Spending Concentration ​

Spending concentration measures whether your expenses are concentrated in a few categories. Concentration is neither good nor bad by itself — but it is an important lens for understanding the risk and diversity of your spending structure.

Core metrics ​

  • Gini coefficient: a value between 0 and 1. The larger the value, the more your expenses concentrate in a few categories; a small value means expenses are evenly spread
  • Lorenz curve: a curve that intuitively shows "how much spending the top few categories contribute cumulatively"
  • Pareto distribution: identifies "the top categories that contribute most of the spending", for example the top three categories accounting for 70% of total expenses
  • Monthly trend: how concentration changes month by month, to see whether the structure is deteriorating or improving

How to interpret it ​

PatternPossible interpretation
Concentration stays highSpending depends on a few categories, and a swing in one of them will noticeably affect the whole
Concentration is low and stableExpenses are evenly distributed and the structure is fairly robust
Concentration suddenly risesUsually a new large expense — or a new category of them — has appeared; it is worth reviewing

Concentration is a "health indicator", not a KPI

There is no need to tune concentration to some target number. Its value lies in spotting structural change: when concentration fluctuates abnormally, drill down in Income & Expense Insights to see which category caused it.
