Dividend Income Calculator: How Much to Invest for $X a Month

How the portfolio size is worked out

A dividend yield is the yearly dividend as a percentage of the share price. To find the portfolio that produces a given income, divide the yearly income you want by the yield.

Portfolio needed = monthly income × 12 ÷ dividend yield

At a 3.5% yield, $1,000 a month takes about $343,000 invested. A broad US stock index fund yields much less, recently around 1 to 1.5%, so the same income would take $800,000 or more, while higher-yield dividend funds sit around 3 to 4%. Starting with $20,000 and adding $750 a month at a 7% total return, you would reach $343,000 in about 16 and a half years.

Dividends vs selling shares

Living on dividends feels safe because you never sell shares, but a dollar of dividend is not worth more than a dollar of growth. High-yield stocks can lag the wider market, and dividends can be cut when companies struggle. Many people combine dividends with a planned withdrawal rate instead; the withdrawal rate calculator shows that approach.

How the yield changes the target

The yield you assume moves the target a lot. For $1,000 a month, or $12,000 a year, you need about $600,000 at a 2% yield, $400,000 at 3%, $300,000 at 4% and $240,000 at 5%. Broad US stock index funds have yielded well under 2% in recent years, while dividend-focused funds often yield around 3% to 4%.

Chasing a very high yield to shrink the target carries risk, since unusually high yields often signal that the market expects a dividend cut. A realistic yield gives a more honest goal.
