Percentage to GPA Calculator: Four Scales, Letter-Grade Accurate
Two ways to enter your score: type in your percentage directly, or enter your marks obtained and total marks, and the calculator works out the percentage for you.
The result shows your GPA on four scales simultaneously, 4.0 (US standard), 5.0, 7.0 (Australia), and 10.0 (India/international), so you can fill in whatever scale an application asks for without running a second conversion.
One thing worth knowing: this calculator converts through a letter grade first, not a simple ÷25 formula. That gives you a result that matches how universities actually assign GPA from percentage bands. More on that below.
How the Conversion Actually Works
Most online percentage-to-GPA converters use a single formula: divide your percentage by 25 (or multiply by 0.04) to get a 4.0 GPA. That gives 85%, which is a 3.4 GPA.
This calculator takes a different approach and produces a different answer.
Step 1: Your percentage is mapped to a letter grade using standard thresholds. On the US scheme (default): 93%+ = A, 90–92% = A–, 87–89% = B+, 83–86% = B, 80–82% = B–, and so on. An 85% score falls in the B range.
Step 2: That letter grade is then converted to a GPA value. B on a 4.0 scale = 3.0. Not 3.4.
This letter-grade intermediary is how universities actually work: they assign letter grades from percentage bands, then apply fixed GPA values to each letter. The simple ÷25 formula skips this step and produces decimal GPAs (3.4, 3.367…) that do not correspond to any actual letter grade.
Why Our Result Differs from Other Calculators
If you have seen other sites say 85% equals a 3.4 GPA, they are using the proportional formula: (85 ÷ 100) × 4.0 = 3.4. That is a quick approximation; it treats GPA as a pure linear scale.
The problem is that real university grading does not work that way. A student with 85% and a student with 86% both receive a B and a 3.0 GPA. The one-point percentage difference does not become 0.025 extra GPA points; the band absorbs it.
| Percentage | Proportional GPA | Letter | Letter-Based GPA |
|---|---|---|---|
| 93% | 3.72 | A | 4.0 |
| 90% | 3.60 | A– | 3.7 |
| 87% | 3.48 | B+ | 3.3 |
| 85% | 3.40 | B | 3.0 |
| 83% | 3.32 | B | 3.0 |
| 80% | 3.20 | B– | 2.7 |
| 75% | 3.00 | C+ | 2.3 |
For graduate school applications, the letter-based GPA is the more accurate figure. Universities reviewing transcripts use letter grades and their fixed GPA equivalents, not continuous proportional decimals.
Percentage to GPA Conversion Table: Quick Reference
Common percentage scores and their GPA equivalents using the US letter-grade standard:
| Percentage | Letter Grade | GPA (4.0) | GPA (5.0) | GPA (7.0) | GPA (10.0) |
|---|---|---|---|---|---|
| 93–100% | A | 4.0 | 5.0 | 7.0 | 10.0 |
| 90–92% | A– | 3.7 | 4.625 | 6.475 | 9.25 |
| 87–89% | B+ | 3.3 | 4.125 | 5.775 | 8.25 |
| 83–86% | B | 3.0 | 3.75 | 5.25 | 7.5 |
| 80–82% | B– | 2.7 | 3.375 | 4.725 | 6.75 |
| 77–79% | C+ | 2.3 | 2.875 | 4.025 | 5.75 |
| 73–76% | C | 2.0 | 2.5 | 3.5 | 5.0 |
| 70–72% | C– | 1.7 | 2.125 | 2.975 | 4.25 |
| 67–69% | D+ | 1.3 | 1.625 | 2.275 | 3.25 |
| 60–66% | D | 1.0 | 1.25 | 1.75 | 2.5 |
| Below 60% | F | 0.0 | 0.0 | 0.0 | 0.0 |
These thresholds follow common US university grading. Your institution may use slightly different cutoffs; the calculator’s threshold editor lets you adjust them.
Marks to GPA: If You Have Raw Marks, Not a Percentage
Indian, Pakistani, and many other Asian university exams give students raw marks rather than a percentage, for example, 450 out of 600, or 72 out of 100 in a subject.
Most tools force you to do the percentage calculation yourself first. This calculator has a built-in marks field: enter your marks obtained and the total marks, and it calculates your percentage automatically before converting to GPA.
