How to calculate the future value of monthly investment?

Calculating the future value of a monthly investment is a valuable skill that can help individuals plan for their financial goals. By understanding how to compute this value, you can make informed decisions about saving and investing your money for the future.

To calculate the future value of a monthly investment, you need to use the formula for compound interest. The formula is:

FV = Pmt * (((1 + r)^n – 1) / r)

Where:
FV = Future Value of the investment
Pmt = Monthly payment
r = Monthly interest rate (annual interest rate divided by 12)
n = Number of months the money is invested for

Let’s break it down further with an example:

Suppose you invest $500 per month with an annual interest rate of 6%. The monthly interest rate would be 0.06/12 = 0.005.

If you invest for 10 years (120 months), the formula would be:

FV = $500 * (((1 + 0.005)^120 – 1) / 0.005)

FV = $500 * (1.78903)

FV = $894.52

So, the future value of your monthly investment after 10 years would be approximately $894.52.
