Outside.
(But if the entire sentence is a parenthetical like this one, it would go inside.)
A period would go inside parentheses to finish a complete sentence, but you always need sentence-ending punctuation outside of the parentheses.
Write your sentence (then your parenthetical). Use the same punctuation inside the parentheses as you would outside of them and end the sentence with an ending punctuation mark (period).
put it outside.
Use a period to end the final sentence within the parenthetical, then use a period outside of the parenthetical to close the sentence in which the parenthetical takes place.
Use a period inside of the closing parenthesis to indicate that the sentence within the parentheses is ending. Use a period outside of the closing parenthesis to indicate that the sentence in which the parenthetical occurs is ending. Example: This was published in 1968 (Mary Jenkins looked it up.). or This was published in 1968. (Mary Jenkins looked it up.)

The entire sentence should be in parentheses, however the portion that is, should contain a period outside of the parentheses.
Use a period inside a parenthetical when the full sentence inside the parentheses ends.
In American English, periods typically go inside parentheses when the parenthetical phrase is a complete sentence. In British English, periods go outside parentheses unless they are part of the parenthetical sentence.
Periods should typically go on the outside of parentheses. However, if the entire sentence is contained within the parentheses, then the period should go inside.
put it outside.
No. Typically, you will only put ending punctuation (in this case, a period) if the sentence within the parentheses is a complete sentence.
In American English, a period goes inside the closing apostrophe when it ends a sentence. However, in British English, the period goes outside the closing apostrophe. For example, "I love eating pizza." (American English) or "I love eating pizza". (British English).
Use a period to end the final sentence within the parenthetical, then use a period outside of the parenthetical to close the sentence in which the parenthetical takes place.
If one or more sentences are between parentheses, then put the period or other final punctuation between the parentheses: Always thank the bellboy. (Usually you should also tip him.) Otherwise put the period or other final punctuation outside the final parenthesis: Always thank the bellboy (and any other staff who has aided you). The period or other final punctuation belongs to the sentence as a whole. If the entire sentence is within parentheses, naturally that includes the final punctuation. If the parentheses enclose only part of sentence, naturally the final punctuation goes outside.
Use a period inside of the closing parenthesis to indicate that the sentence within the parentheses is ending. Use a period outside of the closing parenthesis to indicate that the sentence in which the parenthetical occurs is ending. Example: This was published in 1968 (Mary Jenkins looked it up.). or This was published in 1968. (Mary Jenkins looked it up.)
