How is clock-out time calculated?

Add your required paid time and all your unpaid breaks to your clock-in time.

Clock-out time = clock-in time + required paid time + unpaid breaks
Paid time done = time since clock-in − unpaid breaks already taken
Paid time left = required paid time − paid time done

Timeline from a 7:45 AM clock-in to a 4:15 PM clock-out, with a 30-minute unpaid lunch, 4 hours 55 minutes of paid work done by 1:10 PM and 3 hours 5 minutes left
How much of your shift is left

Worked example: checking the clock at 1:10 PM

Priya, a home health OT, clocked in at 7:45 AM. Her agency pays 8 hours, and she took a 30-minute unpaid lunch.

  • Time since clock-in: 5 h 25 min (325 minutes)
  • Minus the unpaid lunch: 4 h 55 min of paid work done
  • Required paid time: 8 hours (480 minutes)
  • Paid time left: 3 h 5 min
  • Clock-out: 7:45 AM + 8 h + 30 min = 4:15 PM

Not sure how many paid hours you need?

If your schedule is built on a productivity target, your required paid time comes from your billable minutes, not a fixed 8 hours.

Required paid time = billable minutes ÷ (target % ÷ 100)

For example, 375 billable minutes at an 85% target means 441 paid minutes (7 h 21 min). Work that out with the therapy productivity calculator, then come back here during the day to watch the clock.

Billable minutesTargetRequired paid time
33080%6 h 52 min
36085%7 h 3 min
37585%7 h 21 min
40885%8 h 0 min
42090%7 h 46 min

Paid time rounded down to the whole minute.

What changes your clock-out time during the day

  • A longer lunch than planned. Every extra unpaid minute moves your clock-out later by the same amount.
  • A cancellation. If billable minutes drop and your target stays the same, your required paid time drops too. Recalculate before you start filling the gap with “extra” work.
  • An add-on patient. More billable minutes means more paid time at the same target.
  • Overnight shifts. If your shift crosses midnight, the calculator labels the result “next day.”

Frequently asked questions

What time do I leave after 8 hours with a 30-minute lunch?

Add 8 hours 30 minutes to your clock-in time. If you clocked in at 7:45 AM, that’s 4:15 PM.

Do short breaks count toward my time left?

Paid breaks of 20 minutes or less are work time under federal law, so they don’t add to your day. Only unpaid breaks push your clock-out later.

What if my current time is earlier than my clock-in time?

Either fix the times, or turn on the overnight option if your shift crossed midnight.

Does this calculate pay or overtime?

No. It’s a time planner only. Overtime and pay rules come from your employer and your state.

Can I use this on my phone during a shift?

Yes. It works in any mobile browser, and the current time fills in when you open the page.
