Discretionary Spending Index (DSI) is a continuous household-based score of 1 to 1000 that ranks households by likely spending capacity and spending behaviors. It enables marketers to rank customers and prospects by estimated spending power.

DSI can be used alone or incorporated into models where consumer spending is a factor. Marketers could use DSI to enhance account management, identify cross-sell opportunities, and provide appropriate offers.

Key Differentiators of DSI
  1. Based on Foundation of Anonymous, Direct-Measured Assets
    • Translates estimated income, factored asset scores derived from IXI’s proprietary financial assets database, and life-stage attributes into an index score that ranks households by estimated spending power
  2. Measures and Ranks Consumer Discretionary Spending Capacity
    • Offers a household scoring system that measures and ranks estimated consumer discretionary spending capacity
    • Helps marketers discriminate between two households that look the same in terms of income and demographics, but likely have considerably different spending power
  3. Household-Level Continuous Score
    • Provides a household-level continuous score ranging from 1 to 1000, with a rating of 1000 representing households likely to have the most spending capacity
    • The higher the DSI score, the higher the likely spending capacity
  4. Can Be Applied Across the Customer Lifecycle
    • Enables financial services and consumer firms to develop appropriate marketing and collections strategies based on a view of discretionary spending capacity
  5. Easy to Apply
    • DSI scores can be appended to any customer or prospect file to identify and target households based on their likely spending capacity
