About This Calculator

Who We Are

This calculator started as a simple tool to answer one question honestly: what does a California paycheck actually look like after federal tax, state tax, SDI, and FICA are taken out. We're not a tax prep company or a financial institution — just an independent site built for California workers who want a straight, quick answer without creating an account or handing over their income to anyone. All calculations run in your browser; we never see or store what you type in.
