How to read this comparison

Each column shows the same five percentiles per seniority: the 10th and 90th mark the edges of the typical range, the 25th to 75th box is where most people in the role land, and the bold tick is the median. Junior and mid figures are base pay; senior and staff figures fold in bonus and equity where that reflects how the market actually pays, which is why the jump from mid to senior can look steep.

Pay is not the same as spending power. A higher headline number in a more expensive city can leave you with less once rent and tax are accounted for. We list each city's cost-of-living index (New York = 100) under each column so you can weigh the raw figure against local costs yourself. Figures are converted to a common currency (USD by default, switchable above) at approximate rates so the two sides compare directly; we do not net out tax. The percentile chart in each column stays in that market's local currency.
