Terms and financial limitations

Common Investor is a research calculator, not personalized investment advice, a broker, or a promise of investment performance. You choose the assumptions. Modeled returns and benchmark comparisons are scenarios, not forecasts or historical index results.

Verify the source data

Quotes and fundamentals come from third parties. Availability, freshness, reporting periods, share-class coverage, earnings definitions and provider multiples may differ. Prices are not guaranteed real-time. Review the source and timestamps shown, verify figures against company filings, and do not rely on this tool alone for trading or investment decisions.

Current functionality

The website implements the disclosed P/E valuation method. Conditional P/S valuation is unavailable. News, Insights history and unfinished Compare features are not represented as completed functionality. Saved historical results retain their recorded version; explicitly creating an updated calculation produces a separate calculation.

Accounts and service

Use your own Google account and do not access another user's research, misuse the public API or attempt to bypass security. Introductory Premium currently has no billing requirement or automatic expiration. No payment or paid subscription is created by registration. Free hosting/provider quotas can interrupt service.

Keep a separate copy of important research. Library deletion is recoverable for 30 days; account-deletion requests and provider retention limits are described in the privacy notice. Contact support for help or account requests.
