Hey Product Hunt! I built Employer Cost API because every time I tried to calculate the real cost of hiring in the U.S., it turned into a mess. Payroll taxes, workers’ comp, benefits, PTO, insurance, retirement match — everything lives in different places, and most tools only focus on take-home pay. This project actually grew out of my previous Salary After Tax API, which calculates take-home pay across all U.S. states. While working on it, I realized there was still no simple, developer-friendly way to get a full employer cost breakdown — so this API became the next step. Right now it returns a clean JSON structure with all major components of employer cost. I’d love feedback on: — the API format (naming, structure, fields) — what data points or cost categories you’d expect — how to make the integration smoother for devs
