Forecast accuracy

Quick answer

How close the forecast committed at period start lands to actual results.

Key takeaways

  • A wrong forecast means wrong stock, wrong cash flow, wrong hiring
  • A director who does not know their own variance cannot commit to the board

Accuracy = 1 - |forecast - actual| / actual, measured per cycle and per owner.

Why it is a management issue

  • A wrong forecast means wrong stock, wrong cash flow, wrong hiring
  • A director who does not know their own variance cannot commit to the board

How to improve it

  • Probability driven by stage and real activity, not rep optimism
  • Weekly review only on deals that move the number
  • Per-rep history: consistent over-callers get weighted

Real-world example

€900k forecast against €700k actual is 71% accuracy. If 80% of the gap comes from two reps, the fix is targeted.
