Construction Bid Win Rate Closing Rate Guide

TL;DR: A construction subcontractor's bid win rate is a diagnostic tool for their overhead rate. Winning more than 35% of competitive bids almost always means the overhead rate in bids is too low. The jobs are underpriced. The contractor wins more work, works more hours, and ends up with less cash. The fix is recalculating the overhead rate from the actual P&L — pulling SG&A from the last 12 months, dividing by revenue, and comparing to what's in the bid model. A 5-point correction on $5M in revenue is $250,000 per year in recovered margin.

The Diagnostic

What Your Win Rate Is Actually Telling You

A bid is an auction. You name a price for a defined scope of work. Your competitors do the same. When you win, it means your price was lower than theirs — or your reputation earned you a premium that offset a higher price. For competitive bid work where the award goes to the lowest qualified bidder, consistently winning more than 35% of bids means your price is consistently lower than your competitors' prices. The most common reason: your overhead rate is lower than your actual overhead.

Win Rate Too High (>35%)

Overhead rate in bids below actual SG&A

Every job won is underpriced by the gap

More work, more hours, less cash

P&L shows profit, bank account disagrees

Fix: recalculate overhead rate from P&L today

Win Rate Too Low (<15%)

Overhead rate may be too high — or overstated

Bidding outside your competitive range

Market pricing shifted, rates haven't followed

Wrong GC relationships for your trade and size

Fix: audit overhead rate and bid selectivity

The Overhead Rate Connection

How a Wrong Overhead Rate Creates a High Win Rate

Overhead rate is the percentage of revenue needed to cover all business overhead — salaries, rent, insurance, vehicles, equipment depreciation, owner compensation. If the overhead rate in your bids is 10% and your actual overhead is 16%, you're submitting bids that underfund overhead by 6 points on every job. Your competitors, pricing at their actual overhead, are submitting higher bids. You win more. You make less.

Calculate your real overhead rate right now. Pull SG&A from your last 12 months of P&L — every expense that isn't direct job cost. Divide by total revenue. That percentage is your real overhead rate. If it's higher than what's in your bids, every job you win since the last time you updated your rate has been underpriced.

Include everything in SG&A. The most common errors: owner compensation below market rate (or not included at all), equipment depreciation booked elsewhere, vehicle costs split between direct and overhead, and health insurance paid through a separate account. Every one of these understates overhead and understates the rate needed in bids. Use the overhead rate calculator to run the numbers.

Update the bid model immediately. Once the corrected rate is calculated, it goes into the bid model and applies to every bid going forward. Not next quarter. Not after the next job closes. Immediately. The overhead gap has been running for however long since the last recalculation — every bid submitted at the wrong rate is a job underpriced.

Track win rate by work type, not overall. Your win rate on negotiated work with known GCs will be higher than your win rate on competitive bids against five other subs. Blending them masks the signal. Track competitive bid win rate separately — that's the number that tells you whether your pricing is at market.

Recalculate after every significant hire. Every PM, estimator, or office staff member adds $60,000–$100,000 in annual overhead. The overhead rate in bids needs to be updated immediately after every significant hire. Most contractors update it when they feel the pain — which is 6–18 months after the hire, after the margin compression has already accumulated.

Benchmark

Win Rate Benchmarks by Trade

These ranges reflect competitive bid work — not negotiated or sole-source work. Win rates on negotiated work are typically higher and reflect relationship value rather than pure pricing.

Trade	Healthy Win Rate	Too High (Check Overhead)	Too Low (Check Pricing)
Civil / Excavation / Grading	20–35%	Above 40%	Below 15%
Concrete / Masonry	22–38%	Above 42%	Below 15%
Electrical (Commercial New)	18–30%	Above 35%	Below 12%
SWPPP / Erosion Control	25–45%	Above 50%	Below 18%
Framing / Drywall	22–38%	Above 42%	Below 15%
Paving / Sitework	20–35%	Above 40%	Below 12%

FAQ

Frequently Asked Questions

What is a good bid win rate for construction subcontractors?

A healthy bid win rate for commercial subcontractors is 20–35% depending on trade and market. If you're winning more than 35% of your bids, your overhead rate is almost certainly too low and you're underpricing every job you win. If you're winning less than 15%, your overhead rate may be too high, your pricing may be out of step with market conditions, or you're bidding work outside your competitive advantage. The win rate is a diagnostic tool — not a goal in itself.

Why does winning too many construction bids mean my overhead rate is wrong?

Bids are essentially an auction. If you're winning more bids than your competitors on similar scope, it usually means your price is lower than theirs — and the most common reason your price is lower is that your overhead rate doesn't capture your actual overhead costs. A 5-point overhead gap on $5M in revenue is $250,000 per year in underpriced margin. You win more bids. You work more hours. You make less money. That's the overhead rate trap.

How do I calculate my bid-hit ratio?

Bid-hit ratio = jobs won divided by jobs bid over a given period, expressed as a percentage. Track this by trade type and GC relationship — your win rate on negotiated work will differ from competitive bid work, and your win rate with a known GC will differ from cold bids. The number that matters is your competitive bid win rate on similar-scope work. If that number is above 35%, recalculate your overhead rate before bidding another job.

What should I do if my bid win rate is too high?

Recalculate your overhead rate from the P&L — pull SG&A from the last 12 months, divide by revenue. Compare to what's in your bids. If the real rate is higher than the bid rate, update the bid model immediately and apply the corrected rate to every bid going forward. If the real rate matches the bid rate and you're still winning too many bids, consider whether your direct cost estimates are also below market — labor burden, material pricing, and subcontractor costs all shift over time.

How does bid win rate connect to cash flow problems?

A too-high bid win rate means you're underpricing every job. Underpriced jobs produce less gross margin than the estimate assumed. That margin gap has to come from somewhere — usually operating cash or the line of credit. The contractor works harder, wins more work, and ends up with tighter cash and less profit. The fix isn't winning fewer bids — it's correcting the overhead rate so the margin on every job reflects actual costs.
