What share of missed calls can you actually win back?

Missed-call text-back vendors love the "60% recovery" claim. Run the actual compounding maths and the honest number is 12-30% of missed calls turned into booked jobs. Here's where that gap comes from and how to measure yours.

The claim you keep seeing

Search "what percentage of missed calls turn into booked jobs" and most results quote a single figure, usually somewhere around 60%. That number almost always comes from one source: text-back software vendors quoting the reply rate to their automated SMS, then treating that as the job conversion rate for every missed call. It isn't. It's one step in a three-step chain, and the whole SERP repeats the same arithmetic error.

The three numbers that actually matter

To go from a missed call to a booked job, three things have to happen, each with its own loss rate:

• You miss the call. Trades typically miss 35-45% of inbound calls. Higher during jobs on site, evenings, and peak season; lower if someone's on the desk full time.
• The caller replies to a text-back. An instant automated text ("Sorry we missed you, what do you need?") gets a 35-50% reply rate. Speed matters more than wording here.
• The reply becomes a booked job. Of the people who reply, 30-60% actually book. Some were price-shopping three other tradespeople, some already called your competitor while waiting, some just wanted a callback time.

The vendor stat quotes the middle step, or sometimes the last one, and implies it applies to the whole missed call. It doesn't. You have to multiply all three.

The compounding formula

Net recovery rate (as a share of all missed calls) is:

Reply rate × Booking rate = Net recovery rate

Note this is applied to calls that were missed and then texted, not to the miss rate itself — the miss rate tells you the size of the pool you're working with, not part of the multiplication. So:

• Low case: 35% reply × 30% booking = 10.5% of missed calls become jobs
• Mid case: 42% reply × 45% booking = 19%
• High case: 50% reply × 60% booking = 30%

That's the honest range: 12-30% of missed calls, net, become booked jobs once you've got a fast text-back running. Not 60%. The 60% figure is the reply rate on its own, dressed up as a conversion rate.

A worked example with real numbers

Say you're a two-van plumbing outfit and you pull last month's call log:

Metric	Figure
Total inbound calls	220
Calls missed (38%)	84
Text-backs sent	84
Replies received (40%)	34
Replies that booked a job (45%)	15

15 booked jobs out of 84 missed calls is a net recovery rate of 17.9% — right in the middle of the honest range, and a long way from 60%. If your average job value is £280, that's still roughly £4,200 a month you weren't collecting before, which is the real pitch. It just isn't 60% of anything.

Run your own figures through the missed call revenue calculator to see what that recovery rate is worth in your business, using your own average job value and call volume.

The five-minute response cliff

Every one of these percentages is sensitive to speed. Response-time studies across various industries (not trade-specific, but the pattern holds in call logs we've seen) show a steep drop-off in the first few minutes after a missed call:

• Under 1 minute: reply rates sit near the top of the 35-50% range
• 1-5 minutes: still reasonable, but noticeably lower
• After 5 minutes: reply rate falls off fast — the caller has often already rung the next number on their list
• After 30 minutes: you're mostly relying on people who couldn't find anyone else

This is why automated instant text-back outperforms a manual "I'll call them back at lunch" approach, even when the human callback is more personal. Speed beats charm in this specific window.

Why the booking-rate step varies so much

The 30-60% booking range depends on things you can partly control and things you can't:

• Job urgency — a burst pipe caller books almost regardless; someone wanting a quote for new guttering next spring is easy to lose
• Price transparency — if your text-back gives a rough callout fee or timeframe, more people commit rather than "just checking around"
• How many other numbers they called — you can't control this, but it's a real chunk of your loss
• Whether a real person follows up the text — a bot reply that never leads to a human confirming details loses bookings at the final step

Measure your own recovery rate, not a vendor's

Vendor case studies are marketing. Your call log is data. Here's how to get your real number over 30 days:

1. Pull total inbound calls and total missed calls from your phone system or CRM for the last 30 days. Calculate your miss rate (missed ÷ total).
2. If you're already running text-back, count how many missed calls got a reply. That's your reply rate.
3. Track how many of those replies turned into a job on the books — a real appointment or quote, not just a "thanks, I'll think about it".
4. Multiply reply rate by booking rate to get your net recovery rate as a share of missed calls.
5. Multiply that by your average job value (check this on the job profitability calculator if you're not sure what a job nets you after materials and labour) to see what it's actually worth.

Do this before you sign up for any text-back tool, and again three months after, so you know whether it's paying for itself rather than trusting a headline percentage from someone selling the software.

The short version

Reply rate and booking rate are real, separate steps, and you multiply them, you don't quote one as if it were the other. Expect 12-30% of missed calls to convert to jobs with a fast, well-run text-back system — call it 20% as a working planning number until you've measured your own. That's still real money most trades are leaving on the table, but it's honest money, not a vendor's rounding error.
