I am trying to figure out a function that can be used to find the balance in
a savings account after a period of time. To make it a little more
complicated, I want to include a monthly deposit during that time. Is there
a function that can do this? I am trying to develop a savings plan that will
be for a specific purchase I want to make in 5 years and want to know how
much I need to put put in the account monthly.

For example.....
If I have an account with $500 and deposit $50 dollars every month for the
next 5 years and there is a 25% annual interest rate...how much will be in it
after 5 years?

Or opposite, although I know how to do what-if anaysis if that is what it
takes...
If I want to save 10,000 in 5 years, how much would I have to deposit
monthly.

These are not the specific numbers but this is what I want it to do for me
for several different saving's projects I want to do.

I tried a couple of the suggested functions, but they didn't come out right,
and I could find anything that included adding to the account throughout the
time period. Does anyone know how to do this? And I am a not clear on all
the financial terms they use in the help mode, so if you can explain it as
simply as possible I would really appreciate it. Thanks.
