About ClockOutMath

ClockOutMath is a set of free calculators for hourly workers, supervisors and small-business owners in the United States: time cards, hours, overtime, decimal hours and take-home pay.

Every calculator runs entirely in your browser. We do not ask for an account and do not send what you type to a server.

Our formulas follow the federal Fair Labor Standards Act (FLSA), Department of Labor regulations (29 CFR Parts 778 and 785), IRS and SSA published figures, and state agency publications. Read the methodology to see exactly how each number is produced.
