Adjust the sliders to match your market. The defaults reflect our Vroom.DO benchmark — swap in your own numbers once you have real campaign data.
The math behind the numbers
Leads = monthly budget ÷ cost per lead. Bookings = leads × your lead-to-booking conversion rate. That's the whole model — no hidden multipliers.
The $4–6 default comes from the Vroom.DO case: a car rental launch in Punta Cana and Bávaro that went from zero bookings to a steady flow of qualified leads, using search campaigns segmented by city and car type plus conversion tracking on WhatsApp.
Your own cost per lead depends on city, season, and auction competition — treat the default as a starting point, not a promise, and swap in real numbers once a campaign has run.
