Frequently Asked Questions
How is overtime calculated?
Hours exceeding 8 per day or 40 per week are typically overtime. The tool flags these hours and applies the overtime multiplier you set (usually 1.5x).
Can I subtract lunch breaks?
Yes. Enter separate time blocks for morning and afternoon work, or use the break deduction field to subtract a fixed break duration.
Does it handle overnight shifts?
Yes. If the end time is earlier than the start time, the tool assumes the shift crosses midnight and calculates accordingly.
