Traditional IRA
$442,508 pre-tax, $345,156 after 22% retirement tax. Roth IRA: after-tax contribution of $5,320/year grows to $336,305 fully tax-free. The Traditional IRA edges ahead when the retirement tax rate is lower than the current rate.
Tips
Run Multiple Tax Scenarios
Try different retirement tax rates (15%, 22%, 25%) to see where the crossover point is. Small changes in the retirement rate can flip which IRA type wins.
Consider Tax-Free Withdrawal Flexibility
Roth IRA withdrawals do not count as taxable income, which means they do not trigger Medicare IRMAA surcharges or increase taxation of Social Security benefits.
Factor in RMDs
Traditional IRAs require minimum distributions starting at age 73, which could push you into higher tax brackets. Roth IRAs have no lifetime RMDs.
Frequently Asked Questions
What is the main tax difference between Traditional and Roth IRAs?
Traditional IRA contributions may be tax-deductible, giving you an upfront tax break, but withdrawals in retirement are taxed as ordinary income. Roth IRA contributions are made with after-tax dollars, but qualified withdrawals are completely tax-free.
Do Roth IRAs have required minimum distributions?
No. Original Roth IRA owners are never required to take RMDs. Traditional IRAs require minimum distributions starting at age 73 (or 75 for those born 1960+). This makes Roth IRAs especially valuable for estate planning and tax management in retirement.
Can I have both a Traditional and Roth IRA?
Yes, but your combined contributions to both cannot exceed the annual limit ($7,000 for 2025, $8,000 if 50+). Many investors split contributions between the two types for tax diversification in retirement.
