Holiday Pay Multiplier Calculator
Compute holiday pay at 1.5x, 2x, or any custom multiplier over the base wage.
The Holiday Pay Multiplier Calculator on ShiftClock is built specifically for shift-work payroll. Compute holiday pay at 1.5x, 2x, or any custom multiplier over the base wage.
How to use it: enter your start time, end time, and any unpaid breaks for each shift in the work period. The calculator returns total worked hours, overtime hours under the rule you select, and an estimated gross pay figure. All inputs stay on the page — nothing is sent to a server — so you can experiment with different scenarios privately. Cross-reference any result against the FLSA wage and hour reference manual before relying on it for payroll.
What it covers:
- Shifts that cross midnight, with automatic next-day handling.
- Multiple unpaid meal periods and paid rest breaks.
- Federal 40-hour overtime, daily double-time, and 207(k) public safety thresholds.
- Optional shift differential added on top of the base wage.
- Pay-period totals across daily, weekly, and biweekly views.
What it does not do: the calculator is informational and is not a substitute for a payroll system or legal advice. State and local rules vary, collective bargaining agreements may set higher rates, and unusual situations such as travel time, on-call status, or sleeping time deserve a closer look. The matching guide pages on ShiftClock walk through those edge cases.
If you are unsure which calculator to use, start from your schedule pattern. Each schedule directory entry links to the calculator that matches its overtime model. From the calculator, you can jump back to the schedule or to the related occupation pages to compare typical wages across roles using the same pattern.
