How do you calculate win-rate margin impact?

Divide the number of quotes won at or above target margin by the total quotes submitted, then multiply by 100. With 8 margin-protected wins out of 250 quotes, the rate is 8 ÷ 250 × 100 = 3.2%.

What is a good margin-protected win rate?

For build-to-print machine shops, 25-35% of submitted quotes converting at target margin is healthy; under 10% usually signals either bidding the wrong work or pricing above the market. The 3.2% in the example is far below any healthy benchmark.

Why is my gap to target so large?

The gap is your rate minus your target. At a 3.2% realized rate against a 95% target, the gap is 91.8 points — a target of 95% is almost certainly mis-set, since no shop wins 95% of all quotes at full margin.

Is this the same as overall win rate?

No. Overall win rate counts any order won; this metric only counts wins that held target margin, so it filters out jobs you bought through discounting and shows true quoting quality.

Should I count quotes that were never decided?

Exclude quotes still open or no-quoted; the denominator should be quotes that reached a win/loss decision in the period, or the rate will be artificially deflated by a backlog of pending RFQs.

How can I improve a low margin-protected win rate?

Qualify RFQs harder before estimating, walk away from price-only buyers, and tighten cost models so quoted margin matches realized margin — chasing every RFQ dilutes the win rate and the estimating team's capacity.

Manufacturing Sales Engineering, Estimating & Quoting Operations calculator

Win-rate margin impact Calculator

Win-rate margin impact tracks how many of your submitted quotes actually convert into orders that hold target margin, expressed as a percentage of total quotes sent. Estimating managers and sales engineers in custom and contract manufacturing use it to separate volume of wins from quality of wins — a 40% raw win rate means little if most of those jobs were bought below cost to fill capacity. By comparing the realized rate against a target, the calculator surfaces whether your shop is discounting its way to a full schedule. It is one of the fastest signals that quoting discipline is slipping before it shows up in the P&L.

What this calculator does

Estimate win-rate margin impact for manufacturing sales engineering, estimating and quoting operations using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.
Use it when win-rate margin impact in manufacturing sales engineering, estimating and quoting operations needs a clean rate and gap-to-target you can put on a tier board.
It computes the percentage of total submitted quotes that were won at or above target margin, plus the point gap between that rate and your target win rate.

Formula used

Win-rate margin impact rate = win-rate margin impact count ÷ total win-rate margin impact population × 100
Win-rate margin impact gap to target = win-rate margin impact rate - target win-rate margin impact rate

Inputs explained

Quotes won at or above target margin:
Total quotes submitted in period:
Target margin-protected win rate:

How to use the result

Use it monthly or per quoting cycle to review whether margin-protected wins are tracking to plan and to compare estimators, product lines, or customer segments.
The metric treats every quote equally, so one $2M structural job and one $4k bracket job count the same — weight by dollar value if your quote mix is lopsided.

Current U.S. benchmarks

The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
