Putting $25,000 into the Vanguard Morningstar Total Stock Market ETF (NYSEARCA:VTI) on day one gets a saver to $1 million almost as fast as adding $250 more a month for roughly twenty-five years.
It does so at about a third of the cost. That makes VTI a strong core holding, because VTI advantages early money far more than late money.
Longtime holders may see a new name. Since July 2026, the fund has tracked the Morningstar US Total Market Index, the renamed former CRSP index, with the same strategy.
Large, mid, and small U.S. companies fill the fund, which charges 0.03% and yields 1.1%. It holds $689 billion in its ETF share class and $2.32 trillion overall. For a saver chasing seven figures, the question is which extra money buys more speed per dollar: a one-time windfall or a bigger monthly contribution.
How $25,000 Up Front Nearly Matches a $250 Monthly Raise
The model uses Vanguard’s Total Stock Market Index mutual fund (VTSMX) from May 1992 and VTI from July 2001. Dividends are reinvested, with deposits at each month’s start.
The pre-2001 years use the mutual fund, which charged a higher fee. The series’ 11% annual return therefore slightly understates VTI.
