Cost per lead lies: a 20-line calculator for real estate cost per qualified lead and cost per booking

Real estate marketing in India is typically measured by cost per lead. However, this metric can be misleading because a lead that never responds costs the same as a lead that books a site visit. To provide a more meaningful measurement, a calculator has been created that converts sales team inputs into two key metrics: cost per qualified lead (CPQL) and media cost per booking. This post explains how the calculator works and provides an example of its use.

The calculator requires five inputs: monthly media spend, number of leads, qualification rate, qualified leads per booking, and earning per booking. Using these inputs, the calculator generates three outputs: cost per lead, cost per qualified lead, and media cost per booking. It also calculates the number of bookings generated from the spend and the percentage of media spend relative to the earnings generated by each booking.

The calculator is designed to run entirely in the browser, making it commercially sensitive as it does not send any data anywhere. This allows developers and sales teams to share the tool without concerns about data privacy. The output is formatted to display Indian currency formatting and handles divide-by-zero situations gracefully.

The calculator provides insights that can help determine if the media spend is too high relative to the earnings generated by bookings. If media costs more than half of the earnings from a booking, the recommendation is to focus on improving qualification and reducing the time to lead, rather than increasing the media spend. The full methodology is outlined in QDnCo's guides on cost per qualified lead for developers and lead cost for brokers.
