Question

A passbook savings account has a rate of 9 %. find the effective annual​ yield, rounded to the nearest tenth of a​ percent, if the interest is compounded monthly.

Answer 1

9.38%

Step-by-step explanation:

effective annual yield = (1 + monthly rate)¹² - 1

where monthly rate = 9% / 12 = 0.0075

effective annual yield = (1 + 0.0075)¹² - 1 = 1.0938 - 1 = 0.0938 or 9.38%

The advantage of compound interest is that earned interest will earn more interest by itself.

Answer 2

Calculating Effective Annual Yield

Y= (1+(r/n))^n-1

9.381% = 9.4%
