Barb wants a retirement income of $$5,000$ at the beginning of each month for $25$ years. If she is able to earn a return of $7\%$ on invested assets, she needs $$700,000$ to fund her income. However, this does not include any inflation adjustment. By incorporating a $3\mathrm{.}5\%$ inflation factor, what is Barb's approximate funding requirement increase, stated at the time of retirement, if she wants to maintain the same purchasing power of her $$5,000$ monthly payment?

I set BA II Plus calculator to BEG mode, $12$ payments per year, and clear the memory:

$25,$ shift, N$.$ For the TI BA II$+,25,2$ND$,$ xP$/$Y$,$ N$.$ The result should be $"300\mathrm{.}0000."$ This is $25$ year times $12$ months$/$year$.$

$3\mathrm{.}3816,$ I$/$YR$.$ For the TI BA II$+,$ I$/$Y$.$

$5000,$ PMT

CPT PV Solution: should be $-$$$1,014,385\mathrm{.}32$;

But I kept getting PV result as: $0\mathrm{.}0000*$ on my BA II calculator.

I$\text{'}$m sure I have cleared all memories of the calculator by $2$nd$,$ FV$,2$nd$,$ CE$/$E;

Can anyone help me to identify why I kept getting this error?

Thank You!
