Fava Feature Request: Average Value View For Income Statement

This article discusses a feature request for the Fava financial reporting tool, focusing on adding an average value view to the Income Statement. This enhancement would allow users to analyze their financial data more granularly by viewing averages per day, week, or month. This article will delve into the context, example use case, proposed solution, and potential implementation areas within the Fava codebase.

Context: Enhancing Fava's Income Statement with Average Value Views

Fava is a fantastic web-based interface for the Beancount double-entry bookkeeping system. It offers a variety of features for visualizing and analyzing financial data, including the Income Statement. Currently, Fava allows users to change chart types, conversions, and filter data by time, account, or tag. However, one key feature that's missing is the ability to view average values per time unit, such as day, week, or month, for a filtered period. This capability would significantly enhance the analytical power of the Income Statement, allowing for more in-depth insights into spending and income patterns.

The ability to see average values over time is crucial for effective financial analysis. Analyzing financial data isn't just about looking at the total figures; it's about understanding the trends and patterns within those numbers. For instance, knowing the total expenditure for a vacation is helpful, but knowing the average daily cost provides a clearer picture of the trip's financial impact. This level of detail can help users make more informed decisions about their spending habits and budget allocations. Furthermore, average values help in comparing financial performance across different periods, normalizing for variations in the length of those periods. A month with higher expenses might seem alarming, but if the average daily spending is lower than other months, the situation might not be as dire. Therefore, the inclusion of an average value view in Fava's Income Statement would represent a significant step forward in providing users with a more comprehensive and nuanced understanding of their financial data. This enhancement aligns with the core goal of financial management: to gain insights that lead to better financial decisions. By offering a view of average spending and income, Fava would empower users to identify trends, control expenses, and plan for the future more effectively.

Example: Analyzing Holiday Expenses with Average Daily Cost

Consider a specific scenario to illustrate the usefulness of this feature. Imagine you've taken a trip from October 10th to 26th, and all expenses related to this trip are tagged with "2025_Holidays." Currently, Fava can show you the total cost of the trip within the Income Statement, filtered by this tag. However, what if you want to understand the daily spending rate during this vacation? This is where an average value view becomes invaluable. The average daily cost gives a clearer picture of how much the trip truly cost per day, allowing for better budgeting and future trip planning.

Without the average value view, calculating the daily cost requires manual computation, which can be cumbersome and time-consuming, especially for longer periods or multiple trips. Having Fava automatically calculate and display this average significantly streamlines the analysis process. For instance, if the total cost of the 17-day trip (October 10th to 26th) was $3,400, the average daily cost would be $200. This number provides a much more tangible understanding of the trip's financial impact than just the total cost alone. Moreover, this feature isn't limited to just vacation expenses. It can be applied to various financial analyses. For example, one might want to track the average monthly spending on groceries, dining out, or transportation. By seeing these averages, users can identify areas where they might be overspending and make necessary adjustments to their budget. The ability to analyze expenses on a per-unit-time basis also facilitates comparison across different periods. A higher total grocery bill in one month might simply be due to the month having more days, whereas the average daily spending could remain consistent or even lower. This kind of insight is crucial for effective financial management. In essence, adding an average value view to Fava's Income Statement empowers users to move beyond simply tracking total amounts to gaining a deeper understanding of their spending and income patterns over time. This, in turn, enables more informed financial decisions and better overall financial health.
