The [Call Abandonment Rate Calculator](https://edesy.in/tools/call-abandonment-rate-calculator) measures your abandonment rate from call counts, with an adjusted rate that excludes short hang-ups, and estimates the revenue at risk from abandoned callers you did not recover.

## How to Use

1. Under "These counts are for one", choose **Day**, **Week** or **Month**.
2. Enter **Calls offered** and **Calls abandoned**.
3. Set the **Short abandon threshold** in seconds, and optionally the number of calls **Abandoned within** that many seconds.
4. Optionally enter **Abandoned calls recovered**.
5. Under "Revenue at risk from unrecovered hang-ups", enter the share of abandoned callers who were a potential sale or booking, and the average value of one sale or booking.

## Inputs

- **Calls offered**: calls that reached the queue or agent group, answered or not. Leave out calls that ended in the IVR menu by choice.
- **Calls abandoned**: callers who hung up before an agent answered. Must not exceed calls offered.
- **Short abandon threshold**: hang-ups faster than this are usually misdials or callers who changed their mind. Default 5 seconds.
- **Abandoned within the threshold**: part of the abandoned count. Leave at 0 if your system does not report it.
- **Recovered**: abandoned callers you called back and reached, or who called back and got through. Count each caller once.
- **Share that were a sale** and **Average value**: your own estimates. The defaults (30% and 1,500 rupees) are examples.

## Reading the results

```
Abandonment rate = abandoned / offered x 100
Adjusted rate = (abandoned - short) / (offered - short) x 100
Revenue at risk = (abandoned - recovered) x share that were sales x average value
```

- **Abandonment rate** and **Adjusted rate**, with the gap in percentage points when you enter short abandons.
- **Calls answered** and the answer rate.
- **Abandoned, not recovered** and the share of abandoned calls recovered.
- **Revenue at risk** for the period you chose.

## Things to know

- When reporting the adjusted rate, state the threshold you used and keep the raw rate next to it so numbers stay comparable.
- Short abandons or recovered calls larger than the abandoned count show a warning and hide the affected results.
- Customers lost for good, repeat calls and agent cost are not included.
- This tool measures a rate you already have. To model what longer hold times cost, use the hold time cost calculator.
