Big Mac Index 2026: Currency Over/Undervaluation Calculator

A Big Mac costs $5.79 in the US (January 2026). It's dearest in Switzerland ($7.99, franc ~38% overvalued) and cheapest in Taiwan ($2.38, ~59% undervalued). Pick a country or type any two prices and a market rate below to get the implied exchange rate and over/undervaluation in your browser.

Overvalued means the local currency buys more than the market rate implies it should. Rates are editable defaults (approx. early 2026) — swap in a live rate for precision.

Most Big Mac tools just project the US price onto other countries. The one question people actually ask — "is my currency overvalued or undervalued?" — needs the market exchange rate too, and almost no calculator lets you enter it. This one does: pick a country to load the January 2026 figures, or type any two prices and a rate to get the implied PPP rate and the valuation gap. Below it sits the full country table, the GDP-adjusted caveat, and why a burger is a rougher yardstick than it looks.

The short answer

A Big Mac cost $5.79 in the US in January 2026 — the baseline for the whole index. Converted to dollars, it is most expensive in Switzerland ($7.99), implying the franc is about 38% overvalued against the dollar, followed by Argentina (+20%), Uruguay (+19%) and Norway (+15%). It is cheapest in Taiwan ($2.38, about 59% undervalued), Indonesia (−56%) and India (−55%). The rule: if a burger costs more in dollar terms than in the US, that currency looks strong versus the dollar; if less, weak. But because a burger's price also bakes in local wages, rent and taxes, poorer countries look "cheap" for reasons that have little to do with exchange rates — which is why The Economist also publishes a GDP-adjusted version.

Prices in US dollars at market exchange rates, January 2026. The valuation column is the raw index: local price in dollars divided by the US price, minus one. Positive = currency overvalued vs the dollar; negative = undervalued.

Why the GDP-adjusted version matters

The raw index has a built-in bias: burgers are simply cheaper to make and sell where labour and rent are cheaper, so low-income countries look chronically "undervalued" even when their exchange rates are broadly fair. To correct for this, The Economist plots Big Mac prices against GDP per person and measures each currency against that trend line instead of against the US directly.

The adjustment narrows the gaps sharply. On the raw index Japan's yen looks roughly 46% undervalued; on the GDP-adjusted version the gap shrinks because Japan is a rich country where you'd expect burgers to cost more. The practical takeaway: use the raw index to compare countries at similar income levels, and lean on the GDP-adjusted version when comparing rich and poor economies. Neither is a trading signal — both are conversation starters about where real exchange rates sit.

Burger inflation vs CPI

Because it is measured in one everyday product, the Big Mac also works as a homemade inflation gauge — and it has outrun official inflation in the US. The average US Big Mac climbed from about $2.07 in 2000 to $5.79 in 2026, a rise of roughly 180%, well ahead of the roughly 98% increase in the US Consumer Price Index over a comparable window. Fast food is a beef-, labour- and rent-heavy basket, so it captures wage and commodity pressure that the broad CPI dilutes.

What the Big Mac Index gets wrong

  • It's not just currency. A burger's price reflects local wages, rent, taxes, competition and import duties — not only exchange rates. That is why the GDP-adjusted version exists.
  • Coverage gaps. McDonald's isn't everywhere — most of Africa is missing, which is why a parallel "KFC Index" was created for that region.
  • The product varies. India's "Big Mac" is a chicken Maharaja Mac (no beef), and portion sizes and recipes differ by country.
  • Prices can be political. Argentina was long suspected of suppressing its Big Mac price to flatter official inflation figures.

Used with those caveats, the index is a genuinely useful sanity check on whether a currency looks stretched — a starting point for the deeper forex work our models do, not a substitute for it.

From burgers to the broader picture. The Big Mac Index is one lens on currency value. Pair it with our strongest currencies in the world ranking, the live currency strength meter, interest rates by country, and forex market hours for a fuller macro read.

Methodology & data sources

The calculator computes the raw Big Mac Index between any two currencies. It converts the local Big Mac price to dollars (local price ÷ market rate), derives the implied PPP exchange rate (local price ÷ US price), and reports the over/undervaluation as (implied rate ÷ market rate) − 1 — mathematically identical to (local dollar price ÷ US price) − 1. "Burgers per $50" divides $50 by the dollar price to show real purchasing power. Country presets load the January 2026 Economist dataset (US base $5.79); the market rates in each preset are editable approximations for early 2026, so enter a live rate for precise valuations. All computation runs in your browser. Country prices and the historical global-average series are from The Economist's Big Mac Index as compiled by World Population Review; the underlying data and GDP-adjusted methodology are published by The Economist.

Frequently asked questions

What is the Big Mac Index?
An informal measure of purchasing-power parity created by The Economist in 1986. It compares a McDonald's Big Mac price across countries against the US price to judge whether currencies are over- or undervalued against the dollar. If a burger costs more in dollar terms than in the US, that currency looks overvalued; if less, undervalued. A US Big Mac cost $5.79 in January 2026.
Which currency is the most overvalued in 2026?
By the raw index for January 2026, the Swiss franc: a Big Mac costs $7.99 in Switzerland vs $5.79 in the US, implying about 38% overvaluation against the dollar. Argentina (+20%), Uruguay (+19%) and Norway (+15%) follow. The most undervalued are Taiwan (−59%), Indonesia (−56%) and India (−55%).
How do you calculate the Big Mac Index?
Divide the local Big Mac price by the US price to get the implied exchange rate, then compare to the actual market rate. If the implied rate is higher than the actual rate, the currency is overvalued; if lower, undervalued. The percentage equals (implied rate ÷ actual rate) − 1, which equals (local dollar price ÷ US price) − 1.
Is the Big Mac Index accurate?
It is a rough, deliberately light-hearted gauge, not a precise model. A burger's price reflects local wages, rent, taxes and competition, so poorer countries look "undervalued" for reasons unrelated to currencies. The Economist's GDP-adjusted version corrects for that. Use it to spot large, persistent gaps — not to time trades.
