Tip, tax, discount and % change in one tap. Big keys, no ads, works offline.
Percentage Calculator by Atlas does percentages and nothing else. No ads, no account, nothing to buy.
FOUR SCREENS, ONE JOB EACH
• % of: what is 15% of 80? (12)
• What %: 45 is what percent of 60? (75%)
• % change: from 1,250 to 1,100 is down 12%, with the difference shown
• + / − %: add sales tax, a tip or a markup, or take off a discount. 49.99 + 8.25% = 54.11; 80 − 25% = 60
EASY TO READ
• Large numbers and a big keypad
• The answer updates as you type, with the sum written out in plain words
• ± key for negative numbers, Next to jump to the other box
• High-contrast dark screen
• Remembers what you last typed on each screen
UNDER MORE
• Price before tax or discount: find the original price from a total (108.25 with 8.25% tax was 100)
• Margin and markup: selling price from your cost and the margin you want
• Copy the result
HONEST MATH
• Clear messages instead of wrong answers when a sum would divide by zero (for example a % change from 0)
• Percent change uses the size of the starting value, so the sign always shows whether the number went up or down, even with negative numbers
• Answers show up to 4 decimal places; money screens round to 2
