the Leak Calculator

Four numbers. One figure. About ninety seconds.

This is the same arithmetic we run in The Revenue Review, with four inputs instead of your books. It is not a quote and it is not a diagnosis — it tells you whether the number is big enough to be worth two weeks of your attention.

Your number. Nothing here is pre-filled from anyone else.

%

We start at 30% because that is the low end of the range in our own audit notes. It is an assumption, not a finding — put in your own figure and the result follows.

We start at 25% because that is the low end of the 20–40% range in our own audit notes. It is an assumption, not a finding.

What happens next

Send us your four numbers and we will tell you if they are worth chasing.

A 20-minute call, your figures, no deck. If the honest answer is that your leak is too small to be worth $4,500, we say that on the call — and you keep the number either way.

Your four calculator inputs and your figure are sent with this — so the call starts from your number, not from zero.

We use this to call you back about your inquiry. We do not sell or share it, and one line asking us to stop is enough.

We call web forms back the same business day. Or skip the form — +1 (202) 600-6027.

What this number is, and what it is not

It is a ballpark, not a finding.

  • It uses your four numbers and two of ours. The follow-up share and the close rate start at values we chose and labeled. Change them and the figure changes — that is the point of leaving them editable.

  • It counts one leak, not all of them. Inquiries that die after first contact. It does not count customers who left, quotes lost on price, or work you under-charged for.

  • Not all of it is recoverable. Nobody recovers a leak in full. The Revenue Review exists to tell you which part of it is reachable, what it costs to reach, and whether that is worth doing.

This is the same rule every figure on this site follows: it is your input, a cited source, something we measured on ourselves, or a labeled assumption. There is no fifth kind.
