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.

Introduction to Dataset

Here is the dataset that I am going to use for this article. The dataset has a list of a few grocery items (column A) and their prices (column B) beside them. And, at the bottom of the data table, there is an empty cell (B9) for calculating the Total Price.

Quickest Way to Round a Formula with SUM Function

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)

Usage Guide

Step_1: Select an empty cell (B9).

Step_2: Type the formula in cell B9.

Step_3: Press ENTER to insert the formula.

Quickest Way to Round Formula in Excel with Sum Formula


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.

Alternative Way #1: Using the SUM function and Round Function Separately

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)

Usage Guide

Step_1: In cell B9, type the following formula:

=SUM(B2:B8)

Step_2: Press ENTER.


Formula Explanation

Here B2:B8 is my selected cell range that I want to sum up.


Step_3: Select another cell to apply the ROUND function.

Step_4: Now write the following formula in cell B10:

=ROUND(B9,2)

Step_5: 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.

Alternative Way #2: Apply the ROUNDUP Function to Round Formula with 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)

Usage Guide

Step_1: In cell B9, enter the formula.

Step_2: Press ENTER.

Use the ROUNDUP Function to Round Formula in Excel with Sum


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.

Alternative Way #3: Apply the ROUNDDOWN Function to Round Formula in Excel with SUM Function

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)

Usage Guide

Step_1: At first select cell B9 then write down the formula.

Step_2: Press the ENTER key.

Apply the ROUNDDOWN Function to Round Formula in Excel with Sum


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:

Alternative Way #4: Manually Sum Values and Use ROUND function

If you can not memorize the above methods, this technique is probably best for you. Technically, this method will help you to manually sum up all the values and then round up the result with a ROUND function.

Syntax

=cell(1)+cell(2)+...+cell(N)
=ROUND(number, num_digits)

Usage Guide

Step_1: Select an empty cell (B9).

Step_2: Sum up all your target cells one after one with this formula:

=B2+B3+B4+B5+B6+B7+B8

Step_3: Press ENTER to apply the formula.

Use the Manual Sum Method in Excel

Step_4: Now again select an empty cell.

I have selected cell B10.

Step_5: Type the ROUND formula in cell B10:

=ROUND(B9,2)

Step_6: Press the ENTER key.

 Sum Method and ROUND function in Excel


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.
