Just wondering what the excel formulas would be to answer this question.

If Tom invests in SPY, how much does he need to save each month to have $1 million when he retires in 40 years? If he invests in BND? Assume deposits occur at the end of each month. What is the PV, FV, N, PMT, and Rate for this problem? PV: FV: N: Pmt: Rate: Finally, assume Tom retires with $1 million in his retirement account. If he moves his money to a "safe" account at a bank, paying 3\% annual compound interest, how much can he withdraw each month in retirement (assume he waits one month after retirement to make his first withdrawal and that he will live 20 years after retiringl? What is the PV, FV. N. PMT, and Rate for this problem? FV: N: Pmt: Rate
