The Universal Percentage Calculator
Whether you're shopping sales, splitting a dinner bill, or calculating ROI, percentages are everywhere. This tool covers every scenario: standard calculations, stacked discounts (e.g. "extra 20% off"), and reverse percentage lookups.
Double Discounts?
Retailers often advertise "Take an extra 20% off the sale price". This is notsimply adding the percentages (50% + 20% ≠ 70%). Our Discount Calculator handles this "stacking" logic correctly so you know the real price.
Percentage Change
Use this to track growth or loss. The formula (New - Old) / Old * 100tells you the relative change. Useful for stock analysis, weight tracking, or measuring website traffic growth.
