Work-hour totals for timesheets and payroll

What this calculation answers

A work-hours calculation turns clock-in and clock-out times into paid time. You start with the gross span between the start and end time, subtract unpaid meal periods, keep paid short breaks in the total, and add each paid shift to the workweek or pay period. The result answers a practical question: how many hours should appear on the timesheet before payroll, billing, or scheduling review.

For U.S. timesheets, the federal overtime anchor is the FLSA workweek. Covered, nonexempt employees must receive overtime pay for hours worked over 40 in a fixed workweek, and that workweek is 168 fixed hours. It can start on any day and hour, but hours cannot be averaged across multiple workweeks to avoid overtime.

Use the shift-span formula

The basic formula is: clock-out time minus clock-in time minus unpaid break time equals paid work hours. Convert minutes to decimal hours by dividing minutes by 60. A 30-minute unpaid meal is 0.50 hours, a 45-minute unpaid meal is 0.75 hours, and a 15-minute paid rest break stays in the paid total when the employer provides it.

For example, a worker clocks in for 40 gross hours during the week and takes 4 unpaid meal hours. Paid work time is 36 hours. At $27.25 per hour, straight-time pay equals $981.00 before taxes, deductions, overtime, or premiums. The calculation is clean because the unpaid breaks are deducted before the weekly total is multiplied by the hourly rate.

Keep the period boundary fixed

The most common rollup mistake is mixing a pay period with the FLSA workweek. A biweekly payroll period can contain two separate 168-hour workweeks. Covered, nonexempt employees get overtime after 40 hours in each fixed workweek, not after 80 hours across two weeks. A 46-hour first week and a 34-hour second week still includes 6 overtime hours in the first week.

Daily and weekend hours also need careful labeling. The FLSA does not require extra pay for Saturdays, Sundays, holidays, or regular rest days unless weekly overtime is worked. State law, a union agreement, an employment contract, or employer policy can add stricter overtime, break, or premium-pay rules, so keep federal arithmetic separate from those overlays.

Treat breaks and rounding carefully

Federal law does not require lunch or coffee breaks for adult employees. When an employer provides short breaks, usually about 5 to 20 minutes, federal law treats them as compensable hours worked that count toward weekly overtime. A bona fide meal period is generally unpaid only when the employee is completely relieved from duty; an employee who performs duties while eating is still working.

Time-clock rounding also has limits. Federal rounding to the nearest 5 minutes, tenth, or quarter-hour is accepted only when it averages out over time and does not underpay employees for actual hours worked. A neutral rule can round up or down on different punches; a rule that consistently removes worked minutes creates a pay problem.

Move from calculation to workflow

A one-off calculation is enough when you need to total one shift, check a single weekly timesheet, or estimate straight-time pay from known hours. Use the clock span, subtract only unpaid relieved-of-duty meal periods, convert minutes by dividing by 60, and roll the paid hours into the correct fixed workweek.

A managed workflow becomes necessary when multiple people clock in and out, edit entries, submit weekly time, need approval, or hand totals to payroll or billing. Everhour Reporting can group approved time by person, project, date range, client, billable status, and other columns, then export reports in CSV, Excel/XLSX, or PDF for review.

Frequently Asked Questions

How do you calculate paid hours from a clock-in and clock-out time?

Subtract the clock-in time from the clock-out time to get the gross span, then subtract unpaid break time. Convert minutes to decimal hours by dividing by 60 before multiplying by an hourly rate. A 7-hour 45-minute paid shift is 7.75 hours, not 7.45 hours.

Can a meal period be deducted from worked time?

A bona fide meal period is generally unpaid only when the employee is completely relieved from duty and the break is long enough to qualify, commonly 30 minutes or more. If the employee answers calls, watches a station, helps customers, or performs duties while eating, that time remains hours worked.

Do short rest breaks stay in the total?

Short breaks provided by an employer, usually about 5 to 20 minutes, are compensable hours worked under federal law. They stay in the paid total and count toward weekly overtime for covered, nonexempt employees. Longer state-specific rest or meal requirements need separate review.

Does overtime use each week or the whole pay period?

Covered, nonexempt employees in the United States must receive overtime pay for hours worked over 40 in a fixed 168-hour workweek. A payroll period can include more than one workweek, but overtime cannot be averaged across those workweeks. Each workweek stands on its own.

Can rounded time punches change the paid total?

Rounded punches can change the paid total only under a neutral rounding practice. Federal rules accept rounding to the nearest 5 minutes, tenth, or quarter-hour only if it averages out over time and does not underpay employees for actual hours worked. Rounding that consistently favors the employer is not neutral.

How does Everhour Reporting help review work-hour totals?

Everhour Reporting turns approved time into customizable reports with 45+ columns, grouping, filters, date ranges, and export formats including CSV, Excel/XLSX, and PDF. Managers can review totals by person, project, client, billable status, or date range before payroll or billing use.

How can Everhour approvals protect submitted timesheets?

Everhour Timesheets let users submit weekly project hours or working hours for review, then managers approve, reject, or partially approve entries. Submitted time is locked unless withdrawn or rejected, and approved time stays locked for regular members, which protects reviewed totals from later edits.
