Exam Score Calculator
Convert raw exam marks to percentage, letter grade, and pass/fail status. See how many marks you need for the next grade band and compare against class average or highest score.
Marks Obtained → Percentage and Letter Grade

Scored 78/100 = 78% — Indian boards map to divisions (1st class ≥60%); US rubrics use A-F with ±. Negative marking in JEE reduces effective score: 4 correct − 1 wrong from 5 attempts = net 3/5 value.
When to use this calculator
Use after a single exam to get percentage. For semester-weighted final grade, use Grade.
Not what you need? For weighted multi-assignment course grade, use Grade calculator.

What is an Exam Score Calculator?
An exam score calculator converts marks obtained and total marks into a percentage, assigns a letter grade from US or Indian classification bands, and determines pass or fail against a threshold (default 33%). It also shows the marks gap to the next grade — for example, how many more points are needed to reach 90% (A) from 72% (C+).
Use this page immediately after a single test, board exam, or certification paper when you have raw marks and want pass/fail clarity plus class ranking context. Optional fields let you benchmark against class average and highest score.
For planning an entire course grade from weighted assignments and calculating what you need on the final exam, use the Grade Calculator. For converting a percentage to GPA or aggregating semester CGPA, use the Percentage to GPA or CGPA calculators.
Score Formula
Passing marks default to 33% of total marks if not specified. The grade gap shows how many more marks you need to reach the next grade band (or how many above passing you are).

Frequently Asked Questions
Exam percentage is calculated by dividing your marks obtained by the total marks and multiplying by 100. Formula: Percentage = (Marks Obtained ÷ Total Marks) × 100. For example, 72 out of 100 is 72%, while 135 out of 150 is (135 ÷ 150) × 100 = 90%. The same formula applies regardless of the total marks scale.
A distinction is the highest academic classification, typically awarded for 75% and above (in Indian and many Commonwealth educational systems). Some institutions require 80%+ or 85%+ for distinction. In the US grading system, a distinction roughly corresponds to an A grade (90%+). A distinction on your transcript signals exceptional academic achievement to employers and graduate schools.
Exam grades are assigned based on percentage ranges defined by the grading scale. Common systems include: US scale (A: 90%+, B: 80–89%, C: 70–79%, D: 60–69%, F: below 60%) and the Indian standard scale (Distinction: 75%+, First Class: 60–74%, Second Class: 50–59%, Pass: 33–49%, Fail: below 33%). Your institution may use slightly different cutoffs, so always check your official grade policy.
A passing mark is the minimum score required to pass an exam or course. In India, the standard passing percentage is 33% (or 35% in some states) for secondary and higher secondary education. University-level courses often use 40% or 50% as the minimum passing threshold. Professional courses like law, medicine, and engineering frequently require 50% or higher to pass individual subjects.
