You should always make the distinction between a compound word (such as homework) which is one word, and a hyphenated word, such as cross-reference, which is listed in the dictionary as one word, but is made from two words.
Hyphenated words are two separate words linked to create a new word, or combined to form a common adjective. For example, on-site is an adjective meaning done on the site. Similarly, a low-budget film is neither a low film or a budget film.
Hyphens are generally not used for verb pairs such as count down or mix up, but the nouns are one word (countdown, mixup).
Some compound words such as makeup and homestyle have hyphenated variants that mean the same thing. Over time, many paired words become hyphenated and later may become one word.
