GPA Calculator from Percentage
Enter your percentage and pick a GPA scale. On the 4.0 and 4.3 scales this tool uses the standard US letter-grade table for the accurate GPA; on the 5.0 and 10.0 scales it uses the proportional formula. The reference row always shows the simple 4.0, 5.0, and 10.0 conversions.
Your GPA (4.0 scale)
Simple proportional conversion (for credential evaluators / study abroad):
On the 4.0 scale the big number uses the standard US grade-band table (e.g. 85% = B = 3.0). The proportional row uses GPA = percentage ÷ 100 × scale max, which some international evaluators use instead.
The Two Ways to Convert a Percentage to GPA
There is no single official percentage-to-GPA formula. Two methods dominate, and they can give very different numbers — pick the one that matches your situation.
- The standard US letter-grade scale (recommended for US schools). Your percentage first maps to a letter grade (A, B+, B…), and each letter has a fixed GPA. For example, 85% is a B, which is 3.0 — not 3.4. This is how US high schools and colleges actually compute GPA, so it's the realistic number for transcripts and admissions.
- The simple proportional formula (used by some credential evaluators). GPA = (percentage ÷ 100) × scale max. So 85% becomes 0.85 × 4 = 3.4 on a 4.0 scale. International students — especially those converting an Indian, Pakistani, or European percentage for study abroad — often see this method on evaluator sites like WES.
The calculator above shows both so you can compare. If a specific university or evaluator publishes its own conversion table, always use that instead — these are planning estimates, not official figures.
Standard Percentage to GPA Table (4.0 Scale)
| Percentage | Letter grade | GPA |
|---|---|---|
| 97–100 | A+ | 4.0 |
| 93–96 | A | 4.0 |
| 90–92 | A− | 3.7 |
| 87–89 | B+ | 3.3 |
| 83–86 | B | 3.0 |
| 80–82 | B− | 2.7 |
| 77–79 | C+ | 2.3 |
| 73–76 | C | 2.0 |
| 70–72 | C− | 1.7 |
| 67–69 | D+ | 1.3 |
| 65–66 | D | 1.0 |
| Below 65 | F | 0.0 |
This is the most widely used US unweighted scale (the same one behind the College Board's 4.0 conversion). On an unweighted scale, A+ and A both equal 4.0. Some schools shift the cutoffs slightly (for example, an F below 60), so check your school's grade scale if it publishes one.
The Simple Percentage to GPA Formula
When you need a single proportional number — the method many study-abroad credential evaluators use — the formula is:
GPA = (Percentage ÷ 100) × Scale maximum
So on a 4.0 scale:
- 90% → 0.90 × 4 = 3.6
- 80% → 0.80 × 4 = 3.2
- 75% → 0.75 × 4 = 3.0
- 60% → 0.60 × 4 = 2.4
For a 5.0 scale multiply by 5; for a 10.0 scale (common in India) multiply by 10, which is why an Indian percentage is often roughly your CGPA × 9.5 in reverse. The calculator above runs all three automatically.
How to Calculate GPA from Percentage (Step by Step)
- Decide which method you need. For a US transcript or US admissions, use the letter-grade table. For a credential evaluation or a quick international estimate, use the proportional formula.
- Find your percentage. Use your overall percentage (a single course) or your average percentage across courses, weighted by credit hours if they differ.
- Map it with the table — locate your percentage band and read off the GPA (e.g. 88% falls in 87–89, so B+ = 3.3).
- Or apply the formula — divide your percentage by 100 and multiply by the scale max (88 ÷ 100 × 4 = 3.52).
- Average multiple courses by converting each course's percentage to GPA, multiplying by its credits, adding them up, and dividing by total credits.
Common Percentage-to-GPA Mistakes
- Assuming the proportional number is your real GPA. 85% is a B (3.0) on a US transcript, even though 0.85 × 4 = 3.4. Don't report the higher proportional figure to a US school.
- Averaging percentages without credits. A 4-credit course should move your GPA more than a 1-credit one — weight each course by its credit hours.
- Ignoring your school's own table. If your university publishes a percentage-to-letter scale, it overrides any generic conversion.
- Forgetting A+ caps at 4.0. On most unweighted scales there's no 4.3 — both A and A+ are 4.0.
- Mixing scales. Don't convert an Indian 10-point CGPA as if it were a percentage; convert the percentage, or use a dedicated CGPA-to-percentage tool.
Frequently Asked Questions
How do I calculate GPA from a percentage?
Two ways. The standard US method maps your percentage to a letter grade and then to a GPA (e.g. 85% = B = 3.0). The proportional method uses GPA = (percentage ÷ 100) × 4, so 85% = 3.4. Use the letter-grade method for US transcripts and the proportional one for credential evaluations.
What GPA is 90 percent?
On the standard US scale, 90% is an A− = 3.7 (and 93%+ is an A = 4.0). With the simple proportional formula, 90% = 0.90 × 4 = 3.6 on a 4.0 scale.
What GPA is 80 percent?
On the standard US scale, 80% is a B− = 2.7. With the proportional formula it's 0.80 × 4 = 3.2. The difference is why you should match the method to your purpose.
Is there an official percentage-to-GPA formula?
No single global standard exists. US schools convert through letter grades; credential evaluators often use proportional math. Always use a specific university's or evaluator's published table when one is available.
How do I convert a percentage to a 5.0 or 10.0 GPA?
Multiply by the scale maximum: GPA = (percentage ÷ 100) × 5 for a 5.0 scale, or × 10 for a 10.0 scale. The calculator above shows the 4.0, 5.0, and 10.0 results at once.
How do I turn several course percentages into one GPA?
Convert each course's percentage to a GPA, multiply by that course's credit hours, add the results, then divide by total credit hours. That gives a credit-weighted GPA rather than a plain average.
