How to Round a Number to Closest ten in Excel

Rounding a number in Excel is very easy. There are situation wherein we need to round a number to closest 10 or 100. For example, if we have a number 115 then 120, if we have 112 then 110. For this there is a dedicated function in Excel called MROUND which comes useful for such scenario. Let us learn more about the function MROUND in Excel.

Syntax of Excel MROUND function

MROUND(number, multiple)

Where,

  • Number Required. The value to round.
  • Multiple Required. The multiple to which you want to round number.

Note: MROUND rounds up, away from zero, if the remainder of dividing number by multiple is greater than or equal to half the value of multiple.

Example:

Below are the few useful examples of MROUND in Excel.

1. Rounding a number to multiples of 10

=MROUND(112, 10) Rounds 112 to the nearest multiple of 10 which will return 110

=MROUND(116, 10) Rounds 116 to the nearest multiple of 10 which will return 120

2. Rounding a number to multiples of 5

=MROUND(112, 5) Rounds 112 to the nearest multiple of 5 which will return 110.
