The CEILING function in Google Sheets rounds a number up to the nearest integer multiple of a specified significance.
If the value is negative, and the factor is negative, this function rounds the value down, away from zero.

Syntax
=CEILING(value, factor)
value – The number for the function to round
factor – The multiple to round up to

Possible Errors
#NUM! – The value and the factor are different signs. Make both positive or negative.
#VALUE! – An argument is non-numeric.
Examples
You can use CEILING in many different ways. Let’s take a look at a few, starting with rounding currency.
Example 1 – Round Up to the Next Nickel
Sometimes presenting a price rounded up to the next nickel looks better. Let’s look at how to do that.
The formula used in cell C2: =CEILING(A2,B2)
We use the CEILING function to round the Original Price to a factor of $0.05. Since the function rounds up, it rounds $1.23 up to $1.25 in row 2 and rounds $1.27 up to $1.30 in row 4. Google Sheets does not round the value in row 3 because $1.25 is already a multiple of $0.05.
Example 2 – Round Up to the Nearest Half-Hour
Next, let’s round some time values. It is common to refer to a time as a rounded value. In this example, we’ll round values up to the next half-hour.
The formula used in cell C2: =CEILING(A2,B2)
⚠️ You can enter a half hour as “0:30” or “0:30:00“. Either way, you’ll need to use custom formatting to remove the seconds, like in the example above in column B.
Rows 2 and 4 both get rounded up to the next half hour. As 1:30 PM is already a multiple of 30 minutes, the CEILING function does not change it.
Example 3 – Round With Different Factors
Up to this point, we have been changing the value. Now let’s look at changing the factor. We’ll use positive and negative factors to see the differences.
You can see that negatives and positives move towards the same absolute values. Each output in column C is the opposite sign when the inputs flip their signs.
