GPA / CGPA Calculator (Grade Point Average)
Calculate your weighted GPA (Grade Point Average, or CGPA across semesters) from course grades and credit hours.
What Is the GPA / CGPA Calculator (Grade Point Average)?
GPA (Grade Point Average) measures academic performance as a single weighted number, condensing a semester — or an entire academic record — into one figure that admissions committees, scholarship boards, and employers can compare at a glance. Because it's a weighted average rather than a simple one, GPA correctly accounts for the fact that a 4-credit core course should influence your standing more than a 1-credit lab or seminar.
Grading conventions vary widely between countries, and even between institutions in the same country. US colleges and high schools typically use a 4.0 letter-grade scale (sometimes stretched to 4.3 or 4.5 to reward AP or honors work), Indian universities operating under UGC and AICTE norms commonly report a 10-point CGPA using letter grades like O, A+, A, B+, B, C, and P, and some institutions elsewhere skip points entirely and report a straight percentage. CGPA (Cumulative GPA) applies the exact same weighted-average formula across every semester completed so far, rather than just the courses in a single term.
Before calculating your GPA, it can help to know exactly where you stand in a single course — the Grade Calculator breaks down a weighted score from individual assignments, quizzes, and exams. And if you're trying to protect a target GPA through finals week, the Exam Countdown tool can help you plan study time across every exam still ahead.
GPA / CGPA Calculator (Grade Point Average) Formula
GPA = Σ(Credit Hours × Grade Points) ÷ Σ(Credit Hours)
How Is the GPA / CGPA Calculator (Grade Point Average) Calculated?
Each course's grade is converted to grade points (A = 4.0, B = 3.0, and so on) and multiplied by its credit hours, since a 3-credit course counts three times as much toward your average as a 1-credit course. These weighted points are summed and divided by the total credit hours to get the final GPA.
This weighting matters most when your course load is uneven — a student who takes one 4-credit A and one 1-credit Pass/Fail seminar shouldn't see the seminar dilute the GPA nearly as much as an unweighted average would suggest. It's also why simply averaging semester GPAs together to get a CGPA is technically imprecise unless every semester carried the same total credit load — the more accurate approach is to weight each semester's GPA by its own credit hours, exactly as this calculator does when you add one row per semester.
GPA / CGPA Calculator (Grade Point Average) Example
4.0 scale: three courses — A (3 credits), B+ (4 credits), and A- (3 credits) — give a GPA of (3×4.0 + 4×3.3 + 3×3.7) ÷ 10 = 3.63.
10-point scale: an O grade (4 credits), an A+ grade (3 credits), and a B+ grade (3 credits) give a CGPA of (4×10 + 3×9 + 3×7) ÷ 10 = 8.80.
CGPA across semesters: a first semester GPA of 3.5 over 15 credits combined with a second semester GPA of 3.8 over 16 credits gives a cumulative GPA of (3.5×15 + 3.8×16) ÷ 31 = 3.65 — enter each semester's GPA and credit total as one row to approximate this.

Understanding Your Result
The result is your credit-weighted average on the scale you selected. On a 4.0 scale, most institutions consider 3.5+ excellent, 3.0–3.49 good, and 2.0–2.99 satisfactory. On a 10-point scale, 8.5+ is typically excellent and 6–7.5 good. Exact honors and probation cutoffs vary by institution.
These bands are only a general guide — some universities set Latin honors (cum laude, magna cum laude) at specific GPA cutoffs like 3.5 or 3.8, while academic probation thresholds are commonly set around 2.0. Always check your own institution's official policy handbook rather than relying on generic bands like these for decisions that actually matter, such as financial aid or academic standing.
Tips
- For CGPA, add one row per completed semester using that semester's GPA and total credits as the 'grade' and 'credits' — see the FAQ below for how to approximate this.
- Double-check your school's specific grade-point scale, since some use slightly different values (e.g. no A+ at 4.0, a 4.3 scale, or a different 10-point letter mapping).
