If you had converted a sum of money to gold on a past date, what would it be worth today — or on any date you choose? This calculator shows gold's performance compared to the most liquid alternative: short-term Treasuries with quarterly reinvestment. Both are stores of value you can access quickly. The comparison is direct.
Methodology
Gold and silver values computed from LBMA spot prices. Treasury value assumes 3-month T-bills reinvested quarterly at prevailing rates (FRED series DTB3). The chart shows both trajectories from your start date to end date. S&P 500 uses SPY adjusted close prices (total return; dividends reinvested). All calculations use the nearest available data point to your selected dates.
