CEILING function

This article describes the formula syntax and usage of the CEILING function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.


Returns number rounded up, away from zero, to the nearest multiple of significance. For example, if you want to avoid using pennies in your prices and your product is priced at $4.42, use the formula =CEILING(4.42,0.05) to round prices up to the nearest nickel.


CEILING(number, significance)

The CEILING function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • Number    Required. The value you want to round.
  • Significance    Required. The multiple to which you want to round.


  • If either argument is nonnumeric, CEILING returns the #VALUE! error value.
  • Regardless of the sign of number, a value is rounded up when adjusted away from zero. If number is an exact multiple of significance, no rounding occurs.
  • If number is negative, and significance is negative, the value is rounded down, away from zero.
  • If number is negative, and significance is positive, the value is rounded up towards zero.


The example may be easier to understand if you copy it to a blank worksheet.
