A time card calculation answers three practical questions: how many paid hours belong to the day, how many paid hours belong to the workweek, and whether covered nonexempt employees crossed the federal overtime threshold. The calculation starts with clock-in and clock-out times, then subtracts only unpaid break time. Short breaks provided by an employer, usually about 5 to 20 minutes, count as compensable hours worked under federal law.
The federal baseline uses the FLSA workweek, a fixed and regularly recurring period of 168 hours made from seven consecutive 24-hour periods. Covered, nonexempt employees in the United States must receive overtime pay for hours worked over 40 in that workweek at not less than 1.5 times the regular rate. State law, employer policy, or a contract can add stricter rules.
Start with each day's paid time, then add the days inside the same fixed workweek. A shift from 8:00 AM to 5:00 PM with a 1-hour bona fide unpaid meal period produces 8 paid hours. 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.
For example, an employee logs 8, 9, 8, 11, and 11 paid hours across five days at $23.70 per hour. The weekly total is 47 hours. Regular pay covers 40 hours, or $948.00. Overtime covers 7 hours at $35.55 per hour, producing $248.85. Total gross pay is $1,196.85 before taxes, deductions, state-specific premiums, or policy exceptions.
Reliable time card math needs consistent inputs before it needs advanced formulas. U.S. timesheet entries commonly use month/day/year dates and 12-hour AM/PM times, so each punch needs the right date, AM or PM marker, and break classification. Crossing midnight also needs date-aware math, because 10:00 PM to 6:00 AM belongs to an 8-hour span, not a negative total.
Rounding creates another common error. Federal time-clock rounding can use the nearest 5 minutes, tenth, or quarter-hour only if the practice averages out over time and does not cause employees to be underpaid for actual hours worked. A reliable time card total keeps actual punches visible, applies rounding consistently, and reviews the weekly total after all paid work time is included.
A one-off calculator is enough for checking a single shift, confirming a weekly total, or explaining why a paycheck estimate changed. It works when the inputs are already clean: clock-in, clock-out, break length, pay rate, and worker category. It also works for a quick federal baseline check before a payroll specialist applies state-specific overlays or company policy.
A managed workflow becomes necessary when many people submit time, managers approve corrections, or payroll needs a repeatable record. Everhour can turn Google, Outlook, and iCloud calendar events into timesheet entries within a configurable 15-minute to 3-hour window. All-day, recurring, and pre-connection events do not sync, so teams still need a review step before payroll or billing use.

A reliable total keeps the source punches, break classifications, daily paid hours, and weekly paid hours visible. The calculation subtracts bona fide unpaid meal periods only when the employee is completely relieved from duty. It also counts short paid breaks and unscheduled work the employer suffered or permitted before reviewing covered nonexempt employees for overtime after 40 hours in the fixed FLSA workweek.
The FLSA overtime calculation uses a fixed workweek of 168 hours, made from seven consecutive 24-hour periods. Hours cannot be averaged across multiple workweeks for overtime. A biweekly payroll period can contain one 35-hour week and one 47-hour week, and the 47-hour week still requires overtime review for covered nonexempt employees.
Federal law does not require lunch or coffee breaks for adult employees. Break requirements, when they exist, come from state law or employer policy. Federal pay treatment still matters: short breaks provided by an employer, usually about 5 to 20 minutes, are paid, while a bona fide meal period is generally unpaid only when the employee is completely relieved of duty.
A calculator can use rounded punches only when the rounding rule is lawful and neutral in practice. Federal time-clock rounding is accepted for the nearest 5 minutes, tenth, or quarter-hour only if it averages out over time and does not underpay employees for actual hours worked. Keep actual punches available for review before payroll relies on rounded totals.
The FLSA does not require extra pay for Saturdays, Sundays, holidays, or regular rest days unless weekly overtime is worked. A holiday or weekend shift still counts toward hours worked. Extra premiums can come from state law, an employer policy, or a contract, so the calculator's federal baseline should stay separate from those overlays.
Everhour connects Google, Outlook, and iCloud calendars so events with defined start and end times can become timesheet entries. Users choose a sync window from 15 minutes to 3 hours before or after events, while all-day, recurring, and pre-connection events are excluded from sync.
Everhour timesheets let users submit weekly project hours or working hours for review. Managers can approve, reject, or partially approve submitted time, and approved time stays locked for regular members, giving payroll a clearer record of accepted hours and needed corrections.
Use Everhour calendar-based timesheet entries for repeatable time capture, then review exceptions before payroll or billing so time card totals become an approved record.
