How to calculate percentage — formula & examples

Few ideas turn up as often as percentages — they run through exam results, shop sales and pay revisions alike. Since "percent" comes from "per hundred", a percentage is nothing more than a part of 100.

Formula 1 — marks percentage: (Marks Obtained ÷ Total Marks) × 100. A score of 432 out of 600 becomes 432/600 × 100 = 72%.

Formula 2 — percentage increase: when a score climbs from 60 to 75, the jump is (75−60)/60 × 100 = 25%.

Formula 3 — percentage decrease: a price sliding from ₹500 to ₹400 is (500−400)/500 × 100 = 20% off.

Indian board exams: because CBSE reports marks one subject at a time, your aggregate = total marks across subjects ÷ total maximum marks × 100. Plenty of colleges then apply a Best-of-5 or Best-of-4 rule, so read your college's own eligibility criteria carefully.

Not every exam counts a percentage the same way — for board-exam admissions, first confirm whether Best-of-4, Best-of-5 or the full aggregate applies.

Frequently asked questions

How do I calculate the percentage of marks?
Divide the marks you got by the total and multiply by 100 — 450/500 × 100 = 90%. The "Marks %" tab above does it for you in one tap.
What is the formula for percentage increase?
Percentage increase = (New Value − Old Value) / Old Value × 100. A salary going from ₹25,000 to ₹30,000 is (30,000−25,000)/25,000 × 100 = 20%.
How do I calculate percentage decrease?
Percentage decrease = (Old Value − New Value) / Old Value × 100 — the formula behind discounts, price drops and falling scores.
What percentage is X of Y?
Divide X by Y and multiply by 100. Take 45 out of 200: 45/200 × 100 = 22.5%. The "What % is X of Y?" tab above handles it instantly.
How do I find X% of a number?
Multiply the number by X, then divide by 100 — 15% of 800 = 800 × 15 / 100 = 120. Try the "X% of Y" tab above.
