How this is worked out
Leads you reach in time visit at your 10% rate. Leads nobody calls never visit. Leads called after an hour visit 2 times less often. Lost visits × your 10% booking rate × your booking value is the value at stake. An estimate to act on, not a forecast.
02/04How it works
Four rules, all of them on the page.
Your own rates do the work. The only outside number is the late-lead factor, and you choose it.
- 01
Leads reached in time
Visit a site at your own visit rate, and book at your own booking rate. These are the numbers you put in.
- 02
Leads nobody calls
Never visit. Every one of them is a visit you could have had at your visit rate.
- 04
What it does not count
Profit, brokerage, or buyers who would have bought anyway. It shows booking value at stake, as a working estimate, not a forecast.

03/04Stop the leak
Seven steps to a call within five minutes.
The full guide explains each one, and what the research behind them does and does not show.
- 01
Bring every lead into one place
Ad forms, WhatsApp, your website and portal emails should land in one list the moment they arrive, not in someone’s inbox.
- 02
Give each lead an owner at once
The moment a lead arrives, one named person is responsible for it. If they are on leave, someone else is.
- 03
Call within five minutes
In working hours, the first call goes out within five minutes. If it is not answered, a short WhatsApp message goes out straight after.
- 04
Try again, on a schedule
A missed call books its own retry: later the same day, and again the next morning. A buyer who misses one call may well answer the next.
- 05
Answer evenings on WhatsApp
A lead that comes in after hours gets a reply on WhatsApp right away and a call first thing the next morning.
- 06
Book the visit on the first call
Offer two time slots for a site visit while you have the buyer on the phone, and send the reminder on WhatsApp.
- 07
Measure it every week
For each salesperson: how long their leads waited for a first call, and how many were never called. What is measured gets faster.

04/04Straight answers
Lead leakage questions builders ask us.
How does the lead leakage calculator work?
Your own rates, applied to the leads that slip.
It takes your monthly leads, how many are never called and how many are first called after an hour, and your own visit rate, booking rate and booking value. Leads reached in time visit at your rate; leads never called do not visit; leads called late visit less often, by a factor you choose. The difference is the visits, bookings and booking value at stake.
Which numbers should I put in?
Last month’s, from your CRM or sheet.
Last month’s: how many leads came in, how many were never called, how many waited more than an hour for the first call, how many leads visited a site and how many visits booked. If you do not track response times yet, that is the first thing to fix; start with an honest guess.
Why is a late lead counted as half as likely to visit?
It is the cautious default; you can change it.
Because it is a cautious assumption. Harvard Business Review reported in 2011 that US firms which tried to reach a lead within an hour were nearly seven times as likely to qualify it as firms that waited longer, but that was not real estate and not site visits. You can switch between ignoring late leads, the cautious two times and the study’s seven times.
Does the calculator save my numbers?
No. It runs in your browser.
No. The arithmetic runs in your browser; nothing you type is sent, stored or used to build a profile. You can copy the result or send it on WhatsApp yourself.
How do I stop the leak?
One list, one owner, a call in five minutes.
Bring every lead into one list as it arrives, give each one an owner at once, call within five minutes in working hours with a WhatsApp message if there is no answer, retry missed calls on a schedule, and measure each salesperson’s time to first call every week. The speed-to-lead guide walks through it step by step.
Not on the list? Ask us the awkward version — we would rather lose a deal on the call than on the third invoice.
