TL;DR
In our illustration, a 3-technician AC service business that misses 7 or 8 of its 30 daily calls in peak summer loses about ₹56,000 of jobs a month, or ₹1.68 lakh from April to June. Each missed call a day is worth about ₹7,500 a month in this model, so a fix costing up to ₹2,400 a month pays for itself by winning back two ₹1,200 jobs.
In our worked example, an AC service business with three technicians that misses 7 or 8 of its 30 calls a day in peak summer loses about ₹56,000 of jobs a month. If that rate holds across April, May and June, the season's loss is about ₹1.68 lakh, all from calls nobody picked up.
Every input below is an assumption, and every result is our calculation, because no reliable Indian study measures missed calls for service businesses. Swap in your own figures from a week of call logs and the same method gives you your real cost.
The formula
Revenue lost a month = missed calls a day × share that are new job enquiries × share of those who would have booked × average job value × working days a month.
Each part needs its own number:
- Missed calls a day: count them from your phone's call log, not from memory.
- Share that are new job enquiries: some missed calls are spam, suppliers or existing customers, and only new enquiries are lost sales.
- Share who would have booked: not every enquiry becomes a job, even when you answer.
- Average job value: the average invoice across gas refills, installations and repairs, not just service visits.
A worked example: three technicians in May
This is an illustration. The assumptions are:
- 30 calls a day in peak season, and 26 working days a month.
- 25% of calls go unanswered because all three technicians are on jobs.
- 60% of missed calls are new job enquiries.
- 40% of those callers would have booked if someone had answered.
- An average job value of ₹1,200.
- The May rate holds for all three peak months, April to June.
Our calculation, step by step:
- 30 calls × 25% missed = 7.5 missed calls a day.
- 7.5 × 60% new enquiries = 4.5 new-customer calls missed a day.
- 4.5 × 40% who would have booked = 1.8 jobs lost a day.
- 1.8 jobs × ₹1,200 = ₹2,160 lost a day.
- ₹2,160 × 26 working days = ₹56,160 lost a month.
- ₹56,160 × 3 months, April to June = ₹1,68,480 lost in the season.
Why ₹1,200 as the average job? Urban Company's Bangalore AC page lists foam-jet servicing from ₹649, a gas refill with check-up at ₹2,800 and installation from ₹1,299 (Urban Company, checked 24 September 2026). A summer mix of cleaning, gas and installation jobs lands between those figures, but the average of your own last 20 invoices is a better number.
Revenue is not profit. If parts, gas, fuel and wages take half of each job (another assumption), the margin lost in this example is about ₹28,000 a month.
How the loss changes with your miss rate
With the other assumptions held steady, each missed call a day, every day for a month, is worth ₹7,488 (60% × 40% × ₹1,200 × 26 days). The table scales that up; every figure in it is our calculation.
| Missed calls a day | Jobs lost a day | Revenue lost a month |
|---|---|---|
| 3 | 0.72 | ₹22,464 |
| 5 | 1.2 | ₹37,440 |
| 8 | 1.92 | ₹59,904 |
| 12 | 2.88 | ₹89,856 |
The same three people can sit in the top row in March and the bottom row in May, because missed calls rise in the weeks when all three are out on jobs.
Measure your own numbers in one week
You need seven days of data and about 20 minutes an evening.
- Each evening, open your phone's call log and count the day's incoming calls and missed calls. With a shared business number, a call-analytics dashboard shows missed calls and answer rate directly.
- Call back every missed number the same day and note one word: new, existing, spam or supplier.
- For the new ones, note whether they booked, had already booked someone else, or only wanted a price.
- Take the average of your last 20 invoices as your job value.
- Put the week's figures into the worksheet.
Your worksheet
- Missed calls a day: [ ]
- × share that were new enquiries: [ ] %
- × share of those who book when you answer: [ ] %
- × average job value: ₹ [ ]
- × working days a month: [ ]
- = revenue lost a month: ₹ [ ]
Step 3 has a useful side effect. The callers who "already booked someone else" tell you how fast your market expects a callback.
What a fix has to recover to pay for itself
No fix wins back every missed job. The useful question is how many jobs a month a fix must save to cover its own cost.
| Fix | Monthly cost with 18% GST | Jobs to break even at ₹1,200 |
|---|---|---|
| Auto-reply app plus call forwarding | ₹0 to install | 0 |
| Superfone AI Receptionist | ₹1,770 (₹9,000 per 6 months) | 2 |
| Exotel Dabbler, which lists missed call services | ₹2,360 (₹9,999 per 5 months) | 2 |
How we compared: prices from each provider's official page (Superfone, Exotel), checked in September 2026. The monthly figures are our calculation: each plan's price divided by its months, plus 18% GST, the rate on telecom services (CBIC). The first row uses free-to-install Android apps and Jio's free forwarding service (Jio).
In the worked example, 1.8 jobs are lost a day, or 46.8 a month. If a fix wins back one in ten of them (our assumption), that is about 4.7 jobs, or ₹5,600 of revenue a month, more than twice the cost of any row above.
What the formula leaves out
The table counts only this summer's job. A customer you serve in May is the one you want calling again before next summer, or recommending you in the building's WhatsApp group, and a missed call loses that too.
Urgency is the other gap. A caller whose AC has stopped in peak heat is unlikely to wait long for a callback, so the speed of your response matters as much as whether you respond at all.
Where TalkEasy fits
TalkEasy by GrowEasy is one business number for your whole team, running in an Android app alongside each person's SIM. With missed-call automation on, it calls back customers whose calls were missed, 24x7, following your routing and availability rules (TalkEasy). Its call analytics show missed calls, answer rate and peak calling hours, which is the week-one data this page asks you to collect (call analytics).
TalkEasy Pro costs ₹999 a month plus GST, ₹1,178.82 with GST, for unlimited users and 3 hours of talktime a day; the pricing page lists what each plan includes. If your own numbers come out small, say two or three missed calls a week, skip it: an auto-reply app is enough, and our guide to five no-code ways to handle missed calls shows how to set one up.
