Missed call cost calculator: what are you losing?

Estimated missed-call cost = calls received × share unanswered × share of prospects × conversion rate × average deal value. Illustrative example: 20 calls a day, 25% unanswered and a €450 average deal give about €3,800 in potential lost monthly revenue under the assumptions below. Replace those assumptions with your own figures.

Potential revenue lost

€3,780 per month

€45,360 per year

Under your assumptions: 105 missed calls a month, about 8.4 potential lost clients.

Monthly loss vs what VocalReception costs to answer all those calls

Revenue lost €3,780

VocalReception €294.00

€79/month with 400 min included, then €0.25 per additional started minute. Estimate for all calls, with no cap, excluding SMS, setup and VAT.

Estimated potential loss is about 13 times VocalReception’s monthly cost. This ratio does not guarantee recovered revenue.

How it is calculated

The calculation estimates potential loss from your assumptions and only counts new clients. Some callers call back: this is neither a measured result nor a guarantee of recovered revenue.

Formula

Calls per month = calls per day × working days
Missed calls = calls per month × % unanswered
Lost clients = missed calls × % prospects × % conversion
Revenue lost per month = lost clients × average deal value; per year = × 12
VocalReception cost = €79 + max(0, calls per month × call length rounded up to a whole minute − 400) × €0.25 (no cap or SMS; excluding €199 setup)

Assumptions

Default deal values: real estate €3,000 (order of magnitude of agency fees per signed mandate), trades €450, practice €180, restaurant €60. Replace them with your own.
The default unanswered rate is an illustrative example, not an industry average. Use your carrier’s call log.
A missed prospect call is assumed lost. Some callers do call back; lower the conversion rate if your clients are loyal or captive.
The entered call length is rounded up to a whole minute for each call. Actual call lengths may vary.
Amounts exclude VAT.

Frequently asked questions

How much does a missed call cost a business?

A missed call costs the probability that it was a prospect × your close rate × your average deal value. With 40% prospects, a 20% close rate and a €450 deal, each missed call is worth about €36 in lost revenue on average.

What is a normal missed call rate?

There is no universal rate for your business. Measure yours from your carrier’s call log over one month. The calculator’s default is illustrative.

Do callers leave a voicemail?

Some leave a message, others call back or contact another business. Measure messages and callbacks before estimating your losses.
