$28,453.02  

Explanation:

Using a financial calculator approach, we can determine the amount in the savings account at the end of year 6 as well as after 20 years as follows:

Balance after 6 years:

PMT=-100(  monthly deposit)

I/Y=2.1%/12( monthly interest rate)

PV=0 (initial balance before 1st deposit is nil)

N=72 (number of monthly deposits in 6 years)

lastly CPT FV=$7,666.13  

Balance after $1000 withdrawal=$7,666.13 -$1,000.00=$6,666.13

Balance after another 14 years(14+6=20)

PMT=-100

I/Y=2.1%/12( monthly interest rate)

PV=-6,666.13(balance after withdrawal in year 6)

N=168 (number of monthly deposits in 14 years)

lastly CPT FV=$28,453.02
