Dividend backtest — what if you had invested years ago?

Pick a ticker, a lump sum and a starting point, and see where reinvesting every dividend would have taken it. Read the note under the results first: this is a scenario run on constant assumed rates, not a replay of actual market history.

Honest note: a true backtest needs historical prices and every historical dividend — data this free tool doesn't carry. Instead it runs the ticker's page assumptions (starting yield, dividend growth, price growth) as constants, so treat the result as “what these assumptions produce”, never as what the ticker actually returned.

What this backtest does — and what it doesn’t

This backtest is a scenario tool, not a replay of market history. It takes a starting amount and applies your assumptions — a yield, a dividend growth rate, a price growth rate, reinvestment on or off — across a stretch of years, so the sensitivity of the result is yours to interrogate.

1

Assumptions in, scenario out

No invented historical prices, no hidden data. Change one assumption and the whole result moves in a way you can explain.

2

Run it twice

Once optimistic, once with growth cut in half. Trust the gap between the two runs more than either number on its own.

3

Beware winner-picking

Testing only today’s famous names flatters the result. Real investors had to choose them before they were famous.

# $10,000 at a 3% yield, dividend growing 7% a year
year 1 income = $300
year 10 income ≈ $550 — nearly double, no new money added
with DRIP on, the share count compounds on top of that

Remember what a smooth scenario line leaves out: taxes, fees, inflation, and the years the market fell. Used with those limits in mind, a backtest is excellent for comparing strategies under identical assumptions — reinvesting versus taking the cash, growth versus high yield, starting earlier versus starting bigger.

Frequently asked questions

Quick answers about this backtest.

Is this real historical dividend data?

No. It applies the assumptions you choose, evenly, across the period. For a specific fund’s real payout record, start from its page — for example the SCHD calculator — and check the issuer’s distribution history.

Why not use actual prices?

Because a scenario you can interrogate beats a history you can’t. The point is to see how the outcome responds to yield, growth and reinvestment — not to admire a chart of the past.

What is a backtest actually good for?

Comparing strategies fairly: same money, same period, different rules. The DRIP vs cash guide walks through one such comparison in words.
