pWin (Probability of Win)
pWin, short for probability of win, is a capture management metric that expresses a bidder's estimated likelihood of winning a specific opportunity, usually as a percentage. Teams use pWin to prioritize pursuits, support go/no-go decisions, and direct proposal resources toward the opportunities with the strongest expected return.
In practice
pWin is most established in government contracting, where capture managers track opportunities for months or years before a solicitation is released, but commercial bid teams use the same idea. The score is assigned early, then revised as the team learns more about the customer, the competition, and its own position.
Rather than a single formula, most organizations score a set of factors, such as customer relationship, incumbency, solution fit, past performance, price position, and strength of competition, then weight and combine them into an overall percentage. The value lies less in the precise number than in the discipline of the review and how the number moves over time.
For example, a bid team might hold an opportunity at a low pWin until meetings with the customer and a signed teaming agreement improve its position, then raise the score and commit senior proposal resources ahead of the RFP.

FAQ
Frequently asked questions
How is pWin calculated?
There is no universal formula. Common approaches score weighted factors such as relationship strength, solution fit, incumbency, past performance, and price competitiveness, or use structured group judgment from capture and sales leaders. Scores are updated at defined reviews as new intelligence arrives.
What is a good pWin?
It depends on the cost of bidding and the organization's pipeline strategy. Many teams set an internal threshold below which they will not bid without a strategic reason, since effort spent on low-probability pursuits crowds out winnable ones. The threshold itself varies by company.
Who owns the pWin number?
Typically the capture manager or pursuit lead proposes pWin, and a review board or sales leadership challenges and approves it. Shared ownership matters, because a number set by one optimistic stakeholder tends to inflate, which distorts forecasts and bid decisions.
