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.

Everything you need in one Sales Pipeline Calculator
Weighted pipeline value
Multiplies each stage's deal value by its win probability for a realistic forecast — not the optimistic total that assumes every deal closes.
Stage-by-stage breakdown
Each pipeline stage shows its own weighted contribution, so you see exactly which stages are carrying the forecast and which are dragging it down.
Pipeline coverage ratio
Compares total pipeline against your quota and flags whether you have the 3–4× coverage most teams need to comfortably hit target.
Fully editable stages
Rename stages, change probabilities, and add or remove rows so the model matches your actual sales process.
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.
Typical pipeline stage win probabilities
| Stage | Typical win probability | Meaning |
|---|---|---|
| Lead | ~10% | New contact, not yet qualified |
| Qualified | ~25% | Fit and budget confirmed |
| Proposal | ~50% | Proposal or quote sent |
| Negotiation | ~75% | Terms being finalized |
| Closed-won | 100% | Deal signed |

Negotiation win% = 100%Negotiation-stage deals still slip — use 70–80% until the contract is countersigned. Only Closed-won deserves 100%.
avgSize = $5,000 for Lead, Qualified, Proposal, NegotiationDeal size often grows as deals advance — upsells and expanded scope push Negotiation values higher. Segment by stage for an accurate forecast.
All open CRM deals included regardless of last activityRemove deals with no activity in 30+ days. Stale deals inflate pipeline coverage and make the forecast misleading.
Expected close = weighted pipeline value exactlyWeighted pipeline is a probability-adjusted estimate, not a guarantee. Actual close rates vary ±25–35% from projected — use it as a range, not a hard number.
total pipeline = 1.5× quotaMost teams need 3–4× pipeline to hit quota because 70–75% of pipeline won't close in the period. If you're below 3×, add deals or extend the period — quota is at risk.
Q1 and Q2 deals in the same pipeline viewInclude only deals expected to close in the current reporting period. Cross-period mixing inflates coverage and distorts the weighted forecast.
Frequently asked questions
A sales pipeline is a visual representation of deals at each stage of the sales process — from initial contact to closed-won. It helps sales managers forecast revenue and identify where deals are stalling.
