Further Detail For the Investment Calculator Inputs

See below for more detail if you’re not exactly sure what each of the entries mean.


This one is the most basic entry needed here. Simply enter in your current age!

Retirement Age

When do you plan on retiring? Enter that age here.

Also, if you simply want to see how much money you have at a certain age (not necessarily when you retire), you can enter that age here too.

Current Investment Balance

How much money do you have in your investment accounts right now at your current age? That’s the amount that needs to be placed in this cell.

*No need for dollar signs or commas, just key in the number.*

Monthly Contribution

How much do you intend to contribute to your investments each month? If you have an employer match, be sure to include those funds too!

*No need for dollar signs or commas, just key in the number.*

Expected Rate of Return

And, what percent do you expect to return on your money?

  • If your money is in a savings account, it’s probably earning you 1% or less
  • If you invest in individual stocks, the average investor earns 5%-6% this way
  • But, if you invest in an S&P 500 Index fund, history has shown you could earn 11%-12%

(I personally invest in index funds and use a 10% rate as my estimate)

*No need for the ‘%’ sign, just key in the number.*

Grow Rich Money


My name is Derek, and I have my Bachelors Degree in Finance from Grand Valley State University. After graduation, I was not able to find a job that fully utilized my degree, but I still had a passion for Finance! So, I decided to focus my passion in the stock market. I studied Cash Flows, Balance Sheets, and Income Statements, put some money into the market and saw a good return on my investment. As satisfying as this was, I still felt that something was missing. I have a passion for Finance, but I also have a passion for people. If you have a willingness to learn, I will continue to teach.
