Roth vs Traditional

Decision framework (education, not advice)

Leans Roth

Leans Roth — higher expected future rates

If you expect to be in a higher tax situation in retirement than today, paying tax on contribution dollars now can look more attractive so qualified withdrawals stay tax-free.

Leans Roth

Leans Roth — tax-free withdrawals / fewer taxable RMDs

On this vignette Roth’s after-tax nest egg leads (≈ $708,455.90). Roth IRAs generally avoid lifetime RMDs for the original owner — a qualitative plus not quantified here.

Leans Traditional

Leans Traditional — year-1 cash-flow is binding

If funding $7,500 is tight, Traditional’s modeled year-1 tax savings (≈ $1,650.00 in TX; ≈ $2,347.50 in CA) leaves more spendable cash after the same contribution.

Leans Traditional

Leans Traditional — lower expected future rates

If you expect lower taxable income in retirement than today, the deduction now may outweigh tax-free withdrawals later — still verify eligibility and use today’s stand-in only as a teaching tool.

Either / both

Often either / both — diversify tax buckets

Many households hold both Roth and Traditional (or workplace equivalents) so future tax outcomes are not all-or-nothing. This hub compares pure paths on one vignette.

Either / both

Check eligibility before preferring a path

MAGI phase-outs and workplace coverage can force a different choice than the scoreboard alone suggests — confirm with IRS Pub 590-A.

Myths vs facts

“Roth and Traditional end with the same after-tax money if rates never change.”

On equal dollar contributions, Roth’s nest egg is after-tax dollars growing tax-free, while Traditional’s balance is pre-withdrawal. Applying today’s 13.17% stand-in, Roth ≈ $708,455.90 vs Traditional ≈ $615,152.26.

“Roth always saves tax in year one.”

Roth contributions are after-tax — year-1 tax savings is $0 vs a no-contribution baseline on this hub.

“Traditional never helps cash-flow.”

On $100,000 single TX, a $7,500 deductible contribution models about $1,650.00 more in year-1 tax savings (cash edge vs Roth after funding the same contribution).

“This predicts my future tax bracket.”

No — Traditional after-tax nest egg uses today’s effective income-tax rate as a stand-in only. Future brackets, RMDs, and other rules can change the result.

“California and Texas look the same for Traditional.”

State income tax can make the Traditional deduction worth more year-one in CA (≈ $2,347.50) than in TX (≈ $1,650.00) on this salary and contribution.

“A higher account balance always means a better path.”

Both paths share the same modeled balance (≈ $708,455.90). The useful compare is after-tax nest egg and year-1 cash-flow, not the pre-tax balance alone.

“I can ignore eligibility and just pick Roth or Traditional.”

MAGI phase-outs, workplace plan coverage, and filing status can limit Roth contributions or Traditional deductibility — confirm with IRS Pub 590-A before treating this vignette as your case.

Common mistakes

Treating shared balance as the winner

Both paths share ≈ $708,455.90 at retirement on the vignette. Compare after-tax nest egg and year-1 tax savings instead.

Assuming Roth cuts this year’s tax bill

Roth contributions are after-tax — year-1 tax savings vs a no-contribution baseline is $0 on this model.

Using the stand-in rate as a forecast

Today’s effective income-tax rate teaches the Traditional withdrawal haircut; it is not a prediction of your future bracket.

Ignoring state income tax on year-1 Traditional math

TX and CA can diverge materially on deductible-contribution tax savings even with the same salary and contribution.

Skipping eligibility and phase-outs

Scoreboards assume the contribution is allowed and (for Traditional) deductible — real MAGI tests may differ.

Mixing equal-contribution with equal-net experiments

Putting the same dollars into each IRA is not the same as equalizing take-home after funding. This hub only does the first.

Concepts

Equal contribution, different tax timing

Same dollars into the account each year; Roth pays tax up front, Traditional defers it.

Nest egg vs cash-flow scoreboards

Primary rank is after-tax nest egg; year-1 Traditional tax savings is a second lens for current cash-flow after equal contributions.

