What This Calculator Does
GPA (Grade Point Average) is the weighted average of your course grades, where each course’s grade points are multiplied by its credit hours. This tool supports four grading scales used internationally:
- US 4.3 scale — Used by about half of US universities. A+ counts as 4.3, allowing exceptional students to exceed 4.0.
- US 4.0 scale — Caps at 4.0 (no A+ bonus). Common in state university systems and high schools.
- Indian 10.0 scale — Used by VTU, Anna University, SRM, VIT and most Indian engineering institutions.
- Percentage 0-100 — Direct percentage input, common in Indian K-12 schools and some universities.
How It Works
- Pick a grading scale at the top. The grade dropdown updates to match.
- Add semesters using the button at the bottom. Each semester holds its own course list.
- Add courses within each semester. Enter name (optional), credits, grade, and weight (for Honors/AP/IB).
- Add prior GPA if you have completed semesters before this view. It folds into the cumulative calculation.
- Read the results on the right: cumulative GPA, current semester GPA, total credits, and quality points.
- Plan ahead with the Target GPA Planner to see what you need in upcoming courses.
- Convert between percentage and GPA scales with the converter panel.
Why This Beats Asking an AI Chatbot
AI chatbots are inconsistent with GPA math. They forget to weight by credit hours, mix up grading scales, treat Indian percentages as if they were US 4.0, ignore W (Withdrawal) and P (Pass) edge cases, and cannot track cumulative calculations across semesters or save your work between prompts. They give a different answer every time you ask.
This calculator uses the standard weighted-average formula exactly, supports four international scales, handles every edge case, persists your work in browser localStorage so it survives a refresh, and prints a clean transcript-style output. It is the same math your registrar uses.
Frequently Asked Questions
How is GPA calculated?
GPA is the weighted average of grade points, where each course’s grade point is multiplied by its credit hours. The formula is:
GPA = Σ(grade_points × credits) / Σ(credits)
For example, a 4-credit A (4.0 points) and a 3-credit B (3.0 points) gives GPA = (4×4 + 3×3) / (4+3) = 25/7 = 3.57. The calculator does this math for every course, including prior GPA integration and weighted courses.
What is the difference between US 4.0 and US 4.3?
The US 4.0 scale treats A as the top grade worth 4.0 points. The US 4.3 scale allows A+ to count as 4.3 points, slightly rewarding exceptional performance. About half of US colleges use the 4.3 scale; the other half cap at 4.0. Check your transcript or registrar to see which one applies.
How does the Indian 10-point scale work?
The Indian 10-point scale is used by VTU, Anna University, SRM, VIT, and most Indian engineering colleges. Common grade-to-point mappings:
- O (Outstanding) = 10
- A+ = 9
- A = 8.5
- B+ = 7.5 (or 8 in some universities)
- B = 6.5 (or 7 in some universities)
- C = 5.5 (or 6 in some universities)
- D = 5 (pass mark)
- F = 0 (fail)
Some universities use slight variations — check your university’s grading memo.
What counts as a good GPA?
US 4.0 scale: 3.7+ is competitive for top universities, 3.5+ is strong for most graduate programs, 3.0+ meets the minimum for many graduate schools, below 2.0 typically triggers academic probation.
Indian 10.0 scale: 9.0+ is distinction, 8.0+ is first class with distinction, 7.0+ is first class, 6.0+ is second class, below 5.0 is fail.
Dean's list eligibility in the US usually requires 3.5+ semester GPA. This calculator highlights probation and honor roll zones automatically.
How do I calculate cumulative GPA across years?
Use the Prior Cumulative GPA section. Enter your previous cumulative GPA and total credits completed before the semesters you are entering above. The calculator adds the prior GPA contribution (prior_GPA × prior_credits) to the current contribution and divides by the total credits.
Example: prior 3.4 GPA over 60 credits + this semester 3.8 over 15 credits = (3.4×60 + 3.8×15) / 75 = (204 + 57) / 75 = 3.48 cumulative.
How do I use the target GPA planner?
Enter your current cumulative GPA, total credits completed so far, your target cumulative GPA, and how many credits you plan to take next. The calculator shows the GPA you need in those upcoming credits to hit your target. If the required GPA exceeds the scale maximum (4.0 US or 10.0 Indian), the calculator tells you that the target is mathematically unreachable without retaking courses.
Are Honors and AP courses weighted differently?
Yes. In the US high school system, Honors courses typically add 0.5 points to the base grade (B becomes 3.5), AP and IB courses typically add 1.0 point (B becomes 4.0), and College-level courses can add up to 1.0 point. The calculator applies these bonuses automatically when you set the course weight in the dropdown.
What about W, P, NP, and I grades?
W (Withdrawal), P (Pass), NP (No Pass), and I (Incomplete) are excluded from GPA calculation. They appear in your transcript but do not count toward the weighted average. The calculator automatically ignores these grades when computing your GPA.
Is my transcript data private?
Yes. Everything runs in your browser using JavaScript and your own localStorage. No grades, credits, or names are sent to any server. Close the tab and your current calculation is gone (unless you saved a snapshot). The auto-save feature only writes to your browser’s local storage on your device. There is no signup, no tracking, and no analytics tied to your grades.
