Dividend Calculator
Turn an investment amount, share price and dividend per share into yearly and monthly income, plus an optional reinvestment growth projection.
Enter what you’re investing, the share price and the annual dividend per share. You get the yearly and monthly income it throws off — and, if you add a growth rate and a horizon, how that income compounds with reinvestment.填入你的投资金额、股价与每股年度股息，即可得到它产生的年度与月度收入；再填入增长率与年限，还能看到收入在股息再投资下如何复利增长。
Fill in the amount, share price and dividend per share to see the income.填入金额、股价与每股股息即可查看收入。

Your annual dividend income is simply the number of shares you own times the dividend per share. Shares come from your amount invested divided by the share price; the yield is the dividend per share as a percent of that price. Divide the yearly income by twelve for a monthly figure — though most companies actually pay quarterly.你的年度股息收入，就是持有股数乘以每股股息。股数等于投资金额除以股价；股息率则是每股股息占股价的百分比。把年度收入除以十二即得月度数字——尽管多数公司实际上按季度派息。
01The formula公式
Annual income = Shares × Dividend per share年度收入 = 股数 × 每股股息
Dividend yield = 100 × Dividend per share ÷ Share price股息率 = 100 × 每股股息 ÷ 股价
Monthly income = Annual income ÷ 12月度收入 = 年度收入 ÷ 12
Add a growth rate and a horizon and the projection compounds. If you reinvest, each year’s dividends buy more shares (we hold the price constant to isolate the dividend effect), and the dividend per share itself grows by your growth rate — two engines turning together. If you take the cash, the share count stays put and only the per-share dividend grows.再填入增长率与年限，测算便开始复利。若你选择再投资，每年的股息会买入更多股份（我们保持股价不变，以单独呈现股息效应），同时每股股息本身也按你的增长率提高——两台引擎同时运转。若你领取现金，股数保持不变，仅每股股息增长。
02A worked example一个算例
Suppose a trader puts $10,000 into a stock at $50.00 a share that pays $2.00 in annual dividends per share.假设一位交易者以每股 $50.00 投入 $10,000 于一只每股年派息 $2.00 的股票。
- Shares = 10,000 ÷ 50 = 200股数 = 10,000 ÷ 50 = 200
- Annual income = 200 × 2 = $400年度收入 = 200 × 2 = $400
- Dividend yield = 100 × 2 ÷ 50 = 4.00%股息率 = 100 × 2 ÷ 50 = 4.00%
- Monthly income = 400 ÷ 12 = $33.33月度收入 = 400 ÷ 12 = $33.33
That $400 is the income at today’s dividend. Hold for a decade with the dividend growing 6% a year and reinvested, and both the share count and the per-share payout climb — the yearly income can end up well above where it started, which is the quiet appeal of dividend growth.这 $400 是按当前股息计的收入。若持有十年、股息每年增长 6% 并再投资，股数与每股派息都会攀升——年度收入最终可远高于起点，这正是股息增长的静默魅力。
03The common trap常见陷阱
A very high yield is often a warning, not a bargain. Yield is the dividend divided by the price — so when a stock’s price falls hard, the yield mechanically spikes even as the business weakens. If the company then cuts the dividend, the income you were counting on shrinks and the price can fall further. A yield far above a company’s peers deserves a look at why before it deserves your capital.极高的股息率往往是警讯，而非便宜货。股息率等于股息除以价格——所以当股价大跌时，即便基本面在恶化，股息率也会机械性地飙升。若公司随后削减股息，你所依赖的收入会缩水，价格还可能进一步下跌。远高于同业的股息率，先要弄清为何如此，再谈是否投入资本。
04Where this breaks它的局限
The base income math is exact; the projection is a clean model, not a forecast. A few honest limits:基础收入的算法是精确的；测算则是一个干净的模型，而非预测。几点诚实的局限：
- Prices don’t stand still. The projection holds the share price constant to isolate the dividend. In reality the share price moves, which changes what reinvested dividends buy and the total value of the holding.价格并非静止。测算为单独呈现股息而保持股价不变。现实中股价会波动，从而改变再投资股息所能买入的份额，以及持仓的总价值。
- Dividends aren’t promised. A dividend is declared by the board each period, not guaranteed. Growth rates are assumptions — payouts can be frozen or cut, and a steady growth rate is a smooth line drawn over a bumpy reality.股息并非承诺。股息由董事会每期决议，而非保证。增长率是假设——派息可能被冻结或削减，恒定的增长率只是画在崎岖现实之上的一条平滑曲线。
- Taxes and fractional shares. This ignores dividend taxes, which reduce what you actually reinvest, and assumes fractional shares can be bought. Both shift the real outcome.税收与零股。此处忽略了会减少你实际再投资金额的股息税，并假设可买入零股。二者都会改变真实结果。
Income today is arithmetic; income in ten years is an assumption. Treat the yearly figure as fact and the projection as a scenario.当下的收入是算术；十年后的收入是假设。把年度数字当作事实，把测算当作情景。
