Compound interest:
The following formula shows how to calculate compound interest annually.
Year 1:
$____________ x ____________ = $____________+ $____________ = $____________
Principal Interest Rate Interest Earned Principal New Principal
(ex: 5% = .05) for Following Year
Year 2:
$____________ x ____________ = $____________+ $____________ = $____________
Principal Interest Rate Interest Earned Principal New Principal
(ex: 5% = .05) for Following Year
Year 3:
$____________ x ____________ = $____________+ $____________ = $____________
Principal Interest Rate Interest Earned Principal New Principal
(ex: 5% = .05) for Following Year
Based on the above formula for compound interest, how much total savings would you have:
If you put $100 in a savings account with a 3% APR for 2 years?
If you put $500 in a CD with a 5% APR for 3 years?
If you put $1,000 in a money market account with a 4% APR for 4 years?
If you put $5,000 in a CD with a 6% APR for 5 years?
The rule of 72 provides an easy way to obtain a rough estimate of how quickly your money can grow
based on a compounded fixed interest rate. Divide 72 by the interest rate you are earning and that will
tell you the number of years it will take to double your money. You can also divide 72 by the number of
years you want it to take to double your money to determine the interest rate you’ll need to accomplish this.
Here are a few examples of the rule of 72 in action:
At 5% interest, your money will take 72 ÷ 5 or 14.4 years to double.
To double your money in 10 years, you need an interest rate of 72 ÷ 10 or 7.2%.
Let’s practice the rule of 72:
Rate of Return # of Years
The rule of 72 is a simplified formula and is intended to provide only an estimate, since it loses its
accuracy as the interest rate increases.
