Frequently asked questions
How do I calculate percentage increase?
Percentage increase = ((New value − Old value) / Old value) × 100. Example: salary goes from ₹50,000 to ₹60,000. Increase = ((60,000 − 50,000) / 50,000) × 100 = 20%. A negative result indicates a decrease.
How do I calculate percentage of a total?
Divide the part by the total and multiply by 100. Example: if you scored 85 out of 100, the percentage is (85/100) × 100 = 85%. For 250 out of 400, it's (250/400) × 100 = 62.5%.
What is 30% off a ₹1,500 item?
30% of ₹1,500 is (30/100) × 1,500 = ₹450. The discounted price is ₹1,500 − ₹450 = ₹1,050. Equivalent shortcut: multiply the original price by 0.7 (i.e., 70%).
