Traditional vs. Roth IRA: Understanding the Differences

Individual Retirement Accounts (IRAs) are tax-advantaged investment accounts designed to help you save for retirement. The two main types are Traditional IRAs and Roth IRAs, each with distinct tax advantages.

Traditional IRA
  • Tax Treatment: Contributions may be tax-deductible in the year they are made, reducing your current taxable income.
  • Growth: Investments grow tax-deferred, meaning you don't pay taxes on capital gains or dividends while the money remains in the account.
  • Withdrawals: Distributions in retirement are taxed as ordinary income.
  • Required Minimum Distributions (RMDs): You must start taking distributions at age 72 (73 for those born after 1960).
  • Income Limits: No income limits for contributions, but deductibility may be limited if you have access to an employer retirement plan.
Roth IRA
  • Tax Treatment: Contributions are made with after-tax dollars (no immediate tax deduction).
  • Growth: Investments grow tax-free.
  • Withdrawals: Qualified distributions in retirement are completely tax-free.
  • Required Minimum Distributions: No RMDs during the original owner's lifetime.
  • Income Limits: There are income limits that may restrict your ability to contribute directly to a Roth IRA.
Which IRA Is Right for You?

Choosing between a Traditional and Roth IRA often depends on your current tax situation versus your expected tax situation in retirement:

  • Choose Traditional: If you expect to be in a lower tax bracket in retirement than you are now.
  • Choose Roth: If you expect to be in a higher tax bracket in retirement or want tax-free withdrawals.

Many investors choose to have both types of accounts to provide tax diversification in retirement.

Contribution Limits (2025)

The IRA contribution limit is $7,000 per year ($8,000 if you're age 50 or older). This limit applies to the total of your Traditional and Roth IRA contributions combined.

What Is the IRA Calculator?

The IRA Calculator is a retirement planning tool that helps you estimate how your savings will grow in an Individual Retirement Account (IRA) over time. It allows you to compare the benefits of a Traditional IRA versus a Roth IRA based on your income, age, and tax expectations. This tool can also display how inflation and taxes impact your long-term retirement savings.

Why Use an IRA Calculator?

Whether you’re getting started or refining your financial retirement planning, this calculator can be a key resource in:

  • Projecting your future IRA balance at retirement
  • Estimating the after-tax value of your retirement savings
  • Comparing Traditional vs Roth IRA outcomes
  • Visualizing inflation-adjusted returns
  • Understanding your IRA contribution limits

Key Formula Used

The calculator applies compound interest to model your balance over time. It uses the following formula to estimate account growth:

\( \text{Future Value} = P \times (1 + r)^n + \sum_{i=1}^{n} C \times (1 + r)^{n-i} \)

Where:

  • P = Current IRA balance
  • C = Annual contribution
  • r = Expected annual return (as a decimal)
  • n = Number of years until retirement

How to Use the IRA Calculator

To use this financial retirement planner effectively, follow these steps:

  1. Enter your current age and desired retirement age.
  2. Fill in your annual income and current IRA balance.
  3. Specify your annual contribution (up to the 2025 limit of $7,000).
  4. Set an expected annual return rate (e.g., 7%).
  5. Provide your current tax rate and your estimated tax rate in retirement.
  6. Adjust for inflation if you'd like to see real-dollar projections.
  7. Select whether you want to compare both IRA types or focus on one.
  8. Click “Calculate IRA” to see results, or “Reset” to start over.

FAQs

What is the difference between a Traditional IRA and a Roth IRA?

A Traditional IRA offers tax-deferred growth and may provide a tax deduction on contributions. You pay taxes when withdrawing in retirement. Roth IRAs are funded with after-tax dollars, and qualified withdrawals are tax-free.

How does inflation affect my retirement savings?

Inflation reduces the purchasing power of money over time. The calculator lets you view inflation-adjusted values so you can see your savings in today's dollars.

What is an RMD?

RMD stands for Required Minimum Distribution. These are mandatory withdrawals you must take from a Traditional IRA starting at age 73 (for most people). Roth IRAs do not require RMDs during the account holder’s lifetime.

Can I use this calculator with a 401K or annuity?

While this tool is specific to IRAs, similar tools like a 401K contribution guide or an annuity payout calculator can help you plan for those savings as well.

What if I exceed the Roth IRA income limits?

If your income exceeds the Roth eligibility threshold, the calculator will notify you. You may still explore options like a backdoor Roth IRA with guidance from a tax professional.

Final Thoughts
