How to use the dividend calculator
- Enter your starting investment and how much you'll invest each month.
- Enter the dividend yield, the expected dividend growth and share price growth per year.
- Choose whether to reinvest dividends (DRIP) and the tax rate on dividends.
- Set a monthly income goal to see how much you'd need invested.
Reinvesting vs taking cash
Same example over 20 years ($130,000 invested in total):
| Portfolio value | Dividend income per year | |
|---|---|---|
| Reinvest dividends (DRIP) | about $312,000 | about $11,100 |
| Take dividends as cash | about $204,000 | about $7,300 |
Reinvesting buys more shares, which pay more dividends, which buy more shares. It's compounding in action. Taking the cash gave about $64,000 of income along the way, but a smaller portfolio at the end.
How much do you need for a dividend income?
At a 3.5% yield and 15% tax:
| Monthly income goal | Invested needed |
|---|---|
| $500 | about $202,000 |
| $1,000 | about $403,000 |
| $2,000 | about $807,000 |
| $3,000 | about $1.21 million |
Without tax (for example inside an IRA), the amounts are about 15% lower.
Yield, growth and safety
- Yield is the dividend as a percentage of the share price. A very high yield can mean the price has fallen because investors expect a dividend cut.
- Dividend growth matters as much as yield: a 2.5% yield growing 8% a year can overtake a 5% yield that never grows.
- Diversify: broad dividend ETFs and index funds spread the risk across hundreds of companies.
- Total return counts too: price growth plus dividends.
Dividends and early retirement
Some people aim to live on dividends alone. A related approach is the 4% rule: withdraw 4% of a diversified portfolio each year. The FIRE calculator works out the portfolio you'd need for your spending, and the how long will my money last calculator tests withdrawals. For tax-free dividends, consider holding them in a Roth IRA; see the Roth IRA calculator.
For growth with regular deposits at a single return rate, use the compound interest calculator.
