Creating a DCA calculator in Excel or Google Sheets

Here’s how you can do it:

  • Open a new spreadsheet in Excel or Google Sheets.
  • In the first column, list the months from 1 to 6 (representing the investment period).
  • In the second column, input the stock prices for each month. You can use random numbers to simulate price fluctuations.
  • In the third column, calculate the number of shares purchased each month by dividing the $100 investment by the stock price.
  • In the fourth column, calculate the cumulative number of shares owned at the end of each month.
  • Repeat the process for both scenarios: one with Dollar Cost Averaging (investing $100 monthly regardless of price) and one without (investing $100 when the investor deems fit).
  • Create a line graph with two lines representing the cumulative number of shares owned over the investment period for both scenarios.
  • Label the x-axis as “Months” and the y-axis as “Cumulative Number of Shares.”
  • You can also add a title to the graph, such as “Dollar Cost Averaging vs. Lump Sum Investment: Cumulative Shares Owned.”

By following these steps, you should be able to create a graph that visually compares the cumulative number of shares owned under both Dollar Cost Averaging and lump sum investment scenarios over a six-month period.
