What is Stage Probability?
Stage probability translates a stage into odds. It is the number that makes weighted pipeline and stage forecasting possible.
The common mistake is setting these probabilities by intuition. Grounded in real conversion history, they sharpen the forecast; guessed, they quietly distort it.
Short answer
Stage probability is the default win likelihood assigned to each pipeline stage, ideally derived from the historical share of deals in that stage that closed won. A Proposal stage might carry 50 percent. Stage probabilities are the multipliers in weighted pipeline and the backbone of stage forecasting, so calibrating them from real conversion data, not gut feel, is essential to an accurate forecast.
Key takeaways
- Default win likelihood per pipeline stage.
- Derived from historical stage-to-close conversion.
- The multiplier in weighted pipeline.
- Must be calibrated from real data.
Why it matters
Every weighted forecast rests on stage probabilities. If they reflect real conversion, the forecast is trustworthy; if they are optimistic guesses, the whole weighted number is quietly wrong.
How Ardovo handles it
Ardovo sets stage probabilities from your actual stage-to-close conversion and Rook refines them per deal with real signals, so the weighting reflects both the stage and the specific deal.
Frequently asked questions
What is stage probability?
It is the default win likelihood assigned to each pipeline stage, ideally derived from the historical share of deals in that stage that closed won. It is the multiplier used in weighted pipeline and stage forecasting.
Where should stage probabilities come from?
From your real stage-to-close conversion history, not intuition. The share of deals reaching each stage that eventually closed won gives you calibrated probabilities. Guessed probabilities produce a weighted forecast you cannot trust.
Can stage probability be overridden per deal?
Yes, and it should be when real signals differ from the stage default, such as a stalled late-stage deal that deserves a lower probability. The best forecasts start from stage probability and refine it with deal-level evidence.
