You check your balance before buying groceries, but the number does not tell you how much is already meant for something else. An envelope budget gives those intentions names. Each envelope represents a category, and its remaining amount shows what you have assigned to that purpose.
You can use physical envelopes, a notebook, or a digital tool. The useful habit is the same: assign an amount, record what you spend, and check what remains. This guide explains how to start an envelope budget with a small, manageable first version. The examples are fictional bookkeeping exercises, not promises about how much you will save.
