Randall Raye invested $5,000 in a certificate of deposit for 3 years. The certificate earns interest at an annual rate of 6.25 percent compounded quarterly.

What is the effective annual yield to the nearest thousandth of a percent?

Example 1Example 1

Find the interest for 1 year. (Refer to the Amount of $1.00 Invested—Daily, Monthly, and Quarterly Compounding table on page 800 of your textbook.)

Amount – Principal

($5,000.00 × 1.063980) – $5,000.00

$5,319.90 – $5,000.00 = $319.90

Galeno Villarreal can invest $10,000 at either 4.75 percent compounded daily for 4 years or 5 percent compounded quarterly for 4 years.

Based on an effective annual yield, which is the better investment?

Example 2Example 2

Find the interest for 1 year and the annual yield.

Daily: ($10,000 × 1.048643) – $10,000.00

$10,486.43 – $10,000 = $486.43

Yield: $486.43 ÷ $10,000.00 = 0.048643 or 4.864%

Example 2 Answer: Example 2 Answer: Step 1Step 1

Quarterly: ($10,000 × 1.050945) – $10,000.00

$10,509.45 – $10,000 = $509.45

Yield: $509.45 ÷ $10,000.00 = 0.050945 or 5.095%
