What a dividend actually is
A is a cash payment a company sends to its shareholders — usually every quarter — out of the profits it earned that period. If you own 100 shares of a company that pays $1.00/year in dividends, that's $100 in cash landing in your brokerage account, split into four ~$25 payments.
Not every company pays one. Growth-obsessed companies like Alphabet, Amazon, and Tesla reinvest every dollar back into the business. Mature companies — Coca-Cola, Procter & Gamble, Chevron — pay a chunk of profits out to shareholders because they can't productively reinvest all of it. Those are the companies dividend investors hunt.
You invest $10,000 in SCHD, an ETF with a ~3.5% . In year one you'll receive about $350, paid quarterly (~$87/quarter). That's the income part.
But SCHD has raised its dividend ~12%/year for the last decade. So by year 10, that same $10k position (without adding a dollar) is throwing off roughly $1,100/year — an of ~11%. That's the growth part. Section 2 explains why this matters more than the current yield.
Two dates matter: the (must own before this to get paid) and the payment date (when cash actually hits). If you buy on or after the ex-div date, you miss that quarter — the seller pockets it.
The one number that separates good dividends from bad ones: the . Under 60% means the company keeps enough profit to keep growing. Over 100% means they're paying out more than they earn — usually right before a dividend cut. DPP's Ticker Research tab flags this automatically as part of its score.
Yield vs Yield-on-Cost — why one grows and the other doesn't
is the number every finance site shows on a stock's page. It's just: annual dividend ÷ current share price. If a stock trades at $100 and pays $3/year, its yield is 3%.
The problem: current yield tells you nothing about what you personally earn. It changes every second the price moves. The number that matters for a long-term investor is — annual dividend ÷ your purchase price. Unlike current yield, YoC only moves in one direction: up (as long as the company keeps raising its dividend).
| Year | Share price | Annual dividend | Current yield | Your YoC |
|---|---|---|---|---|
| 0 | $60 | $1.80 | 3.00% | 3.00% |
| 5 | $92 | $2.75 | 2.99% | 4.58% |
| 10 | $141 | $4.20 | 2.98% | 7.00% |
| 15 | $216 | $6.42 | 2.97% | 10.70% |
| 20 | $331 | $9.81 | 2.96% | 16.35% |
Look at year 20. The stock's current yield is still ~3% — barely moved. But your yield-on-cost is 16.4%. Every dollar you invested 20 years ago is now spitting out 16.4¢ of income every year, and it'll keep climbing. That's the number retirees live off.
This is why DPP shows YoC as a first-class metric everywhere — on the backtest results, on Track My Holdings, and inside the AI Optimizer. Current yield is a snapshot; YoC is the trajectory.
High current yield often means low dividend growth (or a ). Low current yield with high growth means your YoC will crush the high-yielder's in 10–15 years. This is the core choice every dividend portfolio makes.
DRIP — how a $10k position becomes $47k
stands for Dividend Reinvestment Plan. Every dividend you receive is automatically used to buy more shares of the same stock — no commission, no button to press. Your quarterly $87 dividend becomes fractional shares that themselves start paying dividends next quarter. That's where the comes from.
$10,000 in SCHD, 20 years, dividends paid to cash and spent. You still earn ~$1,050/year in year 20 — but nothing compounded.
Same $10,000, same 20 years, same stock — but every dividend bought more shares. Year-20 income: $4,180/year.
Same investment. Same stock. Same market. The only difference is whether the quarterly dividend gets spent or reinvested. Over 20 years the compounding version is worth ~70% more — and the income it produces is four times larger.
This is why the DRIP toggle at the top of every DPP portfolio is not a small detail. Turn it on, run a 20-year , and watch the two lines diverge. Then imagine 30 years.

- DRIP OFF (spent)
- DRIP ON (compounds)
Model assumes constant yield growth + price appreciation. Real markets zig-zag — DPP's historic backtests use real daily data. Use this to feel the compounding, not to predict the future.
A stock paying a 3% yield growing 8%/year, with DRIP on: your effective annual from dividends alone is roughly 3% × (1 + 8%) = 3.24% compounding on top of price appreciation. Over 30 years, that's the difference between doubling your money once and doubling it three times.
How to read a backtest without fooling yourself
A replays a portfolio's rules on real historical data — what would $10k invested in SCHD + VYM + JEPI on Jan 1, 2010 be worth today? DPP's engine crunches thousands of daily price + dividend records to answer that in under a second.
But a backtest is not a promise. It's a stress-test. Here's what to actually look at:
SCHD 50% · VYM 30% · JEPI 20% · $10k · 20y · DRIP on
- Tan dot at year 15 · Peak. The high-water mark before the drawdown.
- Red dot at year 17 · Trough. Down -12.9% from peak — the number you must be able to stomach.
- Green dot at year 20 · Final value. Recovery + compounding leaves you at $30,130.
- Dashed line at $10k · your original principal. Distance from the curve = total gain.
DPP shows all four numbers side-by-side on every backtest, plus a comparison mode where you can pin two portfolios and see the winners row-by-row. The AI Optimizer's explanation card walks you through why one beat the other, in plain English.
Past performance doesn't guarantee future returns — no backtest can capture regime changes, tax law shifts, or your own emotional response to a -40% year. Use DPP's backtests to compare ideas and rule out bad ones, not to predict the future.
