain how to calculate growth rate and discount rate while calculating share price using the free cash flow model? What all parameters do we need to check while selecting a discount rate??

You should check out this module on Varsity, will help you.

Thank you so much, sir, but I have read all the modules in Fundamental analysis, but still, a bit confused as to how Karthik sir chose the growth rate of Amara raja ltd. Are the companies in a midcap range have a growth rate of 18-20% and large-cap have about 15-18%. Is this the criteria for choosing a growth rate, or do we need to do some sort of calculations??
Kindly help??
