Stock Break-Even Calculator
Down on a stock? Find the exact price — and the required % gain — you need to fully recover your loss. Supports multiple purchase lots and optional broker commissions.
Bought at different prices? Add each purchase separately. The calculator finds the single price that fully recovers the combined position.

// 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.
