Percentage Guide
Percentages express a number as a fraction of 100. The word comes from Latin "per centum" meaning "by the hundred". Percentages are used everywhere: discounts, taxes, statistics, grades, interest rates, and growth metrics.
Our calculator handles five common calculations: X% of Y, X is what % of Y, percentage change, adding a percentage, and subtracting a percentage.
