Average Handle Time : Definition and Calculation

In call center language Average Handle Time is also known as AHT. Some organizations also use the term ACHT which stands for Average Call Handling Time. So Average Handle Time is the time that a call center executive takes to complete an interaction with a customer. In simpler terms AHT is the time from where the call center executive answers the call to the point where he finishes the call and fills the relevant documentation for that customer and is ready to attend the next call.

Formula to calculate Average Handle Time for a single call:

Handling Time = Talk Time + Hold Time + After Call Work Time

So Handling Time is the sum of Talk Time, Hold Time and After Call Work Time.

Let me explain the above mentioned terms:

Average Talk Time also known as ATT is the total time a call center executive is talking to a customer.

Average Hold Time is the time for which a call center executive puts the customer on hold by pressing the Hold key on his phone. Keep in mind that blank or dead air does not count as hold time, it is added to the talk time or ATT.

After Call Work Time also known as ACW is the time the call center executive spends to complete customer documentation or tagging into the CRM tool.

How to calculate AHT

The formula shared above holds good for a single call or interaction. Now if you have to calculate the Average Handle Time for an executive for a whole day the formula will be the sum of Handling time of all the calls of that executive for the day divided by the total calls answered by that executive. For example if Charles answered three calls in a day with the following durations:

Call 1 = 100 second

Call 2: 150 seconds

Call 3: 200 Seconds

Then AHT for Charles for the day will be (100+150+200)/3 which is 150 seconds

Another way to calculate the AHT is that you calculate Average Talk Time ATT of all calls that is sum of Talk Time of all calls divided by total answered calls,

Average Hold Time of all Calls and Average ACW of all calls and then add the three.

i have agent ATT+ACW+AHT in timing format like 0:12:36 so how do calculate overall AHT in sec kindly let me know the formula for that

• Ashish Singla

There is a simple trick to it, Simply multiply each value with 86400 and this will automatically convert it to seconds. Then simply add all of them. If you still face any problem do let me know.

• Piku

Y 86400 in a hour 1 min 60 sec then how

• Ashish Singla

Because most ACD reports follow Hour:Minute: Seconds format and hence to convert to seconds you need to multiply with 86400

• Sunny

Use sumproduct function n if u do now then please let me know

2. shashi kant

how did you calculate 86400 ? Kindly let me know about it

• jai

60 x 60 x 24 = 86400

Hi,,
very easy to understand AHT I personally appreciate the way you use to explains .
thanks

I am needing help. I am having to create a spread sheet but the issue is i am having issues on how to get it down to the second with the total talk time 1957:53:12
total after call work was 3778:30:22
total hold time was 2062:09:55.
I am not sure how to get it sown to the second.

• Ashish Singla

Simply multiply these values with 86400 to convert to seconds

6. Paul

I’m curious, how to consider hold time ,talk time, outbound call (callback) in AHT? I’m an inbound support but we are allowed to call customer back if line gets disconnected.
Supposing i have 5mins call inbound,
5X60=300sec
and I have 3mins outbound call
3X60= 180sec
so should I add it or there’s a different computation in getting the average of inbound and outbound call

• Ashish Singla

Hold time and talk time are two parameters that remain the same in case of outbound and inbound. Although dial time and preview time are additional parameters for outbound

• Amandeep Sokhi

Paul,

If you add the outbound talk time and hold time, then it would be loaded AHT.

The normal AHT which includes inbound calls is unloaded AHT.

So it’s on your business requirement what sort of AHT is required by client.

What if , AHT of 10 calls = 200 seconds
Aht of 20 calls = 300 seconds
Aht of 30 calls = 400 seconds

Then what is the overall Aht?

• Ashish Singla

The AHT for the above scenario will be calculated as follows:
Total calls= 10+20+30= 60
total handling time= (10*200) + (20*300) + (30*400) = 20000
So AHT will be = 20000/60= 333.33 secs

If my aht is 450 sec, my hold is 30seconds and my acw is 10 sec what would my my talk time. Can someone give me the formula? Thanks

• Ashish Singla

Your ATT or average talk time will be AHT-hold time-ACW time that is 450-30-10= 410 seconds

9. Sunny

You can use sumproduct function

10. Liz

i wish to calculate forecasted FTE without AHT being factored into the equation. what calculation would I use to remove AHT from my forecast?

• Ashish Singla

Well, it will not be very accurate. But if you still want it, you will have to see the average number of calls that a FTE is currently taking per day. Then simply dvinde the daily forecased calls by this figure:
formula would be :
Number of FTE required= Daily forecasted calls/ avg calls taken by FTE in a day

Hi all
What is the current best practices for abandoned call rate for contact center. I mean the percentages

• Ashish Singla

Well there is no thumb rule for it, but generally a service level of 80:20 is considered to be a good value and hence an abandon rate of less than 5% is considered good.
