# Is there an API for GSA schedule labor rates (CALC)? Yes. GSA's CALC+ has a free public API of awarded GSA schedule ceiling labor rates by category, education and experience. This API loads the full CALC+ set nightly (355,886 rates on 14 Nov 2026) and adds /labor-rates/stats, which returns count, minimum, quartiles and maximum for a category in one call. They are the standard benchmark for pricing a proposal or checking that a quote is fair and reasonable.Checked on 2026-11-15.Official source: [GSA CALC+ API](https://open.gsa.gov/api/dx-calc-api/) | Rates loaded | 355,886 | | --- | --- | | Source | GSA CALC+ v3, full reload | | Refreshed | 14 Nov 2026 | | Stats | Count, min, quartiles, max | ## The answer in detail CALC rates are ceiling prices awarded on GSA schedules (mostly the MAS professional services categories), not what was actually billed on orders. They are the standard benchmark for pricing a proposal or checking that a quote is fair and reasonable.Category names are free text set by each contractor, so 'Senior Software Engineer' and 'Software Engineer III' are different rows.
