Frequently Asked Questions

Get detailed answers about the platform and our underlying mathematics.

Are the calculation results completely accurate?

Yes. RealTools utilizes standard financial equations recommended by professional institutions. However, they evaluate a steady compound trajectory; real-world market volatility, inflation adjustments, and tax rates will cause final assets to vary.

Do you charge any hidden fees or require signups?

No. RealTools is 100% free with no registrations, email marketing capture, subscriptions, or hidden walls. It exists simply as a public investment service.

How does RealTools protect my financial privacy?

Our entire application architecture is built using client-side JavaScript. This means all formulas compile, evaluate, and output variables locally within your own browser engine. We never transmit your inputs to our servers.
