Do you actually know your bid win rate?

Win rate = bids won ÷ bids submitted × 100. If you sent 40 bids and won 12, that is a 30% win rate. This calculator runs it instantly and compares it to typical benchmarks, then shows the revenue you won and the margin gap between your target and what the math actually delivers. Most contractors guess their win rate; the few who measure it find the leak fast.

Est. 25-50% is a common range depending on trade, bid quality, and how warm the lead was before you quoted. Referral and repeat work closes far higher; cold bid-board work much lower. A low win rate is rarely about price alone — it is usually slow response, a quote that looks unprofessional, or weak trust signals. All three are fixable before you cut your margin.

The three biggest leaks, in order: speed (the first credible bid usually wins), trust (no reviews or a weak website makes you the risky choice), and presentation (a sloppy quote signals sloppy work). Price is fourth. Most contractors blame price and start discounting, which destroys margin without fixing the real problem. The calculator shows you the cost of that low win rate in real dollars.

Usually no. Cutting price to lift win rate trades margin for volume and often leaves you busier but poorer. A 5-point win-rate gain from faster follow-up and better trust signals is worth far more than the same gain from discounting. Raise your win rate by being the easy, credible choice — not the cheap one. The margin-gap row above shows what discounting really costs.

Every percentage point of win rate is revenue you already paid to chase — your time estimating, site visits, and follow-up are sunk whether you win or lose. If you submit 50 bids worth $8,000 each, lifting win rate from 25% to 35% adds five jobs and $40,000 in revenue with zero extra leads. The calculator quantifies exactly that gap for your numbers.

The margin gap is the difference between the margin you target and the margin left after overhead is loaded onto your bids. If you target 20% but overhead eats more than you priced in, you are quietly winning unprofitable work. This calculator loads your overhead percentage and shows whether your won revenue actually clears your target margin or just looks like it does.

Respond first, look credible, and follow up. Est. the first contractor to send a professional quote wins a large share of jobs before competitors even reply. A fast, trustworthy web presence and strong local reviews do more for win rate than any discount. That is the channel I build — so you win on credibility, not on being the cheapest.

Marketing raises both how many bids you get to submit and how warm they are when you quote. A lead that found you ranking locally and read your reviews is far more likely to sign than a cold bid-board request. Use this calculator to see your current win rate and revenue gap, then I improve the lead quality and trust signals that lift the rate. They compound.

Mandeep Singh, founder of Sprout Sage Solutions. I build web design, SEO, and local marketing for contractors and home-service businesses — founder-led, transparent pricing, no contracts. I built this because most contractors I talk to can quote a job in their sleep but have never measured the win rate that decides whether all that estimating pays off.

Book a free 30-minute audit. I review your website and local search presence live, show you where bids are being lost to faster or more credible competitors, and tell you the channel mix that lifts both lead quality and win rate. No pitch deck, no contract. Local SEO from $1,000/mo, sites from $500.
