What Is a Percentage?
A number or ratio expressed as a fraction of 100. It is denoted using the symbol “%”. Understanding percentes is vital for comparing proportions, understanding change, and making better decisions in both personal and professional contexts.
For example:
- 25% of ₹1,000 is ₹250
- A 10% increase of ₹5,000 is ₹5,500
- A 15% discount on ₹2,000 means you pay ₹1,700
Our Online Calculator simplifies all of this—and more.
