The Johnsons: Unlocking an Extra $15,000 Savings with MPS Analysis

Executive Summary

This case study examines how "The Johnsons," a dual-income household with significant financial commitments, leveraged a fintech tool, the Marginal Propensity to Save (MPS) Calculator, to unlock an additional $15,000 in annual savings. The Johnsons, earning $450,000 annually and holding $2.1 million in retirement savings, felt they could be doing more to optimize their savings, particularly given the looming expenses of funding college for three children and maintaining their desired lifestyle. They lacked a data-driven understanding of how incremental income changes impacted their savings behavior. By using the MPS Calculator to analyze their historical financial data, we identified a significant gap between their income and savings potential. A targeted strategy, informed by the MPS analysis and enhanced by debt-to-asset ratio insights, enabled them to increase their savings rate and project an additional $67,500 in savings over five years, bolstering their college funds and retirement readiness. This case demonstrates the power of personalized financial analysis in driving impactful savings outcomes.

The Problem

The Johnsons, a married couple with three children, represent a common scenario for high-income earners in the United States. Both are professionals with demanding careers, earning a combined $450,000 annually. They have diligently saved for retirement, accumulating a portfolio valued at $2.1 million. However, they faced a growing concern: were they truly maximizing their savings potential given their income and the significant financial demands of their growing family, including funding three college educations?

While comfortable, the Johnsons felt constrained. They adhered to a general savings plan based on traditional financial advice (e.g., saving 15% of their income). However, they lacked the granularity and data-driven insights to understand if this generic advice truly applied to their unique circumstances. Their specific concerns included:

• College Funding Uncertainty: The rising cost of higher education loomed large. They were unsure if their current college savings trajectory would meet their goals without significantly impacting their retirement savings. Traditional college savings calculators offered limited value because they did not account for nuances in their specific spending habits.
• Inefficient Savings Rate: They suspected that their current savings rate, while seemingly adequate, was not optimized for their income level. They questioned if they were leaving money on the table, missing opportunities to accelerate their financial goals. They felt that they should be saving more given their income, but did not know where to look.
• Lack of Visibility into Marginal Savings: The Johnsons lacked a clear understanding of their Marginal Propensity to Save (MPS). They were unsure how incremental increases in their income translated into actual savings. Did a raise simply result in more spending, or were they effectively capturing a portion of that increase to bolster their savings?
• Impact of Lifestyle Inflation: As their income grew over the years, so did their lifestyle. They were concerned that they were unknowingly allowing lifestyle inflation to erode their savings potential. They lacked a tool to quantify the impact of lifestyle spending on their ability to save.
• Complex Financial Picture: With multiple investment accounts, college savings plans (529s), and varying debt obligations, the Johnsons' financial picture was complex and difficult to manage holistically. They needed a solution to simplify their financial planning and provide a clear path toward their goals.

The traditional financial planning tools and general rules of thumb were insufficient to address the Johnsons' specific needs. They required a sophisticated, data-driven approach to understand their savings behavior and unlock their full savings potential. The lack of such a tool was preventing them from achieving their financial goals with greater confidence. This problem highlights a common need among high-income earners: the demand for personalized financial analysis that goes beyond generic advice and delivers actionable insights.

Solution Architecture

To address the Johnsons' challenges, we employed the MPS Calculator and integrated its findings into a comprehensive financial analysis, augmented by a Debt-to-Asset Ratio calculator. The solution architecture comprised the following key elements:

1. Data Collection: We gathered three years of historical financial data from the Johnsons, including:

   • Tax returns: Provided detailed income information and deductions.
   • Investment statements: Provided data on retirement account balances, contributions, and investment performance.
   • Bank statements: While not used for the MPS calculation directly, these helped validate assumptions about spending habits and identify potential areas for optimization.

2. MPS Calculator: The core of the solution. This tool analyzed the relationship between the Johnsons' income and savings over the past three years to determine their Marginal Propensity to Save (MPS). The MPS is a key economic concept that measures the proportion of an increase in income that is saved rather than spent.

   • Algorithm: The MPS Calculator employs a regression analysis to determine the statistical relationship between income and savings. It controls for factors like inflation and significant one-time expenses to ensure accuracy.
   • Output: The calculator provided a precise MPS value (in this case, 0.20), indicating that the Johnsons were saving only $0.20 of every additional dollar earned.

3. Debt-to-Asset Ratio Calculator: While the MPS Calculator focused on savings behavior, the Debt-to-Asset Ratio calculator provided a broader view of the Johnsons' financial health. This calculator assessed their overall debt burden relative to their assets.

   • Purpose: To identify opportunities to reallocate assets or reduce debt to further optimize their financial position.
   • Output: The calculator provided a ratio indicating their level of financial leverage, which was then compared to industry benchmarks and tailored to their risk tolerance.

4. Financial Planning Software Integration: The outputs from both calculators were seamlessly integrated into financial planning software, allowing us to model different scenarios and project the long-term impact of changes in their savings behavior.

5. Scenario Planning & Optimization: Using the integrated data, we conducted scenario planning to explore the impact of increasing their savings rate. We modeled scenarios with a 1%, 2%, and 3% increase in their savings rate to demonstrate the potential impact on their college funds and retirement savings.

6. Personalized Financial Plan: Finally, we developed a personalized financial plan that outlined specific actions the Johnsons could take to increase their savings rate, optimize their asset allocation, and achieve their financial goals.

The architecture emphasized data-driven decision-making, personalized insights, and seamless integration with existing financial planning tools. This approach allowed us to provide the Johnsons with a clear, actionable plan to improve their financial outlook. This represents an evolution of traditional financial planning, leveraging fintech to go deeper than ever before.
