A Machine Learning Engineer in St. Louis earns a median of $99,600/year (about $48/hour). Most earn between $78,280 (25th percentile) and $130,370 (75th percentile); top earners (90th percentile) make $158,310 or more — 17% below the US average.

Understanding these Machine Learning 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) — $99,600
Half of Machine Learning Engineers in St. Louis 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) — $78,280
The lower end of the typical range: 75% of Machine Learning 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) — $130,370
Your negotiation target: only 25% of Machine Learning Engineers earn above it. Reaching P75 usually means seniority, in-demand specialisations, or simply negotiating from data. See how to negotiate.
90th percentile (P90) — $158,310
Top earners: only 10% of Machine Learning 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 St. Louis pay
City figures apply the local market premium to BLS data, so St. Louis differs from the US average by -17%. A higher number isn't always better once cost of living is counted.
Hourly rate — $48/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.

What counts as a "good" Machine Learning Engineer salary in St. Louis?
Around the median ($99,600) is solid and $130,370+ is strong — but "good" really depends on local costs. Check what the number is actually worth with the good-salary breakdown for St. Louis.
