Understanding the Basics

- ROI vs. Contribution: We help you see which lever moves the needle more. In the early stages, your monthly contributions from App launches matter most; in the late stages, your ROI percentage becomes the primary driver.
- The ‘Rule of 72’: We automatically calculate how many years it will take to double your money based on your 2026 performance metrics, giving you a quick benchmark for your Business Growth.

Frequently Asked Questions
1. Is the S&P 500 at 7,501 “overvalued” for a new investment? While the market hit a record this week, earnings in the AI and tech sectors have grown significantly. Most 2026 analysts suggest a “Moderate” projection of 7%–9% for the next five years is more sustainable than the recent double-digit surges.
2. Should I include my “Trump Account” in my ROI math? Yes. These new accounts (with a $5,000 annual limit) offer tax-free growth. Contributions made this month are high-ROI moves for parents due to the $1,000 federal seed grant for children born 2025–2028.
3. How does the 3.8% inflation affect my ROI? It raises your “hurdle rate.” You cannot claim a successful investment if your return is below the inflation rate. In May 2026, “Cash is Trash” for growth purposes because it barely breaks even after taxes and inflation.
