The Mathematics of Recovery

// Why Recovery Takes More %

A 50% loss requires a 100% gain to recover. Losses and gains are asymmetric — you lose from a larger base, but you gain from the smaller reduced base.

// Averaging Down

Buying more shares at a lower price reduces your average cost basis, bringing the break-even price closer to the current market price.

// Commission Impact

Broker fees add to your cost basis. On small positions they can meaningfully shift your break-even price — especially with round-trip (buy + sell) costs.

// Unrealised vs Realised

This calculator shows unrealised loss — what you'd lose if you sold now. The loss only becomes real (and potentially tax-deductible) once you sell.
