# 5 Ways to Round a Formula with SUM Function in Excel

The **ROUND function** returns a number rounded with specific digits in Excel. You can also use the **ROUND** function with other functions that perform mathematical operations on numbers in Excel, such as the **SUM function**. There are various ways to round a formula with the **SUM** function in Excel. In this article, we’ll outline the five best methods of doing it.

**To round the result of a formula that includes the SUM function in Excel, you can use the ROUND function. Here’s how:**

- Enter your formula with the
**SUM**function, like this:**=SUM(A1:A5)** - Use the
**ROUND**function to round the result to a specific number of decimal places. For example:**=ROUND(SUM(A1:A5), 2)** - Press
**ENTER**to calculate the rounded sum.

Now you have the sum of the numbers in the specified range rounded to the desired number of decimal places. It’s a simple way to control the precision of your calculations in Excel.

Here’s the dataset I’m going to use in this article. It’s got a list of some grocery items (in column **A**) with their prices (in column **B**) next to them. And at the end of the table, there’s an empty cell called **B9** for the **Total Price.**

## Round a Formula Having the SUM Function Using a Single Formula

Surely the easiest way to round a formula having the **SUM** function is to use both the **ROUND** function and **SUM** function in a single formula.

**Syntax**

=ROUND(SUM(number1,[number2],...), num_digits)

**Formula**

**=ROUND(SUM(B2:B8),2)**

**Step-by-Step Guide**

- Select an empty cell.
- Type the formula:
**=ROUND(SUM(B2:B8),2)** - Press
**ENTER**to see the result.

**Formula Explanation**

**B2:B8**is the range of selected cells.**2**refers that you want to keep**2**digits after the decimal point.

**Final Result**

The total price of all the grocery items is **$777.0600**.

**Note:** You may think the digits after the decimal is **.0600** where four digits are present. But **.0600 **and **.06** are the same numbers. You can also use the **Decrease Decimal** command to adjust the number of decimal places after the decimal point.

## Using the ROUND Function Separately to Round a Formula Having the SUM Function

This technique is also easy to remember. You will have to apply the **SUM** function and the **ROUND** function separately. The only extra work for this method is adding an additional cell below the data table.

**Syntax **

**=SUM(number1,[number2],...)**

**=ROUND(number, num_digits)**

**Step-by-Step Guide**

- In cell
**B9**, type the following formula:**=SUM(B2:B8)** - Press
**ENTER**. - Select another cell to apply the
**ROUND**function. - Now write the following formula in cell
**B10**:**=ROUND(B9,2)** - Press
**ENTER**to see the result.

**Formula Explanation**

**B9**is the target value.**2**means I want to round the number to**2**decimal places.

**Final Result**

Here is the final outcome. Take a look.

## Applying the ROUNDUP Function to Round a Formula with the SUM Function

In this method, I will be using a formula including both the **ROUNDUP** **function** and the **SUM** function. The **ROUNDUP** function is similar to the **ROUND** function. The only difference is **ROUNDUP** always rounds a number up.

**Syntax**

**=ROUNDUP(SUM(number1,[number2],...), num_digits)**

**Formula**

=ROUNDUP(SUM(B2:B8),1)

**Step-by-Step Guide**

- In cell
**B9**, enter the formula:**=ROUNDUP(SUM(B2:B8),1)** - Press
**ENTER**.

**Formula Explanation**

**B2:B8**is my selected cell range.**1**means I want to display**1**digit after the decimal point.

**Final Result**

Here the result is** $774.1000 **which has only one digit after the decimal.

## Applying the ROUNDDOWN Function to Round the Result of a Formula Having the SUM Function in Excel

The **ROUNDDOWN function** in Excel is used to round a number down to the specified number of decimal places.

**Syntax **

=ROUNDDOWN(SUM(number1,[number2],...), num_digits)

**Formula**

**=ROUNDDOWN(SUM(B2:B8),0)**

**Steps to Follow**

- Select cell
**B9**and write down the formula:**=ROUNDDOWN(SUM(B2:B8),0)** - Press the
**ENTER**key.

**Formula Explanation**

**B2:B8**is the selected cell range for this formula.**0**is the required number of digits after the decimal point.

In this particular case, I input **0** in the formula because I want a whole number as an outcome.

**Final Result**

Here is the final outcome in the image below:

## Manually Sum Values and Use the ROUND Function to Round the Result of the Formula

If you are unable to remember the above methods, then this method is likely to be suitable for you. In practical terms, this method will allow you to sum all the values manually and then round the result using the **ROUND** function.

**Syntax**

=cell(1)+cell(2)+...+cell(N)

=ROUND(number, num_digits)

**Steps to Follow**

- Select an empty cell (
**B9**). - Sum up all your target cells one after one with this formula:
**=B2+B3+B4+B5+B6+B7+B8** - Press
**ENTER**to apply the formula. - Now again select an empty cell. I have selected cell
**B10**. - Type the
**ROUND**formula:**=ROUND(B9,2)** - Press the
**ENTER**key.

**Formula Explanation**

**B9**holds the result of sum-up values.**0**is the required number of digits after the decimal point.

**Final Result**

This way you can use the **ROUND** function in Excel with sum to calculate your desired value.

## Frequently Asked Questions

### Why is Excel rounding my SUM?

Excel may round the **SUM** of numbers for several reasons:

**Cell Formatting:**Excel respects the formatting of cells. If cells have limited decimal places, the**SUM**will be displayed accordingly.**Precision of Source Data:**Rounding can occur if the source data in the cells has limited precision or if the numbers were entered or calculated with rounding.**Floating-Point Arithmetic:**Excel uses floating-point arithmetic, which may introduce small rounding errors, especially in complex calculations.**Rounding Functions:**If you use rounding functions like**ROUND**within your**SUM**formula, it explicitly instructs Excel to round the result.

To avoid rounding in Excel, adjust cell formatting, avoid using rounding functions, and ensure the source data has the required precision.

### Why is Excel changing the last number to 0?

Excel may change the last number to 0 due to cell formatting or data type issues. If the cell is formatted to display a fixed number of decimal places, it can round the number, making it appear as 0. Additionally, ensure that the cell is formatted as a number, not text, to allow for proper numerical operations, and review any formulas or input data for errors that might be causing the issue. Adjusting cell formatting and confirming data types can help prevent Excel from changing the last number to 0.

### How do I round numbers in Excel without a formula?

To round numbers in Excel without using a formula:

- Select the cell containing the number you want to round.
- Right-click the cell and choose “Format Cells.”
- In the “Format Cells” dialog, go to the “Number” tab.
- Under “Category,” select the desired number format.
- Adjust the decimal places as needed.
- Click “OK” to apply the formatting.

This method allows you to round numbers in Excel without using a formula by controlling how the number is displayed in the cell.
