About What If Invest

What the site does

Pick a stock or ETF, an entry date and an amount. The site shows the value today, the total return, the average annual growth rate (CAGR), the deepest drawdown and a comparison with the S&P 500 over the same period.

Besides the calculator there are ready-made pages for every ticker and entry year, a portfolio backtester, a ranking of leaders and laggards, a return heatmap and a savings-goal calculator.

Data

The database covers 99 US-listed stocks and ETFs with daily prices since 1990. Prices come from Yahoo Finance and are refreshed every day; the footer of each page shows the date of the latest quote. Formulas and assumptions are described on the methodology page.

What the site is not

What If Invest is an educational tool. It is not a broker, an investment adviser or a recommendation service: it does not accept money, execute orders or tell you what to buy.

All figures describe the past and are hypothetical. Past performance does not guarantee future results.

Access and independence

The site is free, requires no registration and is available in English, Russian, Spanish and German.

What If Invest is an independent project. It is not affiliated with Yahoo, any stock exchange or the companies whose shares appear on the site.
