Methodology & Data Sources
How we calculate Astronomer salaries in San Francisco, CA:
- Base salary model starts with Salario occupation data and public wage references, including BLS OEWS and O*NET when a direct or related occupational crosswalk is available (the national median is calibrated to the BLS OEWS May 2025 median for Astronomers). For niche titles, we do not treat a broader SOC family as an exact job-title wage.
- Cost-of-living adjustment applied using the San Francisco index of 180 relative to the national baseline of 100, with local rent, home price, unemployment, and tax inputs stored separately in Salario's city dataset.
- Percentile distribution (P10-P90) estimated from the entry, median, senior, and top compensation tiers in the Salario salary model rather than claimed as exact employer payroll data.
- 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
- BLS Consumer Price Index (CPI-U), regional inflation data (CPI measures price changes, not city-to-city price levels)
