AI Stock Picker ROI Calculator

How to use this calculator

Enter portfolio size, annual tool cost, AI-return assumption, and benchmark-return assumption. The tool estimates net AI outcome, benchmark outcome, and relative difference.

When this calculator is useful

• Evaluating AI investing tool claims
• Seeing when subscription cost matters
• Comparing return claims to a simple benchmark

Important limitations

This does not verify performance. AI tool claims may be unaudited, backtested, cherry-picked, or unsuitable for your risk tolerance.

For best results, run at least three cases: a conservative case, a middle case, and a stretch case. If a small change in inputs creates a big change in the answer, that is a sign the decision may be sensitive to rates, fees, timing, or market performance.
