Clock Out Time Calculator

Enter your start time and shift length to instantly see what time you clock out. Free clock-out calculator for shift workers, nurses, and hourly employees.

Knowing exactly what time you get off work shouldn't require mental math. Whether you're a nurse finishing a 12-hour hospital shift, a retail associate on an 8-hour floor shift, or a factory worker running a 10-hour production line — this calculator gives you your clock-out time the moment you enter your start time.

Just pick when your shift starts, how long it is, and whether you have a paid or unpaid break. The result appears instantly: your clock-out time in both 12-hour and 24-hour format, your total paid hours, and an overtime indicator if you're crossing the 8 or 12-hour threshold.

Night shift workers are fully supported. If your shift crosses midnight, a "+1 day" label appears so you're never confused about whether 1:00 AM is today or tomorrow.

The "hours between two times" calculator below is useful when you already know your end time and want to confirm how many hours you're actually being paid for. And the weekly timecard tool lets you track multiple days at once — helpful for employees who work irregular schedules or split shifts.

Who uses this tool?

Shift workers across industries rely on this calculator daily. Hospital nurses managing 12-hour shifts need to know exactly when they hand off to the next team. Warehouse associates tracking 10-hour shifts during peak season use it to plan their commute. Retail managers scheduling overlapping shifts use it to avoid coverage gaps. Restaurant employees use it to calculate whether their doubles qualify for overtime pay.

How to use the Clock Out Time Calculator

  1. Enter your start time: Type or pick the time you started (or will start) your shift. Both 12-hour (AM/PM) and 24-hour formats are accepted.
  2. Pick your shift length: Select your paid shift length — 4, 6, 8, 10, 12 hours, or any custom value. Half-hour options are available.
  3. Add your unpaid break: Choose any unpaid break that extends your time at work. Common options are 15, 30, 45, or 60 minutes.
  4. Read your clock-out time: The result panel shows when you'll clock out, in both 12-hour and 24-hour formats. Overnight shifts display a +1 day badge.

Frequently Asked Questions

How do I calculate what time I get off work?

Add your paid shift length plus any unpaid break to your start time. For example, if you start at 9:00 AM and work 8 paid hours with a 30-minute unpaid lunch, you clock out at 5:30 PM. With no break, the same 8-hour paid shift ends at 5:00 PM.

Does my break time change when I clock out?

Yes — an unpaid break extends the total time you spend at work. So an 8-hour paid shift with a 30-minute unpaid lunch means you clock out 8 hours and 30 minutes after you started. Your paid hours remain 8.

What is the 'What time do I get off?' question really asking?

Most people want to know their clock-out time — when they physically leave the building. That's start time plus paid hours plus any unpaid break. This calculator gives you both that exit time and your paid hours.

How does overnight / night shift work in this calculator?

If your shift crosses midnight, the calculator detects this and shows a '+1 day' label. So a shift starting at 10:00 PM for 8 hours would clock out at 6:00 AM +1 day.

When does overtime start?

For most US workers, overtime starts after 8 hours in a workday (some state laws) or after 40 hours in a workweek (federal FLSA). California also mandates double-time after 12 hours in a day. This calculator flags daily overtime at 8 hours and double-time at 12 hours.

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).
