Advice 1: How to calculate labor hours

Effective work of any enterprise is impossible without planning. The plan of production or service, you need to know of such magnitude as the laborhour. At its core standardhour is a temporary standard for the performance of a particular production activities and reflects its complexity and, ultimately, has a direct impact on the cost of products or services. You can calculate it yourself.
How to calculate labor hours
The total number of working hours is equal to the number of employees engaged in production, multiplied by the time that was spent on the production of a product of common efforts of these workers. It is really spent the hoursof am, which could serve as a standard. This is because in the production process every minute working time are not used with equal intensity.
Note that the hourt of time was used for rest breaks. Suppose you expect normo-hour, s for a production unit, which employs 10 people within 1 working week with a total duration of 40 hours. During the day they do two breaks of 10 minutes each. Thus, the total time that 10 workers had spent breaks during the five-day working week will be:
(10 min. * 2 * 5days) * 10 people = 1000 minutes or 16.7 hourss.
Therefore considering the time spent at the break, the total time for manufacture of the product were as follows:
10 * 40 hours – 16,7 = 383 hour.
So your calculations were more accurate, they should consider the days of temporary disability and absenteeism. This figure may vary depending on the time of year and public holidays falling at different times. As practice shows, the average for the year is 4%. Check the estimated values using this parameter, the number of wasted man-hours will be equal to:
383 – (383 * 0,04) = 367,7 man-hours.
This figure is too theoretical and needs to be clarified because productivity for one business day are also different. At the beginning of the work day need time to prepare for work, and in the end to go home. In addition, hourt of time can be lost due to lack of materials, tool breakage. Such losses usually do not represent more than 7% of the time. With this in mind, the potential number of man-hours will be equal to:
367,7 — (0,07 * 367,7) = 367,7 — 27,7 = 342 man-hourand practically available.
Now, calculate the laborhours. If the productivity of this working group is not higher than normal and equal to 100%, the number of normo-hours will be equal to 342, if the efficiency of labor in this group is higher and equal to 110%, then your order will be 342 * 1,10 = of 376.2 laborhour.
For these calculations you can see that if the group charging the purchase order, the estimated execution time of which 400 hourss, the workers will not have time to run it for a week. Keep this in mind and solve the problem by increasing the number of workers or transfer hourti of the order to another unit.

Advice 2: How to calculate the standard number

The calculation of the normative number of staff required for the formation of the optimal number of employees of state enterprises. This administrative task allows you to achieve your goals and at the same time to observe the regime of work and rest of the staff given that some of the staff not come to work due to temporary incapacity, or another labor vacations.
How to calculate the standard number
To determine the required staff number of staff (W), which is optimal, use the following formula:
W = N * KN,
where: N – normative number of workers
KN – the planning factor to the absence of employees at work due to illness or being in regular employment vacation.
The required number of staff staff (W) is defined without technical staff to porters, drivers, cleaners.
KN is calculated according to the formula:
KN = 1 + Days,
where: DN – the share which is outside of time in the General Fund of working time for a certain statistical period. The total Fund of working time is determined according to production calendar. Days is calculated as the ratio of the amount of hours of absenteeism employees to work to the total working hours for a specified period.
When calculating Days, note that according to the law, in accordance with the Labour Code of the Russian Federation, the planned number of working days is 49. Among them: 28 working days – regular paid leave 7 working days – this provision of leave without pay and 14 working days – the norm of absenteeism on the basis of temporary disability leaves. When the 8-hour working day total number of hours during the year will be 392 hours.
To calculate labour force; (H) use the formula:
N = V / (FRv * Nvar * KVN),
Where: V – the planned volume of work in those units that are accepted in the enterprise,
FRv – Fund of working time for the upcoming planning period on the production calendar, expressed in hours,
Nwir – rate revenue.
KVN coefficient routine enforcement of regulations.
KVN coefficient is defined as the quotient of the magnitude of the planned revenues for the relevant period of the plan year to the amount of actual revenue of the previous year.
