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. If the number is already an exact multiple, no rounding occurs and the original number is returned.
Example #1 - round to nearest 5
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
Example #2 - round pricing to 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
Example #3 - round time to 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
