How to Fill Out a Timesheet Correctly

By Atharv · Updated July 19, 2026

A timesheet is the document your paycheck is built from, and small errors on it turn into real money, usually yours. Filling one out well takes about two minutes a day once you know what each field wants. Here’s the whole process, including a completed example you can copy.

What each field means

• Name / Employee ID: exactly as payroll has it. A nickname that doesn’t match the payroll system is a surprisingly common reason timesheets bounce.
• Week starting / pay period: the date of the first day covered, not the date you submit.
• Time in / time out: when you actually started and stopped working, including AM/PM. Record every out-and-back (like leaving for an unpaid lunch) if your sheet has multiple in/out columns.
• Break: unpaid time only, usually lunch. Short paid rest breaks typically don’t get recorded here.
• Daily total: hours worked that day, in decimal form (7 hours 30 minutes = 7.50, not 7.30).
• Weekly total and signatures: the sum of daily totals, signed by you and usually a manager. Your signature says “this is accurate,” so check it before you sign.

A completed example

Notice the details that make this sheet payroll-ready: real dates on each row, AM/PM on every time, breaks in hours:minutes, totals in decimals, and a day with no break marked with a dash rather than left ambiguous.

Habits that prevent errors

• Record times daily, not on Friday. Memory-based timesheets drift, almost always in the employer’s favor.
• Write actual times, not scheduled times. If you stayed 20 minutes late, that’s work time.
• Do the math last, and check it. Total each day, then the week. (Or paste your times into the time card calculator and let it total, apply overtime, and export the PDF.)
• Keep a copy. If a paycheck ever looks wrong, your own record is your evidence.

Mistakes payroll sees constantly

• Minutes written as decimals (7:45 entered as 7.45 instead of 7.75)
• Missing AM/PM, making a 3:00 finish ambiguous
• Lunch subtracted twice: once in the times, once in the break column
• Unsigned sheets, or totals that don’t match the daily rows
• Submitting for the wrong week or pay period
