10-Hour Shift Calculator

Calculate clock-out times for 10-hour shifts. Popular for 4-day work weeks, construction, and manufacturing. Includes overtime and break calculation.

The 10-hour shift has surged in popularity as companies adopt compressed workweek schedules. Working four 10-hour days gives employees a three-day weekend every week — a powerful recruiting tool and a schedule many workers prefer over the traditional five-day, 8-hour week.

This calculator is pre-filled for 10-hour shifts. Select your start time and it shows your clock-out time instantly, along with overtime hours (since 10 hours exceeds the 8-hour daily threshold in some states) and your total paid time after any breaks.

Industries that commonly use 10-hour shifts: - Construction and skilled trades (rotating 4/10 schedules) - Manufacturing and logistics (4-day production runs) - Healthcare (some hospital units and urgent care) - Law enforcement and emergency services - Oil and gas (extended field rotations)

The 4/10 schedule explained

In a 4/10 schedule, workers put in 40 hours across four days instead of five. This meets the federal overtime threshold exactly — no weekly overtime pay unless you're asked to work a fifth day. From the employee's perspective, every week has a guaranteed three-day weekend. Many workers report better work-life balance, lower commuting costs (one fewer commute day per week), and more flexibility for appointments and personal time.

Frequently Asked Questions

What time do I get off if I start at 6 AM and work 10 hours?

With no break, you clock out at 4:00 PM. With a 30-minute unpaid meal break, you clock out at 4:30 PM — paid hours remain 10, total time at work is 10.5 hours.

Is a 4-day, 10-hour schedule considered overtime?

Not at the federal level — 4 x 10 = 40 hours, which is exactly the federal overtime threshold. However, in states with daily overtime laws (like California), hours 9 and 10 each day are paid at 1.5x.

Do I get two breaks during a 10-hour shift?

Federal law doesn't mandate meal breaks, but most states require at least one 30-minute break for shifts over 8 hours. Some states (including California) require a second meal break for shifts over 10 hours.

What industries use 10-hour shifts most often?

Construction, manufacturing, logistics, law enforcement, emergency services, and some healthcare facilities. The 4/10 schedule is popular because it gives employees a consistent three-day weekend.

How many paid hours is a 10-hour shift with a 30-minute lunch?

10 paid hours. The 30-minute unpaid meal break extends your total time at work to 10.5 hours but doesn't reduce your pay.

Overtime thresholds reference the U.S. Fair Labor Standards Act (FLSA, 40 hrs/week at 1.5x) plus state daily overtime rules (e.g., California Labor Code §510: 8h/day OT, 12h/day double-time).
