FV and PV is used for all financial valuations..............and there are several applications of FV and PV ie. annuities, perpertuities, amortization, mixed funds, etc
mainly try to understand the interest rate you expect to receive as payment for giving a person your money is known as the "return" on your investment
TVM implies that a rational person would demand a higher return for lending their money to someone with more risk (risk = the threat that you may not receive all of your money back)
for investors, any potential investment should be analyzed by valuing the investment using TVM techniques: this helps you decide which investments to make over others based on which investment gives you higher returns
for business owners, the cash flows from profits your business creates are evaluated using TVM techniques by potential investors, and internal/external advisors and analysts..............you can't properly identify how well your business is actually doing if you can't show specifically how much return your business gives investors in comparison to other competitors
rational investors are always looking for the least risky/highest return investment............your job as a manager of your business is to minimize risk and at the same time amplify your returns: this is the key to running a successful business
