Civil Contractor
Overhead Rate.

Civil contractors carry significant equipment overhead — loan payments, depreciation, insurance, and maintenance — that most other trades don't have at the same scale. Here is what normal overhead looks like for civil contractors at every revenue level from $1M to $500M+.

Overhead Benchmarks — Civil Contractors — By Revenue Band

What Normal Looks Like
At Your Revenue Level.

These benchmarks are drawn from SPM's work with commercial civil contractors and industry data. Calculate your actual overhead rate — total G&A expenses divided by total revenue for the trailing 12 months — and compare to your revenue band below.

How to use this data: If you're above the top of the range, specific categories need review. If you're below the bottom, you may be underinvesting in systems and staff. Use the benchmark as a target range, not a single number.

$1M – $5M
Overhead Rate
14–20%
Gross Margin Target
18–24%
Net Margin Target
5–7%
Largest Overhead Driver
Equipment payments
Small civil firms carry proportionally high equipment and owner overhead. Equipment loan payments, insurance, and maintenance on a $500K fleet against $2M in revenue is 10%+ of revenue before any other overhead.
$5M – $10M
Overhead Rate
12–17%
Gross Margin Target
20–26%
Net Margin Target
6–8%
Largest Overhead Driver
Equipment fleet cost
Scale begins to leverage equipment cost across more revenue. Field supervision and estimating start to become significant overhead components.
$10M – $25M
Overhead Rate
10–15%
Gross Margin Target
22–28%
Net Margin Target
7–9%
Largest Overhead Driver
Field management
Mid-size civil operations need dedicated estimating and PM staff. These technical hires add overhead but are necessary for bidding and executing larger scopes.
$25M – $50M
Overhead Rate
9–13%
Gross Margin Target
23–29%
Net Margin Target
8–10%
Largest Overhead Driver
Estimating and admin
Dedicated estimating staff, safety programs, and equipment management infrastructure are standard at this scale.
$50M – $100M
Overhead Rate
8–12%
Gross Margin Target
24–30%
Net Margin Target
9–11%
Largest Overhead Driver
Safety and compliance
Formal safety programs, environmental compliance infrastructure, and insurance scale with project complexity.
$100M – $500M
Overhead Rate
7–10%
Gross Margin Target
25–32%
Net Margin Target
10–12%
Largest Overhead Driver
Corporate overhead
Multi-region operations, corporate staff, and bonding infrastructure add overhead layers that smaller firms don't carry.
$500M+
Overhead Rate
6–9%
Gross Margin Target
26–33%
Net Margin Target
11–13%
Largest Overhead Driver
Corporate and finance
Finance, legal, and corporate overhead is significant at this scale but diluted across a large revenue base.

Trade note for Civil Contractors: Civil work is the most equipment-intensive trade. Equipment cost is the largest variable in overhead rate at $1M–$25M. As revenue grows, equipment cost gets spread over more jobs and overhead rate compresses. Field supervision and estimating become dominant overhead drivers above $10M.

Why Overhead Rate Gets Off Track

Three Reasons Your
Overhead Is Drifting.

01

Equipment Overhead Growing Faster Than Revenue

Every piece of equipment added — excavator, dozer, compactor — adds loan payment, insurance, and maintenance to overhead. When utilization drops below 50% on any piece, equipment overhead drags your rate above benchmark.

02

Field Supervision Coded as Overhead

Working foremen who spend the majority of their time on job sites should be coded as direct labor, not overhead. Miscoding field-working personnel inflates overhead rate and understates job margins simultaneously.

03

Estimating Cost Grows Without Revenue to Match

Adding an estimator or PM coordinator adds $70K–$120K to overhead. If that staff addition doesn't generate proportionally more revenue, overhead rate climbs immediately and stays high until the revenue catches up.

How SPM Manages It

Overhead Rate as a
Managed Number.

Monthly Overhead Rate Calculation

SPM calculates your overhead rate monthly in ControlQore — total G&A divided by total revenue — and compares it to the civil contractor benchmark for your revenue band. When overhead drifts above benchmark, we identify which specific categories are driving it.

Equipment Cost Allocation Review

Equipment payments, insurance, and maintenance that aren't allocated to specific jobs inflate overhead. SPM reviews equipment cost allocation during onboarding and builds internal equipment rates so equipment cost flows to jobs rather than sitting in G&A.

Trade-Specific Benchmark Tracking

Your overhead rate is compared to the civil contractor benchmark for your revenue band — not a generic construction average. Civil overhead norms are different from electrical or interior finish norms. You're measured against actual peers.

Common Questions

Straight Answers.

How do I calculate my overhead rate?
Add up every expense that isn't a direct job cost for the trailing 12 months — office staff, rent, insurance, equipment payments not allocated to jobs, vehicles, software, marketing. Divide by total revenue for the same period. That percentage is your overhead rate. Compare it to the benchmark for your revenue band above.
Does SPM serve civil contractors at all revenue levels?
SPM's direct engagement covers $1M–$12M in revenue. The benchmark data on this page covers the full revenue spectrum for reference. For contractors above $12M, SPM can make the right introduction to firms that specialize at larger scale.
