GPA Calculator

How the GPA calculator works

GPA (Grade Point Average) is the weighted mean of your grades, where each class's grade value is multiplied by its credit hours. The calculator converts each letter grade (or percentage, on the scales that use it) to a numeric value on your chosen scale, multiplies by credits to get quality points, then divides the sum of quality points by the sum of credits.

The Cumulative Projection panel combines an existing cumulative GPA with the new classes above — useful for answering "what will my cumulative be after this semester?" Results are shown on your chosen scale AND, if the scale isn't US 4.0, auto-converted to a US 4.0 equivalent for international applications.

Why this calculator beats a plain form

• 15+ regional grading scales — US 4.0 unweighted, US 4.0 with +/−, US 4.3 honors, India CGPA 10-point (UGC), India percentage bands, UK honours, Canada 4.0, Australia 7-point, Germany 1.0–5.0, France 0–20, Netherlands 1–10, Spain 0–10, Italy 0–30, China 0–100, Japan S/A/B/C/F, South Korea 4.5, Brazil 0–10, plus a Custom 0–100% fallback for any country not listed.
• Automatic US 4.0 conversion — international students applying to US colleges get a credit-weighted US 4.0 equivalent next to their native-scale GPA. Uses each grade's percentage midpoint mapped onto the US 4.0 unweighted scale.
• Show-the-work steps — every quality-point calculation is shown so students can learn the formula, not just get an answer.
• Cumulative projection mode — combine with an existing GPA and credit total to project the new cumulative.
• Worked examples per region — pick your country's scale and the example tabs swap to realistic local scenarios (US freshman semester, India B.Tech semester, UK honours year, German bachelor, French licence, etc.).
• Tabular class list — spreadsheet-style rows for fast entry, with a mobile-optimized layout.
• PDF export — print-friendly breakdown for homework, transcript submission, or academic advisor meetings.

Supported grading scales at a glance

• US 4.0 Unweighted: A=4.0, B=3.0, C=2.0, D=1.0, F=0.0. Standard US high-school / college scale.
• US 4.0 with +/−: Adds A− (3.7), B+ (3.3), etc. Most common college variant.
• US 4.3 weighted: A+ extends to 4.3 — used for honors / AP weighted cumulative GPA.
• India CGPA 10-point: UGC standard. O = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P = 4, F = 0.
• India Percentage Bands: First Class Distinction (≥75%), First Class (60–74%), Second Class (50–59%), Pass Class (40–49%).
• UK Honours: First (≥70%), Upper Second / 2:1 (60–69%), Lower Second / 2:2 (50–59%), Third (40–49%).
• Canada 4.0: A+ / A (85–100 = 4.0), A− (80–84 = 3.7), descending to F (<50 = 0.0).
• Australia 7-point GPA: HD (7), D (6), C (5), P (4), N (fail). Used by Go8 universities.
• Germany 1.0–5.0: Lower is better. 1.0 sehr gut, 2.0 gut, 3.0 befriedigend, 4.0 ausreichend (pass), 5.0 nicht bestanden (fail).
• France 0–20: Très bien (≥16), Bien (14–15), Assez bien (12–13), Passable (10–11). Pass mark is 10.
• Netherlands 1–10: 9–10 uitmuntend, 8 zeer goed, 7 goed, 6 voldoende (pass).
• Spain 0–10: Matrícula de Honor (9–10), Sobresaliente (9), Notable (7–8.9), Aprobado (5–6.9). Pass is 5.
• Italy 0–30: 30 e lode (with honours), 27–29 ottimo, 24–26 buono, 21–23 discreto, 18–20 sufficiente. Pass is 18.
• China 0–100: A (85–100), B (75–84), C (65–74), D (60–64), F (<60). Pass is 60.
• Japan S/A/B/C/F: S (秀 ≥90), A (優 80–89), B (良 70–79), C (可 60–69), F (不可 <60). Pass is 60.
• South Korea 4.5: A+ (4.5), A (4.0), B+ (3.5), B (3.0), … , F (0.0). Most common Korean uni scale.
• Brazil 0–10: A (9–10), B (8–8.9), C (7–7.9), D (6–6.9), E (<6). Pass varies by institution (6 or 7).
• Custom (0–100%): Raw percentage per class — covers any country not preset above.

How the US 4.0 conversion works

For international students, US admissions offices typically want a GPA on the 4.0 scale. This calculator computes a credit-weighted percentage across all your classes (using each grade's percentage midpoint on your chosen scale), then maps that average percentage onto the US 4.0 unweighted scale (90+ = 4.0, 80–89 = 3.0, etc.). It's an approximation — WES, ECE, and other credential evaluators may produce a slightly different number — but it's the standard method used by most conversion tables and gets you a sensible ballpark figure.
