Reading your bank fees and statements without getting ripped off. 6 chapters and a final quiz.

Your bank statement is a technical document nobody ever taught you to read, and your bank fees are often buried in it. This course decodes the account statement line by line and walks through the catalog of fees: account maintenance, payment incidents, overdrafts, and spending abroad. It explains the mandatory annual fee statement, and details the legal caps and the special offer for financially vulnerable customers. Finally, it shows how to compare, negotiate, and switch banks using France's bank switching service.

Chapter 1. Decoding your account statement.

Your account statement is the official record of your money. Everything goes through it. The wording is abbreviated, the columns are technical, and the dates don't mean what you think. Learning to read it puts you back in control: you can spot an error, make sense of a surprise debit, and above all track down the fees that slip in quietly.

This flow explains why a card payment can show up several days after the purchase. There's a gap between authorization, when the merchant checks that the card is valid, and clearing, which produces the actual debit. That's perfectly normal. Your displayed balance doesn't always reflect the money you've actually committed.

⚠️
Value dates: the fine print that costs you interest
The value date is the date used to calculate interest. For a transfer or direct debit, the law requires it to match the transaction date (Article L133-14 of the French Monetary and Financial Code). When your account is overdrawn, the order of value dates affects your overdraft interest: a credit dated “late” and a debit dated “early” inflate the bill. Check them if you're often overdrawn.

What to do with a cryptic description
When you don't recognize a debit, search for the description online before crying fraud. It's often the legal name of a company, such as a retailer's parent company or a payment platform, rather than the brand you saw in the store. If you're still unsure, contact your bank. You have 13 months to dispute an unauthorized debit and 8 weeks to dispute an authorized direct debit.
