Graphing your interest rate with annual deposits

Although the project should have already been turned in, I leaened of an equation that could have been useful in doing the project. This equation is for graphing the compound interest rate alomg with annual deposits of whatever amount you choose to save. The equation goes as shown:

P=D(1+i)^(t)*(1/i)
P=principle
D=deposit
t=years
i=interest rate

Example:
I am going to save $2400 a year to invest in a company with a company with a %10 interest rate. How much will I have by 5 years?

P=2400([1+0.10]^[5]-1)*(1/0.10)
P=2400([1.10]^[5]-1)*(10)
P=2400(1.61051-1)*(10)
P=2400(0.61051)*(10)
P=2400(6.1051)
P=14652.24
After those 5 years, I would have $14652.24 in my account balance.

In conclusion, if you ever need to do another investment project yourself or perhaps have any other needs for it, you can easily display the your earnings over the years.
