Calculate daily, weekly, monthly, and yearly work hours and earnings. Track overtime and estimate take-home pay.
Work hours are the total time between clock-in and clock-out, minus breaks and any unpaid time. They can be tracked daily, weekly, or per pay period and are usually converted to decimal hours for payroll. A work-hours calculator handles multiple days, varied break lengths, overtime thresholds, and different pay frequencies, and returns the totals in hours, decimal hours, and gross pay if an hourly rate is entered.
Common full-day shifts with the lunch break deducted. Use the calculator above for irregular or multi-shift days.
