Sales Forecast Calculator

Forecast the open pipeline you already have. Add opportunities, stages, win probabilities, and close dates to model a selected period.

Forecast existing opportunities

Use one row per open opportunity and a consistent currency: USD. Select inclusive start and end dates. Closed-won revenue is not part of this open-pipeline model. Sample rows demonstrate the calculation; replace them with your own values.

How weighted forecasting works

Weighted forecast = sum of deal value × win probability for opportunities closing inside the selected dates. Stage totals show concentration; stage names alone do not set probabilities. Calibrate each probability with historical results. Out-of-period opportunities are counted separately, not silently included.

Not the same as pipeline planning

The Pipeline Calculator works backwards from a target. This forecast works forwards from actual open opportunities. It does not model slippage, correlated losses, or cash collection. Use a deal scorecard to challenge weak evidence before raising a probability.
