Round Numbers To The Nearest Multiple

Round to Nearest Multiple








When you need to round a number to a specified multiple, such as rounding a price to the nearest 5¢ or rounding a time to the nearest 15 minutes, Excel’s MROUND is the answer.

For example, several years ago in Canada our 1 cent coin was discontinued, so most cash transactions are now rounded to the nearest 5 cents.

Syntax for the MROUND Function:

There are two arguments in the MROUND function. number is the number that you want to round. multiple is the multiple to use when rounding.

The MROUND function rounds a number to the nearest multiple of the second argument. For example, in the above example, all retail prices have to be rounded to the nearest 5¢. To calculate the retail prices for all products we use this MROUND formula…

Using MROUND for Time
You can also use the MROUND function to round a time to a specified increment. If you want to round a time to the nearest 15 minutes, use the formula…

Using MROUND with Negative numbers
Keep in mind that both arguments in the MROUND function must have the same sign. Therefore, if cells referenced by MROUND have a mix of positive and negative amounts, you will need to multiply the second argument by the sign of the first argument using the SIGN function.

In the example below, =MROUND(A5,0.25*SIGN(A5)) will work for both positive and negative values. The SIGN function returns a 1 if the sign is positive and -1 if the sign is negative.
