Real Purchasing Power (PPP-Adjusted)
The most honest comparison: take each net salary and adjust it for what it can actually buy in the local market. A dollar in United Kingdom buys more or less stuff than a dollar in Japan — this table shows the equivalent local purchasing power.
True winner (after cost-of-living): Japan
On average, 36.4% more real purchasing power across the salary levels compared. Note: this differs from the tax-only winner (United Kingdom) — once you account for local prices, the picture changes.
