This can vary depending on the style guide and the country, but generally in the US, it's acceptable to put the period inside the quotations. (British English often places it outside.)


If you're including a citation, though, the period will come after the parenthetical citation and therefore outside the quote marks.

If you're creating dialogue with speaker tags, the period will likely need to be a comma.

Other punctuation, like question or exclamation marks, are pickier: they go inside the quotes if the original quote had them, but outside if it's your own question or exclamation.
