Do you need to file an FBAR?

A one-minute check, no account. A U.S. person must file an FBAR if their foreign accounts, added together, were worth more than $10,000 at any point in the year.

Are you a U.S. person (citizen, resident, or a U.S. entity)?

Add up the most each foreign account was worth at any point during the year. Not the year-end balance.

A guide, not advice. Based on the FBAR rules (FinCEN Report 114; IRS FBAR overview).
