ShiftDifferentialCalculator.com was built to help hourly workers, nurses, security professionals, and shift employees fully understand their compensation.
Too many workers leave money on the table simply because shift differential calculations are confusing. Our mission is to make it effortless — no spreadsheets, no manual math, no guesswork.
Our calculator is completely free, private (no data is stored or transmitted), and works on any device. We follow standard industry differential rates and FLSA guidelines to give you accurate pay estimates.
Whether you work night shifts at a hospital, weekends at a warehouse, or holidays in security, our tool gives you clarity on what you should be earning.
