MROUND Function

Returns a number rounded to a specified multiple

What is the MROUND Function?

The MROUND function is categorized under Math and Trigonometry functions. The function will return a number rounded to a multiple given by the user. MROUND will always round up away from zero.

As a financial analyst, the MROUND function helps round a number and eliminate the least significant digits, making it simpler but keeping close to the original value.



=MROUND(number, multiple)


The MROUND function uses the following arguments:

  1. Number (required argument) – It is the number that needs to be rounded.
  2. Multiple (required argument) – It is the multiple to which we want to round a number.


How to use the MROUND Function in Excel?

To understand the uses of the MROUND function, let’s consider a few examples:


Example 1

Suppose we are given the following data:


MROUND Function

The results in MS Excel are shown below:


MROUND Function - Example 1


Example 2

Let’s see how the MROUND function can be used to get a time rounded up to the nearest 30-minute interval. Suppose we are given the data below:


MROUND Function - Example 2


The formula used is shown below:


MROUND Function - Example 2a


We get the result below:


MROUND Function - Example 2b


When we supply “0:30” as the multiple, Excel will internally convert 0:30 into 0.0208333333333333, which is the decimal value that represents 30 minutes.

We can also express 30 minutes in a formula using the formula =30/(60*24).

Alternatively, depending on the requirements, we can use the formula to round to different time intervals such as the nearest 15 minutes or 1 hour.


Few notes about the MROUND Function 

  1. MROUND rounds up away from zero.
  2. The number and multiple arguments must be of the same sign.
  3. #NUM! error – Occurs when the number and multiple arguments are not of the same sign.
