How to Calculate Win Rate

Win rate measures the percentage of sales opportunities that convert to closed deals. Learn the win rate formula, segmentation strategies, and how to improve close rates.

Win rate is the percentage of sales opportunities that result in closed-won deals, measuring how effectively your sales team converts prospects into customers. It is calculated by dividing the number of won deals by the total number of closed opportunities (both won and lost) over a specific period. Win rate is a fundamental sales effectiveness metric that informs forecasting, pipeline management, and sales strategy decisions.

Win Rate Formula

Win Rate = (Closed-Won Deals / Total Closed Deals) x 100

Where Total Closed Deals = Closed-Won + Closed-Lost

Note: Open opportunities are excluded from the calculation - win rate only measures completed sales cycles.

Step-by-Step Calculation

Step 1: Define the Time Period

Select a consistent measurement period - monthly, quarterly, or annually. Ensure you have sufficient closed deals for statistical significance.

Step 2: Count Closed-Won Deals

Identify opportunities with a closed-won outcome during the period:

  • Deal marked as won
  • Contract signed
  • Revenue recognized (depending on your definition)

Step 3: Count Total Closed Deals

Sum closed-won and closed-lost opportunities:

Total Closed = Closed-Won + Closed-Lost

Exclude:

  • Open opportunities (still in progress)
  • Disqualified opportunities (if your definition excludes them)
  • No-decision outcomes (clarify how to treat these)

Step 4: Calculate Win Rate

Win Rate = (Closed-Won / Total Closed) x 100

Example Calculation

Quarterly win rate for a sales team:

OutcomeCount
Closed-Won45
Closed-Lost135
Still Open80 (excluded)
Total Closed180
Win Rate = (45 / 180) x 100 = 25%

This team closes 1 in 4 qualified opportunities that reach a final decision.

Win Rate Variations

Opportunity-Based Win Rate

Standard calculation - percentage of opportunities won:

Opportunity Win Rate = Won Deals / Total Closed Deals x 100

Value-Based Win Rate

Weighted by deal value - shows revenue capture efficiency:

Value Win Rate = Won Deal Revenue / Total Closed Deal Revenue x 100

A team might have 25% opportunity win rate but 40% value win rate if they win larger deals more often.

Stage-Based Win Rate

Win rate from specific pipeline stages:

Stage Win Rate = Deals Won from Stage / Deals Entering Stage x 100

Example: 60% of deals that reach Proposal stage ultimately close.

Competitive Win Rate

Win rate against specific competitors:

Competitive Win Rate = Deals Won vs Competitor / Total Competitive Deals x 100

Identifies competitive strengths and weaknesses.

Win Rate Benchmarks

SegmentTypical Win Rate
Enterprise B2B15-25%
Mid-Market B2B20-30%
SMB B2B25-40%
Transactional/Inbound30-50%
Complex/Consultative10-20%

Win rate expectations vary significantly. A complex enterprise sale with 18% win rate may outperform a simple SMB sale at 35% in revenue terms.

Interpreting Win Rate Changes

Win Rate Increasing

Positive indicators:

  • Better qualification
  • Improved sales execution
  • Stronger competitive position
  • Better product-market fit

Potential concerns:

  • Sandbagging pipeline (only pursuing easy wins)
  • Insufficient pipeline volume
  • Over-discounting to close

Win Rate Decreasing

Potential causes:

  • Competitive pressure
  • Poor qualification
  • Sales skill gaps
  • Product issues
  • Market changes

Investigate closed-lost reasons to identify root causes.

Common Win Rate Mistakes

Mistake 1: Including Open Opportunities

Win rate should only include resolved opportunities. Including open deals understates win rate and changes as deals close.

Mistake 2: Inconsistent Lost Definitions

When does a lost deal get marked closed-lost? If reps delay closing out losses, win rate is artificially inflated. Enforce pipeline hygiene.

Mistake 3: Ignoring No-Decisions

Prospects who go silent or defer indefinitely are often not marked lost. Decide how to treat no-decisions - they represent real sales effort that didn't convert.

Mistake 4: Small Sample Sizes

Monthly win rate for a rep with 5 closed deals has high variance. Use longer periods or team-level metrics for statistical reliability.

Mistake 5: Aggregate-Only Analysis

Overall win rate hides important variation. Segment by rep, product, source, competitor, and deal size for actionable insights.

Win Rate Segmentation

By Sales Rep

RepWonLostWin Rate
Rep A184230%
Rep B156020%
Rep C123327%

Rep B significantly underperforms - investigate and provide coaching.

By Lead Source

SourceWonLostWin Rate
Inbound255033%
Outbound157517%
Referral51033%

Outbound has lower win rate - expected, but useful for forecasting and resource allocation.

By Deal Size

Deal SizeWonLostWin Rate
$0-25K306033%
$25-100K124820%
$100K+32710%

Larger deals have lower win rates - factor this into coverage calculations.

Improving Win Rate

Better Qualification

Pursue opportunities with higher fit. Better qualification may lower pipeline volume but increases win rate and reduces wasted effort.

Sales Methodology

Consistent discovery, value selling, and negotiation processes improve conversion. Invest in training and coaching.

Competitive Intelligence

Understand why you win and lose against competitors. Arm reps with positioning and objection handling.

Deal Coaching

Review in-progress deals to identify risks and improve strategy before opportunities are lost.

Win-Loss Analysis

Conduct structured win-loss interviews with closed deals to understand buyer decision factors.

Win rate is a core sales metric that directly impacts revenue forecasting and sales efficiency. By measuring win rate consistently, segmenting for insights, and systematically improving conversion, sales organizations can achieve predictable growth.

Questions

B2B win rates typically range from 15-30% depending on industry, deal size, and sales motion. Enterprise deals often have lower win rates (15-20%) than SMB deals (30-40%). Compare against your specific industry and deal profile.
