How to Use

  1. 1 Pick your grading scale: 4.0, 10.0 (CGPA), or percentage
  2. 2 Add each subject with its letter grade and credit hours
  3. 3 Use 'Add subject' for more rows; remove any you don't need
  4. 4 Read your weighted GPA, classification, and total credits instantly
  5. 5 Adjust grades or credits to see how your GPA changes live

Features

  • Three grading scales: US 4.0, Indian 10.0 CGPA, and percentage
  • Credit-weighted average — heavier courses count more, just like your transcript
  • Add or remove unlimited subjects with one tap
  • Live recalculation as you type — no Calculate button needed
  • Plain-English classification (Excellent, Very Good, Good…)
  • Runs entirely in your browser — your grades are never uploaded

Why it Matters

Your GPA is a single number that scholarships, internships, and graduate programs lean on heavily, yet it is weighted by credit hours rather than a simple average — which is easy to get wrong by hand. Calculating it correctly helps you track progress, set realistic targets, and spot which courses move the needle most. Seeing the result update live makes 'what grade do I need' planning effortless.

What this tool does

The GPA Calculator turns a list of subjects, grades, and credit hours into a single weighted Grade Point Average. Choose the 4.0, 10.0 (CGPA), or percentage scale, add your courses, and your GPA, classification, and total credits appear instantly.

How it works

GPA is a credit-weighted average, not a plain mean. Each course’s grade points are multiplied by its credit hours, the results are summed, and the total is divided by the total credit hours. The logic is a pure function, so the same subjects always produce the same GPA.

Informational only

Grade-point scales and rounding rules differ between institutions. This tool uses widely-used conventions for guidance — your official transcript GPA is the one that counts.

Privacy

Everything runs locally in your browser. No grades are uploaded, logged, or stored.

Frequently Asked Questions

How is GPA calculated?
GPA is a credit-weighted average: multiply each course's grade points by its credit hours, add those products up, then divide by the total credit hours. A 4-credit A counts twice as much as a 2-credit A. This calculator does the weighting for you across every subject you add.
What's the difference between the 4.0 and 10.0 scales?
The 4.0 scale is the US standard, where an A is 4.0 grade points. The 10.0 scale (CGPA) is common in Indian universities, where the top grade O is worth 10 points. They measure the same idea on different ranges — pick the scale your institution uses.
How do I convert CGPA to a 4.0 GPA?
There is no single official formula — different schools and credential evaluators use different mappings. A rough approximation divides your CGPA by your scale's maximum and multiplies by 4 (e.g. 8.5/10 × 4 ≈ 3.4), but always check the specific conversion your target program accepts.
Is my data sent anywhere?
No. Everything is calculated in your browser. Your subjects, grades, and credit hours are never uploaded, logged, or stored — refreshing the page clears them.
Why is this tool informational only?
Grade-point values and rounding rules vary by institution. This calculator uses common conventions, but your official transcript GPA is the authoritative one — always confirm against your school's grading policy.
