PERT formula

  1. Jun 20, 2009 #1
    P*e^(rt) = Accumulated amount of money

    e logaritm

    is for continous compounding of rate.

    and this one works for savings that are made frequently like every month or so but only with annual compounding of rate.

    is there any way to combine these formulas and calculate the accumulated amount of money i.e. getting a formula that express continous compounding of rate for when you deposit money X times per year.

    You can find the effective monthly rate with the contimnuous formula, then use that effective rate instead of the actual rate in the other formula.
