Missed call cost calculator

Use this missed call cost calculator with monthly calls, missed share, conversion and order value. Enter a recovered share to compare before and after.

Free, no sign-up. Runs in your browser, with no AI calls.

Multiply monthly eligible calls by the missed share, sales conversion and average first order value to estimate revenue at risk. Multiply by twelve for an annual scenario. Enter a recovered share to see potential recovered revenue and remaining risk. No conversion or recovery rate is assumed by the calculator.

Your figures

Enter your own amounts and shares. Results update as you type. No income, salary or call assumptions are prefilled.

Currency changes the units shown. No exchange-rate conversion is applied.

Count unique eligible sales calls that do not return through another channel. Exclude spam, duplicate attempts and support calls. Revenue at risk is an opportunity estimate, not profit or guaranteed lost sales.

How to use this tool

Count eligible calls
Enter unique incoming sales calls per month and the percentage missed. Exclude spam, duplicate attempts, support calls and callers who later return through another channel. Missed eligible calls = monthly calls times missed share / 100.
Estimate first order revenue
Expected orders = missed eligible calls times conversion / 100. Revenue at risk = expected orders times average first order value. This assumes missed callers would convert like the eligible calls you measured. It counts the first order only and does not calculate profit.
Enter your recovery scenario
Potential recovered revenue = revenue at risk times recovered share / 100. Remaining risk = before risk minus potential recovery. The same conversion and order value apply before and after. Recovery stays unavailable until you enter a share, including an explicit zero.

Questions before you start

No. Conversion accounts for calls that would not become an order. Exclude callers who retry or order elsewhere from your eligible missed-call estimate. The output is an opportunity scenario based on your inputs, rather than measured losses.

No. You choose the recovered share. The calculation assumes those calls have the same sales conversion and first order value as your baseline. Actual recovery depends on caller intent, response quality and your ability to deliver.

A percentage applied to calls produces an expected count, which can be fractional. The calculator keeps the unrounded count when multiplying by order value. The annual figure repeats the monthly scenario twelve times and assumes no seasonal change.
