I built a calculator that compares brokerage platforms in annual monetary value instead of star ratings. Looking for honest feedback
brokerage comparison, monetary value, calculator, financial transparency, user-specific modeling
Developer built Brokerage Value Index — a free, interactive calculator comparing 7 major brokerages by estimated annual dollar value for individual users. Calculator incorporates cash yields, card rewards, IRA matches, fees, and acquisition offers — all adjustable via user inputs. Explicitly disclaims universal 'best' rankings and invites community feedback to improve methodology and assumptions.
Spin Analysis: methodological humility framing
Emphasizes transparency and iterative development while minimizing the absence of verification, benchmarking, or institutional oversight; avoids asserting accuracy or reliability.
Independent, user-centric, anti-opaque fintech utility
A developer built a free calculator that estimates the annual dollar value of using different brokerage platforms based on user inputs.
No disclosure of data sources, update cadence, or error margins; No mention of regulatory compliance considerations (e.g., SEC/FINRA guidance on comparative tools); No discussion of edge cases like account closures, tiered pricing, or cross-platform bundling effects
The story redirects attention toward process, intent, scale, mission, or future benefits instead of unresolved concerns. Watch for loaded terms such as measurable approach, transparent dollar estimates, subjective overall score. The distribution reads as promotional distribution. A pressure point: No disclosure of data sources, update cadence, or error margins.
The Brokerage Value Index provides transparent dollar estimates instead of subjective overall scores.
The goal is to provide an alternative way to compare platforms using transparent dollar estimates instead of a subjective overall score.
