Marcus Lemonis Margin Calculator is a free Android application developed by Renowne LLC in the category of Business & Productivity, specifically for Finance. The app is designed to calculate cost, margin/markup, price, and commission, making it an essential tool for business owners. The app is easy to use, and you can input two known variables to get an accurate answer quickly.

The app comes with six functional calculators, including Cost, Margin/Markup, Price, Commission, Break-Even, and Standard Calculator. Additionally, you can toggle between margin and markup easily, and the app automatically imports results from a built-in calculator into individual calculation fields. The roll calculation function allows you to add multiple margin and markups to price, making it easy to get accurate results.

As seen on episodes of CNBC's The Profit, Marcus Lemonis personally uses this app for his calculations. With this simple yet powerful business tool, you can achieve your business goals by "Knowing Your Numbers!" The app is a great addition to any business owner's toolkit.
