I have 2 fields:

1. dynamic field listing items with checkboxes - source is another 3rd field  

2. simple number field; for "Default Value" I want to calculate the count of selected items from above dynamic field. – Is this possible? Does field calculation allow for such functionality?

You need to use jQuery. https://formidableforms.com/knowledgebase/javascript-examples/#kb-count-number-of-checked-boxes

What about checkboxes with "other" option(s) available ? 
Flo Ubr replied 2 years ago

not sure if I understand your question/hint… but the answer by Victor to use a javascript worked.

Doesn`t work for checkboxes where "other" option is to be typed by the user (checkbox with custom text). It will not be count when it`s checked.

The "other" option is a checkbox that will be counted if you modify the jQuery example to do so. The jQuery looks at a checkbox's name and checked properties to determine the count. The selector for regular checkboxes is input[name='item_meta[643][]']:checked. To check for other, include input[name='item_meta[643][other_2]']:checked in the selector list like this modified example on pastebin: https://pastebin.com/rXYYBhHc
