Shark Tank show example:
Having a fundamental understanding of the future and present value of money (time value of money) is so important.
Whether you are valuing a business or projecting your investments into the future, this clarifies how money is valued now and in the future.
Shark Tank, the tv show on ABC, sometimes gets into this. For example, if they are asking for $100k for 20% of their business, their owners are putting a $500k current valuation on the business. An easy cheat to do this is by taking (100/Percent)* asking price). So in the above example, (100/20)= 5 * 100k = 500k
Part of the calculus for Mr Wonderful, Mark Cuban and friends is discounting the expected cash flows in the future to the present.
Next time you watch Shark Tank think about this aspect.
