# Excel MROUND Function

The Excel MROUND function returns a number rounded to a given multiple. MROUND will round a number up or down, depending on the nearest multiple.

*number*- The number that should be rounded.*significance*- The multiple to use when rounding.

The MROUND function rounds a number to the nearest given multiple. The multiple to use for rounding is provided as the *significance* argument. Rounding occurs when the remainder from dividing *number* by *significance* is greater than or equal to half the value of *significance. *If the number is already an exact multiple, no rounding occurs and the original number is returned.

The MROUND function takes two arguments, *number* and *significance*. *Number* is the numeric value to round. The *significance* argument is the multiple to which *number* should be rounded. In most cases, *significance* is provided as a numeric value, but MROUND can also understand time entered as text like "0:15" or "0:30". *Number *and *significance*** **must have the same sign, otherwise MROUND will return a #NUM! error.

### Examples

Below are some examples of MROUND formulas with hardcoded values:

To round a number in A1 to the nearest multiple of 5, you can use MROUND like this:

=MROUND(A1,5) // round to nearest 5

### Nearest negative number

To round negative numbers with MROUND, use a negative sign for significance:

### Nearest .99

MROUND can be used to round pricing to end with .99. The formula below will round a value in A1 to the nearest 1 dollar, subtract 1 cent, and return a final price like $2.99, $5.99, $49.99, etc.

=MROUND(A1,1) - 0.01 // round to nearest .99

### Nearest 15 minutes

MROUND can be used to round time. To round a time in A1 to the nearest 15 minutes, you can use a formula like this:

=MROUND(A1,"0:15") // round to nearest 15 min

### Rounding functions in Excel

Excel provides a number of functions for rounding:

- To round normally, use the ROUND function.
- To round to the nearest multiple, use the MROUND function.
- To round
*down*to the nearest specified*place*, use the ROUNDDOWN function. - To round
*down*to the nearest specified*multiple*, use the FLOOR function. - To round
*up*to the nearest specified*place*, use the ROUNDUP function. - To round
*up*to the nearest specified*multiple*, use the CEILING function. - To round
*down*and return an integer only, use the INT function. - To truncate decimal places, use the TRUNC function.

### Notes

- If a
*number*is already an exact multiple, no rounding occurs. - Rounding occurs when the remainder from dividing
*number*by*significance*is greater than or equal to half the value of*significance.* *Number*and*significance*- MROUND returns #NUM! if
*number*and*significance*are not the same sign. - MROUND returns #VALUE! if
*number*or*significance*is not numeric.
