Please Note: Needed % gain to restore loss = [1 / (1 – % Loss)] – 1 For example, the needed gain to restore a 10% loss can be expressed as: [1 / (1 – .10)] – 1 = .1111 or 11.11% Thus, the needed gain to restore the 10% loss is 11.11%. As the loss gets bigger, the needed gain to restore the loss increases at an increasing rate.
