Evaluating salary-to-expense ratios, Madrid presents a USI rating of 65.08 (Unaffordable), demonstrating higher structural pressure than London's 58.55 (Severe burden). Accounting for combined housing and baseline food overhead, residents in London retain approximately 41.45% of local earnings in net discretionary income versus 34.92% in Madrid—giving London a 6.53% advantage in localized purchasing buffer.

Both urban centers exhibit highly aligned housing allocation ratios (London: 45.54% vs Madrid: 49.93%), indicating similar rental market friction. Baseline food overhead remains comparable, with both locations requiring roughly 13.01% to 15.15% of local income for monthly grocery baskets.

Across southern European metros in Portugal, Italy, and Spain, food expenditure consumes a heavy 20–25% slice of local median wages. Current baseline food metrics draw from localized dining samples on Numbeo, which can be inflated by tourist-heavy dining districts. Primary baseline food shares will be recalibrated as standardized regional grocery baskets are established.
