Rounding numbers in Excel is a task that can be accomplished in a few easy steps. By using Excel’s built-in rounding functions, you can quickly round numbers to the nearest whole number, decimal place, or multiple of a number. This overview will help you understand how to round numbers in Excel and make your data more presentable and easier to analyze.
Step by Step Tutorial: How to Round Numbers in Excel
Before we dive into the steps, let’s understand what we are about to do. Rounding numbers in Excel helps to simplify your data, making it easier to read and analyze. Whether you’re dealing with financial figures, measurements, or any other numerical data, rounding can be quite helpful.
Step 1: Select the cell with the number you want to round
Click on the cell that contains the number you wish to round.
When you select the cell, make sure that the number is in a format that Excel can round. For example, if it’s a date or a text, it won’t work. It has to be a numerical value.
Step 2: Use the =ROUND() function
In the formula bar, type =ROUND(Number, Num_digits) and press Enter.
The ROUND function is one of several rounding functions in Excel. The “Number” is the value you want to round, and “Num_digits” is the number of digits to which you want to round the number.
Step 3: Input the number you want to round
Replace “Number” in the formula with the cell reference of the number you want to round.
For instance, if the number you want to round is in cell A1, your formula should look like =ROUND(A1, Num_digits).
Step 4: Input the number of decimal places
Replace “Num_digits” with the number of decimal places you want to round to.
If you want to round to the nearest whole number, you would use 0 as your Num_digits. If you want to round to two decimal places, you would use 2, and so on.
Step 5: Press Enter to apply the rounding
Once you have completed the formula, hit Enter to round the number.
After pressing Enter, the cell will display the rounded number according to the parameters you set. The original number will still be in the formula bar, but the rounded number will be what’s displayed in the cell.
After completing these steps, the number in your selected cell will be rounded to the nearest specified decimal place or whole number. This can help make your data more readable and can be especially useful when dealing with financial figures or measurements.
Tips for Rounding Numbers in Excel
- Use the =ROUNDUP() function to always round numbers up.
- Use the =ROUNDDOWN() function to always round numbers down.
- Remember that rounding numbers can affect the accuracy of your data, so use it thoughtfully.
- For rounding to the nearest multiple of a number, use the =MROUND() function.
- If you want to round numbers without altering the original data, consider using formatting options to display rounded numbers instead.
Frequently Asked Questions

ROUND rounds numbers to the nearest specified decimal place or whole number. ROUNDUP always rounds numbers up, and ROUNDDOWN always rounds numbers down, regardless of the value of the digit following the specified decimal place.
Can I round to the nearest multiple of a number in Excel?
Yes, you can use the =MROUND() function to round to the nearest multiple of a specified number.
Is there a way to round numbers without changing the actual value?
Yes, you can use Excel’s formatting options to display rounded numbers without altering the actual cell value.
Can I round an entire column of numbers at once?
Yes, you can apply the rounding function to one cell and then drag the fill handle down to apply the same function to the entire column.
Does rounding affect the accuracy of my data?
Yes, rounding can affect the accuracy of your data, so it should be used thoughtfully and appropriately based on the context of the data.