Stand-in rate, not a forecast

Today’s effective income-tax rate on $100,000 stands in for future Traditional withdrawal tax.

State income tax matters year-one

A deductible contribution can save more in CA than in TX because state tax amplifies the deduction.

Balance ≠ spendable nest egg

Shared pre-withdrawal balance can hide a large after-tax gap once Traditional withdrawals are taxed.

Eligibility is separate from vignette math

You can understand the tax-timing trade-off here and still need Pub 590-A for MAGI and workplace-coverage tests.

Planning notes (education, not advice)

Match the account to expected rates

If you expect higher rates later, Roth’s tax-free withdrawals can matter more; if lower, Traditional’s deduction may look better — this hub does not predict your path.

Watch eligibility and phase-outs

Income limits and workplace coverage can change deductibility or Roth contribution room.

Employer plans are separate

401(k) Roth vs Traditional can follow similar tax-timing logic but different limits — see the blog if you contribute at work.

Revisit when income or state changes

A raise, a move to a high-tax state, or retirement relocation can flip which scoreboard matters most.

Coordinate with Social Security and RMDs

Taxable Traditional withdrawals can interact with other retirement income; this hub excludes those interactions.

This is education, not advice

IRS pages and this hub do not replace a tax or financial professional.

How to use this profile

  1. Scan the nest-egg scoreboard. Compare after-tax nest egg first — Roth vs Traditional on the locked vignette.
  2. Check year-1 cash-flow. Traditional’s tax savings vs Roth’s $0 year-1 AGI cut — after the same contribution, Traditional leaves that much more cash.
  3. Read the stand-in disclosure. Today’s effective income-tax rate is not a forecast of future brackets.
  4. Walk the contribution ladder. See how nest egg and year-1 tax savings scale with annual contributions.
  5. Use the decision framework. Match your situation to the educational “leans Roth / leans Traditional” signals — not a personalized recommendation.
  6. Note common mistakes. Avoid confusing equal contributions with equal after-tax wealth, or treating the stand-in rate as a prophecy.
  7. Personalize. Run exact ages, returns, and salary in the Roth IRA and US paycheck calculators.

Cash-flow-constrained households

If funding the IRA squeezes the monthly budget, year-1 Traditional tax savings is the scoreboard to weigh carefully.

Glossary

Roth IRA
After-tax contributions; qualified withdrawals are generally tax-free (IRS Pub 590-A / 590-B).
Traditional IRA
Often deductible contributions that reduce AGI today; withdrawals generally taxed as ordinary income.
Year-1 tax savings
Lower income tax from a deductible Traditional contribution vs the same salary with no contribution (FICA unchanged). After funding the same IRA contribution, Traditional leaves about that much more spendable cash than Roth.
After-tax nest egg
Roth: full balance. Traditional: balance reduced by today’s effective income-tax rate stand-in for future withdrawal tax.
Effective income-tax rate (stand-in)
Federal + state income tax on the $100,000 baseline ÷ salary — FICA excluded from this rate.
Contribution limit (under 50)
$7,500 for 2026 Roth/Traditional IRA under age 50 (IRS; from the same limit table as the Roth IRA calculator).
Catch-up contribution (50+)
Extra $1,100 for 2026 when age 50+ (IRS limit table). This hub’s vignette uses the under-50 limit only.
Qualified withdrawal
Generally age 59½+ and a 5-year clock for Roth — details in IRS Pub 590-B; this hub assumes qualified treatment for the Roth nest egg.
AGI
Adjusted gross income — the starting point for many IRA deduction and eligibility tests. Deductible Traditional contributions can lower AGI.
MAGI
Modified AGI used for Roth contribution eligibility and Traditional deductibility tests. Phase-out ranges are published by the IRS and are not modeled on this hub.
RMD
Required minimum distribution — Traditional IRAs generally require lifetime RMDs; Roth IRAs generally do not during the original owner’s life. Not modeled here.
Equal-contribution vignette
Both paths put the same $7,500 into the account each year — isolating tax timing, not different savings rates.

What we exclude
