Collecting $8,450 a month comes to $101,400 a year. Replacing that paycheck with investment income alone requires a specific amount of capital at each yield level. Fidelity’s retirement guidelines call for savings of 10x salary by age 67 to keep the same lifestyle. For this income, that works out to roughly $1,014,000.

Interest rates shape the comparison, since the 10-year Treasury yields 5.3%, its highest level in the past year. Consumer prices rose about 3% through August. Any yield above the Treasury rate comes with extra risk, and any income that stays flat loses buying power.

Conservative Tier Requires Close to $2.9 Million

At a 3.5% yield, $101,400 divided by 0.035 equals about $2,897,000. This tier includes dividend growth funds, broad-market income ETFs, and regulated utilities. Southern Company (NYSE:SO | SO Price Prediction) fits here with a yield near 3.6%, and its quarterly dividend has climbed from $0.70 in late 2023 to $0.76. Demand from data centers drove commercial kWh sales up 7% last quarter. This tier demands the most capital, though it also carries the lowest risk of an income cut.

Moderate Yields Cut the Bill to $1.69 Million

At 6%, $101,400 divided by 0.06 equals $1,690,000. This range includes net lease REITs, high-dividend drugmakers and covered call ETFs.

The recommendation begins with W. P. Carey (NYSE:WPC), which yields about 5.9% after raising its quarterly payout to $0.95. Rent escalators linked to inflation cover 48% of its base rent. The REIT did cut its dividend at the end of 2023, from a prior $1.071.

Pfizer (NYSE:PFE) yields about 6%, and its quarterly dividend is holding flat at $0.43. On the latest earnings call, the CEO said “the dividend will be maintained and eventually after the LOE period will start again growing it.” The tradeoff in this tier is slower dividend growth.

Aggressive Yields Drop the Requirement Below $1.1 Million

At 10%, $101,400 divided by 0.10 equals $1,014,000. At 13%, the requirement falls to $780,000. This tier includes business development companies, leveraged bond funds, and mortgage REITs.

Hercules Capital (NYSE:HTGC) yields about 9.4%. Net investment income includes its base dividend at 125%, but non-accrual loans rose from 1 to 2.

PIMCO Dynamic Income Fund (NYSE:PDI) pays $0.2205 a month, which is about 18.7% at a $14 share price. The shares have fallen about 17% over the past year. The high income here can come at the cost of principal.

How a Seven-Fund Mix Gets There

Holding Weight Yield
Fidelity High Dividend ETF 20% About 3% (typical)
Goldman Sachs S&P 500 Premium Income ETF 20% About 8% (typical)
W. P. Carey 15% 5.9%
PIMCO Dynamic Income 15% 18.7%
Hercules Capital 10% 9.4%
Southern Company 10% 3.6%
Pfizer 10% 6%

This blend yields about 7.8%, so it needs roughly $1.3 million to produce $8,450 a month. PIMCO Dynamic Income alone supplies about 36% of the income. Together, the two highest yielders supply about 48%.

Why the Lower Yield Can Pay More Later

Say $2.9 million earns 3.5% and the dividends grow 8% a year. Income would reach about $202,700 by year nine. Compare that with $1,014,000 earning a flat 10%. That portfolio still pays $101,400, while inflation of about 3% a year shrinks what the money buys. W. P. Carey’s payout has risen about 10% since late 2023, showing the effect of a moderate yield.

Steps Before Committing Capital

  1. Track actual spending. Social Security or a pension can shrink the amount the portfolio needs to cover, which can move the target into a lower-risk tier.
  2. Test the blend under stress. Remove income from PIMCO Dynamic Income and Hercules and check whether what is left covers essential bills.
  3. Model the taxes. REIT and BDC payouts are mostly taxed as ordinary income, while utility and drug company dividends often qualify for lower rates. Where each holding sits, in an IRA or a taxable account, changes how much of the $8,450 you keep.
