“Someone’s sitting in the shade today because someone planted a tree a long time ago.”

— Warren Buffett

The wisdom of Warren Buffett reflects a value-based philosophy about investing that says investors are buying shares in a business, and encourages strategic thinking about investment time horizon. Before placing a buy order for a stock, a great question we can ask is whether we would still be comfortable making the investment if we couldn’t sell it for many years?

A “buy-and-hold” approach may call for a time horizon that spans a long period of time — maybe even lasting for a two-decade holding period. Suppose such a “buy-and-hold” investor had looked into buying shares of Ecolab Inc (NYSE: ECL) back in 2005. Let’s take a look at how such an investment would have worked out for that buy-and-hold investor:

Start date: 06/13/2005
$10,000

06/13/2005
  $105,775

06/12/2025
End date: 06/12/2025
Start price/share: $32.26
End price/share: $270.95
Starting shares: 309.98
Ending shares: 390.58
Dividends reinvested/share: $25.48
Total return: 958.29%
Average annual return: 12.51%
Starting investment: $10,000.00
Ending investment: $105,775.11

As shown above, the two-decade investment result worked out quite well, with an annualized rate of return of 12.51%. This would have turned a $10K investment made 20 years ago into $105,775.11 today (as of 06/12/2025). On a total return basis, that’s a result of 958.29% (something to think about: how might ECL shares perform over the next 20 years?). [These numbers were computed with the Dividend Channel DRIP Returns Calculator.]

Notice that Ecolab Inc paid investors a total of $25.48/share in dividends over the 20 holding period, marking a second component of the total return beyond share price change alone. Much like watering a tree, reinvesting dividends can help an investment to grow over time — for the above calculations we assume dividend reinvestment (and for this exercise the closing price on ex-date is used for the reinvestment of a given dividend).

Based upon the most recent annualized dividend rate of 2.6/share, we calculate that ECL has a current yield of approximately 0.96%. Another interesting datapoint we can examine is ‘yield on cost’ — in other words, we can express the current annualized dividend of 2.6 against the original $32.26/share purchase price. This works out to a yield on cost of 2.98%.
