ESTIMATING, BID STRATEGY

WINNING TOO MANY BIDS IS A MARGIN PROBLEM.

QUICK ANSWER

A healthy bid win rate for a commercial subcontractor on competitive work is 20 to 35%. Win rates above 40% are a warning sign rather than a success metric. If you're winning more than one in three competitive bids you're probably bidding below market. You're winning on price, and cheap means thin margins, so the growth you're generating is producing losses nobody has recognized yet.

Commercial construction is competitive bidding, so the market sets the price and your number either sits inside it or below it. Winning more than a third of what you chase means you're consistently the low number, and there are only two explanations for that. Either you're cheap on purpose with full knowledge of your cost, or your cost model is wrong and you don't know it. The second is far more common, and the usual culprit is an overhead rate carried forward in the bid model that no longer covers what the office costs to run.

THE DEFINITION

WHAT IT MEANS.

A bid win rate is the share of the competitive bids you submit that you're awarded, and above 35% it's telling you your price sits below the market.

The win rate is the cheapest diagnostic in the business because you already own the data. Two causes account for most high win rates: an overhead rate that hasn't been rebuilt from real financials, and cost categories missing from the estimate entirely. Both produce the same result, which is a bid that reads competitive because it's incomplete.

WHAT OVERPRICED WIN RATES LOOK LIKE BY TRADE

SAME SYMPTOM, DIFFERENT MISSING COST.

01

Concrete, winning on buried costs

Concrete subs winning 50% or more of their bids are usually missing real costs rather than beating competitors: small tools, pump time, finishing labor at overtime, and washout fees. The bid reads lean because the estimate is incomplete. The 30% to 40% profit they think they're making comes in at 3% to 5% once the buried costs surface.

02

Civil, the equipment subsidy

Civil contractors with high win rates are often subsidizing bids with unpriced equipment, either 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.

03

Electrical, the work type blind spot

Electrical subs commonly win everything in one work type and lose everything in another, taking rough-in at a loss and losing trim bids they would have profited on, because both carry the same blended markup. A lopsided win rate by work type is the diagnostic on its own. It means the cost model is wrong in opposite directions at the same time.

04

SWPPP and service trades, the utilization trap

T&M and service trades win too much when their rates are built on busy month math. A rate that pencils at 90% utilization loses money at the 60% the year averages out to. A high win rate, a full schedule, and an empty bank account together are the signature of a utilization blind rate sheet.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The win rate bands

Below 15% means you're bidding too high or chasing the wrong market. 20% to 35% is the healthy competitive range. 35% to 50% is the watch zone where the overhead rate needs checking, and above 50% you're almost certainly bidding below cost.

41% down to 28%, with margin up

After one 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 those was the profit.

Negative 1% to 11% net

A $6.7M civil contractor was bidding 10% overhead against a real 30%, which means losing 1% on every job before mobilization. Corrected to a real 18% overhead with competitive profit on top, the same bid volume produced 11% net. Same market, same competitors, different math.

$203K in week one

A verified concrete client at $4.9M was bidding off a 5% book overhead against a real number of 12%, winning constantly and netting 3.3%. The correction started with collecting $203K of overdue AR in week one, then repricing the forward work. The next year brought $1.3M less revenue, more profit, and $130K in first ever profit sharing.

HOW SPM FIXES IT

WHAT HAPPENS WHEN THE RATE GETS CORRECTED.

Calculate the real overhead rate from expense data, then compare it to the bid

The first step is total annual overhead divided by annual revenue, pulled from real expense data and not from what the bid model has always said. The second step is comparing that figure to what's sitting in the estimates today. Most growing subcontractors find the estimate uses 10 to 12% while the real rate is 18 to 24%, and that difference is the margin disappearing on every job.

Reprice forward work and accept the lower win rate

Some of the work stops coming in, and that's the goal rather than a side effect. Work won at prices that don't cover overhead and profit is worse than work you never won at all. A subcontractor who wins 22% of competitive bids at correct margin makes more money than one who wins 55% at margin that doesn't cover the office.

Split the win rate by work type, not just in total

A blended win rate hides the diagnosis. Winning nearly everything in one work type while losing nearly everything in another means the cost model is wrong in both directions, and the blended markup is what conceals it. Splitting the win rate by work type points straight at which part of the estimate is off.

Watch the margin on the work you win, not the rate itself

Win rate is the smoke and margin is the fire. The rate tells you to go looking, and the gross margin on the jobs you won tells you what you find. A subcontractor tracking both together stops guessing about whether the last repricing worked.

COMMON QUESTIONS

FREQUENTLY ASKED.

Yes, on negotiated work with long term GC relationships where your track record commands a preferred position. On open competitive bids where several subcontractors submit prices, efficiency turns up as a lower cost to execute rather than as a 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 the real overhead rate from expense data, meaning total annual overhead divided by annual revenue. Second, compare it to what's in the estimates. Most growing subcontractors find the estimate uses 10 to 12% and the real rate is 18 to 24%. That difference is the margin that disappears on every job without anybody noticing until year end.
Some of it, which is the point. 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 doesn't cover overhead. The first one has a profitable business and the second one has a revenue number and a cash problem.
GC relationships built entirely on being the cheapest bid are a standing discount. Experienced GCs carry subs they trust at competitive but real prices, because blown schedules and failed subs cost them far more than a few percent on the bid. When 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 line of credit, and the GCs stayed.
20 to 35% on competitively bid work is the healthy band. Below 20% you're either overpriced for your market or bidding the wrong work, and both are 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 is the margin on the work you win.
