Planning for retirement can feel overwhelming, especially when trying to estimate how much your investments will grow over time. Whether you’re contributing to a Roth IRA, a 401k, or both, understanding the future value of your savings is crucial for financial security. This is where our Roth IRA & 401k Calculator becomes an invaluable tool. Designed for simplicity and accuracy, this calculator helps you project your retirement savings based on your current investments, monthly contributions, expected annual return, and time horizon.
Roth IRA & 401k Calculator
How the Roth IRA & 401k Calculator Works
The calculator operates on the principle of compound interest, one of the most powerful tools for growing your retirement funds. By entering a few key inputs, the tool computes three essential figures:
- Future Value – The estimated amount your retirement savings will grow to by the end of your investment period.
- Total Contributions – The cumulative amount you personally contribute over time.
- Total Growth – The difference between your future value and your contributions, showing the earnings generated by interest and returns.
This provides a clear picture of how your money will grow, helping you make informed decisions about your retirement planning strategy.
How to Use the Calculator
Using the Roth IRA & 401k Calculator is straightforward. Follow these steps to get accurate results:
- Initial Investment: Enter the amount you are starting with. This is your current savings or initial deposit in your retirement account.
- Monthly Contribution: Input the amount you plan to contribute every month. Regular contributions significantly enhance your retirement growth.
- Expected Annual Return (%): Enter the average annual rate of return you expect from your investments. Historical data shows that stocks generally yield 7-10% annually, but you should adjust based on your risk tolerance.
- Time Horizon (Years): Specify the number of years you plan to invest. A longer time horizon usually allows for more growth due to compounding.
- Calculate: Click the Calculate button. The tool will instantly display your future value, total contributions, and total growth.

The intuitive interface ensures that even beginners can easily navigate and obtain accurate retirement projections.

After hitting the Calculate button, the calculator might display:
