Vanguard LifeStrategy Growth (80/20)
Where it stands today
Our calculation, 1926-07 – 2026-09
Growth of $10,000
Where it came from
The Growth fund (now LifeStrategy 80/20; ticker VASGX) is the most equity-heavy member of the four-fund series (the 20/80 Income fund is the most conservative). Its objective is capital appreciation with some current income, and the fact sheet describes it as a fixed formula of about 80 % stocks and 20 % bonds.
The Vanguard LifeStrategy funds were launched on 30 September 1994 as a set of four ready-made balanced portfolios (Income, Conservative Growth, Moderate Growth and Growth), each a fund of funds that holds other Vanguard funds in fixed target proportions. The fund documents give 30 September 1994 as the inception date for all of them, and SEC filings place them in the Vanguard STAR Funds trust. I did not find a Vanguard statement explaining why the series was created in 1994 or who designed it; the motive below is therefore described only from what the documents show, not from a stated rationale.
For the first seventeen years the portfolios were not pure index mixes. The 2008 prospectus lists, for each of the three funds, a 25 % slot in the Vanguard Asset Allocation Fund, an actively tilted fund that could move between stocks, bonds and cash. Because of that slot the real stock/bond split of a LifeStrategy fund could differ from its label and could not be predicted exactly. In early October 2011 Vanguard announced that the Asset Allocation Fund would be removed and expense ratios lowered; the funds became static mixes of index funds, with the stock part split roughly 70 % US / 30 % international and the bond part held in the Total Bond Market index fund.
Two later changes widened the international share. In 2013 the boards approved moving part of each fund's bond exposure from US bonds into the currency-hedged Total International Bond Index Fund (a supplement shows Growth moving from 20 % US bonds to 16 % US plus 4 % international, i.e. a fifth of the bond sleeve); the semi-annual report says this was added in May 2013. In 2015 the boards raised the international share of the stock sleeve from 30 % to 40 % and the international share of the bond sleeve from 20 % to 30 %, with the total stock/bond split unchanged; the fund benchmarks switched to the new weights on 1 July 2015.
The funds were later renamed after their stock/bond split. By the 2026 documents the Growth fund is called LifeStrategy 80/20, Moderate Growth is 60/40 and Conservative Growth is 40/60 (the exact renaming date was not found). The 2026 fact sheets list the three funds with expense ratios of 0.10 % and total net assets of about 26.8, 24.1 and 11.0 billion dollars for 80/20, 60/40 and 40/60 respectively.

The idea
Give an ordinary investor a single fund with a fixed risk level (80 % stocks, 20 % bonds) built from broad low-cost index funds, with automatic rebalancing, so that the investor does not have to choose or trade the pieces. The Growth fund is the most stock-heavy fixed mix of the original four.
How people buy it
The fund itself (US mutual fund, Investor Shares; Vanguard fact sheet September 2026 gives expense ratio 0.10 %, which is the weighted cost of the underlying index funds). It holds Vanguard Total Stock Market Index, Total International Stock Index, Total Bond Market II Index and the (currency-hedged) Total International Bond Index funds. Do-it-yourself replication with the same four index funds or ETFs is possible. Non-US analogues exist under the same brand (UK LifeStrategy equity-percentage funds), but they have different compositions and are not modelled here.
Rebalancing as published
The fund rebalances automatically: it is a fixed-formula fund of funds that keeps the underlying funds at the target percentages; the fact sheet describes the allocation as a fixed formula (the exact trading frequency is not stated in the documents I read; a third-party profile mentions quarterly rebalancing, not verified in a Vanguard document).
Variants
- Era A (1994 to 2011, approximate, from the 2008 prospectus): 50 % Total Stock Market, 25 % Asset Allocation Fund, 15 % Total International Stock, 10 % Total Bond Market. The Asset Allocation Fund is an actively shifting stock/bond/cash fund, so for backtests it can be approximated as roughly 65 % US stocks / 35 % bonds, but that approximation is ours, not a published split.
- Era B (late 2011 to April 2013): 56 % US stocks, 24 % international stocks, 20 % Total Bond Market (stock sleeve 70/30 US/international).
- Era C (May 2013 to June 2015): 56 % US stocks, 24 % international stocks, 16 % US bonds, 4 % international bonds.
- Era D (since 1 July 2015): 48 / 32 / 14 / 6 (current).
- Benchmark history from the fact sheet footnote (the index composite, not the fund): 65 % Dow Jones US Total Stock Market, 20 % Barclays Aggregate, 15 % MSCI EAFE until 22 April 2005; the same with MSCI US Broad Market until 15 Dec 2010; 56 % US / 24 % MSCI ACWI ex USA IMI / 20 % Aggregate until 2 June 2013; 56/24/16/4 until 30 June 2015; 48/32/14/6 after.
Criticism
- Cost and tax: a 2011 review notes the funds are less tax-efficient than a self-built mix in a taxable account (less tax-loss harvesting, taxable bonds instead of municipal bonds, no asset-location choice) (Oblivious Investor).
- Until the autumn of 2011 the funds contained the Asset Allocation Fund, which one commentator called Vanguard's market-timing fund; this made the real stock/bond split unpredictable and was seen as a drawback (Oblivious Investor, Oct 2011).
- A fixed 80/20 mix does not reduce risk as the investor ages, unlike a target-date fund; Bogleheads note this as the main difference between LifeStrategy and Target Retirement funds.
- The bond sleeve now includes a currency-hedged foreign bond part (6 % of the fund), which is a change from a US-only bond sleeve and lowers the yield advantage a pure US sleeve would have; this is our observation, not a published criticism.

What we could not verify
- Why Vanguard created the series in 1994 and who designed it: no source found.
- Exact dates of the 2011 removal of the Asset Allocation Fund and the 2013 bond change: the Oblivious Investor article is dated 5 October 2011 and says changes would occur over the next few months; the semi-annual report says May 2013; I did not find the prospectus text with the effective dates.
- Calendar-year returns for 2008 and 2009 (crisis) were not found from a primary source.
- Era A weights come from the 2008 prospectus; the same 50/25/15/10 weights for 2000-2001 come from a search summary of the 2000 and 2001 filings and were not opened directly. Weights for 1994-1999 were not checked.
- Third-party sources (Bogleheads table) show the order of the 2015 change inconsistently; I followed Vanguard's own fact sheet footnote (56/24/16/4 before July 2015, 48/32/14/6 after).
- Renaming date from Growth to 80/20 not found.
