About the Loss Percentage calculator

Calculate the percentage you have lost on an investment or purchase, and the gain needed to recover.

How to use the Loss Percentage calculator

  1. Enter the Initial Basis (Cost) and the Current Valuation.
  2. Press the button to see the loss percentage, the amount lost and the gain required to break even.

Formula and method

Loss % = (Cost − Current value) ÷ Cost × 100. Gain needed to recover: Loss ÷ Current value × 100.

Worked example

Losing 25% (for example $10,000 falling to $7,500) needs a gain of 33.3% to get back to the start.

Tips

  • Losses are asymmetric: the bigger the loss, the larger the gain needed.

Frequently asked questions

Why do I need a bigger percentage gain to recover?
