Confidence B Median total USD 173,522 a year. The p25 and p75 columns apply the formula to each input's p25 (the value a quarter of the data falls below) and p75 (the value a quarter of the data sits above); they are scenarios, not percentiles of the total. Footnote numbers point to the sources below.

|---|---|---|---|
| Base salary[1][2] 2 sources, spread 22% | USD 123,949 | USD 143,584 | USD 167,523 |
