House, kids, college and retirement all compete for the same paycheck. Here is how the ETF mix usually shifts between 35 and 49, when bonds start to come in, and how to spread one plan across a 401(k), an IRA and a taxable account.

If retirement is 15–30 years away, the ETFs that fit are mostly the same broad index funds as in your 20s: a US total-market or S&P 500 fund (VTI, VOO, SPYM), an international fund (VXUS, IXUS) and, from around 40, a growing slice of a core bond fund (BND, AGG). The funds rarely need to change. The mix and the account each one sits in do.
Scope: US households in peak earning years with a workplace plan, IRAs and often a taxable account. Not covered: mortgage payoff vs investing, insurance, 529 plan rules, or individual stocks. Hypothetical illustrations here are not advice for everyone your age. For the full map by age and role, start at the retirement ETF hub.
Sort every goal by when you need the money, then match the investment to that date. A down payment in two years and retirement in 25 years should not share one stock-heavy portfolio.
| Goal (as of Oct 2026) | When the money is needed | Typical home for it | Why |
|---|---|---|---|
| Emergency fund | Any time | Savings, money market or a T-bill ETF (SGOV, BIL) | Must be there in a bad month |
| House down payment | 1–3 years | T-bills, short Treasuries (VGSH) | A stock drop can’t be waited out |
| College | Depends on the child’s age | Stocks shrinking toward bonds as the date nears | Same logic as a glide path, shorter |
| Retirement | 15–30 years | Broad stock ETFs, bonds growing from ~40 | Time to recover from crashes |
A common benchmark for retirement progress is Fidelity’s: save at least 1× your salary by 30, 3× by 40 and 6× by 50, assuming 15% saved a year from age 25 (Fidelity). It is a rough guide, not a pass or fail. For the college side, see how much college money should stay in stocks.
Most published glide paths start around 40 and move slowly. Vanguard holds about 90% stocks early on and says that from 40, “We start to gradually reduce stock exposure,” reaching 50% at 65 and a final 30% stocks and 70% bonds at 72 (Vanguard glide path). Its real funds show what that means today:
| Vanguard target-date trust (Sep 30, 2026) | Designed to retire in | Stocks | Bonds | Rough age today, if retiring at 65 |
|---|---|---|---|---|
| Target Retirement 2050 Trust | 2048–2052 | 89.6% | 9.8% | about 39–43 |
| Target Retirement 2045 Trust | 2043–2047 | 82.0% | 17.4% | about 44–48 |
| Glide path at 65 | at retirement | 50% | 50% | 65 |
| Vanguard target-date trust (Sep 30, 2026) | Target Retirement 2050 Trust | Target Retirement 2045 Trust | Glide path at 65 |
|---|---|---|---|
| Designed to retire in | 2048–2052 | 2043–2047 | at retirement |
| Stocks | 89.6% | 82.0% | 50% |
| Bonds | 9.8% | 17.4% | 50% |
| Rough age today, if retiring at 65 | about 39–43 | about 44–48 | 65 |
Short-term reserves make up the rest. Inside the 2045 trust, the stocks are split about 60/40 between US and international funds, and the bonds include an international bond fund (Vanguard 2045 Trust, Vanguard 2050 Trust).
Why gradual: bonds softened losses but did not remove them. In 2022, BND lost 12.95% while VTI lost 19.51% (Exent market data, calendar-year total returns). A bond slice built over 25 years spreads out the risk of buying all of it at the wrong rate. How each bond fund behaves is in BND vs AGG and is the 60/40 portfolio dead?
Set one target mix for the household, then decide which account holds which piece. Each account does not need to be balanced on its own. Vanguard’s research found that asset location “can add up to about 0.3% annually in after-tax returns” when balances are meaningful in both taxable and tax-advantaged accounts, and its rule is “Place taxable bonds in tax-advantaged accounts first” (Vanguard, 2026). Broad stock index funds are the usual fit for a taxable account (Vanguard).
Limits from the IRS (IR-2025-111, Rev. Proc. 2025-19). Backdoor and mega-backdoor Roth steps are in where to invest after maxing your 401(k); fund choices by account in best ETFs for a Roth IRA and tax-efficient ETFs for a taxable account. Two incomes and two workplace plans: retirement ETFs for couples.
