Missed-call cost calculator

Three of your own numbers. One estimate of what unanswered calls may cost you.

Estimated lost revenue

Per month—

Per year—

Missed calls/week × % booked × average value = weekly loss. Monthly = weekly × 4.33. Yearly = weekly × 52.

Estimate only. Some callers leave a message or call back, so treat this as an upper bound.

How to get your numbers

Check your carrier’s call log for one normal week. Count calls you didn’t pick up.

For the booking rate, think about answered calls from new customers. How many became paying jobs?
