#salary

Earnings and employment outcomes for 170+ US college majors, from FiveThirtyEight's analysis of the U.S. Census American Community Survey. For each major: its category (Engineering, Business, Arts…), number of graduates and share who are women, median / 25th- / 75th-percentile earnings of full-time workers, unemployment rate and college-job counts. Look a major up by name or code, list a category, rank majors by earnings or unemployment, or search. Ideal for edtech, career-guidance, student-advising and HR analytics apps.

Gross-pay maths as an API — the everyday salary and wage calculations, computed locally and deterministically and entirely currency-agnostic. The convert endpoint turns a pay figure given at any cadence — annual, monthly, bi-weekly, weekly, daily or hourly — into all the others, using configurable hours per week, weeks per year and days per week. The overtime endpoint computes regular, overtime (time-and-a-half by default) and double-time pay from the hours worked, with adjustable thresholds and multipliers, and reports the effective hourly rate. The raise endpoint applies a percentage or fixed raise, or works out the percentage from a new salary. The prorate endpoint pro-rates a salary by a worked fraction, or by days worked over days in the period — for joiners, leavers and part-periods. Everything is gross pay only: it deliberately excludes tax, deductions and benefits, which are jurisdiction-specific, so the maths stays exact and never goes stale. Computed locally, instant and private. Live, nothing stored. 4 endpoints. Ideal for HR and payroll tools, job boards and offer calculators, freelance and contractor rate tools, and budgeting apps. This is gross-pay maths; for loan, interest and investment maths use a finance-calculator API, and for net/take-home pay apply your local tax rules separately.