Hypothetical illustration, not advice for everyone your age. A household at 42 has $300,000: $190,000 in a 401(k), $50,000 in Roth IRAs and $60,000 in a taxable account. Target: 80% stocks and 20% bonds, close to Vanguard’s 2045 trust, with 70% of the stocks in the US and 30% abroad (Vanguard found 30–40% international gave “more than 95% of the benefit” of full diversification, Vanguard; more in international ETFs for retirement).
| Account | Balance | US stocks | International stocks | Bonds |
|---|---|---|---|---|
| 401(k) | $190,000 | $130,000 (plan S&P 500 or total-market index) | — | $60,000 (plan bond index) |
| Roth IRAs | $50,000 | — | $50,000 (VXUS) | — |
| Taxable | $60,000 | $38,000 (VTI) | $22,000 (VXUS) | — |
| Household total | $300,000 | $168,000 (56%) | $72,000 (24%) | $60,000 (20%) |
The arithmetic: stocks = 80% × $300,000 = $240,000; US = 70% × $240,000 = $168,000; international = $72,000; bonds = $60,000. All of the bonds fit inside the 401(k), so none of their interest is taxed each year. Next year’s rebalance happens inside the 401(k), where moving money between funds does not create a tax bill. Each year the bond target might rise a point or two, following a glide path like Vanguard’s. How to do the rebalance itself: calendar vs threshold rebalancing.
No. Twenty years of steady saving still compounds, and higher limits open at 50. Illustrative only: $1,500 a month, invested from age 45.
| Assumed return a year | Saving to 65 (20 years) | Saving to 67 (22 years) | Your own contributions (20 years) |
|---|---|---|---|
| 4% | $545,763 | $627,685 | $360,000 |
| 6% | $680,158 | $802,314 | $360,000 |
Exent calculation, illustrative, not a forecast: future value = monthly amount × ((1 + i)^n − 1) ÷ i, with i the monthly rate. At 4%, i = (1.04)^(1/12) − 1 = 0.3274% and n = 240 months. Two extra working years add roughly $80,000–$120,000 in this example.
Catch-up thinking before 50 means raising the savings rate with every raise. From 50, the 2026 IRS limits add an $8,000 401(k) catch-up ($32,500 total), $11,250 instead for ages 60–63, and an IRA limit of $8,600. A deeper plan for a late start is in I’m 49 with $80,000 saved and how much you should have by 50.
Adding bonds slowly from 40 is a default, and it misfits in three common cases:
Limitations. Glide paths are one provider’s view, and others differ. Tax rules are for 2026 and change; the IRS publishes 2027 limits around mid-November 2026. Past fund returns are not forecasts. A fee-only planner can weigh pensions, equity compensation and tax brackets.
In your 30s and 40s the plan is usually settled; the test is a rough quarter right before a rebalance. Exent is our product: Market intel puts the day’s market risk and macro news in one place, so you rebalance with context rather than headlines. It does not pick your ETFs, tell you when to trade or guarantee better results.
There’s no single number. Vanguard’s glide path holds about 90% stocks and 10% bonds until 40, and its 2045 target-date trust, for people about 44–48, held 17% bonds on September 30, 2026. Rules like 110 minus your age suggest about 30% bonds at 40.
No. Illustrative: $1,500 a month from 45 to 65 is about $546,000 at an assumed 4% a year, and from 50 the 2026 limits add an $8,000 401(k) catch-up.
Fidelity’s guideline is about 3× your salary by 40 and 6× by 50, assuming you saved 15% a year from 25. It is a rough benchmark, not a pass or fail.
Many people keep at least the employer match going, because skipping it gives up free money, and save the down payment separately in T-bills or savings. The right split depends on your timeline and other savings.
Vanguard’s research says to place taxable bonds in tax-advantaged accounts first, because their interest is taxed as ordinary income. Broad stock ETFs are usually the better fit for a taxable account.
In 2026, direct contributions phase out at $242,000–$252,000 of income for joint filers and $153,000–$168,000 for single filers. Above that, some people use a backdoor Roth, which has pro-rata tax rules.
Usually not. The same broad stock and bond index funds work; the bond share and the account each fund sits in change.
