Intro to Financial Management The Time Value of Money

Review Homework How do you calculate and what do these ratios mean? Current ratio Acid-test Inventory turnover ROS, Return on sales ROA, Return on assets ROE, Return on equity Debt ratio Leverage ratio P/E

Review What is on an income statement? What is on a balance sheet? What is common-sized? What are gross profit margin, operating profit margin, net profit margin, earnings, and earnings per share? What do these terms tell you? What is on a balance sheet? What are book value, working capital, debt and leverage ratios? What is on a cash flow statement? What are the three major areas of cash flow? Why is this different from profit? What are the basics of computing corporate taxes?

The Time Value of Money Would you loan $1000 today and want $1000 in ten years? Examples Lottery Mortgage Banking Foregoing money today for money in the future “Opportunity cost” Interest is the cost of money

Future Value (FV) If you invest a lump sum today, what will it be worth in the future? Compounding interest No more new money put in Receive interest each year; it builds up Future value Formula Future value factor

Calculating FV Calculating future value. Excel and calculator. Must have both a positive and negative number May also need to solve for n E.g. How many years will it take to reach $1M? May want to know r E.g. What interest rate do I need to reach $1M in n years? Examples How long to get to $1M? Here you have to solve for n. On a calculator with PV/FV, enter the data and CPT n On a calculator without PV/FV, the formula is n = log(FV/PV) / log(1+r) (you can also use ln instead of log)

Present Value (PV) What is a single payment in the future worth today? Future money can be expressed in today’s dollars. Formula Present value factor Calculate using calculator and Excel Example What is $10,000 ten years from now worth today at 4% interest? How do we deal with two different flows? E.g. $5k in 5 years plus $10k in 10 years

Annuities Series of equal payments Want to know either How much you would pay today to receive those payments in the future or If you are investing those payments, how much will they be worth in the future

Simple Annuity Receive the same payment every year for n years What is that worth now? I.e., what would you pay now to get that annuity? PV = PMT * (1 – present value factor) / r

Compound Annuity You invest the same amount each period for n periods The value grows as you: Receive interest on your balance Invest new money each year FV = PMT * (future value factor – 1) / r

Amortized Loans Loans where you pay back the principal plus interest in equal payments throughout the period E.g. a mortgage Treat like a simple annuity and solve for PMT PV is the amount of the loan, what you are given n is the number of periods For a 30-year mortgage, you have 12*30 periods because they are paid monthly r is the interest rate For a mortgage, take the interest rate and divide by 12 (you pay 1/12th each month) Solve for PMT The payments include both interest and principal Example, how big a mortgage can you get if you can afford $1250 a month for 30 years at a rate of 4%?

Comparing Interest Rates Interest can be calculated in many ways Compare annual interest of 1% and monthly at 1% Need a common benchmark Annual percentage rate (APR) Also known as effective annual rate (EAR) FV and PV for non-annual periods (m periods in a year) General case of a mortgage. Instead of n, substitute n*m Instead of r, substitute r/m

Perpetuity An annuity that continues forever PV = PMT / r What is the value of a perpetuity that pays $1000 if the interest rate is 8%?

Summary Today Periods Payments Future Type Formula ?? n -- $FV Simple PV =PV() $PV Simple FV =FV() Receive $PMT Simple Annuity - Invest $PMT Compound Annuity $PMT = NPER() =RATE() forever Perpetuity PV = PMT / r

Problem Congratulations, you just won the lottery for $25 million. The lottery will pay you $100,000 a year for 25 years What is the cash value of this lottery, assuming an interest rate of 8%? What would you do if the cash value offered by the state was less or more than the amount you calculated?
