He already has 2500 dollars.

If he saves his money with monthly compounding, that will be worth 2903.680578 at the end of 3 years from today.

Since he wants to have a total of 25000 in 3 years, then we subtract this from 25000 to get 22096.31942 which is the additional money he will need in 3 years.

Assuming monthly compounding, he would need to make payments of 570.1785182 per month for 36 months to equal 22096.31942 at the end of 3 years.

Today he has 2500 which will be worth 2903.6805787 in 3 years.

He is making monthly payments of 570.1785182 at the end of each payments that will be worth 22096.31942 in 3 years assuming he re-invests the interest the account is earning at the end of each month.

2903.6805787 + 22096.31942 = 25000 total he will have at the end of 3 years.

This does not take into considerations taxes on the money earned which puts a whole new dimension on the calculations required.

I used a financial calculator to provide the answers but there are formulas you can apply if you don't have access to one.

I have lessons on algebra.com for future value of a present amount and payment for a future value that contains the formulas.
