A PWin (Probability of Win) score is the most important go/no-go metric in federal business development. This guide explains what PWin is, what factors affect it, how to calculate it, and how AI-powered PWin scoring tools help GovCon firms make better bid decisions.
A PWin score is a numerical estimate — typically expressed as a percentage from 0–100% — of how likely your firm is to win a specific federal contract. It is calculated before you write the proposal, to help you decide whether to invest your B&P (bid and proposal) budget in pursuing the opportunity.
A PWin score of 75% means your team believes there's a 3-in-4 chance of winning. A score of 20% means you're unlikely to win — and should consider passing or developing your position before formally bidding.
Incumbents win recompetes 70–80% of the time. Knowing whether you're the incumbent — or competing against one — is the single highest-weight factor in any PWin calculation.
Have you worked with this contracting office or program office before? Relationship strength — from cold to close — significantly affects your ability to shape requirements and understand evaluator preferences.
How closely does your past contract performance match the scope, size, and complexity of the new requirement? A strong past performance match is a critical PWin driver.
How many firms are likely to bid? A 4-bidder competition is very different from a 12-bidder one. Fewer qualified competitors raises your PWin; more lowers it.
Is the estimated contract value in your firm's sweet spot? Bidding too large or too small for your capacity is a PWin penalty — evaluators look for appropriately sized contractors.
Do you have a unique technical capability, proprietary methodology, or patented solution that competitors can't match? True differentiation is a powerful PWin multiplier.
