Borrowing to invest in an asset will not simply multiply your returns. It is more accurate to say that leverage amplifies the difference between the returns on the asset and the cost of borrowing. This post was originally published on 18-Dec-2016. I have since made an interactive leveraged returns calculator . Short Form Calculation Return on Equity = Interest Rate Differential x Debt to Equity Multiple + Asset's Return For example: 8:1 Debt to Equity at 4% debt interest with an asset return of 5%: 1 x 8/1 + 5 = 13% Visualisation looks a little something like this: ROE Alpha (Y-axis) by Return-Borrowing Differential (Z-axis) by Borrowing (X-axis)
