What is GPA Calculator?
A GPA (Grade Point Average) calculator converts your course grades and credit hours into a single weighted average that represents your overall academic performance. On the US 4.0 scale, each letter grade maps to a numeric value: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Each course's grade value is multiplied by its credit hours, and the sum is divided by the total credits — giving more weight to courses with more credits. This calculator also supports the Portuguese and Brazilian 0–20 scale and the Spanish and Latin American 0–10 scale, so international students can calculate their GPA in the system that is most relevant to their academic institution.
How to use
- Select your grading scale (US 4.0, Portugal/Brazil 0–20, or Spain/Latin America 0–10).
- Enter each course name (optional), grade, and credit hours in the course rows.
- Click 'Add Course' to add more rows as needed.
- Click 'Calculate GPA' to see your weighted GPA and total credits.
- Use the Cumulative GPA tab to combine your current GPA record with a new semester's results.
Why it matters
GPA is one of the most consequential numbers in a student's academic life. Most universities require a minimum GPA — often 2.0 — to remain in good standing, and many programmes require 3.0 or higher for continued enrollment. Scholarship committees, graduate school admissions panels, and many employers use GPA as a screening criterion. On the US 4.0 scale, a GPA above 3.5 is widely considered excellent and is a common threshold for honours distinctions, Dean's List recognition, and competitive graduate programme applications. Understanding exactly where you stand — and how each course affects your overall average — empowers you to make strategic decisions about your workload and study focus.
Pro tip
Because GPA is credit-weighted, high-credit courses have an outsized impact on your average. If you are struggling in a 4-credit course graded A–F, that course affects your GPA twice as much as a 2-credit elective. Prioritise your study time accordingly — protecting your grade in high-credit core courses is the most efficient way to maintain or raise your GPA.
Convert Brazilian Grades (0–10 / 0–100) to a 4.0 GPA
Brazilian transcripts report grades on a 0–10 scale, or 0–100 in secondary school, while US applications ask for a number between 0.0 and 4.0. No single official conversion exists, but the band table below is the mapping most widely used to estimate a GPA, and it is what this calculator applies when you select a 0–10 scale.
| Grade (0–10) | Grade (0–100) | US letter | GPA (4.0) |
|---|---|---|---|
| 9.5 - 10.0 | 95 - 100 | A | 4.0 |
| 8.5 - 9.4 | 85 - 94 | A− | 3.7 |
| 7.5 - 8.4 | 75 - 84 | B+ | 3.3 |
| 6.5 - 7.4 | 65 - 74 | B | 3.0 |
| 6.0 - 6.4 | 60 - 64 | B− | 2.7 |
| 5.5 - 5.9 | 55 - 59 | C+ | 2.3 |
| 5.0 - 5.4 | 50 - 54 | C | 2.0 |
| below 5.0 | below 50 | F | 0.0 |
This table is an estimate, not an official conversion. US universities usually require an evaluation from a credential service such as WES, ECE or SpanTran, and each evaluator applies its own methodology. Use this table to plan where to apply; use the evaluator’s report to actually apply.
Worked example
A semester of Calculus II 7.2 (6 credits), Physics II 6.3 (4), Linear Algebra 8.7 (4), Programming 9.6 (4) and Research Methods 8.0 (2) converts to 3.0, 2.7, 3.7, 4.0 and 3.3 grade points. Weighted by credits that is (3.0×6) + (2.7×4) + (3.7×4) + (4.0×4) + (3.3×2) = 66.2 points across 20 credits, a GPA of 3.31. Note that an arithmetic average of 7.96 in Brazil becomes a 3.31 GPA, because the conversion is not linear.
