How to Use This in Negotiation
The classic negotiation move is to anchor your ask on the 75th percentile of the BLS band — $132,205 for Software Quality Assurance Testers in St. Louis, MO — when you have meaningful experience, then bring evidence (years on the job, scope of past work, relevant certifications, comparable offers) to justify why you sit at that point in the distribution. Anchoring on the median when you have 5+ years of experience leaves money on the table; anchoring on the 90th percentile ($169,820) without strong evidence undercuts credibility.
For new entrants, the 25th-to-50th percentile band ($73,596–$94,590) is the realistic target. For mid-career workers, the median-to-75th band ($94,590–$132,205) is the right anchor. Senior specialists and managers should be benchmarking against the 75th-to-90th band ($132,205–$169,820).
