### How To Calculate In Excel Sheet?

Let us see the steps to use Excel as calculator for calculating in a worksheet, with practical examples.

#### Example #1 – Use Formulas In Excel As A Calculator

We shall see an example of **Excel as average calculator** with formulas.

The table below shows the project points of students in three subjects.

And the requirement is to determine each student’s average project points based on the given data and display the output in column E.

Then, we can utilize **Excel as average calculator** by using the given data and the ‘**+**’ and ‘**/**’ operators in the target cells to achieve the required output.

**Step 1: **Select cell E3, enter the ‘**=**’ sign and the opening bracket, ‘**(**‘.

*=(*

Next, enter the first value, **9**, followed by the ‘**+**’ operator.

Next, enter the second value, **8**, followed by the ‘**+**’ operator.

And then, enter the third value, **9**, closing bracket, ‘**)**’, and the Forward Slash, ‘**/**’.

Next, since we must calculate the average of three values, enter **3** as the denominator.

**Step 2: **Press **Enter** to obtain the required average project points of the first student.

** Step 3: **Select cell E4, enter the following formula, and press

**Enter**.

*=(10+10+10)/3*

Likewise, select the remaining target cells one by one, enter the required formula, and press **Enter** to view the output for each student.

Thus, the above example shows we can use Excel as calculator for creating the required formulas using constants and arithmetic operators.

The formula in each target cell adds the three supplied project points. And then, it divides the sum by three to give the required average project points.

#### Example #2 – Use Cell References

We shall see an example of **Excel as difference calculator** using Excel cell references.

The table below shows each item’s maximum and minimum units, specified in column A, sold in January.

The requirement is to determine the difference between the maximum and minimum units of each item sold in January and display the output in column D.

Then, we can utilize **Excel as difference calculator**, using cell references and the ‘**–**‘ sign in the target cells.

**Step 1: **Select cell D2, enter the ‘**=**’, the cell reference to the first required value specified in column B, and the ‘**–**‘ sign.

*=B2-*

Next, enter the cell reference to the second required value specified in column C.

*=B2-C2*

** Step 2: **Press

**Enter**to view the difference between the two referenced values in the target cell.

**Step 3: **Drag the Excel fill handle down towards the last target cell.

The formula will get applied to the remaining target cells.

Thus, the above example shows we can utilize Excel as calculator for creating the required formulas using Excel cell references and arithmetic operators.

The Excel subtraction formula in each target cell deducts the second value from the first to give the required difference.

#### Example #3 – Cell Reference Formulas Are Flexible

The following example shows how cell references make formulas flexible when using Excel as calculator.

The table below lists a firm’s employees and their date of birth data.

And consider we use the inbuilt Excel function **YEAR**, in column C to utilize **Excel as year calculator**. The function accepts a date as the argument value to determine the employees’ birth years.

So, we select the target cell and enter the ‘**=**’, the function name **YEAR**, ‘**(**‘, cell reference to the date value in the corresponding row, and ‘**)**’. And then, press **Enter** to obtain the required birth year.

And using the Excel fill handle, update the formula in the remaining target cells.

Next, assume the date of birth of the employee, **Heather Walker** is incorrect. And we must update the correct date of birth and year.

Then, the steps are as follows:

** Step 1: **Double-click at the end of the date value in cell B5 to place the cursor inside the specific cell and be in edit mode.

The date value will be in the default Excel date format.

So, press **Backspace** and enter the correct year.

And once we press **Enter**, cell B5 will show the updated date. And the formula output in cell C5 gets updated automatically.

Thus, the above **Excel as year calculator** example shows that when we use cell references in formulas, we do not have to update the formulas manually for changes in the input data.

#### Example #4 – Formula Cell Is Not Value, It Is The Only Formula

The following Excel as calculator example explains what happens when we copy a cell containing a formula and try pasting its content into another cell.

The table below shows the 2022-23 sales at a firm’s branch offices.

And the requirement is to determine the total sales in each year and display the output in cells B8:C9 using the Excel status bar and the addition formula.

