How to calculate dividend income
Your yearly dividend income is your invested amount multiplied by the dividend yield. Then take off the tax on dividends to see what lands in your account.
You have $10,000 in dividend stocks with a 4% yield, and 15% tax is withheld.
- Before tax: $10,000 × 4% = $400 a year
- After tax: $400 × 0.85 = $340 a year
- That is about $28 a month
Most companies pay quarterly, so in practice you get about $85 four times a year. The monthly number is an average, useful for comparing with your bills.
How the growth projection works
The second part of the calculator shows how your income could grow. It runs year by year:
- Add every month – new money you invest, bought at that year's share price.
- Dividend growth – how much companies raise their dividend each year. Long-time dividend growers have often raised by 5–7% a year, but there is no guarantee.
- Share price growth – how much the share price rises each year. This affects the portfolio value and how many shares your new money buys.
- Reinvest dividends (DRIP) – dividends after tax are used to buy more shares, which then pay dividends too.
Yield on cost is your yearly dividend divided by everything you put in. It shows how dividend growth makes your original money work harder over time.
How much do you need for $1,000 a month?
Divide a year of income by the after-tax yield. With a 4% yield and 15% tax, the after-tax yield is 3.4%:
| Monthly income goal | Needed at 3% yield | Needed at 4% yield | Needed at 6% yield |
|---|---|---|---|
| $500 | $235,294 | $176,471 | $117,647 |
| $1,000 | $470,588 | $352,941 | $235,294 |
| $2,000 | $941,176 | $705,882 | $470,588 |
With 15% dividend tax. A very high yield can be a warning sign: it sometimes means the market expects the dividend to be cut.
Frequently asked questions
How do I calculate dividend income?
Multiply the amount invested by the dividend yield, subtract the dividend tax, and divide by 12 for a monthly average.
Where do I find the dividend yield?
Most broker apps and finance sites show it next to the share price. For an ETF, use its distribution yield. For your own portfolio, a weighted average across your holdings works well.
What tax rate should I use?
It depends on where you live and where the company is. US stocks often have 15% withheld for investors in countries with a tax treaty, and 30% without one. Your home country may tax dividends again. Check your local rules.
What is DRIP?
A dividend reinvestment plan: instead of taking dividends as cash, you use them to buy more shares. Those shares pay dividends too, so the income compounds.
Is the projection guaranteed?
No. Companies can cut or stop dividends, and share prices go up and down. The projection assumes steady growth to show what is possible, not what will happen.
