What next?
Cumulative GPA moves slowly. These show what would move it.
What your result means
CGPA weights each module’s grade point by its credit hours, so a heavy module influences your average more than a light one. The percentage equivalent is a rough proportional conversion — institutions use their own conversion tables, so treat it as indicative rather than official.
Why this one is different
The result shows its own working: total credit hours, total grade points, and how many modules were counted — the three figures the average is built from. If a number looks wrong, you can see which input caused it. The percentage equivalent is labelled institution-specific, because that conversion belongs to your university rather than to the maths.
Not every module moves your average by the same amount
A perfect score in a two-credit elective and a mediocre one in a six-credit core module do not cancel out. The core module carries three times the weight, which is why credit hours belong in the calculation and a plain average of grade points does not work.
It also means recovery is possible. A poor early semester matters less as total credits accumulate, because each new module is a smaller share of a growing denominator.
How it works
Multiply each module’s grade point by its credit hours to get quality points, add those across all modules, then divide by the total credit hours taken. The result is your cumulative grade point average on whichever scale your institution uses.
How to use this calculator
- Enter one module per line as name, grade point, credit hours.
- Pick the scale your institution grades on.
- Read your CGPA and the total credit hours it covers.
- Add future modules with predicted grades to see where you would land.
Formula
Quality points are the numerator. The same formula works on any scale — 4.0, 5.0 or 10-point — as long as all grade points use the same one.
Example calculation
Maths 3.7 (4 credits), Physics 3.3 (3 credits), English 4.0 (2 credits):
Total credits = 9
CGPA = 32.7 ÷ 9 = 3.63
CGPA, SGPA and how they relate
An SGPA summarises a single semester; a CGPA is the weighted average across all semesters completed so far, with credits as the weights. A CGPA is therefore not the average of the SGPAs unless every semester carried identical credit — a common and consequential shortcut. As a programme progresses the CGPA also becomes progressively harder to move, because each new semester is a smaller share of a growing total: the same result that shifted the average sharply in year one barely registers in year three.
Percentage conversion is institution-specific
Conversion formulas such as multiplying CGPA by 9.5 are institutional conventions, not standards — that particular one comes from a specific board and does not apply everywhere. Others subtract a constant, use a lookup table, or refuse conversion altogether. When a figure is going onto an application, use the formula the receiving institution publishes and state the scale alongside the number. A CGPA quoted without its scale is ambiguous, and a converted percentage without its formula is unverifiable.
Frequently asked questions
What is the difference between GPA and CGPA?＋
GPA usually refers to a single term or semester; CGPA is cumulative across everything you have studied. The arithmetic is identical — CGPA just includes more modules.
How do I convert a letter grade to a grade point?＋
On a 4.0 scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0 and so on. Your institution publishes its own table, and small variations are common.
Do failed or retaken modules count?＋
It depends on the institution. Some replace the original grade entirely, others average both attempts, and some keep the fail in the denominator. Check your regulations before relying on a projection.
Is CGPA the same as a percentage?＋
No, and no single formula converts between them reliably. Some institutions publish a multiplier, often around 9.5 for a 10-point scale, but you should use your own institution's published table.
How do credit hours affect the result?＋
Each module's grade point is weighted by its credit value, so a 20-credit module moves your CGPA twice as much as a 10-credit one at the same grade.
What counts as a good CGPA?＋
It depends entirely on the scale and the institution. On a 4.0 scale, 3.5 and above is usually considered strong; on a 10-point scale, 8.0 and above.
Can I raise my CGPA in a final year?＋
Less than most students expect. Once a large number of credits are banked, each new module carries a small share of the total, so early results dominate.

Assumptions & limitations
Every figure here comes from a simplified model. Keep these limits in mind when reading your result:
- Assumes all grade points use the scale you selected.
- Percentage equivalence is a proportional estimate, not an official conversion.
- Does not apply institutional rules for retakes, condoned fails or excluded modules.
