Personal Finance The magic of compounding
Review of yesterday… • Why do we need to set goals? • What is meant by pay yourself first? • What is an opportunity cost and how does it apply to Personal Finance? • What amount should working adults save out of each paycheck?
Today’s Discussion • The Magic of Compounding • The Rule of 72
Einstein on Compounding • “the greatest mathematical discovery of all time.”
Compounding Growth • How your money grows over time • Think of a snowball rolling down a mountain • Amount of growth is based on: • How much money you invest • How long you set aside your money • How much your invested money grows each year (return)
Examples – The $100 investment(no compounding, simple interest) Interest = P X R X T $10 = $100 X .10 X 1 P = Principle R = Rate T = Time
Linear Savings ($100 a year w/ no growth) vs. Compound Investing
Calculating Compound Growth • Where • P = Principle • r = annual return (stated as decimal) • n = number of times compounded (4 = quarterly) • t = number of years
Sample Calculation - Compounding • An amount of $1,500.00 is deposited in a bank paying an annual return of 4.3%, compounded quarterly. Find the balance after 6 years.
Compounding CalculationNow You Try • An amount of $1,000.00 is deposited in a stock account earning an average annual return of 12.4%, compounded quarterly. Find the balance after 10 years.
The moral of the story! • To create wealth and live without financial worry you must • SAVE MONEY! • Take advantage of the miracle of compounding by investing in stocks, bonds, and other high growth methods
Growth Rates • How fast your money grows (percentage) • Generally, the more risky an investment the higher POTENTIAL return • Bank savings account: 0 – 3% • Money market account: 2 – 5% • Average stock market return: 10 – 12% • Exceptional stock market return: 13+ %
Compounding at different rates of growth - $100 initial investment Note the dramatic difference between a 5% return and an 11% return…
Amount Invested – Growing a $1,000 investment Add your age to each Year listed to see how compounding can work in your lifetime…i.e., add 17 to year 10. You could grow your initial $1,000 to $3,395 by the time you turn 27.
The Rule of 72 • Trick to see how long it will take for your money to double at a given growth rate. • Take the average annual growth rate and divide 72 by that number • Example: 11% return rate • 72/11 = 6.5 • 6.5 years for your money to double
Rule of 72…You Try • How long will it take your money to double if you earn a 8% return? Answer: 72 / 8 = 9 Years
Amount Invested – $100 each year (or 27 cents a day!) @ 11% Notice how much quicker your nest egg grows with consistent savings…(it took us 40 years to reach $6,500 with one investment of $1,000).
The incredible power of time…who finishes with the most money at age 65? Bob Kristie Begins investing at age 15 $1,000 in stock market each year Earns 11% return Stops investing at age 30 Total invested = $15,000 • Starts investing at age 35 • $5,000 in stock market each year • Earns 11% return • Stops investing at age 65 (30 years) • Total invested = $150,000
In summary • Power of compounding depends on • How much you invest • How regularly you invest • What the growth rate is • How long you let your money grow
