OSHA 300A Hours Worked and Average Employees Calculator

Besides the case totals, the OSHA Form 300A summary wants two figures about your workforce: the annual average number of employees covered by the OSHA 300 Log, and the total hours worked by all of them. 29 CFR 1904.32 lists both among the things you enter. OSHA's forms package includes a worksheet for each, and this calculator follows its steps. For the average, add up the number of employees you paid in each pay period during the year, divide by the number of pay periods, and round the answer up to the next whole number. Include everyone: full-time, part-time, temporary, seasonal, salaried and hourly. A pay period in which you paid nobody still counts: it adds 0 to the total and 1 to the divisor. The worksheet is blunt that you cannot divide the number of W-2s by the number of pay periods, because the count has to be built up one pay period at a time. Acme Construction's worksheet example has 830 employee-counts across 26 pay periods: 830 / 26 = 31.92, which rounds up to an average of 32.

For the hours, use payroll or time records whenever you have them. The count is hours actually worked, including salaried, hourly, part-time and seasonal workers and other workers you supervise day to day, and excluding vacation, sick leave, holidays and any other non-work time, even if paid. When records do not show hours worked, OSHA's optional worksheet lets you estimate: full-time employees times the hours a full-time employee works in a year, plus overtime hours, plus the hours of part-time, temporary and seasonal workers. The estimate is added to the hundredth of an hour and rounded up once at the end, so 1,000.1 plus 999.9 is exactly 2,000, not 2,001. The hours total is also the denominator of every injury rate, so once you have it you can carry it straight into a TRIR or DART calculation. The full-time-equivalent figure divides your hours by 2,000, the length of a full-time year on OSHA's 200,000-hour base. The average on your 300A is a different count from the headcounts OSHA's size and electronic-submission rules use, so check each rule against its own definition.
