Hermès does not publish an official formula. Most clients focus on non-bag purchases for a cleaner view of their broader purchase history.
The best approach is to be consistent. Choose your tracking rules and apply them the same way every time.
Your included non-bag spend divided by your target bag price. A 1.0:1 ratio means you have spent the same amount as your bag. 2.0:1 means twice that amount.
The ratio measures your non-bag purchase history. Counting bags themselves would be circular: the bag you bought already showed your commitment, so including it again inflates the number without adding new signal.
