Time Card Calculation Guide
A weekly time card is most reliable when each day's worked minutes are calculated first and only then combined into the weekly total.
Calculate each day first
For every worked day, calculate clock-out minus clock-in, account for an overnight shift if appropriate, and subtract that day's unpaid break. Keep each result in integer minutes.
Add the weekly total
Sum the daily worked minutes only after validating every row. Divide by 60 for decimal hours, or divide into whole hours and remaining minutes for an hours-and-minutes total.
Weekly example
Five 8-hour days total 2,400 minutes, or 40 hours. If one day is 8 hours 30 minutes, the weekly total becomes 40 hours 30 minutes, which is 40.50 decimal hours.
Separate overtime carefully
An overtime threshold can split the total into regular and overtime hours, but the correct threshold and eligibility depend on the governing policy and law. Do not infer a rule solely from a time-card total.
Cross-check the record
Review missing punches, AM/PM errors, overnight rows, paid versus unpaid breaks, and any rounding policy before submitting a record.
