Vanguard High Dividend Yield ETF VYM

Reaching $9,650 a month in retirement income sounds like a fixed target, but the amount a couple actually needs invested swings by more than $2 million depending on which assets they choose and how those choices age over time.

Treasury bills near 4.5% sound like a no-brainer alternative to dividend stocks, but two overlooked risks quietly eat into that advantage in ways most retirees never calculate before locking in their income strategy.

Vanguard emphasizes broad diversification and lower costs, while Fidelity targets higher yields through concentrated tech exposure.