- Remove pass/fail or audited courses if your school excludes them from GPA.
- If your transcript reports plus/minus grades (like A- or B+) but you're unsure your institution assigns different point values for them, check your registrar's official grading policy before assuming the standard 0.3 step used here.
- When estimating a future semester's effect on your CGPA, add a placeholder row with your best-guess grade and credits, then swap in the real grade once it posts.
Common Mistakes
- Averaging grades without weighting by credit hours, which understates the impact of larger courses.
- Forgetting to include a low-credit course, which can still shift the average.
- Mixing a 4.0 scale with a 10-point or percentage scale from a different grading system.
- Treating an incomplete or withdrawn course as if it carries full credit hours, when many institutions exclude these from the GPA calculation entirely.
- Rounding intermediate grade points before the final division, which can introduce small errors — this calculator keeps full precision until the very last step.
Frequently Asked Questions
What's the difference between GPA and CGPA?
GPA usually refers to a single semester's weighted average, while CGPA (Cumulative GPA) is the weighted average across all semesters completed so far. Both use the same underlying formula.
How do I calculate my CGPA with this tool?
Add one row per semester, entering that semester's total credit hours as "credits" and its GPA rounded to the nearest listed grade as the "grade" — or use the closest letter equivalent (e.g. a 3.7 semester GPA ≈ A-).
Does this support a 10-point or percentage grading scale?
Yes — use the Grading Scale selector at the top to switch between the 4.0 scale (US), the 10-point scale used by Indian universities under UGC/AICTE norms (O/A+/A/B+/B/C/P/F), or a straight percentage.
Why does a 1-credit course affect my GPA less than a 3-credit course?
Because GPA is a credit-weighted average — a course worth more credit hours contributes proportionally more grade points to your total, which is exactly what real transcripts calculate.
What is the difference between weighted and unweighted GPA?
Weighted GPA gives extra points for harder courses (like AP or honors classes), while unweighted GPA treats all courses equally regardless of difficulty — check which type your institution uses.
Can I calculate my GPA for just one semester instead of my whole academic record?
Yes — enter only the courses and grades from the semester you want to calculate, rather than your full academic history.
How do I convert a percentage grade to GPA points?
Conversion scales vary by institution — many use a formula or lookup table (like percentage ÷ 9.5 for a common Indian 10-point conversion) to translate percentages into GPA points; check your institution's specific method.
Does a failing grade still count toward my GPA?
Yes, in most systems a failing grade is included in the GPA calculation with its corresponding low grade point value (often 0), which is why failing courses can significantly lower your overall GPA.
What's a competitive GPA for university applications?
This varies enormously by institution, country, and program — check the specific admissions requirements or averages published by your target schools rather than relying on a generic benchmark.
Can I share my GPA result as an image?
Yes — tap Share and, on supported devices, your GPA is shared as a branded image card, not just a text link.
Does a Pass/Fail course count toward my GPA?
Most institutions exclude Pass/Fail courses from the GPA calculation entirely, since a Pass doesn't carry a standard grade point value — check your school's policy, and leave those courses out of this calculator if they're excluded from your official GPA.
Can I use this calculator for a UK degree classification instead of GPA?
Not directly — UK universities typically classify degrees (First, Upper Second, Lower Second, Third) using an entirely different weighting system based on module marks rather than a US-style GPA, so this calculator's point tables won't map onto that system.
What's a typical GPA scale outside the US and India?
It varies enormously — some countries use a 5-point or 7-point scale, others report only percentages or degree classifications with no numeric GPA at all, so always check what scale your specific institution or destination country expects.
Why is my calculated GPA slightly different from what my school reports?
Small differences are usually about excluded courses (like Pass/Fail, withdrawals, or repeats) or a slightly different point mapping for plus/minus grades — check your registrar's exact policy and grade-point table to reconcile any gap.
