Our Methodology

1. Defining the Core Variables

Every LifeTradeoffs tool begins by identifying the "Unrecoverable Costs" of a decision. While standard calculators focus on monthly cash flow, our methodology accounts for the deeper economic impacts:

• Opportunity Cost: We factor in what your capital could have earned if invested in a diversified portfolio (e.g., S&P 500) instead of a specific asset.
• Depreciation Curves: For transportation and hardware, we utilize historical data to project asset value decay over time.
• Inflation Hedging: We analyze how fixed-rate debt compares to rising rental or service costs over a 10-year horizon.

2. Transparent Input Logic

We believe the user knows their situation best. Our tools serve as a computational "sandbox" where you can test different financial environments.

• Scenario Modeling: Adjust rates, taxes, and maintenance fees to see "Best Case" vs "Worst Case" outcomes.
• Client-Side Privacy: Your data never touches our servers. The logic is executed locally in your browser, ensuring total privacy for your financial inputs.

3. Quantitative Comparison

Instead of a simple "Yes" or "No," we provide a side-by-side comparative analysis of two different paths (e.g., Job A vs. Job B). This reveals:

• Effective Hourly Rate: The true value of your time after commuting, taxes, and work-related expenses.
• Net Present Value (NPV): The total value of a financial path in today’s dollars, allowing for a fair comparison across long timelines.

4. Decision Clarity, Not Persuasion

Our goal is to eliminate "Analysis Paralysis." By moving the decision from the emotional brain to the logical brain, we provide the clarity needed to act. We do not use "gamification" or nudge you toward specific high-cost financial products.
