Executive summary For businesses, the ability to predict individual consumer spend amount within a specific time frame is essential. It impacts their marketing strategies across the customer life cycle, particularly in the areas of customer acquisition and account management. But, their ability to understand spending preferences is also a key factor in developing customer loyalty.
To provide that wider view of individual consumer credit behaviors, Equifax Dimensions™ was developed. The solution delivers unique consumer insights around credit usage and payment behavior signals transpiring over 24 months of history. By leveraging aggregated time series account-level consumer credit attributes, Equifax Dimensions can help businesses identify consumer behavior patterns and trends by industry and account type and use that data to better segment and target consumers with more meaningful offers.
Proving the value of Equifax Dimensions, a data-driven comparison study within this document reveals how the solution can help businesses drive stronger, more profitable marketing and sales strategies by more accurately targeting high-spend consumers in the market. The study shows how Equifax Dimensions can:
• More powerfully rank spend amounts compared to using traditional credit attributes alone
• More efficiently separate high-spenders from low-spenders
• Help improve revenue opportunity throughout a large portfolio
Based on the sample population outlined in the study, the results show how using Equifax Dimensions can help generate an estimated $111 million in increased spending and $4.2 million in potential new revenue within the top 30% percent of the population, providing businesses with a fresh strategy for increasing revenue while also reducing marketing costs.

Know more about consumers by understanding their past behavior
Often, the best predictor of future behavior is past behavior. It was on this premise that Equifax Dimensions was developed. As a complement to basic tools such as consumer reports, which provide a “snapshot” of credit activity at one specific point in time, Equifax Dimensions helps reveal consumer credit trends that measure the general direction in which the data is developing, such as increasing or decreasing spend levels.
Specifically, Equifax Dimensions provides 500 consumer attributes built from 24 months of account-level data that complies with Fair Credit Reporting Act guidelines. In practical applications, the trended data provided by Equifax Dimensions can help businesses identify:
• Propensity to open new accounts within a period of time
• Accounts more likely to be active
• Likelihood of balance transfer within a period of time
• Best candidates for line increases and likelihood to stay current
• Capacity to take on more debt without becoming past due
• How credit is used over an extended period of time
• Past credit performance and behaviors
• Credit stress and risk before delinquency and charge-off
• Accounts best suited for efficient collections and recovery efforts
The solution includes flexible controls that allow users to set unique consumer risk levels, behaviors and characteristics, so businesses can more accurately identify and address specific behaviors that align with their business model. Likewise, the solution attributes are available both online for real-time decisioning, and offline for custom analytics and account management functions.
Trended or Time-Series Data
Trended, historical, longitudinal or time-
series information captures the trends
within a data set for a specific period
of time. A sequence of data points is
typically measured at successive points
in time spaced at uniform time intervals.
Time-series data can be analyzed to
extract meaningful statistics and help
predict future values based on previously
observed values.
When measuring trended data within
a consumer credit profile, analysis on
direction, velocity, tipping points and
magnitude of changes within the profile
can deliver valuable information on credit
behavior such as spending and payment
patterns.

