What could missed calls be costing?
Use your own figures. The result is an estimate, not a promise of recoverable revenue.
Use the figure carefully
Not every missed call is a lost customer, and some callers will try again. The calculator asks you for both the genuine-enquiry share and likely conversion rate so every assumption remains visible.
Choose figures from your own call records
Review a representative period in your provider's call logs. Separate new enquiries from spam, existing-customer calls and repeat attempts by the same caller. A missed ring on one extension may have been answered by someone else, so check the whole call journey before counting it. Use unique unresolved enquiries where possible.
The example inputs are illustrations, not industry benchmarks. Use an observed conversion rate for comparable enquiries and remember that sale value is revenue, not profit. Multiplying one week by 52 assumes the same activity all year; allow for holidays and seasonal changes. All calculations stay in your browser.
BT Business documents call logging by company, site, user and hunt group, but availability and definitions vary by service. Read BT's call-logging documentation. To turn your findings into provider questions, use the VoIP requirements builder.
