Dividend Income Goal Calculator: How Much Do You Need to Invest?
Work backwards from the monthly dividend income you want to the portfolio size required to produce it — after withholding tax.
Calculate the capital you need
How the calculation works
A portfolio produces gross annual income of capital × yield. After withholding tax at rate t, you keep capital × yield × (1 − t). Setting that equal to twelve times your monthly target and solving for capital gives the formula above. The monthly saving estimate then uses the standard future-value-of-a-series formula: it finds the fixed monthly payment whose compounded value equals the required capital after the number of years you entered.
Worked example
Target: $1,000 per month, yield 3.5%, withholding tax 10%. Annual net income needed is $12,000. Each dollar invested returns 0.035 × 0.90 = $0.0315 net per year, so the capital required is 12,000 ÷ 0.0315 = $380,952. Saving towards that over 20 years at an assumed 9% annual return requires roughly $570 per month. Change any assumption and the answer changes a lot — try a 3.0% yield to see a more conservative target.
Common mistakes when setting a dividend goal
First, mixing gross and net figures: a headline yield is gross, your bank account sees net. Second, treating a quarterly payer as monthly income without a buffer. Third, assuming today's yield lasts for decades. Re-run this calculator once a year with fresh figures, and cross-check the income side with the SCHD dividend calculator.
Frequently asked questions
How much do I need invested to get $1,000 a month in dividends?
At a 3.5% yield with no withholding tax, about $342,857. With 10% withholding tax, about $380,952, because part of each payment is withheld before it reaches you. The exact figure depends entirely on the yield you assume.
Why does withholding tax change the amount so much?
Because the tax is taken from every payment. To receive the same net income, the portfolio must generate more gross income, which means a larger portfolio at the same yield.
What yield should I assume?
Use the current yield of the fund or portfolio you actually plan to hold, and consider testing a lower yield as a stress case. Yields move with prices and dividend policies, so a single point estimate is fragile.
Does this include dividend growth?
No. This page works out the portfolio size needed at today's yield. Growth would reduce the time needed to get there, which the monthly-contribution result approximates through your assumed investment return.
Is a high yield always better?
No. A very high yield can signal a falling share price or an unsustainable payout. This calculator does arithmetic only; it does not judge whether a yield is safe.
