A Google Sheets hours-worked calculation answers one practical question: how many payable or billable hours came from the time entries in the sheet. The spreadsheet usually starts with a date, start time, end time, and unpaid break column. It then converts clock time into decimal hours so payroll, invoices, or internal reports can use a clean number like 8.50 hours instead of 8 hours and 30 minutes.
For U.S. timesheets, the calculation also needs the right category for each hour. Hours worked include required duty time and additional work the employer suffered or permitted, including unscheduled work before or after a shift. Covered nonexempt employees must receive overtime pay for hours worked over 40 in a fixed FLSA workweek, and hours cannot be averaged across multiple workweeks.
Google Sheets stores time as a fraction of a 24-hour day. A time such as 8:15 AM is not decimal 8.15, and 8 hours 15 minutes equals 8.25 hours after conversion. The basic row structure is elapsed time minus unpaid break time, multiplied by 24. In outline form, the formula is `(end - start - unpaid_break) * 24` when all three values are stored as Sheets time values.
For example, a row with an 8:00 AM start, 5:30 PM end, and 30-minute unpaid meal period has 9.50 gross hours. Subtract 0.50 hours for the unpaid meal, and the paid total is 9.00 hours. At $31 per hour, that day produces $279.00 in straight-time pay before taxes, deductions, overtime premiums, or state-specific rules.
Overnight rows need different spreadsheet logic because the end time can be earlier than the start time. Google Sheets can handle that with a `MOD(end - start, 1) * 24` structure before unpaid breaks are deducted. A 10:00 PM to 6:00 AM shift then totals 8 hours instead of a negative value. This detail matters when payroll exports rely on one decimal-hours column.
Break handling needs the legal rule behind the spreadsheet column. Federal law does not require adult lunch or coffee breaks. When an employer provides short breaks, usually about 5 to 20 minutes, federal law treats them as compensable hours worked. A bona fide meal period is generally unpaid only when the employee is completely relieved from duty, so a working lunch stays in the hours total.
Google Sheets can import Excel files, pull CSV or TSV data by URL with `IMPORTDATA`, or bring in a range from another spreadsheet with `IMPORTRANGE`. Those paths are useful when a team collects entries in one file and calculates totals in another. Date parsing still depends on the spreadsheet locale, so U.S. timesheets commonly need month/day/year dates and 12-hour AM/PM time values checked before totals are trusted.
The export step has a clear boundary. Google Sheets can download the final timesheet as Excel, PDF, CSV, ODS, and other formats, but it does not create a payroll approval trail by itself. A one-off spreadsheet works for a quick total. Recurring payroll or billing needs tracked entries, manager approval, locked periods, and a handoff record. Everhour Time Tracking covers that workflow with timers, manual entries, approvals, and locked time.

Google Sheets stores each time value as part of one day. A result of 0.375 means 37.5% of a 24-hour day, which equals 9 hours. Multiplying by 24 converts the internal day fraction into decimal hours that payroll, billing, and CSV exports can use.
Use a `MOD(end - start, 1)` structure before multiplying by 24. This prevents a shift such as 10:00 PM to 6:00 AM from producing a negative number. After that, subtract only unpaid break time that qualifies for deduction under the applicable rule or policy.
A sheet can subtract a break column, but the entry still needs the correct classification. Under the FLSA, short rest breaks of about 20 minutes or less count as hours worked. Bona fide meal periods of about 30 minutes or more are unpaid only when the employee is completely relieved from duty.
Locale mismatch causes many wrong totals. Google Sheets date recognition and displayed date-time options depend on spreadsheet locale, so imported CSV dates and AM/PM times can parse incorrectly. Check imported date and time columns before relying on the decimal-hours result.
Yes, a sheet can total hours inside each fixed workweek and split hours over 40 for covered nonexempt employees. The FLSA workweek is 168 fixed hours, seven consecutive 24-hour periods, and hours cannot be averaged across multiple workweeks for overtime.
Everhour Time Tracking captures task and project hours through live timers or manual entries, then feeds those entries into timesheets, reports, budgets, invoices, and payroll review. Admins can approve timesheets, lock completed periods, send reminders, and configure timer behavior before spreadsheet exports or payroll checks.
Track approved hours from timers and manual entries, then use Everhour approvals and locked periods to keep payroll and billing review tied to verified time records.
