TL;DR: Concrete Flatwork contractors at $1M-$12M in commercial new construction target 6-9% net profit margin. Net profit = gross margin minus overhead rate. The most common causes of below-target net profit: overhead rate understatement (owner comp below market, equipment depreciation missing), markup confusion (20% markup produces 16.7% gross margin not 20%), and direct costs not fully captured in job costing.

FAQ
Frequently Asked Questions
What is a good net profit margin for concrete flatwork contractors?
Concrete Flatwork contractors at $1M-$12M in commercial new construction typically target 6-9% net profit margin. Under $1M revenue the target is 5-8% as overhead is a higher percentage of revenue at lower volume. At $6M-$12M the target improves to 7-10% as overhead dilutes with scale.
What is the difference between gross margin and net profit for concrete flatwork contractors?
Gross margin is revenue minus direct job costs divided by revenue. Net profit is gross margin minus overhead (SG&A). A concrete flatwork contractor with 24% gross margin and 16% overhead has 8% net profit. Gross margin reflects job performance. Net profit reflects business performance. Both need to be tracked separately.
Why do concrete flatwork contractors have lower net profit than expected?
Pump cost not allocated to pours inflates COGS on elevated slabs and understates gross margin. Overhead rate understated because owner comp is below market. Both compress net profit below target. The fastest fix is overhead rate recalculation from actual P&L SG&A divided by revenue. The second fastest is correcting the markup using the markup vs margin calculator.
How does overhead rate affect concrete flatwork contractor net profit?
Net profit = gross margin minus overhead rate. If gross margin is 23% and overhead rate is 17% net profit is 6%. If the overhead rate is understated by 3 points (actual is 17% but bids use 14%) every job is producing 3 points less net profit than planned. At $4M revenue that is $120,000 per year in net profit given away on every bid.
