A healthy bid win rate for a commercial subcontractor on competitive work is 20 to 35%. Win rates above 40% are a warning sign — not a success metric. If you are winning more than one in three competitive bids, you are probably bidding below market. You are winning because you are cheap, not because you are the best. And cheap means thin margins, which means the growth you are generating is actually generating losses you have not fully recognized yet.
WIN RATE ABOVE 35%? YOUR OVERHEAD RATE IS PROBABLY WRONG.

Why High Win Rate Signals Low Margins
MARKET PRICE IS SET BY WHAT COMPETITORS CHARGECommercial construction pricing is competitive. GCs get multiple bids on most scopes. The market has established a range for what each trade's work costs — a range that reflects the real cost of performing the work at a reasonable margin. A subcontractor consistently winning at prices below market is pricing below that range. Which means they are pricing below the cost of doing the work correctly.
THE MOST COMMON CAUSE: WRONG OVERHEAD RATEMost subcontractors who bid too low do so because the overhead rate in their estimate is wrong — understated relative to actual overhead. If actual overhead is 22% but the estimate uses 10%, every bid is absorbing 12 points of overhead without charging for it. The job feels profitable during execution. The annual P&L shows why it wasn't.
THE SECOND MOST COMMON CAUSE: MISSING COST CATEGORIESSuperintendent time. Small tools budget. Project-specific insurance. Permit fees. Equipment idle time. Each of these is a real cost that belongs in the estimate. When they are missing — lumped into overhead or excluded entirely — the estimate understates the true cost of the work and the bid comes in below market without the estimator understanding why they keep winning.
What a Healthy Win Rate Looks Like
<15%
Bidding Too High or Wrong Market
20–35%
Healthy Competitive Range
35–50%
Watch Zone — Check Overhead Rate
>50%
Almost Certainly Bidding Below Cost
These ranges apply to competitive bids — multiple subcontractors bidding the same scope. Negotiated work with preferred GC relationships should have higher win rates. The competitive win rate is the signal.
WHAT OVERPRICED WIN RATES LOOK LIKE BY TRADE.
Concrete: Winning on Buried Costs
Concrete subs winning 50%+ of bids are usually missing real costs, not beating competitors — small tools, pump time, finishing labor at overtime, washout fees. The bid looks lean because the estimate is incomplete. The 30–40% profit they think they're making lands at 3–5% after the buried costs surface.
Civil: The Equipment Subsidy
Civil contractors with high win rates are often subsidizing bids with unpriced equipment — machines billed to jobs at rates below true cost basis, or idle time absorbed silently in overhead. Every win at a subsidized rate digs the hole deeper. The market isn't validating the price. It's accepting a donation.
Electrical: The Work-Type Blind Spot
Electrical subs commonly win everything in one work type and lose everything in another — winning rough-in at a loss and losing trim bids they'd profit on, because both carry the same blended markup. A lopsided win rate by work type is the diagnostic: it means the cost model is wrong in opposite directions.
SWPPP & Service Trades: The Utilization Trap
T&M and service trades win too much when rates are built on busy-month math. A rate that pencils at 90% utilization loses money at the 60% the year actually averages. High win rate, full schedule, empty bank account — the signature of a utilization-blind rate sheet.
WHAT HAPPENS WHEN THE RATE GETS CORRECTED.
41% → 28%
Win rate down. Margin up. After one SPM client corrected their overhead rate and repriced, win rate fell from 41% to 28% — squarely into the healthy band — while gross margin climbed from 19% to 26%. The bids they stopped winning were the ones priced below cost. Losing them was the profit.
-1% → 11%
From paying to work to getting paid. A $6.7M civil contractor was bidding 10% overhead against a real 30% — losing 1% on every job before mobilization. Corrected to a real 18% overhead with competitive profit, the same bid volume produced 11% net. Same market. Same competitors. Different math.
$203K
Week one of fixing the underbid pattern. A $4.9M concrete sub bidding off a 5% book overhead (real number: 12%) had been winning constantly and netting 3.3%. The correction started with collecting $203K of overdue AR in week one, then repricing forward work. The next year: $1.3M less revenue, more profit, and $130K in first-ever profit sharing.
Frequently Asked Questions
Yes — on negotiated work with long-term GC relationships where your track record commands a preferred position. On open competitive bids where multiple subcontractors submit prices, efficiency shows up in lower cost-to-execute rather than lower bid price. A genuinely efficient subcontractor should still be pricing at market and winning 20 to 35% of competitive bids — not winning 60% by being the lowest price every time.
Two steps. First, calculate actual overhead rate from real expense data — total annual overhead divided by annual revenue. Second, compare it to what is in the estimates. Most growing subcontractors find the estimate uses 10 to 12% and the actual rate is 18 to 24%. The gap is the margin that disappears on every job without anyone noticing until year-end.
Some of it — which is the goal. Work won at prices that don't cover overhead and profit is worse than not winning that work. A subcontractor who wins 22% of competitive bids at correct margin makes more money than one who wins 55% at margin that does not cover overhead. The first has a profitable business. The second has a revenue number and a cash problem.
GC relationships built entirely on being the cheapest bid aren't relationships — they're a standing discount. Experienced GCs carry subs they trust at competitive-but-real prices because blown schedules and failed subs cost them more than a few percent on the bid. When SPM clients reprice, they typically lose the GCs who only ever wanted the donation and keep the ones worth keeping. One client's repriced book of work came with $65K in bonuses and a paid-off LOC. The GCs stayed.
20–35% on competitively bid work is the healthy band. Below 20%, you're either overpriced for your market or bidding the wrong work — both worth diagnosing. Above 35% sustained, you're almost certainly the cheapest, and the question is whether you're cheap on purpose with full cost knowledge or cheap by accident through a broken overhead rate. Negotiated and relationship work runs higher legitimately. The number to watch isn't the rate itself — it's the margin on the work you win. Win rate is the smoke. Margin is the fire.
IS YOUR WIN RATE TELLING YOU YOUR OVERHEAD RATE IS WRONG?
If you win more than 35% of competitive bids consistently, the first call calculates your actual overhead rate and shows you the gap between what you are charging and what the work actually costs.
