Win Rate
The proportion of submitted bids you convert.
Win rate is the proportion of tenders a supplier bids for that it goes on to win, usually expressed as a percentage of bids submitted (or sometimes of bid/no-bid opportunities considered) over a given period. It is one of the main internal metrics bid teams use to judge whether their approach to selecting and writing bids is working.
Calculating it in a way that's actually useful
A raw win rate — wins divided by total bids submitted — is a reasonable starting point, but it hides useful detail unless broken down further. Two suppliers with identical overall win rates can have very different underlying pictures: one winning consistently across a wide range of opportunity types, another winning almost entirely through one strong existing relationship and losing everything else.
Segmenting win rate by contract value, sector, new business versus incumbent renewal, and lead time between notice and deadline usually reveals more than the headline number alone.
- Overall win rate: wins / total bids submitted
- Win rate by opportunity type (new business vs. renewal/incumbent)
- Win rate by contract value band
- Win rate by sector or buyer type
- Win rate against average feedback score, where feedback is available
Why external benchmarks are unreliable
Published 'industry average' win rate figures vary hugely depending on how they're defined, which sectors and contract sizes they cover, and how selectively the sample of bidders applied a bid/no-bid filter before submitting. A supplier that bids selectively will show a different rate to one that bids indiscriminately, without either approach necessarily being wrong.
The more useful comparison is a supplier's own win rate over time, and how it changes after specific process improvements — introducing storyboarding, tightening bid/no-bid discipline, or adding a red review stage — rather than comparison against an external number of uncertain provenance.
Using win rate to drive improvement
A falling or stagnant win rate is worth investigating alongside feedback from unsuccessful bids, since the same underlying number can result from very different causes: weak bid/no-bid selection, poor writing quality, uncompetitive pricing, or genuinely tougher competition in a given period.
Frequently asked questions
- What counts as a good win rate?
- There is no reliable universal benchmark, since definitions and bidding strategies vary too widely across suppliers and sectors. It is more useful to track a supplier's own win rate over time and against its own bid/no-bid discipline than to compare against an external figure.
- Should win rate be measured by number of bids or by value?
- Both are useful and answer different questions. Win rate by number shows how often submissions succeed; win rate by value shows whether the wins are commercially significant relative to what was pursued. Tracking both gives a fuller picture.
- How can a supplier improve a low win rate?
- Start by requesting and reviewing evaluator feedback on lost bids to identify recurring weaknesses, tighten bid/no-bid discipline to avoid pursuing poor-fit opportunities, and check pricing competitiveness alongside the quality of written responses before assuming the writing alone is the cause.
