Sales funnels have 3-4 stages typically: visitor → lead → qualified → customer. Compound conversion through multiple stages creates sharp drop-off. This calculator shows stage-by-stage numbers.

10,000 visitors × 25% lead × 30% qualified × 20% close = 150 customers. At 1,000 deal value = 150k revenue. Full funnel conversion 1.5% - typical for B2B.

Identify weakest stage. If top-funnel traffic is strong but closing is poor, spend on sales enablement. Weak top-funnel calls for acquisition channel work. Each stage compounds - 10% improvement in each stage = 33% more customers.

Run it with sensible defaults

Using top funnel visitors of 10,000, stage 1 conversion of 25%, stage 2 conversion of 30%, stage 3 conversion of 20%, the calculation works out to 150,000.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Top Funnel Visitors, Stage 1 Conversion %, Stage 2 Conversion %, Stage 3 Conversion %, and Average Deal Value — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Multiply through stages. Final conversions × deal value = expected revenue. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this as a check-in

Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Example Scenario

10,000 × 25% × 30% × 20% × £1,000 £ = $150,000.00.

Inputs

Top Funnel Visitors:10,000
Stage 1 Conversion %:25
Stage 2 Conversion %:30
Stage 3 Conversion %:20
Average Deal Value:1,000 £
Expected Result$150,000.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Which stage to fix first?
Weakest stage. If 2% conversion from lead-to-customer but 50% visitor-to-lead, fix sales process not traffic. 10% improvement at weakest stage always beats 10% improvement at strongest stage in funnel economics.
