Weighted Pipeline Value Calculator — Forecast Revenue from Deal Size & Win Probability
Enter each deal's amount and win probability (%) to instantly calculate your sales pipeline's Weighted Pipeline Value. A free tool for sales managers and RevOps teams.
Tips
- Agree on standard win-probability guidelines per deal stage (e.g. 20% for first meeting, 50% for proposal, 80% for final approval) so estimates stay consistent across reps.
- This tool estimates deals that have not yet closed. Once a deal closes, track it individually with money.business.acv (Annual Contract Value calculator).
- A single large deal with a low win probability can swing the total weighted value significantly, so pay extra attention to accuracy on your biggest deals.
- Win probabilities shift as the quarter progresses, so re-entering them regularly keeps your end-of-quarter forecast more accurate.
Frequently asked questions
Side Note — Why sales forecasts multiply in "probability"
When a sales manager tries to predict how the quarter will land, simply adding up every deal's amount tends to produce an overly optimistic number. Treating a deal that was just proposed the same as one about to be signed means losing a single large, early-stage deal can throw the whole forecast off.
To avoid this, sales organizations widely multiply each deal by its win probability to compute an expected value — the same idea behind expected value in statistics: "if this situation repeated many times, what would the average outcome be," applied in advance to a single deal's forecast.
While money.business.acv handles the annualized value of a single, already-closed contract, this tool sums multiple still-open deals weighted by probability — a different target. Most CRMs build this idea into their pipeline reports by default; this tool lets smaller teams estimate it easily even before adopting a full CRM.
