Assume an 18-month CD purchased for $7000 pays an APR of 5% compounded monthly. What is the APY?

APY=____%

1 answer

P=Po(1+r)^n. Calculate int. for 1 year.

r = (5%/12)/100% = 0.00417 = Monthly %
rate expressed as a decimal.

n = 12comp./yr. * 1yr. = 12 Compounding
periods.

P = 7000(1.00417)^12 = $7358.13

I = P-Po = 7358.13 - 7000 = $358.13

APY = (I/Po)*100% = (358.13/7000)*100% = 5.116%
