Questions people ask
Why compound the losses instead of subtracting?
Each loss is a percentage of the balance that is left, so the dollar amount shrinks as the account does.
Limitations
Every result here is arithmetic on the numbers you enter. It carries no view on any specific security, assumes returns are steady when real returns are not, and ignores taxes, slippage and commissions. Use it to size and sanity-check, not to forecast.
