Frequently asked questions

Is it free?

Yes. No account, no usage limits, and no paid tier. The site is supported by advertising.

Where does the data come from?

Yahoo Finance daily price history, fetched when you press Calculate. Results use the most recent completed trading day, not live intraday prices.

Are dividends included?

Yes. By default, every dividend is reinvested on its ex-date (total return). Turning off the Reinvested dividends switch shows price return plus the dividends paid out as cash. If the stock paid no dividends over your period, or its dividend breakdown isn't available, the switch is greyed out and the result uses total return.

Are stock splits handled?

Yes. Prices are split-adjusted, so a 4-for-1 split shows as four times the shares at a quarter of the price.

Why does another calculator give a different number?

Usually dividends. Some calculators ignore them, which understates returns. Others add cash dividends on top of dividend-adjusted prices, which counts them twice. Our method is on the methodology page.

Why doesn't it match my brokerage account?

Your account reflects actual trade prices, fees, taxes, and your broker's dividend reinvestment timing. We model one purchase at the closing price on your chosen date.

Does it include taxes, fees, or inflation?

No. All figures are before taxes and fees, in nominal native currency (i.e. not adjusted for inflation).

How far back can I go?

To January 1, 1930. Most tickers only have data from their listing date.

What if markets were closed on my date?

The calculation uses the next trading day's close.

Can I look up ETFs and crypto?

Yes, if Yahoo Finance lists them. ETFs use their normal ticker, such as SPY or VOO. Crypto uses Yahoo's pair format, such as BTC-USD.

Why can't I find a ticker?

Delisted, merged, or renamed companies are usually unavailable. Stocks on non-US exchanges need Yahoo's exchange suffix, such as SHOP.TO for Toronto.

Does it work for stocks outside the US?

Partly. Listings on non-US exchanges are shown in that exchange's own currency, even though the page shows a dollar sign, and the dividend breakdown is not always available for them. Where a company also trades in the US, the US ticker gives more reliable results.

Is this financial advice?

No. The site is for education. Past performance does not predict future returns.
