Common percentage formulas
Percentage of a number: value × percentage ÷ 100.
What percent A is of B: A ÷ B × 100.
Example
18% of ₹2,000 is ₹360 because 2,000 × 18 ÷ 100 = 360.
Important considerations
Percentage points and percentage change are not the same thing. For example, moving from 10% to 15% is an increase of 5 percentage points but a 50% relative increase.
Limitations
The calculator performs the mathematical operation you select; it does not determine whether a particular percentage is legally, financially or commercially applicable.
