ShiftPay: OT Pay Calculator
iPhone / Finance
Know your OT down to the dollar — before the check arrives.
ShiftPay is built specifically for California public safety and healthcare workers — firefighters, police officers, nurses, and state employees — who need accurate overtime calculations based on their actual labor rules, not generic formulas. All calculations are sourced directly from FLSA Section 7(k), CA Labor Code 510, IWC Wage Order 5, and current public safety MOUs — not estimates.
Private by default. All data stays on your device. No accounts, no subscriptions, no ads.
Accurate by design Every calculation follows the real legal framework for your role. Firefighters and police use FLSA 7(k) with 28-day work cycles. Nurses calculate daily and weekly OT under CA Labor Code 510. State employees follow standard 40h weekly thresholds. No guesswork, no spreadsheets.
Built for your schedule Enter your hours and instantly see your gross pay, net take-home, overtime breakdown, and shift differential — all in one screen. Quick-select buttons for your most common hour totals make it even faster.
Smart shift differential Select your shift type — day, swing, or night — and ShiftPay automatically applies the correct differential rate to your base pay before calculating overtime, just like your department does.
Cash or CTO Prefer compensatory time off over cash? Toggle CTO mode and see exactly how many hours you'll bank, including your running total against the 480-hour federal maximum.
Kelly Days for firefighters Working a 24/48 or 48/96 schedule? Activate Kelly Day mode and ShiftPay adjusts your hours automatically for the period — so your OT threshold reflects your actual worked hours, not your scheduled hours.
Compare scenarios Wonder how much more you'd earn working 240 hours instead of 216? The Compare tab shows two scenarios side by side — gross, net, overtime — so you can make informed decisions about extra shifts.
Profile comparison Curious how a firefighter's pay compares to a police officer's with the same hours and rate? The Profiles tab runs both calculations simultaneously, showing exactly how different OT thresholds affect your take-home.
Bills & goals allocation Add your recurring bills and savings goals and ShiftPay allocates your net OT earnings to each one automatically, in priority order — so you know if that extra shift covers your car payment before you take it.
ShiftPay is designed for informational purposes only. Calculations are based on publicly available federal and California labor law and are intended to help you understand your pay — not to constitute legal, financial, or tax advice. Always verify your earnings with your employer's official payroll records. Labor rules may vary by jurisdiction, bargaining unit, or individual employment contract.
