For niche titles, we do not treat a broader SOC family as an exact job-title wage.

- Take-home pay calculated using 2026 federal tax brackets (10%-37%), CA 2026 state income tax brackets after the standard deduction (top rate 13.3%), and FICA (Social Security 6.2% + Medicare 1.45%).
- Tax brackets and standard deduction ($16,100 single filer for tax year 2026) sourced from IRS Revenue Procedure 2025-32 and updated annually.
Authoritative data sources:
- BLS Occupational Employment and Wage Statistics, national and metro-area salary data
- O*NET OnLine, occupation tasks, alternate job titles, skills, and SOC crosswalks
- BLS Occupational Outlook Handbook, occupation outlook where a matching profile is available
