YOUR OVERHEAD RATE IS WRONG BY DESIGN.
Most subcontractors calculate overhead by dividing last year's overhead costs by last year's revenue. That's wrong for three reasons: the revenue base is stale, the cost categories are incomplete, and field costs that belong in job cost get included in overhead. The result is a number that's 5 to 15 points too low, baked into every estimate and compounding on every job you win.
The standard overhead target is 10 percent. Most subcontractors are running 25 to 42 percent and have no idea, because the number they carry into every bid was built once a year off a denominator that was already out of date. That distance, 15 to 32 points, is what the wrong calculation costs on every job you price and win. It doesn't read as a bad month on the P&L. It reads as a busy year that ends with no money in the account and no obvious reason why.
WHAT IT MEANS.
An overhead rate is the percentage of revenue consumed by the cost of running the business rather than the cost of building the work.
The rate is a pricing input. Every bid you send out carries it, and it sits underneath the markup whether anybody checked it or not. A rate that's 8 points light doesn't cost you 8 points once, it costs you 8 points on every job you win for as long as the number goes unchecked.
THE FOUR REASONS IT COMES OUT WRONG.
Stale revenue base
You divide last year's overhead by last year's revenue, and this year's revenue is different. If revenue grew 30 percent and overhead didn't change, the rate reads lower than it is. If revenue dropped, the rate reads higher. The denominator is always wrong because you're using history to estimate a forward cost structure. The overhead rate should be calculated on projected revenue rather than last year's actual.
Missing cost categories
The standard overhead list is rent, utilities, and insurance. What gets missed is owner salary priced at market value rather than what you pay yourself, benefits for office staff, software subscriptions, training, professional services, business taxes and licenses, vehicle costs for non field staff, and a scenario plan for the slow season. Most subcontractors are missing 20 to 35 percent of their true overhead in the calculation.
Field costs blended into overhead
Superintendent time that belongs to a specific job goes to overhead. Project management hours for a specific contract go to overhead. Equipment maintenance for a piece that only worked one job goes to overhead. When direct job costs get absorbed into overhead, the overhead rate is overstated and the job margins are understated. You're hiding job costs inside overhead and reading a distorted picture of both numbers.
Never updated mid year
You added a PM in February. Office admin went full time in April. The workers comp renewal came in 12 percent higher in June. Each of those moved your true overhead rate. Most subcontractors calculate overhead once a year at tax time, so by June the rate is already wrong and every bid from February forward used the wrong number.
WHAT IT LOOKS LIKE IN DOLLARS.
The standard overhead target is 10 percent. Most subcontractors are running 25 to 42 percent without knowing it. That distance, 15 to 32 points, is what the wrong calculation costs you on every job you price and win.
THREE STEPS, IN ORDER.
Fixed costs are rent, utilities, the lay down yard, and telecom. Staffing covers owner salary at market rate, the fractional CFO, in house accounting, and admin. Benefits go in for office staff only, because field benefits belong in job cost. Software and services covers accounting, the job costing platform, estimating software, the website, and IT. Equipment maintenance splits, with general upkeep to overhead and project specific damage to job cost. Then add business taxes, dues, and licenses, and add a scenario plan for the slow season when fixed costs don't drop with revenue.
Use the revenue you expect to do this year, or better, a conservative estimate of it. If you project $6M and do $4M, your overhead rate was understated all year. It's always better to be slightly conservative on the revenue denominator than to underprice six months of bids.
The overhead rate is a CFO level monthly task. Every time a cost component moves, whether that's a new hire, a software subscription, or a workers comp renewal, the rate updates before the next bid goes out. The published industry figures are Jones Maresca and Company's 8 to 15 percent total indirect cost for construction as a whole and CFMA's 11.8 percent SG&A across all respondents, and both describe the market rather than set a target. The rate for your trade and band is on /construction-overhead-rates-by-trade. When your rate drifts above your own trade benchmark, the CFO works out what moved and whether it's a cost structure problem or a revenue base problem.
FLAT MONTHLY FEE. NO SURPRISES.
Three tiers, priced by your trailing twelve month revenue. Which one you're in depends on how much of the work you want off your desk. No hourly billing, no payroll, and no add-ons.
