Why Your Sales Forecast is Just a Guess (And How to Fix It)

Pipeline × win rate = forecast. This formula sounds scientific but produces wildly inaccurate results. Here's a better approach to B2B sales forecasting.

"What's your Q3 forecast?" The sales head looks at the pipeline: ₹18 crore in open deals. Applies a rough 35% close rate: "₹6.3 crore." This is not a forecast. It's ₹18Cr × 35% = ₹6.3Cr, with complete disregard for deal quality, stage, age, and probability. And it will be wrong by 40%.

Stage-Weighted Forecasting: Step by Step

Instead of one blanket win rate, assign a probability to each pipeline stage based on historical data:

  • New Contact: 5% — too early to commit
  • Sample/Evaluation: 20%
  • RFQ Received: 45%
  • Quoted: 55%
  • Verbal confirmation: 80%
  • PO Expected this week: 92%

Apply these probabilities to every deal. Sum the weighted values. That's your real forecast — not a gut-feel percentage applied to a total number.

The Three-Bucket Forecast

📊

Pipeline

All active deals, stage-weighted. This is your realistic base forecast — what you should plan your business around.

Best case

Quoted and above deals. If everything goes well, this is the upside scenario for the quarter.

Committed

Verbal confirmation and PO expected deals only. This is what you can almost guarantee. Use for production planning.
