About
Everyone has the trade they almost made. This site turns "almost" into a number.
What If I Held computes what any past investment would be worth today — the stock you sold too early, the crypto you joked about at a barbecue, the index fund you meant to open. Every calculation uses real historical closing prices with dividends reinvested.
The site is a calculator, not an advisor. It does not recommend, predict, or manage anything. It exists because looking at the road not taken is one of the oldest hobbies in finance, and it deserves accurate math.
Questions about the data or the site: see contact. If you want to check our work, the methodology page describes every convention.
