These 3 ETFs Shrink a 40-Tab Retirement Spreadsheet Down to One Page

You spent a career designing systems with margins, backups, and failure checks, so your retirement plan got the same treatment. At 66, you have a spreadsheet with a tab for every fund, rebalancing rules built into the formulas, and a dozen overlapping holdings you review every week. The plan works. It is also over-built. The same core jobs fit on a single page with three ETFs: iShares Core 80/20 Aggressive Allocation ETF (NYSEARCA:AOA), Vanguard Short-Term Treasury ETF (NASDAQ:VGSH) and Schwab U.S. Large-Cap Value ETF (NYSEARCA:SCHV).

Hidden Costs Buried in a 40-Tab Retirement Plan

Complexity carries costs that never show up on a statement. An S&P 500 fund, a total-market fund, and a large-cap growth fund often own the same companies, so your real diversification is thinner than the tab count suggests. Every extra fund adds another rebalancing calculation and another chance for a formula error to slip through.

The biggest risk is a plan only you can read. If you can’t manage it someday, your spouse or heirs inherit a plan they cannot easily follow.

AOA Replaces Your Allocation and Rebalancing Tabs

AOA is a fund of funds. As of July 31, 2026, about 45.7% sat in an iShares S&P 500 fund, 22.8% in international developed-market stocks, and 8.5% in emerging markets, with smaller portions in U.S. mid-caps and small-caps. Bonds fill out the rest, led by a U.S. bond fund at 16.1% and international bonds at 2.9%. The fund maintains that roughly 80/20 mix itself, so your domestic, international, bond, and rebalancing tabs collapse into one line.

AOA held about $3.19 billion in net assets. Its adjusted price rose 9.83% over the past year and 165.58% over 10 years. It pays quarterly, with trailing 12-month distributions of $2.11 per share yielding roughly 2.2% at the current price. iShares posts the current expense ratio on the fund page, so compare it with the combined fees of the funds it would replace.

The catch: the mix is fixed and leans heavily toward stocks. An 80% equity stake may be more aggressive than you want in your late 60s, which is exactly why the next fund matters.

VGSH Funds the Next Few Years of Withdrawals

VGSH holds short-dated U.S. Treasury bonds. Its expense ratio is 0.03%, or about $0.30 a year on every $1,000 invested. Distributions come monthly, most recently $0.1889 per share on November 4, 2026, and trailing 12-month payouts of $2.18 equal roughly 3.8% at today’s price. Its adjusted price moved just 1.65% over the past year.

Investors who use VGSH as a withdrawal reserve can drop the money market, CD ladder, and short-bond tabs. If you want to see how a reserve like this fits into a broader paycheck-style setup, with the mix, payout calendar, and withdrawal order worked out, we outlined the whole method here: The Paycheck Portfolio Method.

The catch: the yield moves with short-term rates. In February 2022, the monthly payout was only $0.0168. Growth is minimal, too, at about 10.56% over five years.

SCHV Keeps One Deliberate Choice in Your Hands

SCHV is optional, built for the reader who wants to keep one decision of their own. It tracks large U.S. value stocks spread across financials, energy, healthcare, industrials, and consumer staples. It held about $15.67 billion in net assets as of August 31, 2026, and its adjusted price rose 21.51% over the past year. Quarterly payouts totaled $0.63 per share over 12 months, about 1.8% at the current price. SCHV replaces your dividend-stock and value-fund tabs.

The catch: value stocks can trail growth stocks for long periods. SCHV also overlaps with AOA’s S&P 500 portion, so a modest allocation limits duplication.

Consolidate Without Triggering a Surprise Tax Bill

Check overlap first. Pull the top holdings of every fund you own and flag duplicates before you sell anything.

Then look at where each fund sits. The IRS notes that its rules on investment gains “do not apply to investments held in individual retirement arrangements (IRAs), section 401(k) plans, and other qualified retirement plans,” so trades inside an IRA don’t create capital gains. Selling in a taxable account can, and your broker reports those sales on Form 1099-B. Consolidating IRAs also simplifies withdrawals. You calculate each IRA’s required minimum distribution separately but “can withdraw the total amount from one or more of the IRAs.”

Trade-Off Every Engineer Should Weigh

Simplicity has a price. You give up the fine control your spreadsheet provides, and AOA’s fixed 80/20 mix may not match your risk tolerance unless you hold enough VGSH alongside it. If you enjoy tuning sector weights, three funds will feel restrictive.

But a good design is one someone else can maintain. That means one growth fund, one withdrawal reserve, and one deliberate factor allocation on a single page your spouse or heirs can read, run, and trust.
