Ten losses at 1%, 2% and 5%: the money math
Use one formula for every row: ending balance = starting balance × (1 − risk fraction)^loss count. Because each loss is a percentage of the current balance, the dollar loss shrinks a little as the account shrinks, so ten 1% losses cost $95.62, not $100.
Recovery is the part people underestimate: recovery = drawdown ÷ ending balance. A 9.56% drawdown needs about 10.57% to repair. A 40.13% drawdown needs about 67.02%, because the gain is earned on a smaller balance. Losing streaks happen in any record of trades, so pick the percentage you could live with through one.
