Definition
Envelope budgeting is the practice of dividing your money into virtual “envelopes,” one per spending category, and spending only from each envelope’s balance. When an envelope is empty, that category is done for the period — no borrowing from tomorrow.
Key ideas
- One envelope per category: groceries, rent, dining each get their own envelope with its own balance.
- Fill, don’t just track: at the start of a period you “fill” envelopes (often from a main account); the fill method decides what happens to last period’s leftover.
- Running balance, not a monthly sheet: the envelope balance is perpetual — any past or present transaction affects today’s balance, so it’s “keep putting in, keep taking out” rather than “one table per month.”
- Two fill semantics: “Add” rolls last period’s leftover in and adds the new amount; “Set” tops up only to the budgeted amount, ignoring the leftover.
Why it matters in a finance app
Goodbudget is the canonical envelope app: Regular envelopes for routine spending, Annual/Goal envelopes for big once-a-year costs, and the fill choice (Add vs Set) puts rollover control entirely in your hands. If you like the envelope metaphor, don’t mind a few minutes of filling each month, and have few categories, it stays simple; if you have 20+ categories or hate maintaining balances, it gets heavy.
