'Die Ausgabe' is the noun related to the verb 'ausgeben' (to spend / to hand out / to publish). The meanings of the noun (money, edition, distribution) are derived from the meanings of the verb: to spend money, distribute something, or publish something.

How much money do you spend on groceries per month?
In the meaning 'Geldbetrag' (amount of money), the plural 'die Ausgaben' (expenses) is almost always used, often in contrast to 'die Einnahmen' (income/revenue). The singular 'eine Ausgabe' (an expense) is less common and refers to a single payment.
Wir müssen unsere monatlichen Ausgaben besser kontrollieren.
We need to control our monthly expenses better.
When a publication is meant, typical combinations are 'die aktuelle Ausgabe' (the current issue), 'die neueste Ausgabe' (the latest issue), or 'eine alte Ausgabe' (an old issue) of a newspaper or magazine.

Unfortunately, I missed the last issue of the magazine.
'Ausgabe' can refer to the action of distributing or to the place. The preposition 'an' (at), e.g., 'an der Ausgabe' (at the distribution point), is a clear signal for the place, while the action is often described without a preposition or with 'von' (of).

to cost / taste
Both words refer to money that is incurred for something. As a verb, „Kosten“ states what price something has or what amount is needed for it; „Ausgaben“ refers to the amounts of money that were actually paid. Use „kosten“ for the price and „Ausgaben“ for the payments made.
