How is a weighted GPA calculated?

Each course grade is converted to a grade point (e.g. A = 4.0 on the US scale), multiplied by its credit hours, and then divided by the total credit hours. Courses with more credits count more toward the result.

What UK Honours classes does this cover?

First-class (First), Upper Second-class (2:1), Lower Second-class (2:2), Third-class (Third), and Fail — matching the standard British undergraduate classification system.

What grade points does the US 4.0 scale use?

A and A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, D− = 0.7 and F = 0.0. These are the common US college points multiplied by each course's credit hours.

How does the India 10-point CGPA scale map letters to points?

O (Outstanding) = 10, A+ = 9, A = 8, B+ = 7, B = 6, C = 5, P (Pass) = 4 and F = 0. Your CGPA is the credit-weighted average of these grade points out of 10.

What's the difference between GPA and CGPA?

GPA usually refers to a single term or semester, while CGPA (cumulative GPA) is the weighted average across all terms. The maths is identical — this tool computes a weighted average of whatever courses you enter, so you can use it for either.

How do credit hours change my GPA?

Each grade is weighted by its credit hours, so a high grade in a 4-credit course moves your average more than the same grade in a 1-credit course. Courses with zero or blank credits are ignored.

GPA calculator — US, UK and India

Enter your courses, grades and credit hours and get your weighted GPA instantly — no sign-in, no uploads. Built for students checking where they stand before final results, applicants converting grades between systems, and anyone planning the marks they need next term. Supports three grading systems: the US 4.0 scale, UK Honours classification (First through Third) and the India 10-point CGPA.

How it works

Each course grade is mapped to a grade point, multiplied by that course’s credit hours, and summed. The weighted GPA is that sum divided by the total credit hours: GPA = Σ(gradePoint × credits) ÷ Σ(credits). Because of the weighting, courses worth more credits pull the average harder. On the UK setting, classes map to points (First = 1, 2:1 = 2.1, 2:2 = 2.2, Third = 3) and the result is labelled with the matching honours class. Blank grades and courses with zero credits are skipped, and the result only appears once at least one valid graded course is entered.

Worked example

Three US courses — an A (4.0) worth 3 credits, a B+ (3.3) worth 4 credits, and a B (3.0) worth 3 credits — give (4.0×3 + 3.3×4 + 3.0×3) ÷ (3+4+3) = (12 + 13.2 + 9) ÷ 10 = 3.42 / 4.0.

Grade conversion reference table

Letter	US 4.0	India 10-point	UK class
A+ / O	4.0	10	First
A	4.0	8	First
B+	3.3	7	2:1
B	3.0	6	2:1
C	2.0	5	2:2
D	1.0	4	Third
F	0.0	0	Fail

System-specific notes

US 4.0 scale

The US 4.0 scale uses plus/minus grades (A−, B+, B, B−, etc.) with each step worth 0.3 or 0.7 grade points. An A+ is conventionally capped at 4.0 on an unweighted scale; some schools award 4.3 for A+ on a weighted scale but this tool uses the standard unweighted 4.0 ceiling. Pass/Fail courses carry no grade points and should be left out of the calculation.

UK Honours classification

UK degrees classify the overall degree rather than assigning a numeric GPA. The tool reports your weighted result alongside the band it falls in. Most English universities require a First-class average of 70% or above and a 2:1 of 60% or above, but exact boundaries vary — some institutions use a borderline zone of 68–70% with discretionary conferral. Use this tool for tracking; consult your institution’s regulations for precise thresholds.

India 10-point CGPA

Indian universities following the UGC credit framework use O (Outstanding), A+, A, B+, B, C, P (Pass), and F. The tool maps these to the 10-point scale and computes CGPA (cumulative grade point average) across all entered courses. To convert CGPA to percentage, most institutions use the CBSE rule of multiplying by 9.5, though some publish their own multipliers.

Common use cases

Checking your standing before finals: enter grades received so far plus estimated grades for incomplete courses to project where you will land
Graduate school eligibility: benchmark against the GPA requirements (typically 3.0/4.0 for US graduate admissions or a 2:1 for UK postgraduate programmes)
Cross-system comparison: students moving between countries need a consistent way to explain their academic record to admissions committees abroad
