Porto: Portugal's second city, pricing below Lisbon
Porto's Big Mac sits modestly below Lisbon's price, reflecting the city's smaller economy, lower wage base, and less concentrated remote-worker presence. Porto's tourism sector has grown sharply since 2018 — port wine, the Douro Valley, and the city's UNESCO old town drive year-round visitor flow — but the per-capita income gap with Lisbon remains real.
For Big Mac Index analysts, Porto is the comparator that surfaces Lisbon's tourism-and-influx premium. The Lisbon-Porto spread has widened roughly 15-20% over the past five years; if Lisbon were just expensive because of broad Portuguese inflation, the gap would be flat. Porto's slower price drift is the control variable that makes the Lisbon premium visible. Watch this spread as one of the cleanest reads on intra-eurozone divergence inside a single small country.
