Employee Schedule Calculator 2026 | Coverage & OT Cost

Question 1

How do you calculate schedule coverage for a week?

Accepted Answer

Multiply the hours you are open by the days you operate, then by the number of people who must be on the floor at once. A store open 14 hours a day, 7 days a week, needing 3 people on shift, has to fill 294 staffed hours. Add a buffer for callouts and approved leave, because a schedule built on perfect attendance turns into last-minute overtime every week.

Question 2

How much overtime does an understaffed schedule create?

Accepted Answer

Take the coverage hours you must fill, divide by your headcount, and anything above 40 hours per person is overtime. That is exactly what this calculator does. Six people covering 294 hours average 49 hours each, which means roughly 54 overtime hours a week paid at 1.5 times the regular rate — usually more expensive than hiring one more part-time employee.

Question 3

Is it cheaper to schedule overtime or hire another employee?

Accepted Answer

Overtime is cheaper for short spikes because it carries no recruiting, onboarding, or benefits load. It becomes expensive when it is permanent: every hour above 40 costs 50 percent more, and chronic overtime drives turnover and errors. Compare the overtime cost shown above with the straight-time cost of covering the same hours to see where your break-even sits.

Question 4

Do scheduled hours count as hours worked for overtime?

Accepted Answer

No. Overtime under the FLSA is based on hours actually worked, not hours scheduled. Paid time off, holidays, and unworked scheduled shifts do not count toward the 40-hour threshold unless a state law or contract says otherwise. Conversely, unscheduled work — an early clock-in, a working lunch, after-hours messages — does count, even if a manager never approved it.

Question 5

What is a predictive scheduling or fair workweek law?

Accepted Answer

Several cities and states require advance notice of schedules — commonly 14 days — plus predictability pay when a shift changes late, and premium pay for clopening shifts. Oregon has a statewide law, and cities including Seattle, San Francisco, New York, Chicago, Philadelphia, and Los Angeles have their own. They do not change overtime math, but they add penalty pay that a coverage plan should budget for.

Question 6

How do I schedule around a 40-hour overtime threshold?

Accepted Answer

Fix the workweek in writing, publish the schedule before the week starts, cap individual assignments at 40 hours unless overtime is intended, and watch mid-week totals rather than checking on payday. Overtime is measured per workweek and never averaged across two weeks, so a 48-hour week followed by a 32-hour week still owes 8 hours of premium pay.
