Weighted Pipeline (Sales Forecast) Calculator

Weighted forecast = Σ (pipeline value in each stage × that stage's win probability). It turns a raw pipeline into the revenue you can expect.

Weighted forecast

$300,000

Total raw pipeline

$900,000

Weighted forecast = (discovery stage value × discovery win probability ÷ 100+proposal stage value × proposal win probability ÷ 100+negotiation stage value × negotiation win probability ÷ 100) = $300,000
Total raw pipeline = discovery stage value+proposal stage value+negotiation stage value = $900,000

Frequently asked questions

How do you calculate a weighted pipeline?
Multiply the value in each stage by the probability of winning from that stage, then add the results. $400k × 10% + $300k × 40% + $200k × 70% is a $300,000 forecast.
Where do stage probabilities come from?
From your own history: of all deals that reached Proposal in the last year, what share were won? Default CRM percentages are rarely right for your team.
Is a weighted pipeline accurate?
It works well across many deals and badly on a few large ones. With a small pipeline, review the biggest deals one by one instead.
