Roth vs Traditional IRA: How to Choose

A Traditional IRA and a Roth IRA hold the exact same kinds of investments and share the same annual contribution limit. The whole decision really comes down to one question: would you rather get a tax break now, or tax-free withdrawals later?

Traditional IRA: tax break today

Contributions to a Traditional IRA are typically tax-deductible in the year you make them (subject to income and workplace-plan rules), which lowers your taxable income right now. In exchange, withdrawals in retirement — both your original contributions and everything they've grown into — get taxed as ordinary income.

Roth IRA: tax-free tomorrow

Roth contributions are made with money you've already paid tax on, so there's no deduction today. The payoff is that qualified withdrawals in retirement, including decades of growth, come out completely tax-free. Roth IRAs also come with income limits on who can contribute directly, worth checking before you commit to this route.

	Traditional IRA	Roth IRA
Tax on contribution	Often deductible now	None — already taxed
Tax on withdrawal	Taxed as ordinary income	Tax-free if qualified
Required withdrawals	Generally required starting at a certain age	Not required during the original owner's lifetime
Best when	You expect a lower tax rate in retirement than today	You expect a similar or higher tax rate in retirement than today

A simple heuristic

A common rule of thumb: if you're early in your career and likely sitting in a lower tax bracket now than you'll be later, Roth tends to edge out, since you're paying tax at today's lower rate. If you're already in your peak earning years and expect a lower bracket in retirement, a Traditional IRA's upfront deduction often wins. Nobody can predict future tax rates with real confidence, which is exactly why a lot of people split contributions between both account types just to hedge that uncertainty.

One piece of a bigger plan

Whichever account type you land on, the growth math works identically — years invested, contribution amount, and return assumption all compound together the same way. Our retirement and FIRE calculator lets you project that growth regardless of which account structure you choose, so you can leave the account decision purely to taxes and let the calculator handle the rest.
