# Round by bundle size

=CEILING(number,bundle)/bundle

To round up to the next bundle size, you can use the CEILING function which automatically rounds up away from zero.

In the example shown, we need a certain number of items, and the items come in specific bundle sizes. To calculate how many items are needed, taking into account the bundle size, the formula in D5 is:

=CEILING(B5,C5)/C5

### How this formula works

The gist of this formula is that it figures out bundles needed, given items needed, and a specific bundle size.

For example, if you need 6 items, and the bundle size is 2, you'll need 3 bundles. If you need 3 items, and the bundle size is 5, you'll need 1 bundle (and you'll end up with 2 extra items).

First, we use the CEILING function get an item count needed, taking into account the bundle size.

=CEILING(B5,C5)

The CEILING function is fully automatic. It will round a number up until it reaches a number evenly divisible by a given multiple (bundle in this case).

Finally, we divide the number provided by CEILING by the orignal bundle size.

The result is the the total number of bundles required.
