# Excel CEILING Function

The Excel CEILING function rounds a given number *up* to the nearest specified multiple. CEILING works like the MROUND function, but CEILING *always rounds up*.

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

The Excel CEILING function rounds a number up to a 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.

CEILING works like the MROUND function, but unlike MROUND, which rounds to the *nearest* multiple, CEILING *always rounds up*.

### 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 up to the next whole dollar, then subtract 1 cent, to 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 understands time formats and can be used to round time up to a given multiple. For example, to round a time in A1 up 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.
