How to calculate the cost of sales call no-shows
The cost of no-shows is the calls you lost, times your close rate, times your deal value.
- Held calls = booked calls × show rate
- No-shows = booked calls minus held calls
- Lost deals = no-shows × close rate
- Lost revenue = lost deals × deal value
You already paid for every one of those calls. The ad ran. The lead came in. The slot got booked. Then nobody showed up.
Worked example (illustrative, using the sample numbers above):
| Step | Math | Result |
|---|---|---|
| Held calls | 80 × 65% | 52 |
| No-shows | 80 minus 52 | 28 |
| Lost deals | 28 × 20% | 5.6 |
| Lost revenue per month | 5.6 × $5,000 | $28,000 |
| Lost revenue per year | $28,000 × 12 | $336,000 |
| Gain from a 10 point lift | 80 × 10% × 20% × $5,000 × 12 | $96,000 a year |
$96,000 a year. No new ads. No new leads. Just more people turning up to calls you already booked.
How to read your no-show cost
Lost revenue is the ceiling of what the leak costs, because it assumes every no-show would have closed at your normal rate.
Some would not have. People who ghost are often less keen. So treat the monthly loss as the size of the hole, and the lift gain as the realistic prize.
The lift line is the one to act on. Ten points of show rate is a goal you can put on a whiteboard. It also lowers your cost per held call on the SAME spend, which you can check in the cost per lead calculator.
Sales call no-show rate benchmarks
Across B2B booking channels, about one in four booked sales meetings never happens, per Focus Digital's 2026 no-show report, which puts the blended no-show rate at 25%.
- One-click instant booking at form fill: 8% no-show, per Focus Digital.
- Paid search or paid social lead form: 33% no-show, per Focus Digital.
- Outsourced appointment-setting agency: 42% no-show, per Focus Digital.
RevenueHero's December 2024 benchmark counted 419 no-shows across 6,428 scheduled meetings, a 6.5% rate, with industries ranging from 0% in healthcare to 18.1% in education software.
Wide spread. The pattern is clear though: the faster someone books after raising their hand, the more likely they show. More on that in sales call show rate benchmarks.

How to cut no-shows
You cut no-shows by booking people while they are still interested, then reminding them like you mean it.
- Put the calendar inside the funnel. Our 7-question quiz funnel takes about 30 seconds and ends on the calendar, not a "we'll be in touch" page.
- Follow up by email and SMS. Reminders do the heavy lifting between booking and the call.
- Report held calls, not booked calls. Any agency reporting booked calls alone is hiding this exact leak.

Questions
How do you calculate the cost of a no-show?
Multiply no-shows by your close rate and your deal value. 28 no-shows a month at a 20% close rate and a $5,000 deal value is 5.6 lost deals, or about $28,000 in lost revenue a month.
How do I calculate show rate?
Show rate = held calls / booked calls × 100. If 52 of 80 booked calls happen, your show rate is 65% and your no-show rate is 35%.
What is a normal no-show rate for B2B sales calls?
Focus Digital's 2026 report puts the blended B2B no-show rate at 25%, ranging from 8% for one-click instant booking at form fill to 42% for outsourced appointment-setting agencies. Your own booking channel matters more than the average.
How much is a 10 point lift in show rate worth?
Multiply booked calls by 10%, then by close rate and deal value. With 80 booked calls, a 20% close rate and a $5,000 deal, 10 points is 8 extra held calls and about $8,000 a month, or $96,000 a year.
Is the lost revenue figure exact?
No. It assumes no-shows would have closed at your normal close rate, and some would not. Treat it as the ceiling of the leak and the lift gain as the realistic target.
How do I reduce sales call no-shows?
Book the call in the same session the lead raises their hand, send email and SMS reminders, and report held calls instead of booked calls. The show-up playbook covers the full sequence.
