Saving for retirement can feel complicated, especially with different types of retirement accounts available. One of the most popular is the Roth IRA (Individual Retirement Account), known for its tax-free growth and withdrawals.
The Roth Calculator is a simple yet powerful tool that helps you project how much you could save in your Roth IRA by retirement. With just a few inputs, you can see how your money grows over time, how much you’ll contribute, and what your final balance may look like.
What Is a Roth IRA?
A Roth IRA is a retirement savings account funded with after-tax dollars. The biggest advantages are:
- Your contributions grow tax-free.
- Withdrawals in retirement are tax-free (if you meet eligibility rules).
- No required minimum distributions (RMDs) during your lifetime.
- Flexibility in choosing investments (stocks, bonds, mutual funds, ETFs, etc.).
This makes Roth IRAs especially attractive for younger savers and those expecting higher taxes in the future.
How the Roth Calculator Works
The Roth Calculator estimates your future balance by factoring in:
- Your Current Age – How old you are now.
- Planned Retirement Age – When you’ll start withdrawals.
- Current Roth Balance – Any money you’ve already saved.
- Annual Contribution – The amount you plan to contribute each year.
- Growth Rate – Your expected annual investment return (e.g., 6–8%).
- Contribution Increases – Whether you plan to increase contributions annually.
The calculator then shows:
- Total contributions made
- Estimated investment growth
- Final Roth IRA balance at retirement
Step-by-Step Guide to Using the Roth Calculator
- Enter your current age – Example: 30 years.
- Choose your retirement age – Example: 65 years.
- Add your current balance – Example: $10,000 already invested.
- Enter annual contributions – Example: $6,500 (the IRS maximum).
- Select expected annual return – Example: 7%.
- Click Calculate – Instantly see your estimated retirement savings.
Example Calculation
Let’s look at a scenario:
- Current Age: 30
- Retirement Age: 65
- Current Balance: $10,000

- Expected Growth Rate: 7%
Result using Roth Calculator:
- Total Contributions: ~$227,500
- Estimated Investment Growth: ~$650,000

That’s nearly $900,000 of tax-free money in retirement by contributing consistently.
