Roth vs Traditional IRA: Which One Wins for You in 2026?

The short answer

At $7,000 a year for 35 years at 7%, the Roth and the Traditional IRA tie: both leave you with $754,773.36 after tax when your retirement bracket matches your current one. The Traditional grows to $967,658.15 before tax and the Roth to $754,773.36 tax-free, and the 22% tax on the Traditional at withdrawal takes exactly the difference. So if you expect to retire in the same bracket you are in now, the choice is not about the balance at all — it is about flexibility, required minimum distributions, and how much cash you can put in each year. If you expect a different bracket in retirement, the winner is decided by the gap: a higher bracket later means the Roth wins, and a lower bracket later means the Traditional wins, and the size of the win is easy to calculate before you choose.

The tie, explained: $967,658.15 on both sides

The tie is not a coincidence; it is the same arithmetic wearing two costumes. The future value of $7,000 a year for 35 years at 7% is $7,000 × ((1.07)^35 − 1) / 0.07, which is $967,658.15. The Roth pays 22% tax first, so only $5,460 a year goes in, and $5,460 × the same growth factor is $754,773.36, all tax-free. The Traditional puts the whole $7,000 in, grows to $967,658.15, and then pays 22% on the lot: $967,658.15 × 0.78 is $754,773.36 again. The total contributions are $245,000 and the growth is $722,658.15, and the Roth pays $53,900 in tax over the whole period while the Traditional pays the same amount in effect at the end. The tie holds at any return, any horizon, and any contribution — as long as the two brackets match, the tax rate cancels out entirely.

When the Roth wins: a higher bracket in retirement

The Roth wins whenever your retirement bracket is higher than your current one, because it taxes the small amount now instead of the big amount later. At a 25% retirement bracket, the Traditional balance of $967,658.15 keeps only 75%, or $725,743.61, while the Roth keeps its full $754,773.36 — a Roth win of $29,029.74. The Roth also wins the max-out case by a much larger margin: if you can put the full $7,000 into a Roth after tax, the Roth ends at the full $967,658.15 tax-free while the Traditional ends at $754,773.36 after tax, a Roth win of $212,884.79. Early-career savers in a low bracket are the classic Roth winners: paying 12% now beats paying 22% or 25% later, and every year of low-bracket contributions locks that win in.

When the Traditional wins: a lower bracket in retirement

The Traditional wins whenever your retirement bracket is lower than your current one, because you take the deduction at the high rate and pay at the low one. At a 12% retirement bracket, the Traditional keeps 88% of $967,658.15, or $851,539.17, against the Roth’s $754,773.36 — a Traditional win of $96,765.81. High earners nearing retirement are the classic Traditional winners: they are in a high bracket now, they expect to live on less in retirement, and the deduction they take today is worth more than the tax they pay later. The break-even point is always your current bracket — here 22% — so the question to ask yourself is simple: will my retirement bracket be above or below 22%? Above, take the Roth; below, take the Traditional; at 22%, it does not matter for the balance.

Required minimum distributions: the tie-breaker that is not about money

Even when the balances tie, the two accounts are not the same, because the Traditional forces you to withdraw and the Roth does not. Traditional IRAs have required minimum distributions starting at age 73 — age 75 if you were born in 1960 or later — which means the government makes you take money out, and pay tax on it, whether you need it or not. Roth IRAs have no required minimum distributions for the owner, so the money can keep growing untouched for as long as you live, and it passes to your heirs tax-free. It also matters for estate planning: if leaving money behind is part of the plan, the Roth’s freedom from forced withdrawals is worth real money even when the balances tie.

The max-out trap: same dollars, different money

The most misunderstood branch of this comparison is the max-out case, and it is worth reading twice. Our calculator compares the same $7,000 a year in both accounts, but a $7,000 Roth contribution and a $7,000 Traditional contribution are not the same amount of money. The Roth contribution is after tax, so it costs $7,000 plus $1,974 of tax each year, while the Traditional contribution is before tax and costs only $7,000. When both are filled to the same $7,000, the Roth ends at $967,658.15 tax-free and the Traditional at $754,773.36 after tax — the Roth wins by $212,884.79. That is a real win, but it is not free: it costs $1,974 more cash every year, or $69,090 over 35 years, to buy it. If you cannot afford the extra cash, the comparison is misleading — compare $7,000 before tax with $5,460 after tax instead, and you are back to the tie.

What the numbers leave out

The calculator on this page is exact for the numbers you enter, but it simplifies a messy real world, and the simplifications matter. It uses one flat tax rate for each bracket, while real tax is marginal: the rate that matters is the rate on the last dollar, not your average rate, and a big Traditional withdrawal can push that last dollar into a higher bracket than you planned. It assumes a flat 7% return every year, while real returns vary and bad years early on hurt more than bad years late. None of that changes the core result: equal brackets tie, a higher later bracket favors the Roth, a lower later bracket favors the Traditional. But it does mean the real-world gap is usually a little different from the calculator’s gap, and usually in the Roth’s favor once forced withdrawals enter the picture.

The verdict

Pick the Roth if you expect your bracket to rise in retirement, if you are early in your career in a low bracket, if you can afford to max out the account after tax, or if you want the money to keep growing untouched with no required minimum distributions. At a 25% retirement bracket the Roth wins by $29,029.74, and maxed out it wins by $212,884.79. Pick the Traditional if you expect your bracket to fall in retirement, if you are in a high bracket now and want the deduction, or if the tax break today is what makes saving possible at all: at a 12% retirement bracket it wins by $96,765.81. If your bracket will not change, the accounts tie at $754,773.36 after tax, so choose on flexibility and run your own numbers in the Roth vs Traditional IRA calculator — and if you cannot decide, split between the two, because holding both hedges the bracket bet either way.
