Introduction to Roth IRA Planning
A Roth IRA is one of the most powerful retirement savings vehicles available because it offers tax-free growth and tax-free withdrawals in retirement. Unlike a Traditional IRA, you contribute after-tax dollars today, meaning you don't get an immediate tax deduction, but your future self avoids taxes on every dollar earned in the account.
Quick Summary: How Much Can You Save?
For 2024, the contribution limit is $7,000 ($8,000 if age 50+). Over 30 years, contributing $7,000 annually at a 7% return could result in a tax-free nest egg of over $660,000.
Key Benefits of a Roth IRA
- Tax-Free Income: You pay $0 in federal taxes on withdrawals after age 59½.
- No RMDs: Unlike 401(k)s, you aren't forced to take money out at a certain age during your lifetime.
- Flexibility: You can withdraw your contributions (but not earnings) at any time without taxes or penalties.
- Estate Planning: Your heirs can inherit the account tax-free.
How to Use the Roth IRA Calculator
Our calculator helps you visualize how different contribution levels and rates of return impact your long-term wealth. Follow these steps:
- Enter Your Ages: Input your current age and the age you plan to retire.
- Current Balance: Enter any existing funds you already have in a Roth IRA.
- Annual Contribution: Estimate how much you will add each year (subject to IRS limits).
- Expected Return: Use a realistic figure based on your risk tolerance (e.g., 6–10% for stock-heavy portfolios).
How the Calculation Works
The Roth IRA calculator uses the future value formula for an annuity. It assumes contributions are made at the end of each year and interest is compounded annually. The formula accounts for the growth of your initial balance plus the growth of all subsequent annual contributions over the investment horizon.
Key Factors That Affect Roth IRA Growth
Three main levers determine how much you will have in your account:
- Time Horizon: The longer the money stays invested, the more compound interest does the heavy lifting. Starting 10 years earlier can often double your final balance.
- Contribution Consistency: Maximizing your contributions every year ensures you take full advantage of the tax-shielded space provided by the IRS.
- Asset Allocation: Your choice between stocks, bonds, and cash will determine your expected return. Higher equity exposure generally leads to higher long-term balances but more volatility.
Assumptions and Limitations
This calculator provides estimates based on several assumptions:
- Fixed Returns: It assumes a constant rate of return, whereas real markets fluctuate year to year.
- Tax Laws: It assumes current Roth IRA tax laws remain unchanged until your retirement.
- Contribution Limits: It does not automatically adjust for future IRS inflation-based limit increases.
- Income Phase-outs: It assumes you are eligible to contribute to a Roth IRA based on your Modified Adjusted Gross Income (MAGI).

Frequently Asked Questions

Yes, you can contribute to both as long as you meet the income requirements for the Roth IRA.

In 2024, the phase-out range for single filers is $146,000 to $161,000. For married couples filing jointly, it is $230,000 to $240,000.
Can I withdraw money from my Roth IRA before 59½?
