How Big a Portfolio to Generate $12,000 Monthly?

A monthly income of $12,000 — $144,000 annually — is more than double the U.S. per capita disposable personal income of $68,391 reported for Q1 2026. Replacing a paycheck with portfolio income is a math problem.

How to Calculate Required Portfolio Size

The formula is simple: divide the desired annual income by the expected annual yield. For example:

• At 4% yield, you need $3.6 million.
• At 5% yield, you need $2.88 million.
• At 6% yield, you need $2.4 million.

Higher yields reduce the required portfolio size but often come with higher risk.

Key Factors

• Asset Type: High-dividend stocks may offer 3-6% yields, while government bonds typically yield less.
• Inflation: Returns must outpace inflation to maintain purchasing power.
• Taxes: Investment income may be taxed, reducing net income.
• Risk: Higher yields often involve greater risk, such as market volatility or dividend cuts.

Practical Examples

To achieve $12,000 monthly:

• At 4% yield: $3,600,000 portfolio.
• At 5% yield: $2,880,000 portfolio.
• At 6% yield: $2,400,000 portfolio.

What This Means for Investors

There is no one-size-fits-all answer. The required portfolio size depends on your investment goals, risk tolerance, and time horizon. Consulting a financial advisor is recommended to develop a suitable strategy.
