Moffsoft Calculator has a simple, easy-to-use interface that allows a user of any level to start crunching numbers immediately, but don't be deceived by its simple appearance. The power that lies within is only a click or two away. In addition to the printable and savable calculator tape, you'll discover powerful financial functions that include the time value of money, amortization schedules, bonds, interest rate conversions, cash flow, and depreciation. You'll also find over 100 unit conversions in categories such as length, volume, weight, area, speed, time, temperature, currency, and data storage. Moffsoft Calculator also has a variety of date and time calculations that will determine the day of the week, the week of the year, the difference between two dates, and much more. Use the product pricing functionality to calculate cost of goods sold, profit margin, retail sales price, and gross profit. You can also markup and markdown a product's price to quickly assess the impact on your profit.

Since Moffsoft Calculator was designed with the user in mind, you can customize virtually every aspect of the user interface. You can disable or hide unused buttons, and change the color and font of almost everything. Select one of our color schemes or create and save your own. You can even export your favorite schemes to share with a friend. The main calculator window can also be sized. Make it very small to conserve desktop space, or make it very large for readability. Make it any size you want and Moffsoft Calculator will remember the size and position next time you use it.

Other user options include floating point and fixed decimals, item count, multiple memory values, constants, system tray icon, always on top, feedback with sound, run on startup, and much more. You can also select the calculator input logic that's most natural for you. Algebraic input works like a standard hand-held calculator, while adding machine input functions similar to a desktop 10-key.
