## What Is Average Length of Stay (ALOS)?

In general, the term **Average Length of Stay** (**ALOS**) is defined as the length of stay in an average amount for a certain number of people.

**ALOS **is a key indicator in the hospital and hotel sector. Analyzing the data of each period of **ALOS **helps to determine the scope of improvement and efficiency. It can vary according to the type of facility or service offered. For example, the** ALOS** of a hospital will differentiate from the one of a hotel because each provides different categories of service.

## How to Calculate Average Length of Stay in Excel: Step-by-Step Process

In this section, we will describe the process for calculating the average length of stay in Excel with a step-by-step guideline. Carefully go through the procedure.

### Step 1: Insert In and Out Dates

To start the process, here is a hypothetical situation where we are considering 5 patientsâ€™ data records in a hospital.

- First, insert the
**Admission Time**and**Discharge Time**of each patient in**cell range C5:D9**.

### Step 2: Calculate Individual Length of Stay (LOS)

Now, we will find the duration of stay for each patient.

- In the beginning, insert this formula in
**cell E5**.

`=DATEDIF(C5, D5, "d")`

- Then, press
**Enter**. - Here, you will see the
**Length of Stay**for the first patient. - Next,
**left-click**on the bottom corner of**cell E5**and drag it to**cell E9**as shown in the image.

Here, we applied the **DATEDIF** function to calculate the total number of days between** cell C5** and **cell D5**.

- Finally, you will see all the outputs at once.

**Note:**If you need to count the duration in months or years, you can apply these formulas.

**LOS in Months: =DATEDIF(C5, D5, "m") **

**LOS in Years: =DATEDIF(C5, D5, "y")**

### Step 3: Find Total Length of Stay

At this stage, we will need to calculate the total length of stay that we found for each patient.

- In the beginning, insert this formula in
**cell E11**.

`=SUM(E5:E9)`

- Afterward, hit
**Enter**. - Thatâ€™s it, you will get the
**Total Length of Stay**(**LOS**).

Here, we used the **SUM** function to calculate the total value of the** cell range E5:E9**.

### Step 4: Calculate Average Length of Stay (ALOS)

Now, comes the final stage where we will calculate the average length of stay in Excel.

- First, insert this formula in
**cell E12**.

`=E11/5`

Here, we divided the **Total Length of Stay** by** 5** to find the **Average Length of Stay**. The dividend is **5** because the dataset shows the information on **5 patients**.

- Then, press
**Enter**. - Thatâ€™s it, you will finally get the value of the
**Average Length of Stay**for the**5 patients**in the hospital.

## Things to Remember

- It is very important to keep the format of all dates similar. Otherwise, it may show the wrong value.
- You can use a Summary Chart after this calculation to get a proper visualization.
