The Maul MTL 800 is a desktop calculator for commercial use, with an extra large housing of 140mm x 190mm (LxW), large keys and a large LCD display. The calculator has functions such as tax calculation (price with/without tax key), profit margin calculation, profit-cost-margin calculation and a percent key. The Expense and Profit Cost Margin keys have a signal colour, making them easier to find. The calculator is equipped with a rounded and therefore more legible 2-line LCD display. The calculation method is also displayed here. The MTL 800 is battery and solar powered. If you leave the calculator on without using it, it will automatically turn off. The keys are made of sturdy plastic and easy to clean.
