Job Costing and Overhead Recovery
Separate direct cost from overhead, allocate overhead defensibly, and compare estimated to actual results.
Short answer
Direct costs are traceable to a job; overhead supports the business as a whole. Overhead must be recovered through pricing using a defensible allocation base, and comparing estimated to actual job cost is what improves future bids.
01
Classify costs correctly first
Materials, job labor, labor burden, equipment used on the job, subcontractors, permits, and disposal are typically direct. Rent, office staff, insurance not job-specific, software, and marketing are typically overhead.
Misclassification distorts both pricing and profitability analysis, so the exam tests classification before computation.
02
Choose an allocation base you can defend
Overhead is commonly recovered as a percentage of direct cost, per labor hour, or per unit of production.
- Percentage of direct cost
- Rate per direct labor hour
- Rate per square or per unit installed
- Blended approaches for mixed work
- Recalculation when volume changes materially
03
Estimated versus actual is the whole point
Job costing only creates value if actual results feed back into estimating. Track variance by cost category rather than as a single lump number.
A pattern of labor overruns points to productivity assumptions; a pattern of material overruns points to takeoff or waste assumptions.
04
Watch the volume trap
Overhead recovery rates assume a volume level. If volume drops, the same overhead spreads across fewer jobs and the rate becomes inadequate.
Exam questions may present a volume change and ask what happens to required markup.

Candidate questions
Frequently asked questions
Is labor burden direct or overhead?
Burden on job labor is generally treated as a direct cost of that labor. Office payroll burden is overhead.
What is the best overhead allocation method?
The one that reflects how your business consumes overhead and can be applied consistently.
How often should rates be recalculated?
Whenever volume, cost structure, or business mix changes materially.
