Job Details

Labor Hours

hrs

Total estimated hours for the job

Hourly Labor Rate

Fully loaded rate (wage + burden + overhead)

Material Cost

All materials, supplies, and equipment for the job

Markup Percentage

Markup on total cost for overhead + profit (typically 20-50%)

Pro Tip: Always pad your labor estimate by 10-15% for unexpected complications. It's better to come in under budget than to eat the cost of overruns.

Why Accurate Job Costing Matters

Protect Your Margins

Every job that goes over budget eats directly into your profit. Accurate job costing means you know your break-even point before you start, and you can price with confidence. Contractors who track job costs consistently report 15-20% higher profitability than those who estimate from gut feeling.

Job Costing Best Practices

Track Every Cost: Materials, labor hours, equipment rental, permits, even small supplies
Include Overhead in Your Rate: Your hourly rate should reflect true cost, not just wages
Review Estimates vs Actuals: After every job, compare what you quoted vs what it actually cost
Build in a Buffer: Add 10-15% to labor estimates for unexpected issues
Use Consistent Markup: Don't guess — use a calculated markup that covers overhead and profit

Frequently Asked Questions

What should be included in job costing?

All direct costs: labor hours x rate, materials, equipment rental, subcontractor costs, and permits. Your markup then covers overhead and profit. Missing even one cost category can turn a profitable job into a loss.

How do I calculate labor cost for a job?

Multiply estimated labor hours by your fully-loaded hourly rate. Your loaded rate includes base wage plus taxes, workers comp, benefits, and payroll burden. A $25/hr wage typically costs $35-45/hr fully loaded.

What markup should I use for job costing?

Most contractors use 20-50% markup on total job costs. If overhead runs 15% of revenue and you want 10% profit, you need at least a 25% markup on costs.

How accurate should my job cost estimates be?

Aim for estimates within 5-10% of actual costs. Track every job and compare estimated vs actual to improve accuracy. Most contractors who track consistently improve within 3-6 months.

Should I include overhead in my labor rate or markup?

Either works, but be consistent. Some contractors build overhead into a higher hourly rate, others use a lower rate with higher markup. The key is that overhead is covered somewhere in your pricing.
