Change one assumption
Test a cost, a loss or a planned position. These examples use hypothetical numbers, not live prices or return forecasts.
Compare the same starting balance and gross return, changing only the annual fee.
Model: starting amount × (1 + gross return − annual fee)years. No contributions, taxes, inflation or changing returns. Rounded to the nearest dollar.
Add contributions and stress scenarios →A percentage recovery starts from a smaller balance. See the gain needed to return to the starting point.
Model: loss ÷ (100 − loss) × 100. The result is arithmetic, not the chance of recovering or the time it will take. An investment may never recover.
Read the risk management guide →For a hypothetical long stock position, divide the remaining risk budget by the distance to the stop.
Model: floor((budget − costs) ÷ (entry − stop)). This simplified example excludes leverage, liquidity and account buying power. A stop is not a guaranteed execution price.

How to read this comparison: SPY and QQQ are ETF proxies, not index levels. Closing-price changes exclude reinvested dividends and costs. A stock moving differently from an ETF is an observation, not evidence of a cause or a trading opportunity.
