Showroom Visit Value Calculator.
Cost per closed project via the showroom path — the funnel event that actually predicts revenue.
By shakalakaa · 18 Aug 2026
Quick answer: Cost per closed project = cost per visit ÷ (quote rate × close rate). A firm at RM150 per visit, 60% quote rate and 20% close rate pays RM1,250 per closed project — about 1.3% of a RM100,000 project. The showroom visit is the real ID conversion event, not the form fill; most ID form leads never become projects.
FAQ
Why is the showroom visit the real conversion event for interior design?
An ID form fill is a low-commitment signal — quote requests without a site or showroom step rarely close. The showroom visit is where the client sees material samples, meets the team and commits to a scoped conversation. It's the earliest funnel step that narrows to buyers.
How does this differ from a cost-per-lead calculator?
Cost-per-lead measures form fills. This models the full path from visit to closed project — visit to quote, quote to close — and outputs cost per closed project. That figure maps to revenue; cost per lead does not, because most ID leads never become projects.
What inputs should I use?
Your own last-90-days figures — real showroom visits, real quote rate, real close rate on those quotes, real average project value, and real cost per visit across all channels that drove those visits.
