OVERHEAD RATE

WINNING TOO MANY BIDS IS COSTING YOU MONEY.

QUICK ANSWER

Winning more than 35% of competitive construction bids almost always means the overhead rate in your bids is too low. Every job you win is underpriced by the difference between the rate in the bid model and your real overhead rate.

Most contractors worry about not winning enough work. Winning more than 35% of competitive bids is the opposite problem, and it costs more than losing bids does, because a lost bid costs you nothing but the time it took to price. An underpriced won job costs you the shortfall on every hour and every dollar of material for the length of the job. Then it repeats on the next one, because the rate that produced it hasn't changed. Busy and underpriced is the most expensive place a subcontractor can be.

THE DEFINITION

WHAT IT MEANS.

The overhead rate is SG&A divided by revenue, the percentage every bid has to carry to cover what it costs to run the business.

The win rate is the cheapest diagnostic in the business, because you already have the data. If you're winning more than a third of the competitive work you chase, your price is consistently below the market, and the most common reason is an overhead rate that doesn't carry what your overhead really costs.

WHY THE RATE IS TOO LOW

WHERE THE OVERHEAD WENT MISSING.

01

The overhead rate was set once and never updated

You set your overhead rate when you started bidding. Since then you hired a PM, bought equipment, added insurance, and moved into a larger shop. The overhead grew and the rate in the bid model didn't. Every bid since that last hire is underpriced by the difference, on every single job, with nothing in any report pointing at it.

02

Owner compensation is missing or understated

This is the most common overhead understatement we find. The owner books a nominal salary of $60,000 to $80,000 to hold down payroll taxes and takes draws when cash allows, so the overhead rate gets calculated on $70,000. The real value of the owner's role at $5M in revenue is $140,000 to $170,000, which leaves the bid model underfunded by $70,000 to $100,000 a year on every bid.

03

Equipment depreciation isn't in overhead

Equipment depreciates whether it's working or sitting. An excavator with $4,200 a month in ownership cost has to be covered by the overhead rate or by job level equipment cost codes. If it's booked to a balance sheet account and never hits the P&L, the overhead rate is understated by that full amount and every bid carries the error.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

What a 3 point overhead shortfall costs

At $2M in revenue, a 3 point shortfall is $60,000 a year and $300,000 over five years. At $3M it's $90,000 a year and $450,000 over five years. At $5M it's $150,000 a year and $750,000 over five years. At $8M it's $240,000 a year and $1,200,000 over five years. At $10M it's $300,000 a year and $1,500,000 over five years.

And 3 points is the mild case

SPM finds 5 to 8 point shortfalls at engagement start on most clients whose overhead rate hasn't been recalculated in two or more years. The high win rate is the symptom that gives it away before anybody opens the P&L, which is why it's worth counting your bids before you go looking for the cause.

HOW SPM FIXES IT

HOW TO CORRECT THE RATE RIGHT NOW.

Pull SG&A from the last 12 months of P&L

Everything that's not a direct job cost belongs here: officer compensation, admin salaries, rent, insurance, the vehicle fleet, equipment depreciation, professional services, and technology. If something sits in COGS that shouldn't, like owner salary inside direct labor or a personal vehicle inside equipment, move it to SG&A for this calculation.

Add market rate owner compensation if it's missing

If you're paying yourself $70,000 and the market rate for your role at your revenue level is $150,000, add $80,000 to SG&A before calculating the rate. The overhead rate has to reflect what the business costs to run, not what you chose to pay yourself in a tight year.

Divide corrected SG&A by revenue

That percentage is your real overhead rate. Compare it to what's sitting in your bid model right now. The overhead rate calculator will run the same math in a structured format if you want it laid out line by line.

Update the bid model immediately, not next quarter

The shortfall has been running since the last recalculation, however long ago that was. Every bid submitted at the wrong rate is a job underpriced. The correction applies to every new bid going forward, starting with the one sitting on your desk today.

Recalculate after every significant hire or operational change

Every PM, estimator, or admin hire adds $60,000 to $100,000 in SG&A. The rate needs updating at the time of hire, not eighteen months later when you notice margin compression. SPM recalculates the rate at engagement start and reviews it monthly as part of the close.

COMMON QUESTIONS

FREQUENTLY ASKED.

It almost always means your overhead rate is too low. In competitive bidding you win when your price is lower than your competitors' prices. If you're consistently winning more than 35% of competitive bids, your price is consistently lower, and the most common reason is an overhead rate that doesn't capture what your overhead really costs. You're subsidizing every job you win out of your own net income.
Three steps. First, calculate your real overhead rate by pulling SG&A from the last 12 months of P&L and dividing by revenue, including full owner compensation at market rate, equipment depreciation, and all vehicle costs. Second, compare that figure to what's in your bid model. Third, if the real rate is higher, update the bid model and apply the corrected rate to every new bid going forward.
Civil and grading contractors typically run 12 to 16% overhead. Concrete contractors run 11 to 15%. Electrical contractors run 14 to 18%. SWPPP and erosion control run 12 to 15%. Masonry runs 12 to 15%. Framing and drywall run 11 to 14%. The right rate for your business is your own SG&A divided by your own revenue, not an industry benchmark.
Yes, directly. Winning too many bids means every job is underpriced. Underpriced jobs produce less gross margin than you need to cover overhead, so the business works harder, takes on more jobs, and the shortfall compounds. A contractor winning 50% of bids at a 3 point overhead shortfall is generating $150,000 a year less gross profit than they should on $5M in revenue, and wondering why cash is always tight despite being busy.
Three tiers, and which one you are in depends on how much of the work you want off your desk. Core is where you stop guessing: job costing built against the way you estimate, a 13 week cash forecast, monthly WIP, and a monthly meeting that ends in decisions, while your bookkeeper keeps doing the books. Executive is where you stop touching the books, because we run the bookkeeping and the controllership as well. Strategic is where every job shows its margin while it is still running, because the job costing and WIP platform is set up and managed for you. No payroll. No scope gaps.