Optimize business performance by “knowing more”
Study shows Equifax Dimensions significantly expands predictive insight To demonstrate how Equifax Dimensions can better predict consumer spend, this study used a two-stage testing methodology to compare the time-series attributes within Equifax Dimensions to traditional credit attributes, which use static data. The first step calculated spend on an account level first and then aggregated it to the consumer level. The second step distinguished high spend versus low spend. Observation status was defined as follows:
MethodologyTwo predictive models (logistic regression models) were built to forecast high spend:
• Champion model only utilized standard credit attributes, a set of attributes providing effective solutions for risk and profitability goals.
• Challenger model utilized standard credit attributes plus Equifax Dimensions attributes. Incremental lift is measured on statistical performance, based on a Kolmogorov-Smirnov (KS) test,1 and 10 percent, 20 percent, and 30 percent target capture rates2.
Result DetailsMore powerfully ranked spend amounts compared to using traditional credit attributes alone
Capturing consumer spend is a top priority for lenders. To better illustrate the capabilities of Equifax Dimensions attributes, Equifax used the sample population to further examine the relationship between score values and average “Total Spend Value within 12 Months.”
Data A random 1% sample of the Equifax National Credit Database
Exclusion Criteria - Deceased consumer- Consumer with bankruptcy- Consumer with fraud- Not a tradeline
Industry Revolving accounts
Use Case Spend: total spend amount on revolving accounts within 12 months is defined by using a combination of balance and payment information
Spend was modeled as binary target variable: high spend/low spend created at the median (around $500)
1 The Kolmogorov-Smirnov (KS) statistic is the measure of the maximum distance (greatest separation) between the cumulative % of high spend (goods) and the cumulative % of low spend (bads) across all score ranges. It represents the model's ability to differentiate "goods" from "bads" in the sample. Higher values indicate better overall separation and a stronger model.
2 10% capture rate: what percent of “bads” are captured within the 10% highest scores. In this comparison study, it means the rate to capture “high-spend” consumers. Similar for 20% and 30% capture rate.
Result OverviewBased on the sample population studied, adding Equifax Dimensions in the Challenger model captured more high-spenders and generated more spending in top deciles compared to the Champion model, capturing about 1,800 more high-spenders and generating about $38 million more spend and $1.4 million in potential new revenue in the top decile.

Figure 1 demonstrates that credit attributes and Equifax Dimensions used together can powerfully rank order the spend amount—the higher the score, the higher the spend.
More efficient separation of high-spenders from low-spendersFigure 2 demonstrates how Equifax Dimensions more efficiently separates high-spenders from low-spenders compared to using credit attributes alone. After adding Dimensions attributes, the percent of high-spenders captured in the top three deciles (or top 30%) of scores is higher in the Challenger model, illustrating the value of Dimensions attributes to capture high-spenders.

Improved revenue opportunity throughout a large portfolioTo optimize offers, terms and promotions, businesses need as much reliable insight as possible into how much consumers are spending. Figure 3 shows that using credit attributes alone in the Champion model provided strong model performance with a KS of 43.77. However, adding Equifax Dimensions further improved the model's predictive performance, with the Challenger model hitting a KS of 46.78 - a 7 percent lift over the Champion model.
More importantly, the target capture rates across the top three score deciles in the sample population improved by more than 4 percent, demonstrating that Equifax Dimensions can deliver deeper insight on more consumers.
Figure 4 shows the percent of increased spend amount for all score ranges after adding Equifax Dimensions attributes to the Champion model. Equifax Dimensions attributes effectively push high-spend consumers to the top score ranges, as spend amount is increased by 17 percent, 11 percent and 6 percent for the top three score deciles.

Considering Figures 3 and 4 together, it shows how Equifax Dimensions can help businesses target high-spend consumers more accurately in the market by putting a spend-amount increase analysis into model comparison results. After adding Equifax Dimensions attributes, the top score decile's target capture rate increased by 0.66 percent, but spend amount increased by 17 percent compared with the “Credit-Attributes-Only” model.
The same pattern can be found on the top 20 percent and 30 percent deciles with a diminishing trend. This indicates that Equifax Dimensions can not only push high-spend consumers to the top score deciles, but it can also suppress the low-spender rate, thus helping to increase the revenue opportunity.

To demonstrate the increased number of high-spenders and total spend in top deciles captured by the Challenger model over the Champion model, Figure 5 presents a detailed example scenario based on a sample portfolio of 1 million consumers.
Adding Equifax Dimensions helps capture more high-spenders in top deciles, capturing about 1,800 more high-spenders and generating about 38 million dollars more spend in the top decile in the sample portfolio. This strategy helps increase the revenue opportunity throughout a portfolio, while also reducing the long-term costs to identify and market to those high-spenders.

The sample portfolio was also used to gauge potential incremental interest and transaction fees. Using Equifax Dimensions to identify more consumers that spend more over a 12-month period can result in incremental revenue of up to $1.4 million in the top 10% of scored consumers. This example assumes no other fees besides APR and transaction fees, and that half of the new consumers are revolvers making only the minimum payment.
