Roth IRA Basics
A Roth IRA is a retirement account where you contribute after-tax dollars, and your money grows tax-free. Qualified withdrawals in retirement are also tax-free.
For 2024, the contribution limit is $7,000 ($8,000 if you’re age 50 or older). These limits apply to combined contributions to all your Roth and Traditional IRAs.
For 2024, single filers with modified AGI under $146,000 and married couples filing jointly under $230,000 can make full contributions. Phase-outs apply above these amounts.
You can withdraw contributions (but not earnings) at any time without penalty. To withdraw earnings tax-free, you must be at least 59½ and have held the account for 5 years.

3. How a Roth IRA Calculator Works
A Roth IRA calculator projects future account balance and tax benefits based on:
- Current Roth IRA balance
- Annual contribution amount (up to $7,000/$8,000)
- Contribution timing (start vs. end of year)
- Expected annual rate of return (e.g. 5–8%)
- Current age and expected retirement age
- Tax implications (for growth, conversions, and withdrawals)
Most calculators allow you to enter these variables, then provide:
- Estimated balance at retirement
- Growth of contributions vs. traditional or taxable accounts
- Comparison of tax‑treated outcomes
- Contribution eligibility checks based on income and catch‑up allowance nerdwallet.com+6calculator.net+6unbiased.com+6thrivent.com+1clark.com+1nerdwallet.com+1kiplinger.com+1unbiased.comwsj.com
