Low Cost Index Funds Calculator

Your Future Value will be:

Introduction: Investing in Low-Cost Index Funds can be a smart financial move. To help you plan your investments effectively, we’ve created a calculator that estimates the future value of your investments based on your initial investment, monthly contributions, expected annual returns, and investment period.

Formula: The calculator uses the compound interest formula to calculate the future value:

FV = P(1 + r)^n + (C * ((1 + r)^n – 1) / r)


  • FV is the future value of the investment.
  • P is the initial investment.
  • r is the monthly interest rate (annual interest rate divided by 12).
  • n is the total number of months (investment period multiplied by 12).
  • C is the monthly contribution.

How to Use:

  1. Enter your Initial Investment.
  2. Input your Monthly Contribution.
  3. Specify the Investment Period in years.
  4. Provide the Expected Annual Return as a percentage.
  5. Click the “Calculate” button to see the estimated Future Value of your Low-Cost Index Funds investment.

Example: Let’s say you have an initial investment of $10,000, plan to contribute $500 monthly, expect an annual return of 7%, and want to invest for 10 years. Using our calculator, you would find that your future value would be approximately $89,927.14.
