What Is a GPA Calculator?
This GPA calculator converts your academic performance — whether you know it as a percentage, or as marks across your subjects — into an equivalent GPA on the 4.0, 5.0, or 10.0 scale. It works the same way whether you're using it as a college GPA calculator or a high school GPA calculator, since both typically rely on the same percentage-to-GPA conversion.
If you already know your percentage, use "Percentage → GPA". If you only have your subject-wise marks, use "Marks → GPA" and the calculator will work out your percentage first, then convert it to GPA.
How to Calculate GPA (Step-by-Step)
If you want to calculate GPA by hand instead of using the tool above, the process is straightforward once you know your percentage:
- Find your percentage. If you only have marks per subject, add up your obtained marks and divide by the total possible marks, then multiply by 100.
- Pick your GPA scale. Most US colleges and high schools use a 4.0 scale; a 5.0 scale usually applies to weighted GPA; a 10.0 scale is common in India and several other countries.
- Divide your percentage by the scale's divisor. Percentage ÷ 25 for a 4.0 scale, Percentage ÷ 20 for a 5.0 scale, or Percentage ÷ 9.5 for a 10.0 scale.
- Round to two decimal places — for example, an 88% on a 4.0 scale gives 88 ÷ 25 = 3.52 GPA.
This is exactly what the calculator above automates for you, including handling multiple subjects at once in "Marks → GPA" mode.
GPA Conversion Formula
Once your percentage is known, GPA is calculated using the following formulas depending on your scale:

GPA Calculator for College vs High School
The underlying math is the same whether you're using this as a college GPA calculator or a high school GPA calculator: percentage or marks are converted into a GPA using the divisor for your chosen scale. The main difference between college and high school GPA in practice is that many US high schools also report a weighted GPA alongside the standard (unweighted) one — see the section below.
Weighted vs Unweighted GPA
An unweighted GPA — which is what this calculator produces — treats every course equally regardless of difficulty, and is capped at 4.0 (or your selected scale's maximum). A weighted GPA gives extra points for harder courses such as Honors, AP, or IB classes, so it can go above 4.0, often up to 5.0.
Because weighting rules (how many extra points, for which courses) vary from school to school, this calculator focuses on the standard percentage/marks to unweighted-GPA conversion. If your school reports a weighted GPA, check with your counselor or registrar for its specific weighting scale.
What Is a Good GPA?
On the common 4.0 scale, a 3.5 GPA or higher is generally seen as good, 3.7 and above is considered very good, and a 4.0 GPA is a perfect unweighted score. What actually counts as "good" depends heavily on context though — your school's grading difficulty, your program, and the average GPA at your institution or the schools you're applying to all matter more than the raw number alone.
GPA for Cum Laude, Magna Cum Laude & Summa Cum Laude
Latin honors are typically awarded based on a minimum cumulative GPA, though exact cutoffs vary significantly between universities and are sometimes also tied to class rank rather than GPA alone. Commonly cited ranges are:
| Honor | Typical GPA Range (4.0 scale) |
|---|---|
| Cum Laude | Approximately 3.5 – 3.7 |
| Magna Cum Laude | Approximately 3.7 – 3.9 |
| Summa Cum Laude | Approximately 3.9 – 4.0 |
These ranges are common approximations, not a universal standard. Always check your own university's official Latin honors policy — some schools use different cutoffs, percentage-based thresholds, or reserve these honors for a fixed top percentage of the graduating class instead of a GPA cutoff.
Cumulative GPA vs Semester GPA
The GPA this calculator produces is based on the percentage or marks you enter for a single conversion — useful for one semester, one term, or one exam. Your cumulative GPA (CGPA) is different: it's the running average of every semester's GPA, weighted by credit hours, across your entire academic record. If you need to combine multiple semesters into one overall score, use our CGPA calculator instead.
GPA Scale Explained
A GPA scale is simply the range your grade point average is measured on:
- 4.0 scale — the most common scale, used by most US colleges and high schools for unweighted GPA.
- 5.0 scale — often used for weighted GPA, where advanced courses can push the score above 4.0.
- 10.0 scale — common in India and several other countries, sometimes shown as CGPA rather than GPA.
This calculator supports all three, so you can convert your percentage or marks into whichever scale your institution actually uses.
Why Conversion Formulas Vary
Different institutions use slightly different formulas to convert between percentage and GPA. This calculator uses the most widely accepted approximation for each scale — for anything official (transcripts, visa applications, job forms), always check your institution's stated formula.
Frequently Asked Questions
On a 10.0 scale, GPA is typically calculated as Percentage ÷ 9.5. On a 5.0 scale it's Percentage ÷ 20, and on a 4.0 scale it's Percentage ÷ 25.
Yes. Switch to "Marks → GPA" mode, add your subjects with obtained and total marks, and the calculator works out your percentage and GPA together in one step.
It's the most commonly used approximation. Some universities and schools publish their own official formula, so always confirm with your institution for documents that require an exact figure.
Yes. The percentage-to-GPA and marks-to-GPA formulas here are the same ones commonly used by colleges and high schools on the 4.0, 5.0, and 10.0 scales. If your high school uses a weighted scale for AP or Honors courses, see the weighted vs unweighted GPA section on this page.
An unweighted GPA, which is what this calculator produces, treats every course the same regardless of difficulty and is typically capped at 4.0. A weighted GPA adds extra points for Honors, AP, or IB courses, so it can go above 4.0, often up to 5.0. Check with your school counselor for its exact weighting scale.
A cumulative GPA, or CGPA, is your overall GPA averaged across every semester or term you've completed, rather than just one term. Use a dedicated CGPA calculator if you need to combine multiple semesters into one cumulative score.
On a 4.0 scale, a 3.5 GPA or higher is generally considered good, 3.7 and above is very good, and a 4.0 GPA is a perfect unweighted score. What counts as good also depends on your school, program, or your institution's average GPA.
Requirements vary widely by institution, but common ranges are roughly a 3.5 to 3.7 GPA for cum laude, 3.7 to 3.9 for magna cum laude, and 3.9 to 4.0 for summa cum laude. Always check your own university's official Latin honors policy, since exact cutoffs and class-rank rules differ between schools.
A GPA scale is the range your grade point average is measured on. The most common is 4.0, but some schools use a 5.0 scale, often for weighted GPA, or a 10.0 scale, common in India and some other countries. This calculator supports all three.
