About

How much would I have made is a free calculator for a simple question: if I had put $X into Y on date Z, what would that position be worth at the latest observation in our files? You can also model a monthly contribution and view the result after inflation.

Every figure on this site is computed from a published official series. We do not invent returns. This version uses World Bank monthly average commodity prices, the FHFA House Price Index® for U.S. house prices, and the BLS CPI-U for inflation. It is not a brokerage, does not hold assets, and does not offer financial, tax, or investment advice.
