A shift calculator works out when a work shift ends and how many of those hours are paid. It starts from three facts: the clock-in time, the total length of the shift, and the length of any unpaid break. The arithmetic is simple — end time = start time + shift length, and paid hours = shift length − unpaid break — but it gets error-prone when a shift crosses noon or midnight, or when the length is written as a decimal such as 7.5 or 8.25 hours. A quick calculation avoids clocking out 30 minutes early or staying 30 minutes too long.
Several things change the answer. An unpaid meal break stays inside the shift but comes out of paid time, so an 8-hour shift with a 30-minute lunch means 8 hours on site and 7.5 hours paid. Overnight shifts roll past midnight: a 10:00 PM start for an 8-hour shift ends at 6:00 AM the next morning. Decimal hours matter too — 0.25 hour is 15 minutes, 0.5 is 30 minutes and 0.75 is 45 minutes. Nurses, warehouse and retail staff, security officers, and supervisors building schedules use these numbers to plan commutes, childcare, shift handoffs, and weekly hour totals.
To use this shift calculator, enter the shift start time, the total shift length in hours (quarter-hour steps or any decimal), and the unpaid break in minutes, then press Calculate. The result shows the clock-out time in 12-hour AM/PM format plus the paid time in hours and minutes. For example, a 9:00 AM start with an 8-hour shift and a 30-minute break returns a 5:00 PM end and 7h 30m paid. Set the break to 0 if breaks are paid. If you know the paid hours you need and want the break added on top, enter paid hours plus the break as the shift length (8.5 hours for 8 paid hours with a 30-minute lunch). Results are estimates for planning; employer timekeeping records determine actual pay.
Yes — if the shift crosses midnight, the end time will be on the following day.
Yes — the result shows both the clock-out time and your net paid hours.
Yes — use decimal values like 7.5 for seven and a half hours.
Results are estimates for planning purposes only.
Enter your shift start time, your total shift duration in hours, and any unpaid break time in minutes. The calculator instantly shows when your shift ends and how many hours you'll be paid for.
The formula is: End time = Start time + Shift duration. Paid hours = Shift duration − Unpaid break time.

Typically 7:00 AM–3:00 PM or 8:00 AM–4:00 PM. Standard in offices, retail, manufacturing, and most business environments. Full daylight hours — most common shift type in the US.
Typically 3:00 PM–11:00 PM or 4:00 PM–12:00 AM. Common in hospitality, retail, manufacturing, and emergency services. Catches the evening rush in consumer-facing industries.
Typically 11:00 PM–7:00 AM or 12:00 AM–8:00 AM. Common in healthcare, manufacturing, transportation, and security. Night shift differential pay — typically 10–15% extra — is standard in many industries.
Common in healthcare, emergency services, and some manufacturing environments. Typical patterns are 7:00 AM–7:00 PM (day) and 7:00 PM–7:00 AM (night). Employees typically work 3–4 shifts per week rather than 5.
Two separate work periods in one day — for example 6:00–10:00 AM and 4:00–8:00 PM. Common in food service and transportation. Some states require split shift premium pay when the gap between periods exceeds one hour.
Once you know your paid hours, multiply by your hourly rate for gross shift pay. For weekly totals, add paid hours across all shifts worked that week.
| Shift type | Typical paid hrs | At $18/hr | At $22/hr | At $28/hr |
|---|---|---|---|---|
| 8-hr shift (30 min break) | 7.5 hrs | $135 | $165 | $210 |
| 8-hr shift (no break) | 8.0 hrs | $144 | $176 | $224 |
| 10-hr shift (30 min break) | 9.5 hrs | $171 | $209 | $266 |
| 12-hr shift (30 min break) | 11.5 hrs | $207 | $253 | $322 |
| 12-hr shift (1 hr break) | 11.0 hrs | $198 | $242 | $308 |
Enter your shift start time and total shift duration in hours. Add your unpaid break time in minutes. The calculator shows your exact shift end time and total paid hours.
Yes — if your shift crosses midnight, the end time correctly shows the following day. For example, a shift starting at 10:00 PM for 8 hours ends at 6:00 AM the next morning.
Shift length is the total time from clock-in to clock-out. Paid hours is shift length minus any unpaid break time. A 9-hour shift with a 30-minute unpaid lunch = 8.5 paid hours.
Most full-time shifts are 8 hours. Retail and hospitality commonly use 6, 8, and 10-hour shifts. Healthcare and manufacturing often use 12-hour shifts with longer breaks built in.
Federal law requires overtime pay (1.5x your regular rate) for hours over 40 in a workweek — not per shift. California also requires daily overtime for shifts over 8 hours. Use the Overtime Calculator to find your exact overtime pay.
A rotating shift schedule cycles employees through morning, afternoon, and overnight shifts on a regular pattern — weekly, bi-weekly, or monthly. This calculator helps you find end times for any shift in the rotation.
Add your paid hours from each shift across the week. If you work five 8-hour shifts with 30-minute unpaid lunches, your weekly total is 5 × 7.5 = 37.5 paid hours. Use the Working Hours Counter for multi-day calculations.
Yes — enter your start time, set duration to 12 hours, and add your break time. A 12-hour shift starting at 7:00 AM with a 30-minute break ends at 7:00 PM with 11.5 paid hours.
If you need 8 paid hours plus an unpaid 30-minute lunch, you are on site for 8.5 hours: a 7:00 AM start ends at 3:30 PM and a 9:00 AM start ends at 5:30 PM. If your 8-hour shift already includes the lunch, a 9:00 AM start ends at 5:00 PM with 7.5 paid hours.
Under federal rules, short rest breaks of about 5 to 20 minutes are generally counted as paid work time, while a bona fide meal period — usually 30 minutes or more with the employee fully relieved of duty — generally is not. Many states have their own meal and rest break rules, so check state law and your employer's policy.
