How to Calculate Your Grade Percentage
Step-by-step guide
1

Identify your marks obtained

This is the score you received on the exam or assignment. For multiple assignments, add them all up first.

2

Find the total possible marks

This is the maximum score achievable. If you have multiple assignments, add up all the maximum scores.

3

Divide and multiply by 100

Percentage = (Marks Obtained ÷ Total Marks) × 100. For 85/100: (85 ÷ 100) × 100 = 85%.

4

Look up your letter grade

Use the grading scale for your institution. 85% is a B in the US, a First in the UK, and an A in India.

Frequently Asked Questions

How do I calculate my overall grade from multiple assignments?
Add up all marks obtained, then divide by total possible marks. If you scored 85/100, 45/50, and 18/25: total obtained = 148, total possible = 175. Percentage = (148/175) × 100 = 84.6%. Don't average the percentages – that gives wrong results if assignments have different weights.
What's the difference between weighted and unweighted GPA?
Unweighted GPA treats all classes equally – an A in PE counts the same as an A in AP Physics. Weighted GPA gives extra points for honors/AP/IB classes. An A in AP might be 5.0 instead of 4.0. Weighted GPAs can exceed 4.0; unweighted cannot.
Is 70% a good grade?
Depends on the system. In the US, 70% is a C- (average). In the UK, 70% is a First (excellent – top classification). In India, 70% is an A (very good). Context matters. Graduate programs often require 3.0+ GPA (roughly 83%+) for admission.
How do I convert my grade to a different country's system?
Use a grade conversion tool or WES (World Education Services) guidelines. Rough guide: US A (90-100%) ≈ UK First (70%+) ≈ India O/A (80%+) ≈ Australia HD (85%+). But conversion isn't exact – different systems test different skills.
What GPA do I need for medical/law school?
Competitive US medical schools expect 3.7+ GPA (roughly 90%+). Top law schools want 3.8+. But GPA isn't everything – MCAT/LSAT scores, research, and extracurriculars matter too. State schools often have lower thresholds for in-state applicants.
