Free Sales Pipeline Calculator — Forecast Revenue from Deal Stages
A sales pipeline calculator applies stage-by-stage conversion rates to your active deals to forecast expected closed revenue. Each deal in your pipeline has a probability of closing based on its stage — a qualified lead has a different probability than a proposal sent or contract signed. This tool weights your pipeline accurately.
How to use Sales Pipeline Calculator
Enter deals per stage
Input the number of deals and average deal size at each pipeline stage (Lead, Qualified, Proposal, Negotiation, Closed).
Set conversion rates per stage
Assign a win probability to each stage — or use industry defaults (Lead 10%, Qualified 25%, Proposal 50%, Negotiation 75%).
See weighted pipeline
The calculator shows weighted pipeline value, total potential value, and projected monthly closed revenue.
Frequently asked questions
