fava-envelope-airmail 2026.2.9

Envelope budgeting for Fava/Beancount with stats, scheduled transactions, and color-coded UI

fava-envelope-airmail

A fork of memst/fava-envelope (itself a fork of polarmutex/fava-envelope) that adds several enhancements for envelope budgeting in Fava/Beancount.

I'm open to merging these changes upstream, but the original repos haven't seen much merge activity lately, so I decided to publish this fork separately in case anyone else finds the enhancements useful.

What's New in This Fork

Budget Statistics Page

A new Stats view accessible from the budget page header that provides:

• Overall summary cards: total periods tracked, total/average income, total budgeted vs. spent, and overall budget adherence rate
• Per-envelope statistics: period counts, under/over budget breakdowns, adherence percentages, average activity, and standard deviation
• Categorization of envelopes into "Well-Managed" (>80% adherence) and "Needs Attention" (<50% adherence)
• Color-coded stats table rows by adherence rate

Scheduled Transaction Tracking

• Transactions flagged with X (e.g., upcoming/scheduled bills) are now tracked per envelope
• A badge appears next to envelope names showing the count and total of scheduled transactions for that month (e.g., 2X)

Account Ignore Directive

A new ignore directive to exclude accounts from envelope budgeting (e.g., taxes, 401k contributions). Ignored accounts are treated as income deductions rather than being completely skipped:

2020-01-01 custom "envelope" "ignore" "Expenses:Taxes:.*"

Color-Coded Budget Table

• Envelope rows are color-coded based on account type and available balance:
  • Expenses: green (under budget), yellow (exactly zero), red (overspent)
  • Assets: blue (negative/receivable), green (positive)
  • Liabilities: treated like expenses
• Income "To be budgeted" row is color-coded: green (surplus), red (deficit), yellow (zero)
• Individual amounts within rows show positive/negative coloring
• Full dark mode support

Other Improvements

• Envelopes are now sorted alphabetically
• Default month view is the current month (instead of the last available month)
• Redundant "Amount" column is hidden when only one currency is configured
• Rolled-over allowance column shows positive/negative coloring

Inherited Features (from memst/fava-envelope)

• No pandas dependency (faster)
• Cached envelope results until source files change
• Multi-currency support
• Simplified budgeting table
• Proper ACCOUNT types in directive parsing
• Advanced directives: allocate fill, income override, allow negative rollover, include starting balance, repeat-until metadata

Please check the changelog for full details.

pip install fava-envelope-airmail

From Source

git clone https://github.com/stenius/fava-envelope-airmail.git

Usage

Load the Extension

Add this to your beancount journal, and start fava as normal:

2000-01-01 custom "fava-extension" "fava_envelope" "{}"

You should now see 'Envelope' in your fava sidebar. You must set up a budget (see below), or Fava will report a 404 error.

Setting Up a Budget

Start date

2020-01-01 custom "envelope" "start date" "2020-01"

Budget months ahead

Show future months for budgeting ahead (default is 0):

2020-01-01 custom "envelope" "months ahead" "2"

Budget accounts

Specify the Assets and Liabilities included in your budget (supports regex):

2020-01-01 custom "envelope" "budget account" "Assets:Checking"
2020-01-01 custom "envelope" "budget account" "Liabilities:Credit-Cards:.*"

Mappings

Map sub-accounts to a parent envelope:

2020-01-01 custom "envelope" "mapping" "Expenses:Food:.*" Expenses:Food

Ignore accounts

Exclude accounts from budgeting (e.g., taxes deducted from paychecks):

2020-01-01 custom "envelope" "ignore" "Expenses:Taxes:.*"

Allocate money to an envelope

2020-01-31 custom "envelope" "allocate" Expenses:Food 100.00 USD

Operating currency

The extension reads the operating currency from beancount options (defaults to USD):

option "operating_currency" "EUR"
