How Long Will a Customer Wait Before Calling Your Competitor?

When a customer calls your business and doesn't get an answer, a clock starts. How long that clock runs before they dial a competitor varies by situation, urgency, and the caller — but the research on call abandonment and voicemail behaviour points consistently in one direction: the window is shorter than most business owners assume, and it gets shorter the more urgent the caller's need.

Most of the available research on this topic comes from the United States. Canadian-specific studies on call abandonment and consumer patience at the small business level are limited, and we'll note where data is drawn from US sources. The general behavioural patterns, however, appear consistent across North American markets.

How Fast Callers Abandon a Call on Hold

For callers who reach a business and are put on hold, patience is measured in seconds rather than minutes. According to Nextiva's Customer Patience Data Study — a report by Nextiva, a US-based VoIP provider — 54% of callers hang up after being on hold for up to eight minutes. Research compiled by Brightmetrics in their 2025 call centre analysis found that over 60% of callers abandon a call within the first two minutes of waiting.

The pattern that emerges across multiple data sources: call abandonment climbs sharply in the first minute or two and then plateaus. Most callers who will abandon have already done so by the time you reach the five-minute mark. After that, you're left with the minority who are either very patient or have no immediate alternative.

This data applies most directly to callers who are connected but waiting — a hold queue, a business with a long ring time, or a call centre environment. For callers who simply ring and get no answer, the dynamic is different and faster.

The Voicemail Decision Happens in Seconds

When a call goes to voicemail, the decision to leave a message or hang up happens almost immediately. Multiple research sources in the telephony industry — including reports from answering service providers who analyze their own call data — consistently report that a large majority of callers do not leave a voicemail when they reach one. Estimates across these sources range from roughly 67% to 80% of callers hanging up without leaving a message, depending on the industry and context.

It's worth being clear about the nature of this data: the most precise figures come from vendors with a commercial interest in demonstrating that voicemail fails callers, so they should be read with that context in mind. What is more reliably established is the direction: most first-time callers to a small business who reach voicemail do not leave a message, and many will not attempt to call back.

The reasons are intuitive. A caller reaching voicemail has no certainty the message will be heard, no estimate of when a callback will happen, and no way to convey urgency. For callers with an immediate need — finding a plumber on a weekend, booking an appointment before the week fills up — waiting is not a viable option.

What Happens After a Missed Call

A 2024 study by 411 Locals, a US-based digital marketing company, analyzed inbound call data from 85 businesses across 58 industries. The study found that only 37.8% of inbound calls were answered by a live person — meaning 62.2% went unanswered in some form. This is a vendor-produced study from a company with a product to sell, and the sample of 85 businesses is small enough to limit generalizability. Nevertheless, it represents one of the few analyses of actual call answer rates at small businesses, and the direction of the finding — that a majority of calls go unanswered — is consistent with the broader literature on the topic.

What happens after those unanswered calls? Research by Vendasta — a Canadian-founded software company — found that 78% of customers make a purchase from the first business that responds to their inquiry. This is a speed-to-lead finding: across industries, the first responder wins the sale at a disproportionate rate. The implication for a business that consistently misses calls is that even when the caller does try again, they may already have been served by whoever answered first.

Urgency Determines the Timeline

The data above describes average behaviour across a wide range of call types. The reality for individual businesses depends heavily on the urgency of the calls they receive.

A homeowner calling about a burst pipe is not leaving a voicemail and calling back tomorrow. A parent calling a dental clinic at 8 AM to book a child's appointment before school is not going to hold for four minutes. A customer calling to follow up on a quote they received last week has considerably more patience — they've already chosen you provisionally and are willing to wait.

The highest-risk calls for a small business — the ones most likely to be lost permanently if missed — are the first calls from a new potential customer with an immediate need. These callers have multiple alternatives and no prior loyalty to your business. The data on how quickly people move on is most relevant precisely for this group.

The Practical Takeaway

The research doesn't suggest that every missed call is a lost customer. Existing customers with ongoing relationships are more likely to leave a message or call back. Callers with non-urgent inquiries — requesting a quote, asking about pricing — are more patient than callers in emergency situations.

What the research does establish clearly is that the assumption "they'll call back" is not reliable for a significant portion of inbound calls — particularly for first-time callers, urgent situations, and after-hours contacts. Businesses that treat every call as a recoverable situation are likely overestimating how many of their unanswered calls translate into future bookings.

For businesses where first-call contact is commercially important — trades, clinics, service businesses taking bookings — the research supports building a system that answers calls rather than one that relies on callers' patience and follow-through.
