About
Percentage is a free, offline percentage calculator for everyday math: shopping, tax, tips, marks, and practice.
WHAT YOU CAN CALCULATE
• What is X% of Y
• X is what percent of Y
• Find the whole from a part and a percent
• Increase and decrease by a percent
• Percent change and percent difference
• Sale price with one or two discounts, then optional tax
• Add or remove GST / VAT / sales tax
• Marks: score as a percent, and marks still needed for a target
• Tip and split the bill
STACKED DISCOUNTS ARE HONEST
Two discounts multiply. 20% then 10% off 100 is 72 — 28% off, not 30%. Tax is added after the discount.
PRACTICE
