Percentage Calculator
Percentage of a number, marks percentage, and increase or decrease
Marks to percentageSubject-wise, with best-of-5 for CBSE
Application forms usually want two decimal places and never accept a rounded-up figure that crosses an eligibility threshold; recruiters recompute the percentage themselves at document verification. Best-of-5 follows the CBSE convention (five highest subjects); universities and recruiters may count all subjects, so check the notification.
About this tool
Four calculations cover almost every percentage question that comes up while filling a form or checking a result: a percentage of a number, one number as a percentage of another, marks out of a total, and the percentage change between two values.
Each mode shows the working, not just the answer, so you can check the arithmetic before you write it into an application form.
Frequently asked questions
›How do I convert marks to a percentage?
Divide marks obtained by maximum marks and multiply by 100. For 438 out of 500, that is 438 ÷ 500 × 100 = 87.6%.
›What is the difference between percentage change and percentage points?
A move from 40% to 50% is a 10 percentage point rise, but a 25% increase. Application forms almost always want the plain percentage.
›How many decimal places should I write?
Two is standard for exam and admission forms unless the form specifies otherwise. Never round up to cross an eligibility threshold; recruiters compute it themselves.
