Computation of Accumulated Amount using FV Function in Excel:

=-fv(rate,nper,pmt,pv)

Here,

FV = Future Value or Accumulated Amount = ?

Rate = 11%

Nper = 6 years

PMT = $1,200

PV =

Substituting the values in formula:

=-fv(11%,6,1200,0)

FV or Future Value or Accumulated Amount = $9,495.43

So, you will have saved $9,495.43 after 6 years by contributing $1,200 at the end of each year if you expect to earn 11% on the investment.
