Mission & Technical Background

Computer engineer (M.Sc. student at Kocaeli University, B.Sc. Düzce University) with a dual degree in industrial engineering. Specializes in time-and-motion wage algorithms, FLSA statutory compensation structures, and open-formula payroll mathematics.

Many online paycheck and wage calculators are opaque "black boxes" that fail to account for modern labor law complexities—such as non-discretionary bonus regular rate adjustments under FLSA § 7(e), statutory overtime calculations, or local state bracket nuances.

Our mission is to provide 100% mathematically transparent, peer-auditable, and client-side payroll calculations. We publish every formula, cite every applicable title of the US Code and IRS Publication 15-T, and never store or transmit sensitive worker wage data.

Engineering Principles

• Zero Server Data Collection: All wage and tax computations execute in your local browser using Vanilla JavaScript. Your financial details never touch a server.
• Statutory Verification: Tax brackets, standard deduction thresholds, and FICA wage caps are cross-verified against official IRS bulletins annually.
• Clear Attribution: When local municipal or collective bargaining agreements supersede federal baselines, we provide explicit citations and contextual guidance.
