Roth IRA Asset Allocation: How to Visualize Your Mix

A Roth IRA is the most tax-advantaged account most Americans can access. Every dollar of growth inside a Roth is tax-free forever. That single fact should drive how you allocate your Roth — and it is why putting bonds in a Roth is usually a mistake.

The Roth IRA allocation principle

Tax-free growth is the entire point of a Roth. The math says: put your highest-expected-return assets here so the tax-free benefit applies to the biggest gains.

Asset	Expected return	Tax efficiency	Roth fit
US stocks (index)	7-10%	Medium	Excellent
Small caps	8-11%	Low	Excellent
International stocks	6-9%	Low	Great
Emerging markets	7-10%	Low	Great
REITs	6-9%	Very low	Great
Bonds	3-5%	Low	Poor

The lower the natural tax efficiency of an asset, the better it fits in a Roth. REITs, small caps, and international stocks all benefit dramatically from being in a Roth because they generate a lot of taxable distributions in regular accounts.

Sample Roth IRA portfolios

Aggressive (20s-40s)

Holding	Ticker	%
Total US Stock Market	VTI	60%
Total International Stock	VXUS	25%
Small Cap Value	AVUV / VBR	10%
Emerging Markets	VWO	5%

100% stocks. Maximum growth potential. Tax-free for decades.

Moderate (40s-50s)

Holding	Ticker	%
Total US Stock Market	VTI	55%
Total International Stock	VXUS	25%
Small Cap Value	AVUV	10%
REITs	VNQ	10%

Still 100% stocks (including REITs). Bonds live in your 401(k).

Pre-retirement (50s-60s)

Holding	Ticker	%
Total US Stock Market	VTI	60%
Total International Stock	VXUS	20%
REITs	VNQ	10%
Dividend stocks	SCHD	10%

Still aggressive. Roths are best left to grow as long as possible — there are no required minimum distributions during your lifetime.

Tax location strategy

Most investors should think of their accounts as ONE portfolio, then place each asset where it gets the best tax treatment:

Account	Best for	Reason
Roth IRA	Stocks, REITs, small caps	Tax-free growth on highest returns
Traditional IRA / 401(k)	Bonds, dividend stocks	Tax-deferred on income-heavy assets
Taxable brokerage	Tax-efficient ETFs (VTI, VXUS), municipal bonds	Capital gains treatment + foreign tax credit

This is called "tax location" or "asset location." Two portfolios with identical allocations but different tax locations can have dramatically different after-tax returns over decades.

Why bonds in a Roth is usually wrong

Imagine $10,000 over 30 years:

• Bonds at 4% → $32,000 (gain of $22,000)
• Stocks at 8% → $100,000 (gain of $90,000)

If both are in a Roth, the tax-free benefit applies to the gain. The bonds save you tax on $22K. The stocks save you tax on $90K. Same $10K of starting capital, but the stocks make 4x better use of the Roth's tax shelter.

If you hold $10K of bonds and $10K of stocks, putting the stocks in the Roth and the bonds in the 401(k) usually wins by tens of thousands of dollars over decades.

Roth IRA contribution rules (2026)

• Annual limit: $7,000 ($8,000 if age 50+)
• Income phase-out for single filers: $146,000 - $161,000 (modified AGI)
• Income phase-out for married filing jointly: $230,000 - $240,000
• No required minimum distributions during your lifetime
• Contributions can be withdrawn anytime tax/penalty-free

The "no RMDs" feature is huge. Unlike 401(k)s and traditional IRAs, a Roth can grow tax-free for as long as you live. Some retirees never touch their Roths and pass them to heirs.

Backdoor Roth for high earners

If your income exceeds the phase-out, you can still contribute via a backdoor Roth: contribute to a non-deductible traditional IRA, then convert to Roth. The conversion is taxable on any pre-tax basis you have. The strategy is legal but slightly complex — talk to a tax pro the first time.

Visualize your Roth allocation

Use the portfolio visualizer to enter your Roth holdings as a pie chart. Most should show 100% stocks (across various flavors). If you see a big bond slice, ask whether those bonds would do more for you in a different account type.
