Round a number up to nearest multiple

Excel formula: Round a number up to nearest multiple
Generic formula 
=CEILING(number,multiple)
Summary 

To round a number up to the nearest specified multiple (i.e. round a price up to the nearest dollar) you can use the CEILING function. In the example shown, the formula in cell D6 is:

=CEILING(B6,C6)
Explanation 

The Excel CEILING function rounds a number up to a given multiple. The multiple to use for rounding is given as the second argument (significance). If the number is already an exact multiple, no rounding occurs.  CEILING works like the MROUND function, but unlike MROUND, which rounds to the nearest multiple, CEILING always rounds up to the given multiple.

In the example shown, the formula in cell D6 is

=CEILING(B6,C6)

This tells Excel to take the value in B6 ($33.39 ) and round it to the nearest multiple of the value in C6 (5). The result is $35.00, since 35 is the next multiple of 5 after 33.39. In cell D10, we are rounding the same number, 33.39 up to the nearest multiple of 1 and get 34.00.

You can use CEILING to round prices, times, instrument readings or any other numeric value.

CEILING rounds up using the multiple supplied. You can use the MROUND function to round to the nearest multiple and the FLOOR function to round down to a multiple.
