What Is Labour Cost?

Labour cost is the total amount a business spends on its employees. It includes both direct wages and additional employment expenses required to keep workers on the payroll.

Labour cost typically includes:

• Regular wages or salaries
• Overtime pay
• Payroll taxes
• Employee benefits
• Paid vacation and sick leave
• Retirement contributions
• Insurance costs
• Bonuses and incentives
• Training expenses

Knowing the complete labour cost provides a more accurate picture of business expenses than looking at wages alone.

Why Is It Important to Calculate Labour Cost?

Calculating labour cost accurately helps businesses make informed decisions. It allows you to:

• Set profitable prices for products and services.
• Prepare accurate project estimates.
• Control business expenses.
• Improve budgeting and financial planning.
• Increase operational efficiency.
• Measure employee productivity.
• Identify opportunities to reduce unnecessary costs.

Without calculating labour cost correctly, businesses may underprice their services and reduce their overall profits.

How to Calculate the Labour Cost: The Basic Formula

The simplest formula is:

Labour Cost = Employee Wages + Payroll Taxes + Employee Benefits + Other Labour Expenses

If you want the labour cost per hour, use this formula:

Labour Cost Per Hour = Total Labour Cost ÷ Total Hours Worked

This calculation gives you the true hourly cost of employing a worker.

Step 1: Determine the Total Hours Worked

Start by calculating the total number of hours worked during the selected period.

Include:

• Regular working hours
• Overtime hours
• Paid working hours

Exclude unpaid leave unless your company policy requires otherwise.

For example:

• Regular hours: 160
• Overtime: 10

Total hours worked = 170 hours

Step 2: Calculate Employee Wages

Multiply the employee’s hourly wage by the total hours worked.

Example:

Hourly wage = $25

Hours worked = 170

Employee wages = 170 × $25 = $4,250

If employees receive a fixed monthly salary, simply use the monthly salary as the wage amount.

Step 3: Add Payroll Taxes and Employee Benefits

Employee wages are only one part of labour cost.

Additional expenses may include:

• Payroll taxes
• Health insurance
• Retirement contributions
• Paid leave
• Workers’ compensation insurance
• Performance bonuses

Example:

Employee wages: $4,250

Payroll taxes: $400

Health insurance: $300

Retirement contribution: $150

Total labour cost = $5,100

Step 4: Calculate Labour Cost Per Hour

Now divide the total labour cost by total hours worked.

Example:

Total labour cost = $5,100

Hours worked = 170

Labour cost per hour:

$5,100 ÷ 170 = $30 per hour

Although the employee earns $25 per hour, the actual labour cost to the business is $30 per hour.

Example of How to Calculate the Labour Cost

Let’s look at a complete example.

A construction worker earns:

• Hourly wage: $28
• Hours worked: 160
• Overtime: 20 hours
• Payroll taxes: $500
• Benefits: $450

Step 1

Regular wages:

160 × $28 = $4,480

Step 2

Overtime:

20 × $42 = $840

Step 3

Total wages:

$4,480 + $840 = $5,320

Step 4

Add taxes and benefits:

Payroll taxes = $500

Benefits = $450

Total labour cost:

$5,320 + $500 + $450 = $6,270

Total hours:

180 hours

Labour cost per hour:

$6,270 ÷ 180 = $34.83 per hour

This example shows why businesses should never calculate labour cost based only on wages.