Example: 450 marks out of 600 = 75%. Under US thresholds, 75% = C+, which is 2.3 GPA on a 4.0 scale.
The four-scale output then shows 75% across all scales: 2.3 on 4.0 / 2.875 on 5.0 / 4.025 on 7.0 / 5.75 on 10.0.
This is particularly useful for students at Indian universities, where each subject is marked individually, and you may need to average results across subjects before applying the conversion.
Percentage to GPA for Indian Students Applying Abroad
Most Indian universities record academic performance as a percentage, a CGPA on a 10-point scale, or both. US and Canadian universities use a 4.0 GPA scale. When you’re filling out an international application, you’ll almost always need to provide a GPA.
If your Indian transcript shows a percentage: Use this calculator. Enter your percentage, select the US Letters scheme, and target scale 4.0. The GPA shown is your equivalent for international applications.
If your transcript shows CGPA on a 10-point scale: Enter your CGPA as the marks obtained, 10 as the marks total, or use the GPA to CGPA calculator for direct scale conversion.
Which formula do universities actually use? Many US universities accept self-reported conversions for initial applications. Final decisions often require official evaluation by WES (World Education Services) or a similar credential evaluator. Check the admissions page before relying on any self-calculated GPA for official submission.
Percentage to GPA on Different Scales
The calculator shows your GPA on 4.0, 5.0, 7.0, and 10.0 simultaneously. Here is when each applies:
4.0 scale: US colleges, most Canadian universities, most international graduate program applications.
5.0 scale: Some Nigerian universities, a handful of Canadian institutions. If applying to schools that use 5.0, read off the 5.0 column.
7.0 scale: Australian universities (HD = 7, D = 6, CR = 5, P = 4). If you’re converting for Australian applications, use the 7.0 result.
10.0 scale: Indian CGPA equivalent, some European and international systems. If an employer or institution requests a CGPA on a 10-point scale, the 10.0 column provides the approximate equivalent.
FAQ: Percentage to GPA Calculator
What is 85% in GPA?
On a 4.0 scale using US letter-grade thresholds, 85% falls in the B range (83–86%), which equals a 3.0 GPA. Using the simple proportional formula (85 ÷ 100 × 4), it would be 3.4, but that figure doesn’t correspond to any real letter grade. Most university applications use the letter-grade method.
What is 90% in GPA?
90% = A– on the US scale = 3.7 GPA on a 4.0 scale. Proportionally, 90 ÷ 100 × 4 = 3.6; the letter-based result (3.7) is slightly higher because A– carries a fixed 3.7 value.
What is 75% in GPA?
75% = C+ (73–79% range) = 2.3 GPA on a 4.0 scale. On a 5.0 scale: 2.875. On a 10.0 scale: 5.75.
What is 80% in GPA?
80% = B– (80–82% range) = 2.7 GPA on a 4.0 scale. Proportionally: 80 ÷ 100 × 4 = 3.2, again, the letter-grade result differs because B– carries a fixed 2.7 value.
What is 70% in GPA?
70% = C– (70–72%) = 1.7 GPA on a 4.0 scale. This is below the 2.0 minimum required for most US graduate programs.
How do I convert marks to GPA without first calculating the percentage?
Enter your marks obtained and the total marks in the two mark fields. The calculator automatically converts them to a percentage, then to GPA. For example, 360 out of 450 = 80% = 2.7 GPA on a 4.0 scale.
Why does this calculator give a different answer from other GPA converters?
Most converters use a proportional formula: (percentage ÷ 100) × 4.0. This yields continuous decimal values such as 3.4 or 3.367. This calculator first maps your percentage to a letter grade, then applies the fixed GPA value for that letter. Since universities actually use letter-grade bands, this method more closely matches how GPA is assigned in practice. An 85% score is a B, and B = 3.0, not 3.4.
Can I use this to convert a percentage to GPA for a US master’s application?
Yes, for an estimate. Enter your percentage; use the US Letters scheme; target scale: 4.0. Many universities accept self-reported conversions for initial applications, but competitive programmes and official admissions often require a WES or ECE evaluation. Always confirm with the programme before submitting a self-calculated GPA as your official academic record.
Enter your percentage or raw marks above, choose your target scale, and the result shows your equivalent GPA across 4.0, 5.0, 7.0, and 10.0 scales simultaneously. To convert a GPA to a percentage, use the GPA-to-percentage calculator.
