How Hold Times Destroy Small Business Revenue
When customers call your business and hear hold music, the clock starts ticking — and not in your favor. Research shows that 60% of callers hang up after just one minute on hold, and 34% of those who abandon never call back. For a small business, every abandoned call is a lost appointment, a lost sale, or a lost client relationship that may never be recovered.
Understanding the Erlang-C Model
This calculator uses a simplified version of the Erlang-C queuing model, the same math used by professional call centers to staff their phone lines. It considers your call volume, the number of people answering phones, and average call duration to predict how long callers wait on hold. From there, we estimate how many callers abandon based on published research on caller patience thresholds.
Why Small Businesses Are Hit Hardest
- • Limited staff: With 1–3 people answering phones, even a small spike in call volume creates hold times
- • Multi-tasking: Your receptionist is also checking in clients, processing payments, and handling walk-ins
- • Peak-hour surges: Monday mornings and lunch hours create call bottlenecks that are impossible to staff for
- • No visibility: Most small businesses have no idea how long their callers actually wait
- • Customers overestimate: Studies show callers perceive hold times as 36% longer than they actually are
Zero hold times. Zero abandoned calls.
ReadyToTalk's AI receptionist answers every call on the first ring — so your customers never wait and you never lose revenue to hold times.

How long will customers wait on hold before hanging up?+
Research consistently shows that 60% of callers hang up after just 1 minute on hold. After 2 minutes, abandonment rates climb above 80%. The average caller’s patience threshold is approximately 90 seconds, but customers perceive hold times as 36% longer than they actually are — so even 40 seconds of hold time feels like nearly a minute.
What percentage of callers who hang up never call back?+
Studies show that 34% of callers who abandon a call never call back. They either find another provider, solve the problem themselves, or simply give up. For competitive industries like legal services or home repair, that caller is likely contacting your competitor within minutes.
How does the Erlang-C model work?+
Erlang-C is a mathematical formula used by telecom engineers and call centers to predict wait times based on call volume, number of agents, and average call duration. It calculates the probability that a caller will need to wait and the expected average wait time. This calculator uses a simplified version appropriate for small business phone volumes.
How is the abandonment rate calculated?+
We use an exponential decay model based on published research on caller patience. The model assumes an average patience threshold of 1.5 minutes — meaning about 50% of callers will hang up if they wait that long. The actual abandonment rate depends on your specific hold times, which are calculated using the Erlang-C formula based on your inputs.
What is an AI receptionist and how does it eliminate hold times?+
An AI receptionist like ReadyToTalk answers every call instantly — there is no queue because the AI can handle unlimited simultaneous calls. It greets callers, answers questions, schedules appointments, and routes calls to the right person. Since every call is answered on the first ring, hold time drops to zero and abandonment rates virtually disappear.
