Frequently Asked Questions
What is the difference between a "Calculator" and an "Engine"?
Most calculators are static—they perform one simple math function. Our "Engines" are dynamic systems designed to model variables over decades. They adjust for inflation, varying rates of return, and cross-tool data syncing to give you a cohesive strategic outlook rather than a single number.
How accurate are the math models used here?
Our algorithms utilize standard professional financial compounding and amortization formulas. We use annual compounding intervals and provide real-world inflation modeling to ensure your wealth forecasts remain realistic in the context of long-term economic shifts.
Is my sensitive financial data really private?
Yes. Quiet Money is unique because we do not have a server-side database. Your information is stored only in your own browser's secure "Local Storage." This means your data never leaves your device and cannot be accessed by anyone else.
Do I need a user account to save my profile?
No. We don't want your email or personal identifiers. The "Shared Brain" protocol remembers your profile as you move between our tools automatically, allowing for a seamless planning experience without any invasive sign-up requirements.
