10Calc Professional Calculator

About this app

10Calc is an adding machine style 10-key calculator for financial and business use cases, particularly accounting. It supports all the functions of business desktop calculators, such as averages, margins, and tax calculations. What makes 10Calc special compared to other Android calculators is its scrolling "tape" journal for displaying all operations. The tape can even be shared with others or printed directly to a local printer. Another great benefit is its portability: 10Calc is always there on your phone!

Note: 10-key calculators work differently from ordinary consumer calculators, so unless you are familiar with 10-key calculators, this is probably not for you.

Ratings and reviews

I’ve been using the 10Calc on my Windows computer for years and it’s been great. But as a realtor, I just love this new Android version! My phone is always with me, so it's really easy to just pull it out and use the calculator on the go - I can easily calculate closing costs for my clients, and the best part is, that I can share the tape with my Buyers and Sellers, a super cool feature. How did I ever work without that?!

I have been searching for a long time for an app that simulates a physical printing 10-key business calculator. The few apps that I found didn't come close to the functionality of a physical calculator...until now! This app is the real deal. Functions include 5/4 rounding, item counting, tax calculations, cost/sell/margin keys, grand total and average. Highly recommend 👍👍

Really big fan of this 10-key. I like it's simplicity and that it functions exactly like my old physical 10-key desk calculator. The ability to print the tape directly from the app or share it so that I can attach it to my reports is a huge help as well. Highly recommend it!
