HOW TO USE THIS COMPETENCY-BASED LEARNING MATERIAL
Welcome to the module “Preparing Job Estimate”. This learning guide contains training
materials and activities for you to complete.
The unit of competency "Prepare Job Estimate" contains the knowledge, skills and attitudes
required for an Automotive Servicing. It is one of the basic Modules at National Certificate
Level I (NC I).
You are required to go through a series of learning activities in order to complete each
learning outcomes of the module. In each learning outcome there are Information Sheets,
Resource Sheets and Reference Materials for further reading to help you better understand the
required activities. Follow these activities on your own and answer the self-check at the end of
each learning outcome. Get the answer key from your instructor and check your work
honestly. If you have questions, please don’t hesitate to ask your facilitator for assistance.
Recognition of Prior Learning (RPL)
You may already have some or most of the knowledge and skills covered in this learner's
guide because you have:
 been working for some time
 already completed training in this area.
If you can demonstrate to your trainer that you are competent in a particular skill, you don't
have to do the same training again.

What Is Job Costing?
Job costing, also called project-based accounting, is the process of tracking costs and
revenue for each individual project. Job costing looks at each project in detail, breaking down the
costs of labor, materials and overhead. It makes fewer assumptions than other costing methods.
Job costing is commonly used in the construction industry, where costs vary widely from
job to job. But it’s also used by manufacturers, creative agencies, law firms and more. Because
job costing tracks costs in detail for each job, it can be a helpful tool for small business owners to
evaluate individual jobs and see if any expenses can be reduced on similar projects in the future.

Calculate cost of labor and parts to fix or replace each affected item and estimate the
salvage value of the total vehicle loss.
Analyze repair cost estimates and communicate with the collision repair manager or
foreman. Arrange a second appraisal if necessary.
Review cost effectiveness of repair versus replacement of parts. Determine fees associated
with repainting, converting to special purposes or customizing undamaged vehicles.
Fill out insurance claim forms to indicate repair or replacement cost estimates and
recommendations.
Follow up on all account receivable from insurance companies as well as individual
customers.
How to Calculate Job Costing
Job costing is calculated by accumulating the cost of labor, materials and overhead on a
specific job. The accounting activities involved in calculating job costing are:
1. CALCULATE LABOR COSTS
Calculate how much it costs your business to employ all staff members who will work on the
project per day. Multiply the payroll day rate by the amount of time you estimate you’ll need to
complete the job. If you’ll rely on subcontractors for work your company doesn’t complete itself,
factor those costs into your total labor costs for the job. It can help to get an estimate from each of
these contractors.
2. CALCULATE MATERIAL COSTS
Calculate the cost of all materials used on the job. For a construction business, this would
include materials such as lumber, wiring, screws and more. You may choose to add a margin to
these materials to cover other related costs including wastage or delivery fees.
3. ESTIMATE APPLIED OVERHEAD
Overhead is the most difficult cost to calculate, because you’ll need to rely on an
approximation instead of a more exact figure. You’ll need to estimate the total overhead costs
factoring into the job, including rent on your office, administrative costs and depreciation on the
equipment used. Many businesses apply a blanket overhead fee to each project, such as 10 percent
per job. An accountant can help you analyze your business and develop a specific approach to
overhead. Or, you can calculate your predetermined overhead rate.
Written as an equation, job costing is calculated like this:
Total Job Cost = Direct Materials + Direct Labor + Applied Overhead

PREPARE AND PRESENT ESTIMATES
What Is a Predetermined Overhead Rate?
The predetermined overhead rate is a calculation used to determine the estimated overhead
costs for individual jobs, during a specific time period.
Most businesses create annual budgets that include estimated overhead and estimated activity for
the year. You can use these budget estimates to calculate an overhead rate to apply to each of your
jobs.
To calculate your predetermined overhead rate, you use the following equation:
Predetermined Overhead Rate = Estimated Overhead / Estimated Activity
There are usually different activity estimates included in your budget; opt to use the activity that
applies most directly to your company’s overhead costs, for example, your estimated direct labor
hours.
1. PREDETERMINED OVERHEAD RATE EXAMPLE
You want to use job costing in your construction business, and you’re looking to calculate
your predetermined overhead rate to use for job costing. You estimate that in 2020, you’ll have
$500,000.00 in overhead costs. You also estimate that your employees will work 10,000 hours in
2020.
Your calculation would look like this:
500,000 overhead / 10,000 direct labor hours = $5 per direct labor hour
Now that you’ve calculated your predetermined overhead rate, you can apply it to jobs for the
purpose of job costing, as the applied overhead cost. For each direct labor hour worked, you’ll add
$5 of overhead to the job. This is your applied overhead.
To calculate job costing, you’ll remember we use the following calculation:
Total Job Cost = Direct Materials + Direct Labor + Applied Overhead
Job Costing Example
Your automotive shop completed a client car. The total cost of your shop billable labor hours is
10,000 and you will bill 2,500 in material costs. Your shop has determined your applied overhead
cost for the job is 8,500.
You now have all the elements you need. Here’s how to calculate job costing:
Direct Materials (2,500) + Direct Labor (10,0000) + Applied overhead (8,500) = 21,000
Your total job cost for your client’s car is 21,000.
