CEILING.MATH: Excel Formulas Explained

As a marketer, I love spreadsheets. They're essential tools for staying organized, tracking progress, and making important decisions. With Excel, you can do so much more than just add and subtract numbers. One Excel formula that has caught my attention is the CEILING.MATH function. It's a game-changer, and I'm excited to share what I've learned about it so far.


CEILING.MATH is an Excel formula that rounds numbers up to a specified multiple. For example, if you have a list of numbers and you want to round them all up to the nearest 10, CEILING.MATH can do that for you. It's similar to the ROUNDUP function, but with some added flexibility.


Using CEILING.MATH is easy. Here's the basic syntax:

=CEILING.MATH(number, significance)

The "number" argument is the cell or value you want to round up. The "significance" argument is the multiple to which you want to round up. For example, if you want to round up to the nearest 10, you would use 10 as the significance.

Let's say I have a list of prices for products I sell:

Product Price Rounded Price
Widget A 8.95 =CEILING.MATH(B2, 1)
Widget B 12.75 =CEILING.MATH(B3, 5)
Widget C 21.50 =CEILING.MATH(B4, 10)

In this example, I want to round up all prices to the nearest dollar. For Widget A, I use a significance value of 1. For Widget B, I use a significance value of 5. For Widget C, I use a significance value of 10. The result is a list of rounded prices that are all easier to work with. No more fractions of a cent to deal with!

Other Uses for CEILING.MATH

CEILING.MATH isn't just for rounding prices. You can use it for all sorts of calculations. For example:

  • Round up a list of grades to the nearest letter grade
  • Round up quantities to the nearest package size
  • Calculate how many people can fit in a room based on the square footage and the maximum occupancy limit per person

The possibilities are endless!


CEILING.MATH is a powerful tool that can make your life easier. It's easy to use and it can save you time and headache. Whether you're a marketer like me or just someone who loves spreadsheets, I highly recommend giving it a try. Who knows, it might just change the way you think about Excel formulas forever.