** Step 1: **Select the cell range B2:B7 to view the total of the chosen values in the bottom-right corner in the status bar,

**$213,000**.

And enter the sum of the **2022 Sales** values in cell B8.

**Step 2: **Select cell B9 and enter the following formula to add the **2022 Sales** values.

*=B2+B3+B4+B5+B6+B7*

And press **Enter** to view the formula output in the target cell B9, **$213,000**.

**Step 3: **Select cell B8 and use **Ctrl **+ **C **to copy the cell data.

Next, choose cell C8 and use **Ctrl **+ **V** to paste the copied data into the chosen cell.

We find the cell B8 value copied into cell C8 as the total **2023 Sales** value.

**Step 4: **Choose cell B9 and use **Ctrl **+ **C **to copy the cell data.

Next, select cell C9 and use **Ctrl **+ **V** to paste the copied data into the chosen cell.

The above step copies the cell B9 formula into cell C9, with the cell references updated in the copied formula, and we obtain the correct total of **2023 Sales **values in cell C9.

Thus, copying a formula containing cell references from a source cell into another applies the formula to the target cell instead of the source cell value.

#### Example #5 – Built-In Formulas Are Best Suited For Excel

We shall see an example of **Excel as hours calculator** to show that built-in functions help perform calculations quickly and error-free. And they are quite useful when the given dataset is massive and includes values in different formats.

For example, the table below lists tasks and their completion time details.

And the requirement is to determine the hour of completion of each task and display the output in column C.

Column B shows the task completion time data in unique formats. So, manually determining the required values will be an uphill task with a certain level of complexity.

Fortunately, Excel offers an inbuilt function, **HOUR**, to enable us to achieve the required output quickly when using **Excel as hours calculator**.

** Step 1: **Choose cell C2 and enter the

**HOUR()**.

*=HOUR(*

The **HOUR()** accepts the serial number equivalent to the time containing the required hour. And the input value can be a text string within double quotes, a decimal number, or other functions and formulas’ output.

Next, enter the cell reference to the required input value and close the bracket.

*=HOUR(B2)*

**Step 2: **Press **Enter** to view the **HOUR()** output in the target cell.

Furthermore, we can also enter the required inbuilt functions in a cell from the **Function Library** group in the **Formulas** tab.

**Step 3: **Using the fill handle, update the formula in the remaining target cells.

The cell C2 formula calculates 75% of 24 hours and returns the output **18**, which is 6 pm.

Next, the cell C3 formula accepts an input containing a date and time. So, the function returns the hour part of the date and time value, **20**, which is 8 pm.

Finally, the cell C4 formula input is a date. And as the time is not mentioned, Excel considers it 0 hours or 12 am. And hence, the function output in the specific target cell is **0**.

### Important Things To Note

- When using Excel as calculator, start a formula in a cell with the ‘=’ sign.
- Using constants to create formulas and then copying the formulas into another cell will not automatically update the formula output in the target cell. Thus, it is best to use cell references in the formulas when copying them into other cells.
- Use Excel inbuilt functions, wherever possible, to perform the calculations in a worksheet quickly and accurately.

### Frequently Asked Questions (FAQs)

**1. How to troubleshoot errors, such as #DIV/0! or #VALUE! when using Excel as calculator?**

We can troubleshoot errors, such as **#DIV/0! **or** #VALUE!** when using Excel as calculator with the following options from the **Formulas **tab:**•** **Trace Error****•** **Evaluate Formula**

For example, the following image shows two datasets.

We use ‘**/**’ to divide the cell A2 value by the cell B2 value in the target cell C2. And the formula results in the **#DIV/0!** error.

On the other hand, we use the **DATEDIF()** inbuilt function in the target cell I2 to determine the total number of days between the order and receive dates specified in cells G2 and H2. But the formula returns the **#VALUE!** error.

Here is how to troubleshoot the errors using the two methods mentioned above.**Step 1: **Select cell C2. And then choose **Formulas **– **Error Checking **drop-down – **Error Checking**.

The **Error Checking **window opens. And it shows the reason for the error.**Step 2: **With cell C2 selected, click **Formulas **– **Error Checking **drop-down – **Trace Error**.
