Future value plus annual contributions
 

I have the formula that will calculate the future value of an investment
using variables for the investment amount, interest rate and number of years
(=A1*(1+C1)^B1). In addition I want to add another variable to the formula
that adds an annual "contribution" to the investment and includes the annual
contribution in the compounding formula. Can someone help?

Thanks.

Check the FV (future value) function. What you've got so far is the FV with
a 0 payment, and what you're trying to do is the FV with both a payment and a
PV.

Hello:

An alternative:

If you wanted to stick with a formula similar to the one you are already
using this will work:

Future Value = (Annual amount)*((1+i)^periods)/i

Just add the amount you got for the lump sum to results of the above.
