If I invest x amount each year for n number of years @ r% return, what will be my total amount after n years?

Answer 1

it wil be ?????? because there are two many variables

Answer 2

Get a financial calculator. I like the TI-83 Plus or Silver (although a bit pricey).

$100 per month for 30 years at 15% per year would turn into
= $692,327.96

Answer 3

use and excel spreadsheet.
1. in one cell put an annual amount of savings
2. in another cell put the annual interest rate (make sure you put it in as .xx)
3. in another cell put in the number of years.
4. in the cell where you want the answer to your question put in a formula using the FV (future value) financial function. Your formula will be +FV(cell ref with interest rate, cell ref with number of years, cell ref with annual amount.)

After you build this model you can put in any combination of the 3 variables that you want.

I did a simple one for you. $1000 per year, 7%, 35 years. The FV is $138,236.88.
