A rounded number.

Syntax

=CEILING (number, multiple)

Arguments

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

Usage notes

The Excel CEILING function rounds a number up to a given multiple.

Example #1 - round up to nearest 5

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

=CEILING(A1,5)

Example #2 - round pricing up to end with .99

CEILING can be a can be useful to set pricing after currency conversion or discounts are applied. For example, the formula below will round a value in A1 to the nearest 1 dollar, then subtract 1 cent, and return a price like $2.99, $5.99, $49.99, etc.

=CEILING(A1,1) - 0.01

Example #3 - round time up to nearest 15 minutes

CEILING can be used to round time up to a given multiple. For example, to round a time in A1 down to the nearest 15 minutes, you can use CEILING like this:

=CEILING(A1,"0:15") // round up 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

CEILING works like the MROUND function, but CEILING always rounds up.
If number is an exact multiple of significance, no rounding occurs.
If number and significance are both negative, CEILING rounds down, away from zero.
If number is negative, and significance is positive, CEILING rounds up, towards zero.
For more control over how CEILING rounds negative numbers, see the CEILING.MATH function.
