How $300,000 Becomes $1,000 a Month
A portfolio yielding 4% generates $12,000 annually—$1,000 per month—without selling a single share. You own the same shares at year end that you started with. The cash just shows up.
Here's the math: $300,000 × 4% = $12,000 per year. At a 3% yield, you'd need $400,000 for the same $12,000. At 5%, only $240,000. Yield determines how much capital you need to hit your income target.
But yield isn't everything. A 10% yield often signals trouble—the stock price has collapsed because investors expect a dividend cut. The Dividend Aristocrats, companies that have raised dividends for 25+ consecutive years, currently average about 2.1% yield. Lower yield, but growing every year.
$100,000 at 2.5% vs. 5%: Which Wins After 15 Years?
Portfolio A: 2.5% yield, 8% annual dividend growth, dividends reinvested.
Portfolio B: 5% yield, 1% annual dividend growth, dividends reinvested.
Year 1 income: A generates $2,500. B generates $5,000. Easy win for B.
Year 15 income: A generates approximately $11,800. B generates approximately $6,700.
The dividend growth stock overtook the high-yield stock around year 9. By year 15, it pays 76% more annual income despite starting at half the yield. If you have a decade or more, growth usually beats current yield. If you need income next year, high yield wins short-term.
What Changes the Outcome
- Portfolio size: The math is simple—double the portfolio, double the income. At 4% yield, every additional $25,000 adds $1,000 per year in dividends.
- Dividend yield: Higher yields mean less capital needed, but often more risk. Sustainable yields typically range from 2-5%. Above 6-7%, investigate why the yield is so high.
- Dividend growth rate: A 7% annual increase doubles your income in about 10 years. Companies like Dividend Aristocrats have raised dividends through recessions and market crashes.
- Reinvestment: Reinvesting dividends during accumulation buys more shares, which pay more dividends, which buy more shares. This compounding accelerates income growth dramatically over 15-20 years.
- Concentration risk: If one stock represents 30% of your dividend income and it cuts its dividend, you lose 30% of your cash flow. Spread across 20-30 holdings or use dividend ETFs.
How to Run the Numbers
1. Enter each holding: ticker, shares, current price, and annual dividend per share.
2. Set your target annual income. Common goals: $12,000/year ($1,000/month), $24,000/year ($2,000/month), or whatever covers specific expenses like rent or utilities.
3. Choose a dividend growth rate. Use 3-5% for conservative estimates, 5-8% for growth-focused portfolios.
4. Toggle dividend reinvestment on if you're accumulating, off if you're taking cash.
5. Set your projection timeline—10-30 years is typical for retirement planning.

Method & Assumptions
This planner uses constant growth rate projections. Real dividends aren't constant—companies raise them, freeze them, and occasionally cut them. The 2020 pandemic saw many dividend suspensions. The projections here are educational estimates, not predictions.
Reinvestment is modeled by buying fractional shares at the current blended yield. Real DRIP programs may have timing differences, and actual yields at purchase time will vary.
Tax treatment depends on whether dividends are qualified (taxed at capital gains rates: 0%, 15%, or 20%) or ordinary (taxed at your income rate up to 37%). REIT and MLP dividends are usually ordinary income. The optional tax rate input provides a rough estimate, not precise tax planning.
