please help me find the amount of money i will need the day i retire in order to support my lifestyle thank you!

I would like to be 65 by the time I am retired so I can enjoy the outdoors and I want to be able to travel the world. With all the crazy stuff that I want to do I would like to live Until I am 80 after retirement so I can say that I live a crazy life with all the stuff I would like to do. I want to at least pull 50,000 dollars from my retirement account and put int into one of my savings accounts. What is the amount in my account that I need to retire with an annual rate of 16%
