Seoul and Shanghai land in a broadly similar monthly budget bracket. Expect a language curve either way — Korean in Seoul, Mandarin Chinese in Shanghai. Both have full set-up guides below, so the real choice comes down to climate, career field, and the lifestyle you're after.
Prices are curated local figures shown in their own currency. USD totals and “% cheaper” claims use approximate exchange rates to put both cities on one scale — rough guidance for budgeting, not exact quotes. Ranges are averaged; annual rents are shown per month.
Seoul and Shanghai cost about the same month to month once rent and everyday spending are combined.
Both run on local + English at work, so the edge comes down to your sector. Seoul: Technology & electronics, Entertainment & K-culture, Gaming. Shanghai: Finance & capital markets, Automotive & EV, Semiconductors & hardware.
Seoul feels like “Hyper-connected megacity — palaces and street food beside K-pop, all-night cafés and the world's fastest internet”, while Shanghaiis “China's commercial capital — the deepest expat infrastructure on the mainland, and its own talent residence permit”. Climate is a real differentiator: Seoul — continental monsoon — hot humid summers, cold dry winters, four seasons. Shanghai — humid subtropical: sticky 35°c summers, a plum-rain june, and damp 4°c winters in buildings with no central heating.
