Answer:
To calculate the amount Avi must deposit into a fund today, we can use the present value formula for an ordinary annuity:
PV = PMT * (1 - (1 + r)^(-n)) / r
Where:
PV = Present Value (amount to be deposited today)
PMT = Payment amount per period ($500 per month)
r = Interest rate per period (6% divided by 12, as it is compounded monthly)
n = Number of periods (20 years multiplied by 12, as it is compounded monthly)
Plugging in the values, we get:
PV = $500 * (1 - (1 + 0.06/12)^(-20*12)) / (0.06/12)
Calculating this equation, we find:
PV ≈ $500 * (1 - (1 + 0.005)^(-240)) / 0.005
PV ≈ $500 * (1 - 1.005^(-240)) / 0.005
PV ≈ $500 * (1 - 0.31336) / 0.005
PV ≈ $500 * 0.68664 / 0.005
PV ≈ $68,664
Therefore, Avi must deposit approximately $68,664 into the fund today in order to receive $500 per month for 20 years, with an interest rate of 6% compounded monthly.
