How many leads you need to sell out a development

Enter how many units you want to sell and how your funnel behaves. The tool works backwards: how many leads, viewings and reservations you need, what that costs in ads and how many months it takes.

Your numbers

Editable example assumptions, not a market average.

Empty on purpose: there is no sourced off-plan figure. Enter yours.

To sell 40 units you need 6,536 leads: about 163 per unit. Enter your cost per lead to see the budget and the months. Your lowest rate is «reservation». Raising it cuts the leads you need the most.

Steady state: leaves out a campaign's learning months and the time between first contact and reservation. Ad spend only, no agency fee.

How to use it

  1. Units to sell. The ones this campaign has to close, not the whole development if part of it is already sold.
  2. The four funnel rates. Out of 100 leads, how many you reach; out of 100 reached, how many book a viewing; out of 100 viewings, how many reserve; and out of 100 reservations, how many go on to sign the sales agreement.
  3. Your cost per lead. What you pay in ads for each person who leaves their details. Take it from your last campaigns: ad spend divided by leads.
  4. Monthly ad spend. With it the tool tells you how many months it takes to bring in all those leads.

The rates that come pre-filled are example assumptions. They are not a market average. Replace them with yours as soon as you have a month of data.

How it's calculated

It starts at the end of the funnel and works up, dividing by each rate:

  1. Reservations = units ÷ % of reservations that sign
  2. Viewings = reservations ÷ % reservation rate
  3. Reached = viewings ÷ % viewing rate
  4. Leads = reached ÷ % contact rate
  5. Ad budget = leads × cost per lead
  6. Months = ad budget ÷ monthly ad spend

Every result is rounded up: there is no such thing as half a viewing or half a lead. The budget uses the rounded-up leads.

It is a steady-state calculation. It leaves out the first months while a campaign is still learning, and the time between first contact and reservation, which off-plan can be weeks or months. It also leaves out the agency fee: ad spend only.

What to do with the result

If the lead count looks impossible, don't start with the budget. Look for the lowest rate.

Raising the contact rate from 50 to 70 out of 100 cuts the leads you need by almost 30 %, without spending a dirham more on ads. It is usually the cheapest lever: it depends on replying fast and calling on time. The landing page matters too, because it can filter before the form: this is how we build a landing page per project. And if you want the ads, the landing page and the follow-up run for you as one system, see lead generation in Dubai.

Frequently asked questions

It depends on your funnel; there is no single figure. With this page's example assumptions (60 % contact, 15 % viewing, 8 % reservation and 85 % signing) it comes to about 163 leads per unit. With your real rates the number changes a lot, which is why every rate is editable.

Because we won't put in a figure without a source. The off-plan cost-per-lead numbers that circulate in the UAE don't say where they come from. Enter your own: ad spend divided by the leads it brought in. Without it, the tool still counts leads, viewings and reservations, but not the budget.

It depends on the project, the buyer's payment plan and the time until the sales agreement is signed. The 85 % on this page is an example assumption, not market data. If you don't track it yet, count how many reservations from your last launches fell through before signing.

No. The budget is ad spend only, paid directly to Meta from your own ad account. Our published fees are on top: from AED 4,100 a month (≈ €1,000) plus an AED 2,000 set-up (≈ €500). The tool leaves them out because it counts what the funnel needs, not what an agency charges.

No. Everything is calculated in your browser and sent nowhere. If you want us to review them, book the Captación X-Ray and we go through them together on the call, with your real data. When you close the page, nothing stays on our side.
