Sales Funnel Revenue Calculator

Estimate customers, revenue, gross profit, weighted pipeline value, and the most sensitive stage in a sales funnel.

Inputs

Defaults are visible and can be changed before calculation.

Inline validation messages appear here when a value needs to be corrected.

Results

Results are deterministic scenario outputs, not guarantees.

Enter values and calculate to see the summary, supporting metrics, warnings, and interpretation.

Interpretation

Deterministic interpretation rules will explain what the modeled result means once a calculation is available.

Detailed breakdown

Intermediate calculation rows will appear here after calculation.

Formula

Rate-mode stage count

nextStageCount = previousStageCount × stageConversionRate

Expected revenue

expectedRevenue = expectedCustomers × modeledDealValue

Gross profit

expectedGrossProfit = expectedRevenue × grossMarginRate

Weighted pipeline value

sum(stageCount × modeledDealValue × closeProbabilityByStage)

Required top-of-funnel volume

targetRevenue / modeledDealValue / endToEndConversionRate

Assumptions

Count mode uses the entered stage counts and derives conversion rates from adjacent stages.
Rate mode starts with the entered top-of-funnel volume and applies each stage conversion rate in sequence.
Weighted pipeline value uses deterministic close probabilities, not a forecast or guarantee.
The sensitivity stage is the stage where the selected relative conversion-rate lift creates the largest modeled revenue gain.

Worked example

Example: visitors to customers

With 10,000 visitors, 500 leads, 200 qualified leads, 80 meetings, 40 proposals, and 12 customers at a 5,000 average deal value, expected revenue is 60,000 and end-to-end conversion is 0.12%.

FAQ

Should I use count mode or rate mode?

Use count mode when you already have stage counts from a real funnel. Use rate mode when planning from a starting volume and assumed conversion rates.

Is weighted pipeline value a forecast?

No. It is a deterministic scenario value created from the counts, average deal value, and close probabilities entered in the form.

How is the sensitivity stage selected?

Each stage conversion rate is lifted by the configured sensitivity percentage, capped at 100%, and the stage with the largest modeled revenue gain is shown.
