Cos'è Potere d'acquisto?

Il potere d'acquisto è la quantità di beni e servizi che un'unità di valuta consente di acquistare e serve a confrontare la ricchezza nel tempo (inflazione) e fra Paesi (parità di potere d'acquisto).

Purchasing power declines with inflation: CHF 100 in 2000 buys roughly what CHF 75 buys today. Real income (nominal income deflated by inflation) is the right measure of standard of living growth.

Purchasing power parity (PPP) compares currencies by what they actually buy locally rather than by exchange rate. The Big Mac Index is a popular illustration: in 2026, a Big Mac costs CHF 7.30 in Switzerland but USD 5.50 in the US, implying the Swiss franc is overvalued versus the dollar.

Esempio

A retiree drawing CHF 60,000/year today will need around CHF 89,000/year in 20 years to maintain the same purchasing power, assuming 2% annual inflation.
