# MROUND Function – Google Sheets

The MROUND function in Google Sheets rounds a number to the nearest multiple of a specified factor. This rounding can be helpful in various scenarios, such as rounding prices to the nearest nickel or rounding time to the nearest half-hour.

Rounding occurs when the remainder from dividing the value by factor is greater than or equal to half the value of the factor. If the `value` is already an exact multiple, no rounding occurs, and Google Sheets returns the original `value`.

## Syntax

`=MROUND(value, factor)`

`value` – The number for the function to round

`factor` – The multiple to round with

## Similar Functions

Several functions deal with rounding. Choose the most appropriate for your use.

• CEILING – Rounds a number up to the nearest integer multiple of specified significance
• INT – Rounds a number down to the nearest integer
• FLOOR – Rounds a number down to the nearest integer multiple of specified significance
• MROUND – Rounds one number to the nearest integer multiple of another
• ROUND – Round a number to a specified number of decimal places using standard rounding
• ROUNDDOWN – Round a number down to a specified number of places
• ROUNDUP – Round a number up to a specified number of places
• TRUNC: Truncates a number to a certain number of significant digits by omitting less significant digits

## Possible Errors

#NUM! – The value and the factor are different signs. Make both positive or negative.

## Examples

You can use MROUND in many different ways. Let’s take a look at a few, starting with rounding currency.

### Example 1 – Round to the Nearest Nickel

Sometimes it looks better to present a price rounded to the nearest nickel. Let’s look at how to do that.

The formula used in cell C2: `=MROUND(A2,B2)`

We use the MROUND function to divide the Original Price by the factor of `\$0.05`. Since the function uses standard rounding (instead of rounding up or down), it rounds `\$1.21` down to \$1.20 in row 2 and rounds `\$1.23` up to \$1.25 in row 3. Google Sheets does not round the last value in column A because it is already a multiple of `\$0.05`.

### Example 2 – Round to the Nearest Half Hour

Next, let’s round some time values. It is common to refer to a time as a rounded value. In this example, we’ll round values to the closest half-hour.

⚠️ You can enter a half hour as “`0:30`” or “`0:30:00`“. Either way, you’ll need to use custom formatting to remove the seconds, like in the example above in column B.

Rows 2 and 3 both round to 1:30 following the standard rounding rules of rounding to the nearest value. As `1:45 PM` is halfway between 1:30 PM and 2:00 PM, the MROUND function rounds it up to 2:00 PM.

### Example 3 – Round With Different Factors

Up to this point, we have been changing the `value`. Now let’s look at changing the `factor`. We’ll use positive and negative `factors` to see the differences.
