What Does This Mean?
London offers a Full Stack Developer salary of $88K USD, while Seattle offers $161K USD — a difference of -46% in raw terms.
After adjusting for purchasing power parity (PPP), London's salary is worth $122K in US purchasing power terms, versus $161K for Seattle. This means Seattle offers better real purchasing power for this role.
PPP adjustment accounts for differences in local prices — for example, housing costs 3x more in San Francisco than in Warsaw, so a San Francisco salary needs to be much higher to provide an equivalent standard of living.
