Business Calculator is a free utility and tool application available on Android devices, designed by CO. LTD. TAS. The calculator is specifically created to provide a comprehensive set of features that cater to business needs. One of the major features of this calculator is the support for "profit and loss" necessary for estimate creation. You can enter two values of cost, selling price, and profit, and it will automatically calculate the remaining value.

Apart from this, the calculator also supports memory calculation, tax inclusion/exclusion display, square root, and percentage calculation. The history of all calculation formulas, including profit and loss, can also be viewed. The calculator offers a wide range of settable items, including display mode, the number of decimal places to display, tax rate, and rounding. You can select from two key layouts, and vibration and sleep mode can be turned on or off.

The calculator also allows you to press the "MRC" key once to read from memory and twice to clear memory. Similarly, pressing the "C" key once clears only the current state, and pressing it twice will clear all. Business Calculator is an excellent tool for business owners, accountants, and anyone who needs a comprehensive calculator to perform complex calculations.
