fava_miler

Airline miles and rewards points: expiration and value reporting for Fava/Beancount (Personal finance software).

Introduction

Airline miles and rewards points typically expire after a period of inactivity. They also can be viewed as having a value in a currency of your choice. If you track airline mile transactions in Beancount, this simple plugin reports on the value of miles and their expiry date. This is particularly useful if you have miles/points on many airlines or businesses.

Installation

pip install fava-miler

Configuring your beancount source

• Define your operating_currency
• Declare the currency for each of your airline miles
• Add expiry-months and points-value metadata to your commodity declaration
  • Any negative value for expiry-months signifies that this commodity never expires

This should get the reporter working. Example:

option "operating_currency" "USD"
1990-01-01 commodity MILESAIRALD
    expiry-months: 24
    points-value: 0.015 USD

2000-01-01 open Assets:Miles:AirAldorra MILESAIRALD
2000-01-01 open Income:Misc

2010-01-01 * "Credit card miles"
        Assets:Miles:AirAldorra 100 MILESAIRALD
        Income:Misc
