Question

Tianna invested $500 in a CD account. She earned $8 in interest. Inflation was $2. What is Tianna's rate of return? (3 points)

Answer 1

1.6%

Step-by-step explanation:

A rate of return is the total gain or loss on investment. It is usually expressed in percentage form

Rate of return on the CD is the total return derived from investing in the Certificate of deposit

Rate of return = (interest earned / total amount invested ) x 100

(8/500) x 100 = 1.6%

If we are asked to calculate the real rate of return, the inflation rate would be subtracted from the interest earned

Real rate of return =
`(8-2)/(500)` × 100 = 1.2%
