How to read these rates
Employee references are annual US median wages for the cited BLS occupation, which may cover several career paths. Freelance examples add $15,000 for benefits and $20,000 for business costs, then divide by 1,200 billable hours a year. Annual figures are rounded to the nearest $1,000 and hourly figures to the nearest dollar. Figures are before personal taxes, with no percentage fees.
