Understanding the Basics
- The ROI Formula: We use the standard metric:$$((\text{Final Value} – \text{Initial Cost}) / \text{Initial Cost}) \times 100$$. This provides a universal percentage that allows you to compare a App launch against a traditional stock market investment.
- Anticipated vs. Actual: This tool allows you to run “What-If” scenarios for upcoming tools. Use “Anticipated ROI” to prioritize your development roadmap and “Actual ROI” to audit your past performance.
- Annualization: A 50% return over 5 years is different from a 50% return in 6 months. We calculate the Annualized ROI to give you a true sense of your wealth-building speed.

Frequently Asked Questions
1. How does the “OBBBA” affect my net worth projections?
The One Big Beautiful Bill Act (OBBBA), signed in July 2025, made several key tax cuts permanent. For your 2026 projection, this means you can rely on the 20% pass-through deduction for side-hustle income and lower individual tax brackets indefinitely. It also significantly increased the SALT deduction cap to $40,000, which likely gave your liquid assets a “one-time” boost this month via your 2025 tax refund.
2. Why is “Real Growth” so much lower than my account balance growth?
As of May 2026, headline inflation has accelerated to 3.8%, largely due to the 17.9% spike in energy costs this spring. While your S&P 500 balance may be up 12%, you have to subtract that 3.8% to see your “Real” wealth. In May 2026, if your assets aren’t growing by at least 4% annually, you are technically losing purchasing power.
3. What is the “July 1st Student Loan Shift”?
On July 1, 2026, the new Repayment Assistance Plan (RAP) becomes the primary income-driven repayment option. If you have federal student loans, your monthly liability may decrease to 1%–10% of your AGI. The calculator factors this “Found Liquidity” as an asset multiplier, as that saved cash can now be redirected into compounding investments.
