Understanding these Petroleum Engineer salary numbers
We report percentiles, not a single average, because pay isn't evenly spread — a handful of very high earners would drag an average upward and mislead you. Here's exactly what each figure means.
Median (P50) — $140,595
Half of Petroleum Engineers in Chicago earn more than this and half earn less. It's the most honest "typical" salary — better than an average, which gets skewed by a few top earners.
25th percentile (P25) — $114,856
The lower end of the typical range: 75% of Petroleum Engineers earn more than this. It's common for early-career roles or lower-cost employers. Earning below it is grounds to negotiate.
75th percentile (P75) — $172,101
Your negotiation target: only 25% of Petroleum Engineers earn above it. Reaching P75 usually means seniority, in-demand specialisations, or simply negotiating from data. See how to negotiate.
90th percentile (P90) — $206,538
Top earners: only 10% of Petroleum Engineers make this or more — typically senior, highly specialised, or at the best-paying employers.
Gross vs after-tax pay
These figures are gross (before tax). What actually reaches your account depends on your country, state, and deductions. Estimate your net with the take-home calculator.
National vs Chicago pay
City figures apply the local market premium to BLS data, so Chicago differs from the US average by +10%. A higher number isn't always better once cost of living is counted.
Hourly rate — $68/hr
The hourly figure is the annual median divided by 2,080 (40 hours × 52 weeks). If you regularly work more than 40 hours, your real hourly rate is lower than this. Convert any salary with the salary calculator.
Why this differs from Glassdoor or Payscale
Those sites publish what people say they earn (self-reports), which skew high because higher earners report more often. Our figures come from mandatory employer payroll records (BLS OEWS), so they reflect the whole market — not just a vocal subset.

This page carries a confidence score of 97/100, based on the data source and coverage. US figures track the latest BLS release and refresh automatically; international figures use OECD/ILO data. See the changelog for live data freshness.
