How do I exclude transactions from my savings rate?

On the Savings page, hover over any transaction and click "Exclude" — it's a one-off exclusion. If you want to always exclude similar transactions, you'll see a toast asking "Always exclude transactions like this?" Click it to create a rule. You can also go to Transaction Rules to manage all your exclusion rules in one place. Excluded transactions still show in your history, they just don't count toward your savings rate or totals.
