Casio fx-9860GII Instruction Manual

3. Press w(Compound Interest).
4. On this screen, n = number of interest periods,
I% = annual interest rate, and PV = principal or present
value. Since she has not made an investment yet, the
PV is 0. PMT = the payment. Amy will invest $100 (-100)
each month. Therefore PMT will be -100 x 12. Enter 0
for FV, since that will be calculated. Enter 1 for P/Y since
interest is compounded annually. Then press y(FV).
5. Amy saves $113803.59 in her annuity over 35 years.
