The formula
Missed-call cost per month = (missed + after-hours calls per month) × (share that are genuine prospects) × (your phone-lead close rate) × (average revenue per closed deal).
A brokerage missing 40 calls a month, where half are real prospects, closing 1 in 10 phone leads on a AED 30,000 average commission, is leaving roughly AED 60,000 a month on the table. Your inputs will differ, that's the point. Use yours.
Why callbacks don't fully recover it
A caller who rings out doesn't wait, they dial the next result on the list. Calling back an hour later competes with a conversation your competitor already had. Recovery beats callback: answer at the moment of intent, book them then and there.
What answering every call costs instead
AI voice minutes are priced in cents, and a receptionist-grade agent runs a few hundred dollars a month at typical volumes. Against the number you just calculated, this is rarely a close decision, the honest question is not the cost, but whether the agent is good enough for YOUR callers. Which is why we let you talk to one before anything else.
