How much would I have made if I invested $X in Y on date Z?
A free, sourced calculator for official historical prices and price indexes — not forecasts, and not invented returns. Pick an asset, an amount, and a start date. Optional monthly contributions and an inflation adjustment (BLS CPI-U) are included. Stocks and equity ETFs are not in this version; neither are Bitcoin or Ether, because we have not found a free price history whose license clearly allows use on a commercial, ad-supported site.
Not financial advice. This is a historical thought experiment, not a recommendation to buy or sell anything, and not advice about your personal situation. Past performance is not indicative of future results. You can lose money.
Figures use official monthly series cited on each page (World Bank commodity prices, the FHFA House Price Index, and, when present, a Treasury-bill wealth index we compute from official yields). A real investment would have returned something different.

What you can do here
Start with the calculator above, compare every series on one table, or use the inflation calculator to see what a dollar in an earlier year buys at the latest CPI-U reading. The guides add longer, computed stories: best and worst years to buy gold, gold vs house prices vs T-bills, what $100 a month would have grown to, real vs nominal returns, and accounts of 1970s inflation and the 2008 crisis. Selected start-year pages cover gold in 2000 and 2011, silver in 2011, oil in 2008, and U.S. house prices in 2000 and 2006. A glossary defines the terms.
Commodity prices come from World Bank Commodity Price Data (the Pink Sheet), published under CC BY 4.0 and the World Bank Dataset Terms. House prices use the official FHFA House Price Index®. Inflation uses the BLS CPI-U. See data & methodology for licenses, formulas, and sources we considered and did not use.
