Dividend Income Calculator
Estimate the annual and monthly income from a dividend-paying portfolio, and see how reinvesting can grow that income over time.
Default 3.36% is the SPDR Straits Times Index ETF (ES3) yield — illustrative, not a government figure. Adjust to your holdings.
Reinvesting buys more units each year, so the dividend grows; taking cash keeps income flat.

Estimates only. Dividend yields are not guaranteed and can fall, be cut or rise; reinvestment assumes dividends buy more units at the same yield. Figures ignore tax and fees (Singapore does not tax dividends for individuals).

How dividend income works
A dividend is a share of a company’s profits paid out to shareholders, usually quarterly or semi-annually. The dividend yield expresses those payments as a percentage of the portfolio’s value, so a higher yield or a larger portfolio means more income. This tool turns your portfolio value and yield into a yearly and monthly income estimate.
The default yield is the Straits Times Index ETF’s trailing yield, a convenient benchmark for a broad Singapore equity holding. It is illustrative only — real yields move with prices and payout decisions, and your own mix of REITs, blue chips, bonds or global funds will differ.
Reinvest or take the cash?
Reinvesting dividends buys more units each year, compounding your future income — useful while you are still building wealth. Taking dividends as cash keeps the portfolio and income flat, which suits retirees living off the payouts. To model price growth on top of dividends, pair this with the compound interest and portfolio growth calculators.
Frequently asked questions
How is dividend income calculated?
Annual dividend income is simply your portfolio value multiplied by its dividend yield. For example, $100,000 at a 3.36% yield pays about $3,360 a year, or roughly $280 a month. Divide the annual figure by 12 for a monthly estimate.
What dividend yield should I use?
It depends on what you hold. The default 3.36% is the trailing yield of the SPDR Straits Times Index ETF (ES3) — an illustrative, third-party figure, not a government statistic. REITs often yield more (around 5–7%), individual blue chips and bonds vary, so set the yield to match your own portfolio.
What does reinvesting dividends do?
When you reinvest, each year’s dividends buy more units, so the next year’s payout is calculated on a larger base — your income compounds over time. If you take dividends as cash instead, both the portfolio and the income stay flat (before any price growth).
Are dividends taxed in Singapore?
Dividends from Singapore-resident companies are generally tax-free for individuals under the one-tier system, and Singapore has no capital-gains tax. Foreign dividends may incur withholding tax at source (for example, US shares). This calculator shows gross figures and does not deduct any tax or fees.
