Build or audit job cost and price from labor, materials, equipment, overhead, markup or margin, with gross profit and per-unit economics.

Blank additional costs and overhead mean $0. Blank billable units means one whole job.

USD cost and pricing scenario. Enter a burdened labor rate; avoid counting the same overhead twice. Taxes, financing and unentered costs are excluded.

Job Cost Formula

The following formula is used to calculate the Job Cost. 

JC = MC + L × T
  • Where JC is the Job Cost ($)
  • MC is the material cost ($) 
  • L is the labor cost per hour ($/hr) 
  • T is the total hours needed for the job (hr) 

The formula above covers labor and materials only. The calculator adds equipment, subcontractor/other direct costs and allocated overhead to obtain total job cost. Avoid counting overhead already included in the burdened labor rate twice. Price from markup equals total job cost × (1 + markup/100); price from margin equals total job cost / (1 − margin/100). Profit here means selling price less all entered job costs and allocated overhead; it is not necessarily accounting gross profit.

How to Calculate Job Cost?

The following example problems outline how to calculate Job Cost.

Example Problem #1

  1. First, determine the material cost ($). The material cost ($) is given as 130.
  2. Next, determine the labor cost per hour ($/hr). The labor cost per hour ($/hr) is calculated as  30.
  3. Next, determine the total hours needed for the job (hr). The total hours needed for the job (hr) is found to be 50.
  4. Finally, calculate the Job Cost using the formula above: 

JC = MC + L * T

Inserting the values from above yields: 

JC = 130 + 30 * 50 = 1630 ($)

FAQ

What factors can affect the accuracy of a job cost calculation?

Several factors can affect the accuracy of a job cost calculation, including unexpected increases in material costs, changes in labor rates, unforeseen delays that extend the job duration, and inaccuracies in the initial estimates of materials or hours needed.

How can one improve the accuracy of job cost estimates?

Improving the accuracy of job cost estimates can be achieved by conducting thorough research to get accurate material and labor rates, adding contingency allowances for unexpected costs, using historical data from similar projects, and regularly reviewing and adjusting estimates as the project progresses.

Are there any tools or software recommended for job cost calculation?

Yes, there are several tools and software available for job cost calculation, including project management software with built-in costing tools, specialized job costing software, and spreadsheets customized for cost calculations. These tools can help streamline the calculation process and improve accuracy by incorporating real-time data and analytics.
