Gross (straight time) $0.00
Overtime is the federal weekly rule (over 40 hours at time and a half), split per week. Gross is straight time only (rate times hours). For overtime pay and take-home after tax, send these hours to Plain Paycheck.
Runs entirely in your browser. Times, breaks, and rate are never sent anywhere.
How the total is figured
Each day's worked time is the clock out minus the clock in, minus the unpaid break. If the clock out reads earlier than the clock in, the day is treated as crossing midnight. The week is the sum of the days, and anything over 40 hours is marked as overtime at time and a half, the federal rule under the Fair Labor Standards Act. The exact math is on the methodology page.
Every figure shows in hours and minutes (8:15) and in decimal hours (8.25). Payroll systems usually want the decimal form, which the decimal hours calculator converts both ways.
Lunch, overtime, and rounding
Unpaid lunch is entered per day in minutes and subtracted from that day's total. Switch to biweekly for a two week card, which keeps two separate 40 hour overtime buckets rather than one 80 hour total.
Turn on punch rounding to round each clock time to the nearest 5, 6, or 15 minutes. Rounding is allowed within limits, and the rounding rules page explains how, including where it is no longer permitted. To see the pay effect of a rounding policy, use the rounding calculator.

Common questions
How does the time card calculator handle lunch breaks?
Enter the unpaid break for each day in minutes and it is subtracted from that day's worked time. A 30 minute lunch on an 8.5 hour shift leaves 8 hours. If the break is longer than the shift, the day floors at zero rather than going negative.
Does it work for overnight shifts that cross midnight?
Yes. If the clock out reads earlier than the clock in, the calculator treats the shift as crossing midnight and adds the hours after midnight. For example 10:00 PM to 6:00 AM is 8 hours. There is also a dedicated overnight shift hours calculator.
How is overtime calculated?
The weekly total over 40 hours is flagged as overtime at time and a half, the federal rule, and is split per week so a biweekly card keeps two separate 40 hour buckets. This tool gives the hours; for what overtime and regular hours pay after tax, use Plain Paycheck.
Is anything I type saved or sent anywhere?
No. Every calculation runs in your browser. Your clock times, break minutes, and pay rate are never sent to a server or stored, so the calculator works offline and keeps nothing after you close the tab.
Can I get the total in decimal hours for payroll?
Yes. The stamped total shows both hours and minutes (8:15) and decimal hours (8.25), which is the form most payroll systems want. The decimal hours calculator converts any single figure both ways.
