Percentages appear everywhere — shop discounts, exam marks, profit margins, GST markup and salary hikes. A percentage calculator saves time and reduces errors when you need quick, accurate answers.
Basic percentage formula
Percentage = (Part / Whole) × 100
Example: 45 marks out of 60 = (45/60) × 100 = 75%.
Discount calculation
If MRP is ₹2,000 and discount is 25%, discount amount = 2000 × 25/100 = ₹500. Sale price = ₹1,500.
Percentage increase and decrease
Increase: New = Old × (1 + Rate/100). Decrease: New = Old × (1 − Rate/100). Use our Percentage Increase/Decrease tool for instant results.
