Someone deposits $200 every 6 months into an account that pays interest at 4% per year compounded quarterly. How much does this person have after 10 years?
Explanation : To find the future value we use following formula
Where,
FV = Future Value
A = Regular Withdrawal Amount OR Regular
Interest OR Regular Dividend OR Installment
Amount
n = Number of Years/Period
r = Compound Interest Rate
r(p)=Annual Nominal Rate of
Interest
Given :
Number of Periods/Years (n) = 10
Nominal Rate Of Interest (r(4)) =
4%
Regular Withdrawal (A) = $ 400
Benefit paid annually
A=200∗2=400
Calculating Effective Interest Rate
Effective Interest can be calculated by following formula,
where
r=Effective Rate of Interest
r(p)=Nominal rate of interest
compounded p- times a year
Therefore,
Calculating Nominal Interest Rate
Nominal Interest can be calculated by following formula,
where
r=Effective Rate of Interest
r(p)=Nominal rate of interest
compounded p- times a year
Therefore,
After substituting the values into the formula we have,
The future value is $4864.
