Big-key calculator: see every figure, M+ M− MR, GT, tax keys & a saved tape.
Business Calculator is a clean, large-key calculator built for shops, offices and anyone who adds up figures all day. No account, no sign-in, nothing to set up. Open it and calculate.
SEE EVERY FIGURE
• The whole calculation stays on screen as you type, for example 2 + 2 + 2 + 2 + 2 + 2 − 6 × 4
• The total updates live at the bottom in large, easy-to-read figures
• Earlier results scroll above like a paper tape, so you can check your work at a glance
• Standard maths rules: × and ÷ before + and −
BUSINESS KEYS
• M+, M−, MR and MC memory keys
• GT (Grand Total) adds up every result — tap to use it, long-press to clear
• TAX+ adds tax and TAX− takes it out of a tax-inclusive price, at the rate you choose (e.g. 18% GST)
• Business-style percent: 500 + 10% = 550, 500 − 10% = 450, 250 × 8% = 20
• 00 key, +/−, backspace
SAVED TAPE
• Every finished calculation is saved with the time
• Tap any result to reuse it
• Copy or share the whole tape as text (to chats, email or notes)
• Swipe to delete one entry, or clear the tape
MADE FOR DAYLIGHT
• High-contrast light theme that stays readable in sunlight
• Large keys that are easy to hit
• Exact decimal maths: 0.1 + 0.2 is exactly 0.3, no rounding surprises
• Choose decimal places (Auto, 0, 2, 3 or 4) and thousands separators
SMALL AND PRIVATE
• No login and no account
• The calculator works fully offline
• Your calculations stay on your phone
Business Calculator is free and supported by ads.
Novità
Now free with ads: a small banner under the keypad and an occasional full-screen ad after you close the tape, never while you calculate. Users in Europe and the UK can manage ad consent in Settings.
