Timesheet Calculator 2026 | Weekly Hours & Overtime Totals

Question 1

How do I add up hours on a weekly timesheet?

Accepted Answer

Convert each clock-in and clock-out to minutes, subtract unpaid meal breaks, then divide by 60 to get decimal hours. For example 9:00 AM to 5:30 PM with a 30-minute lunch is 510 minutes minus 30, which is 480 minutes, or 8.00 hours. Add each day's decimal hours to get the weekly total — never add hours and minutes in mixed format, that's where most manual errors come from.

Question 2

How do I convert minutes to decimal hours for payroll?

Accepted Answer

Divide the minutes by 60. 15 minutes = 0.25, 20 minutes = 0.33, 30 minutes = 0.50, 45 minutes = 0.75, and 50 minutes = 0.83. Payroll systems require decimal hours, so 7 hours 45 minutes is entered as 7.75, not 7.45.

Question 3

Are unpaid lunch breaks deducted from my hours?

Accepted Answer

Yes, if the break is a genuine, uninterrupted meal period of 30 minutes or more where you're relieved of all duties. Short rest breaks of 5 to 20 minutes are compensable under federal rules and must stay in your paid hours. If you answer the phone or cover the floor during lunch, that break is working time and must be paid.

Question 4

When do overtime hours start on a timesheet?

Accepted Answer

Under the FLSA, after 40 hours in a workweek at 1.5× your regular rate. Several states add daily overtime: California, Alaska, Nevada, and Colorado pay overtime after 8 hours a day (California and Colorado also add double time after 12). Turn on the daily overtime toggle above to model those rules.

Question 5

Do paid holidays and PTO count toward the 40-hour overtime threshold?

Accepted Answer

Under federal law, no. Only hours actually worked count toward the 40-hour trigger, so a week with 8 hours of holiday pay and 36 hours worked totals 44 paid hours but zero overtime hours. Some union contracts and company policies are more generous and do count them — check your handbook or CBA.

Question 6

How should overnight shifts be recorded?

Accepted Answer

Record the actual clock-in and clock-out; this calculator handles shifts that cross midnight automatically. For the workweek boundary, hours are credited to the workweek in which the shift starts unless your employer's written policy splits them at midnight consistently.

Question 7

How long must employers keep timesheets?

Accepted Answer

The FLSA requires employers to keep time records for at least two years and payroll records for three years. In a wage dispute where the employer has no records, courts generally accept the employee's reasonable reconstruction of hours — which is why keeping your own copy matters.

Question 8

Can my employer round my clock-in time?

Accepted Answer

Rounding to the nearest quarter hour is allowed only if it's neutral over time — it can't systematically favor the employer. Always rounding down, or rounding punches to the start of a scheduled shift while ignoring early work, is a wage violation.
