Percentage Calculator

About Percentage Calculator

Percentage Calculator is the fastest way to handle every percentage calculation you face in daily life. Whether you need to add 18% GST to an invoice, figure out how much your salary went up, split a restaurant bill with a tip, or find out what percentage one number is of another — this app handles it all in one tap, completely offline. Five calculation modes cover every real-world scenario: X% of Y, what percentage is X of Y, percentage difference between two numbers, add a percentage (for GST and markups), and remove a percentage (for tax-exclusive prices). The Tip Calculator tab gives you instant per-person totals with customisable tip rates. The Salary/Change tab computes percentage change with absolute and monthly difference breakdowns. All calculations are saved to your history so you can review and re-use them at any time. Smart insight cards explain what each result means — not just a number, but the full picture.
