Labor cost is included in the amount of work, do not have to calculate separately, if you want to know how much labor cost, the amount of work entered into the software can be found; labor cost as the basis for charging, the cost of the project (excluding tax) = direct cost of work + measures + overhead + profit.
Construction projects are generally labor costs accounted for 15% to 20% of the total price; materials and equipment costs (including freight) accounted for about 45% to 65%; machinery use costs accounted for about 3% to 10%; overhead costs accounted for about 25% of the total cost of any project is composed of labor costs, materials and equipment costs, construction machinery costs, overhead and other types of costs, and there is a reasonable proportion between them.
Supplement:? From the cost measurement and accounting of some projects and the original budget or list of comparison results, based on the quota, from the proportion of labor and material costs to analyze the cost can play a certain measurement effect, especially in the case of tighter time or analysis of the precision requirements are not very high is more effective.
Labor costs include wages, bonuses and allowances, excluding social security fees. Fees include social security fees (i.e., social insurance premiums), housing fund, engineering sewage charges, etc. Social security fees and housing fund is what we commonly known as the five insurance and one gold. Social insurance premiums include medical care, unemployment, pension, maternity, and work-related injuries. Because the social security fee belongs to the regulation fee, and the work injury insurance premium belongs to the social security fee, so the work injury insurance premium also belongs to the regulation fee.
Wages paid under special circumstances: refers to the wages paid at the hourly wage rate or a certain percentage of the hourly wage rate for reasons such as illness, work injury, maternity leave, family planning leave, marriage and funeral leave, personal leave, family visit leave, periodic leave, work stoppage for study, and the execution of state or social obligations in accordance with national laws, regulations and policies.
[1] Labor cost:
Labor cost = ∑ (Workday consumption × daily wage unit price)
[2] Basic wage:
Basic wage = average monthly wage of production workers ÷ annual average monthly legal working days
[3] Wage subsidy:
Wage subsidy = ∑ annual payment standard ÷ (annual calendar days -legal holidays) + ∑Monthly disbursement rate ÷ annual average monthly legal working days + disbursement rate per working day
[4]Production workers' auxiliary wages:
Production workers' auxiliary wages = annual invalid working days x (basic wage + wage subsidy) ÷ (annual calendar days - legal holidays)
[5]Employee Welfare Expenses:
Employee Welfare Expenses = (Basic Wage + Wage Subsidy + Production Workers' Auxiliary Wages) × Welfare Expenses Accrual Ratio (%)
[6]Production Workers' Labor Protection Expenses:
Production Workers' Labor Protection Expenses = Average Annual Expenses of Production Workers for Labor Protection Expenses ÷ (Calendar Days of the Year - Statutory Holiday)
Expanded:
The main factors affecting the labor cost savings or overruns are:
(1) Difference in the amount of man-days used. That is, the actual number of man-days consumed with the budget quota calculated on the basis of the difference in man-days used to illustrate the enterprise production workers' skills and efficiency.
(2) wage unit price difference. That is, the actual average daily wages of construction workers with the budget quota to take the average daily wage difference, to reflect the actual level of production workers with the budget quota level difference in the situation.
The actual average daily wage with the workers over the completion of labor quotas and get the excess bonus.
