Question 1

What would $1,000 invested in Apple 10 years ago be worth today?

Accepted Answer

A $1,000 investment in Apple in mid-2015 would be worth roughly $10,000–$12,000 today on a split-adjusted, price-only basis — an approximate 10x return over the decade, or about 25% annualized. Apple went through a 7-for-1 split in 2014 and a 4-for-1 split in 2020, both of which are automatically factored into the split-adjusted share count. Add in reinvested dividends and the total return is a few percentage points higher. Enter Apple with a 2015 purchase date above to see the exact split-adjusted number.

Question 2

How do I calculate what a stock would be worth today if I invested years ago?

Accepted Answer

You need three things: the price on the day you would have bought, the total number of splits that have happened since then, and today's price. Divide your investment amount by the historical price to get your original share count, multiply by the cumulative split ratio (e.g. 4-for-1 = ×4), then multiply that split-adjusted share count by today's price. This calculator automates all three steps so you can compare 'what if' scenarios across any covered company in seconds.

Question 3

What is a good annualized return (CAGR) for a long-term stock investment?

Accepted Answer

The S&P 500 has delivered a long-term average of about 10% per year including dividends, or roughly 7% after inflation. Individual stocks vary widely: mature blue chips typically compound at 8–12% annualized, high-growth names like NVIDIA or Amazon have exceeded 25% CAGR over long stretches, and speculative bets can produce triple-digit CAGRs or wipe out entirely. Anything meaningfully above 15% annualized over 10+ years is exceptional and rarely sustained by the same name in the following decade.

Question 4

Do stock splits actually change how much my investment is worth?

Accepted Answer

No — a split does not create or destroy value on the effective date. A 2-for-1 split doubles your share count and halves the price; the value of your position is identical the moment before and the moment after. Over long periods, however, splits matter for accurate 'what if' math: without split adjustment, a stock that traded at $500 in 2010 and $200 today after two splits looks like a loser when it's actually up 4x. Every calculation on this page is split-adjusted automatically.

Question 5

Should I include dividends when calculating historical stock returns?

Accepted Answer

Yes, if you want the true total return — dividends have historically contributed 30–40% of long-term S&P 500 returns and matter even more for mature payers like Johnson & Johnson, Coca-Cola, or Realty Income. This calculator focuses on price appreciation to keep the math clean and transparent. As a rough add-on, multiply the company's average dividend yield by the number of years you held to approximate the dividend contribution to total return.
