Sales funnel calculator: where are you losing the most deals?

Follow your enquiries through meetings and proposals to deals, and see which stage is worth fixing first.

Your numbers

Results are estimates to guide decisions, not financial advice. Your numbers stay in your browser.

Why the weakest stage matters most

Every stage multiplies the next. So the same 5-point improvement is worth most at the stage with the lowest rate, because it is the largest change relative to where you are.

Deals = enquiries × meeting rate × proposal rate × win rate
Extra deals from +5 points at a stage = deals × 5 ÷ that stage's rate

Typical fixes by stage

  • Enquiry to meeting: faster replies, a clear next step, and qualifying questions on the form.
  • Meeting to proposal: a structured first conversation and a clear way to show value.
  • Proposal to deal: proof, case studies, clear pricing options and timely follow-up.

Questions

What if my funnel has different stages?

Use the closest match. A clinic might use enquiry, consultation, treatment plan and treatment started; a developer might use enquiry, site visit, shortlist and booking.

Where do I get these numbers?

From your CRM, or count the last three months by hand from your enquiry sheet, calendar and proposals.

Why +5 points?

It is a realistic improvement for one stage in a quarter, and using the same step for every stage makes them easy to compare.

Is my data saved?

No. The calculation runs in your browser. Nothing is sent unless you choose to email yourself the result.
