Found an error?
Pay rules, overtime thresholds, and differentials vary by employer and state, and payroll policies change. If a calculator result or guide looks wrong for your situation, tell us the page, the inputs you used, and what you expected. Corrections are prioritized over all other requests.
Calculator requests
ExtraShiftCalc is built around real questions hourly workers ask before picking up a shift. If there is a pay scenario you cannot model with the current calculators — a specific differential structure, a state rule, or a scheduling pattern — describe it and we will consider building it.
About the site
ExtraShiftCalc.com is an independent site that helps nurses and other hourly workers estimate what extra shifts, overtime, and differentials actually add to a paycheck after taxes and real-life costs. The calculators provide planning estimates only and are not tax, legal, payroll, or financial advice.
