Computing…

"Real Wealth Growth Rate" measures the annualised compound growth rate (CAGR) of a stock when priced in gold — hard money that cannot be printed. A positive value means genuine wealth creation. A negative value means purchasing power is shrinking, even if the dollar price rises.

Step 1 — Express share price in grams of gold

$$\text{SPY}_{\text{gold}}(t) = \frac{P_{\text{SPY}}(t) \times 31.1035}{P_{\text{gold}}(t)}$$

$P_\text{SPY}$ = stock price in USD, $P_\text{gold}$ = gold spot in USD/troy oz, $31.1035$ = grams per troy ounce.

Step 2 — Real Wealth Growth Rate (CAGR in gold terms)

$$\text{Real Wealth Growth Rate} = \left(\frac{\text{SPY}_{\text{gold}}^{(T)}}{\text{SPY}_{\text{gold}}^{(0)}}\right)^{\!\frac{1}{T}} - 1$$

$\text{SPY}_\text{gold}^{(0)}$ = initial gold-price, $\text{SPY}_\text{gold}^{(T)}$ = current gold-price, $T$ = number of years. A positive result means the stock outpaces gold.
