Understanding these Medical Lab Scientist 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) — $70,036
Half of Medical Lab Scientists in London 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) — $58,383
The lower end of the typical range: 75% of Medical Lab Scientists 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) — $84,014
Your negotiation target: only 25% of Medical Lab Scientists earn above it. Reaching P75 usually means seniority, in-demand specialisations, or simply negotiating from data. See how to negotiate.
90th percentile (P90) — $99,003
Top earners: only 10% of Medical Lab Scientists 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 London pay
City figures apply the local market premium to BLS data, so London differs from the US average by +0%. A higher number isn't always better once cost of living is counted.
Hourly rate — $34/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.
How current and reliable is this number?
This page carries a confidence score of 84/100, 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.
