Shift Hours Calculator

Frequently asked questions

How do I calculate total hours for a shift?

Subtract the start time from the end time. A shift from 9:00 to 17:00 is 8 hours. For overnight shifts, add 24 to the end time if it is earlier than the start. A shift from 22:00 to 06:00 the next day is 8 hours: 06 + 24 = 30, minus 22 = 8. This calculator handles all of that automatically, including overnight shifts.

How do I calculate hours for a full week?

Add up each employee's daily shift hours across all days they worked. If someone works 8 hours Monday through Friday, their weekly total is 40 hours. This calculator totals hours per employee and per day automatically, so you can see at a glance who is close to overtime thresholds and where you may be over or understaffed.

What is the easiest way to track shift hours for a team?

The quickest method is to paste your existing schedule directly into the text input. Use the format: Employee Name, Day, start-end time. For example: Maria, Monday, 9:00-17:00. The calculator parses the text and totals everything in seconds. If your schedule is already in a spreadsheet, export it as a CSV and upload it directly.

How do I know when an employee hits overtime?

In most countries, overtime kicks in after 40 hours per week (US) or 48 hours per week (EU). Once you calculate the weekly totals, compare each employee's total against your local threshold. Any hours above the threshold are typically paid at 1.5x the regular rate. Scheduling software can flag this automatically as you build the schedule.

Can I use this to calculate hours from a photo of a schedule?

Not directly, but you can copy the shift times from a photo into the text input. Type each employee's name followed by their shifts, one per line, and the calculator will add them up. For recurring schedules, saving the text input as a template lets you reuse it each week with minimal changes.
