Free tools · Missed-call cost estimator

How much are missed calls costing your business?

Missed calls cost you the customers who would have booked, bought or visited if someone had answered, and that depends entirely on your own numbers. Multiply missed calls per month by the share that are new enquiries, then by your usual conversion rate, and you get the customers at risk; multiply by what one new customer is worth to you for a rupee figure.

There are no built-in benchmarks. We did not find reliable public data on missed-call rates for Indian businesses, so the estimator starts blank. The industry pages below start from clearly labelled example numbers you can replace.

How to use it

  1. Count your calls. From your call history or telephony dashboard, note calls on a normal working day and the share that went unanswered.
  2. Find new enquiries. Check 30 to 50 missed numbers against your contacts to see what share were new enquiries.
  3. Add your conversion rate. From your enquiry register: of the enquiries you answered, what share became customers?
  4. Optionally add a customer value. Enter the average revenue from one new customer, in rupees, from your own accounts. Leave it blank to see customers only.
  5. Read the result. The tool shows missed calls, missed enquiries, customers at risk and, if you entered a value, revenue at risk per month and per year.

Method

  • Missed calls per month = calls per working day × share unanswered × working days per month.
  • Missed new enquiries = missed calls × share of missed callers who are new.
  • Customers at risk = missed new enquiries × your conversion rate.
  • Revenue at risk = customers at risk × your figure for one new customer (only if you enter one).

Limits

  • It assumes missed callers would have converted like answered ones; some call back on their own and some go elsewhere.
  • Count unique missed numbers, not raw missed calls, or repeat attempts will inflate the result.
  • It is revenue, not profit, and says nothing about the cost of answering more calls.

By industry

Each page pre-fills the tool with a labelled example for that industry and answers its own questions.

FAQ

How do I calculate the cost of missed calls?

Missed calls per month × share that are new enquiries × your conversion rate gives customers at risk. Multiply by the average revenue from one new customer for a rupee figure. The estimator above does exactly this.

Do missed calls show up on your bill?

Usually not as missed calls: an itemised bill lists calls that connected. Use your phone’s call history, or your IVR or cloud telephony reports, to count missed calls.

What is a normal missed-call rate?

We have not found reliable public data for Indian businesses, so we do not suggest one. Measure your own over a normal week.

Is my data saved?

No. The calculation runs in your browser and nothing you type is sent to us.
