From your numbers and three published figures. An estimate, not a promise.

How it works

The math.

Four steps, no hidden figures. Change any assumption below and the estimate follows.

  1. 01Assumption A

    Some people check your site first

    Before they call or write, a share of the people about to get in touch look at your website.

  2. 02Your guess, or B × C

    Some of them leave

    No website or a broken one: your own guess. A slow site: the phone visits that give up on a slow page.

  1. 03Leads ÷ (1 − leak)

    Add back who left

    Your leads are the people who got through. The leads you would have had are your leads ÷ (1 − A × leave share).

  2. 04Leads × close × value

    Turn leads into money

    Lost leads × your close rate × your job value is the revenue lost a month. Times 12 for a year.
