What Is a Good Call Answer Rate? 80% Within 20 Seconds, Under 5% Abandoned
By Sharrk Team · October 29, 2026
A good call answer rate is at least the contact-center standard of 80% of calls answered within 20 seconds, with fewer than 5% of callers hanging up before they reach someone. For a small or home-service business, treat that as the floor: every unanswered call is a customer who might call the next company, so aim to answer every call.
What is the standard call answer rate benchmark?
The most widely quoted target is "80/20": answer 80% of incoming calls within 20 seconds. Call Centre Helper calls it the traditional contact-centre target, and in its 2019 survey of more than 250 contact-centre professionals, the largest cluster of answers sat around 80/20, with other groups near 70/20 and 80/60. A New Zealand Office of the Auditor-General audit of a government contact centre also describes 80/20 as "one of the standard service level targets in the contact centre industry."
The number is a convention, not a law. COPC, a contact-center standards firm, argues in a 2024 article that 80/20 is "not likely" the right target for every operation and suggests working back from an acceptable abandonment rate instead.
| Metric | Common target | Where it comes from |
|---|---|---|
| Service level | 80% of calls answered within 20 seconds | Call Centre Helper (2019 survey); NZ Auditor-General |
| Abandonment rate, acceptable | About 3% to 5% | COPC (2024); NZ contact centre target of no more than 5% |
| Abandonment rate, benchmark range | 4% to 7% optimal; 6.9% median | MetricNet service desk benchmarks via HDI |
| Abandonment rate, highly responsive teams | 1% to 2% | Brad Cleveland, ICMI (2018) |
What is a good call abandonment rate?
Under 5% is a solid target, and the best-run teams get to 1% or 2%. MetricNet's service desk benchmark data, published by HDI, put the median abandonment rate at 6.9% and the average at 8.7%, and said customer satisfaction "begins to drop off significantly" once abandonment goes above roughly seven or eight percent. Brad Cleveland of ICMI wrote that highly responsive organizations see abandonment of "generally no more than one or two percent," and that no operation holds it at zero for long, because "any time there is a queue, there is opportunity for callers to abandon."
These figures come from staffed call centers with queues. A small business usually has no queue: the phone rings, then goes to voicemail. So for you, the useful question is simpler: of everyone who called, how many talked to a person (or an agent that could help them)?
What percentage of calls should a small business answer?
As close to 100% as you can get. The contact-center numbers above assume a caller will wait or call back. A homeowner with a leaking pipe or a broken AC usually won't. They will try the next name on the list. Our post on how many calls small businesses miss covers the research on how often that happens. The short version: missed calls are common, and voicemail does not make up for them.
Use 80/20 and under 5% abandonment as the minimum. If you're below that, you're behind what a typical call center delivers, and your callers will notice.
How do you calculate call answer rate?
You need three counts from your phone system for the same period: calls offered (every inbound call), calls answered by a person or agent, and calls abandoned (the caller hung up before anyone answered).
- Answer rate = calls answered ÷ calls offered × 100
- Abandonment rate = calls abandoned ÷ calls offered × 100
- Service level = calls answered within your target time (for example, 20 seconds) ÷ calls offered × 100
Calls that go to voicemail are not answered. Count them separately so you can see them. COPC also advises against two common shortcuts: dropping calls that hang up within the first few seconds, and calculating service level on calls handled instead of calls offered. Both make the numbers look better than what callers actually experienced.
Worked example (sample numbers)
Here's a made-up week for a plumbing company, Clearline Plumbing (sample):
| Count | Sample number |
|---|---|
| Inbound calls offered | 200 |
| Answered by a person | 150 |
| Answered within 20 seconds | 110 |
| Went to voicemail | 20 |
| Hung up before answer (abandoned) | 30 |
- Answer rate: 150 ÷ 200 = 75%
- Abandonment rate: 30 ÷ 200 = 15%
- Service level (20 seconds): 110 ÷ 200 = 55%
- Unanswered overall (voicemail plus abandoned): 50 ÷ 200 = 25%
Clearline (sample) is well short of 80/20 and triple the 5% abandonment target. One in four callers never reached anyone.
How do you measure answer rate from your phone system?
Most business phone and VoIP systems keep a call log or call report. Here's how to get a reliable number:
- Export two to four weeks of inbound calls. One week can be thrown off by a holiday or a storm.
- Sort by call result. Labels vary, but you are looking for answered, missed or abandoned, and voicemail. Leave outbound calls out.
- Check ring or wait time on answered calls. If your system records it, count how many were answered within 20 seconds. That gives you your service level. (Our post on how many rings before answering covers what that means in rings.)
- Split by hour and day. Most businesses find missed calls bunch up at lunch, early morning, evenings and weekends. That tells you when you need coverage.
- Count unique callers too. One person calling three times shows up as three calls. Comparing unique callers with total calls shows how many people gave up for good.
- Track it every month. Pick one formula and stick with it, so the trend means something.
If your phone system doesn't report abandoned calls separately, count "missed" plus "voicemail" as unanswered. Then use that figure as your answer-rate gap.
How does Sharrk help you answer every call?
Sharrk's AI voice agents answer every call 24/7, so after-hours, lunch-rush and overflow calls get picked up instead of going to voicemail. The agent answers from your knowledge base (prices, service area, hours), takes messages, sends email or text alerts, and can live-transfer to a person with a cold or warm transfer. Call logs show each call's transcript, recording and captured details, and per-agent metrics include answer, booking and transfer rates and your busiest hours, so you can measure answer rate instead of guessing. See how it works on our AI answering service page.
Mako, Sharrk's AI assistant, builds the agent from plain English. Describe your business and how you want calls handled. Mako shows each change on an Apply card, waits for your OK, and lets you undo changes. You write or edit the greeting, so the agent can introduce itself as an AI assistant in its first sentence.

Frequently asked questions
What is a good call answer rate?
A good call answer rate is at least 80% of calls answered within 20 seconds, the traditional contact-center target, with under 5% of callers hanging up first. Small businesses that depend on phone leads should aim to answer nearly every call.
What is an acceptable call abandonment rate?
Under 5% is an acceptable call abandonment rate for most businesses. COPC puts acceptable abandonment at about 3% to 5%, MetricNet benchmarks found a 6.9% median, and ICMI's Brad Cleveland notes highly responsive organizations see 1% to 2%.
How do you calculate call answer rate?
Divide calls answered by total inbound calls offered and multiply by 100. For example (sample numbers), 150 answered out of 200 calls is a 75% answer rate. Calls that go to voicemail do not count as answered.
Does a call that goes to voicemail count as answered?
No, a call that goes to voicemail is not answered. Count voicemail calls separately so you can see how many callers never reached a person.
Is 80/20 the right service level for every business?
Not necessarily. 80/20 is the most common convention, but COPC suggests setting your target from an acceptable abandonment rate and your own call history. For small businesses where each call may be a new job, aim higher than 80/20.
How can Sharrk help my answer rate?
Sharrk's AI voice agents answer every call 24/7 and can live-transfer to a person. Call logs and per-agent metrics show answer, booking and transfer rates and your busiest hours.
