## Missed-call SMS contribution calculator: how is the result calculated?

An SMS follow-up scenario needs eligible calls and a reply rate before it estimates customers. The reply rate describes people who respond to the message; the close rate describes how many of those replies become customers.

## How the calculation works

An SMS follow-up scenario needs eligible calls and a reply rate before it estimates customers. The reply rate describes people who respond to the message; the close rate describes how many of those replies become customers. Apply revenue and margin, then subtract the monthly messaging and support cost.

Do not enter all missed calls if some numbers cannot receive texts or some events are excluded by the workflow. A sent message and a customer reply are different stages. The output is monthly net contribution under the entered assumptions, not return on a setup investment.

Include any one-time setup cost in a separate project comparison. Later evidence should identify provider acceptance, replies and customer outcomes individually, with duplicate inquiries removed consistently.
