Envelope Budgeting Example — beancount.io
A Beancount ledger demonstrating envelope (zero-based) budgeting: giving every dollar a job before it is spent, and seeing immediately when a category runs dry.
The method rests on one idea — envelopes are equity, not assets. The money is already in the bank; budgeting only decides what it is promised to. So an allocation moves value between equity subaccounts and never touches Assets, which is why the overlay can never disturb your bank reconciliation.
The ledger also declares matching native custom "budget" targets for each expense account. The equity postings provide rollover envelope balances; the custom directives power beancount.io's Budget report and its budget-versus-actual charts. They are complementary views of the same monthly plan.
Quick Start

The one thing to copy
Spending is four postings, readable as two independent pairs:
2026-01-08 * "Whole Foods" "Weekly shop"
Assets:Bank:Checking -128.44 USD ; what your bank sees
Expenses:Groceries 128.44 USD
Equity:Budget:Groceries -128.44 USD ; what your budget sees
Equity:Budget:Unallocated 128.44 USDEach pair balances on its own, so the budget overlay is always safe to add, remove, or ignore.
