Roth vs Traditional IRA: How to Choose (With Simple Examples)
Roth vs Traditional IRA is fundamentally a tax timing decision:
- Roth IRA: pay taxes now, potentially tax-free withdrawals later (if rules are met)
- Traditional IRA: potentially reduce taxes now, pay taxes on withdrawals later
To compare scenarios with your assumptions, use the Roth vs Traditional IRA Calculator.
The simplest decision framework
Many people start with this rule of thumb:
- If you expect your tax rate to be higher later, Roth can be attractive.
- If you expect your tax rate to be lower later, Traditional can be attractive.
But real life includes:
- contribution limits and eligibility rules
- employer retirement plans
- future income uncertainty
Example: taxes now vs taxes later
If you contribute $6,500:
- Traditional might reduce taxable income today (if deductible)
- Roth does not reduce taxes today, but qualified withdrawals can be tax-free
For a quick estimate of how taxes affect your current paycheck, use the After-Tax Income Calculator.
How growth changes the decision
The more growth you expect over decades, the more valuable Roth’s tax-free withdrawals can be—assuming your tax rate later is not dramatically lower.

FAQ
Is Roth always better for young people?
Not always, but younger savers often have lower current tax rates and longer time horizons, which can make Roth appealing.
Can I do both Roth and Traditional?
In many cases, yes (subject to limits and eligibility). Some people diversify tax exposure by contributing to both.
Are Traditional IRA contributions always deductible?
Not always. Deductibility depends on income and whether you or your spouse have a workplace retirement plan.
Are Roth withdrawals always tax-free?
Qualified withdrawals can be tax-free, but there are rules (including holding period and age requirements).
How should I decide if I’m unsure?
Model multiple scenarios with different tax rates and time horizons. The Roth vs Traditional IRA Calculator is designed for that comparison.
