This calculator shows how Fed inflation erodes your real purchasing power in El Salvador, where Bitcoin is legal tender but the US dollar calls every shot.
El Salvador adopted the dollar in 2001, which means every Fed rate hike, every bout of US inflation, every monetary policy decision in Washington hits your wallet in El Zunzal or Santa Ana with zero cushion. When US inflation ran at 8.5% in mid-2022, Salvadoran prices followed — locals and expats alike had no local central bank to absorb the shock. You're living the low-cost-of-living dream, but the dollar you're spending is quietly worth less every year.
When the US prints money, not all of that inflation stays domestic. Countries holding dollar reserves absorb a portion of it — effectively subsidizing US monetary policy with their own purchasing power.
As a dollar earner spending in El Salvador, you benefit from the dollar's reserve status — but the local inflation trend still erodes what you buy. This calculator shows both sides.

El Salvador made headlines in 2021 when President Bukele made Bitcoin legal tender alongside the US dollar. Most expats who moved to surf towns like El Tunco or retired near Lake Coatepeque quickly discovered the Bitcoin experiment is interesting in theory — but in practice, you are living in a fully dollarized economy where the Fed is your de facto central bank, and you never got a vote.
Here's the part that doesn't make the expat Facebook groups often enough: dollarization, adopted back in 2001, means El Salvador imports US monetary policy wholesale. When the Fed let inflation run hot through 2021 and 2022 — peaking near 9% annually — your grocery bill in San Salvador climbed right along with it. There's no Banco Central de Reserva adjusting interest rates to protect local purchasing power. What happens in Washington happens in your Airbnb lease renewal.
The Bitcoin legal tender law added a genuinely novel layer. In theory, a merchant in El Zonte can accept sats; in practice, the Chivo wallet adoption stalled and most daily commerce still runs on physical dollars. What the law did accomplish is making El Salvador a magnet for a specific kind of financially curious expat — people comfortable thinking about monetary systems, inflation hedges, and the long-term value of fiat. If that's you, you already understand why tracking real purchasing power matters.
The cost of living in El Salvador remains meaningfully lower than the US — a good meal in the capital runs $5 to $8, a beach rental can stretch a retirement budget comfortably. But cheaper prices don't mean you're insulated from dollar debasement. A dollar that lost 20% of its purchasing power since 2019 buys less here too. Run your numbers in the calculator and see exactly what that erosion looks like in real terms.
