Taiwan GPA Calculator: NTU 4.3 Scale to US 4.0

How the Taiwan GPA Calculator Works (NTU 4.3 Scale, Letter and Percentage Modes)

The Taiwan GPA calculator above runs a two-mode credit-weighted average on the 4.3 ceiling scale published by National Taiwan University (NTU) and adopted by the other research universities (NTHU, NCKU, NYCU, NCCU, NTUST). Pick Letter mode if your transcript reports letter grades (A+, A, A-, B+, B, B-, C+, C, C-, D, F); pick Percentage mode if your transcript reports raw 0 to 100 marks. The calculator maps each percentage to its letter band, then to the grade-point value, and produces the cumulative GPA.

The math is identical across modes: each course earns grade points equal to its letter value, those points are multiplied by the credit hours, the products are summed across all completed courses, and the total is divided by total credit hours to produce the cumulative GPA. The result panel shows your CGPA on the Taiwan 4.3 scale, the matching letter band with both the English label (Excellent, Good, Average, Pass, Marginal, Fail) and the Chinese standing class (You Deng, Jia Deng, Yi Deng, Bing Deng, Ding Deng, Bu Ji Ge), the US 4.0 equivalent for North American graduate applications, and a scholarship-threshold marker for Taiwan Scholarship and university merit awards.

This is a college GPA calculator for Taiwanese universities, a grade calculator for NTU and the other national research universities, and a final exam grade calculator when you enter the term marks. What does GPA stand for? Grade Point Average, the cumulative credit-weighted academic metric used worldwide; in Mandarin Chinese it is rendered as GPA or 學業平均成績 (xueye pingjun chengji, academic average score) on the local-market search results, with 美國 GPA 換算 (US GPA conversion) being a high-intent local query that this calculator directly answers.

Taiwan University Grading Scale: Letters, Percentage Bands, and Grade Points

Taiwanese university grading follows the National Taiwan University reference table. Every accredited research university uses the same eleven-letter system tied to the same percentage cut-offs and the same grade-point values; the Ministry of Education (MOE) does not override institutional policy on the percentage table but accredits universities that adopt the NTU framework.

Two details matter for accuracy. First, the percentage cut-offs are strict at every band line; a student earning 84.99 percent receives A- (3.7), not A (4.0), with no rounding-up policy at most national universities. Second, the 60 percent line is the undergraduate pass threshold; below 60 the credit is not awarded. The graduate threshold sits higher: a B- (2.7, 70 to 72 percent) is the lowest graduate passing grade at NTU and NTHU, so C+ and below earn zero credit for graduate students even though the same grade earns 2.3 points for an undergraduate. The 3.0 GPA, 3.7 GPA, and 4.0 GPA threshold lines are the most-searched anchor points in the Taiwan cluster.

How Is GPA Calculated in Taiwan: The Credit-Weighted Average Formula

Taiwanese universities apply the credit-weighted average formula used internationally. The numerator sums the products of grade points and credit hours across every graded course; the denominator sums the credit hours across the same courses.

Worked example: an NTU student takes Calculus II (3 cr, A = 4.0), Microeconomics (3 cr, A- = 3.7), Modern Taiwanese History (2 cr, A+ = 4.3), English Composition (1 cr, B+ = 3.3), and Physics Lab (1 cr, A = 4.0). Quality points: 4.0 x 3 + 3.7 x 3 + 4.3 x 2 + 3.3 x 1 + 4.0 x 1 = 12 + 11.1 + 8.6 + 3.3 + 4 = 39. Total credits: 10. Semester GPA = 39 / 10 = 3.90 (You Deng / Excellent standing). On the US 4.0 scale this converts to (3.90 / 4.3) x 4.0 = 3.63, comfortably above the typical US graduate school threshold of 3.0.

Second worked example for the percentage mode: an NCKU engineering student records raw marks of 92, 88, 76, 65, and 58 across five three-credit courses. Letter mapping: 92 to A+ (4.3), 88 to A (4.0), 76 to B (3.0), 65 to C (2.0), 58 to F (0.0). Quality points: 4.3 x 3 + 4.0 x 3 + 3.0 x 3 + 2.0 x 3 + 0.0 x 3 = 12.9 + 12 + 9 + 6 + 0 = 39.9. Total credits: 15. Semester GPA = 39.9 / 15 = 2.66 (Yi Deng / Average standing). The 58 percent mark in the final course converts to F under the strict NTU table, dragging the semester average below the 3.0 line.

Major Taiwanese Universities and Their Grading Policies

Below are the major Taiwanese research universities accredited by the Ministry of Education (MOE). All listed institutions use the NTU 4.3 letter scale documented above; the only institutional differences are in graduate-school cut-offs for academic probation and in class-rank caps on A+ awards at selective professional schools.

National Taiwan University (NTU): The Reference Scale

National Taiwan University in Taipei is the most internationally recognized university in Taiwan and ranks consistently among the top 100 globally in multiple subject areas. The NTU Office of Academic Affairs publishes the canonical Taiwan letter scale in its Academic Grading Guide. Undergraduate courses pass at D (1.0); graduate courses pass at B- (2.7). Some NTU schools (Law, Medicine) cap A+ awards at the top 5 to 10 percent of the class rank, so a 92 percent raw mark may map to A rather than A+ depending on cohort distribution. Always check the department handbook.

NTHU, NCKU, NYCU: The Same Scale, Same Cut-Offs

National Tsing Hua University (Hsinchu), National Cheng Kung University (Tainan), and National Yang Ming Chiao Tung University (Hsinchu and Taipei) all adopt the NTU table with identical percentage cut-offs. NCKU is the largest by enrolment and concentrates in engineering and medicine; NYCU formed in 2021 from the merger of National Chiao Tung and National Yang Ming and is the strongest combined IT-and-medicine campus in Taiwan. All three universities apply the 60 percent line as the undergraduate pass threshold and the 70 percent line as the graduate pass threshold.

NCCU, NTUST, and Specialised Universities

National Chengchi University (NCCU) in Taipei concentrates in law, political science, business, and humanities; National Taiwan University of Science and Technology (NTUST) is the leading technical university in Taipei with strong engineering and design programs. Both follow the NTU 4.3 letter table without modification. National Taiwan Normal University (NTNU) is the country's leading teacher-training institution and applies the same scale. Private universities including Fu Jen Catholic University, Soochow University, and Tunghai University also use the NTU letter framework, with minor variation in the 90 to 100 percent cap (some private universities issue A+ only at the 95 percent line rather than 90).

Convert Taiwan GPA to US 4.0 GPA for Graduate School

Taiwanese university graduates applying to US graduate programs need their CGPA expressed on the US 4.0 scale because the Common App, the Coalition Application, and most US graduate school forms expect a 4.0 ceiling. The linear conversion is US 4.0 GPA = (Taiwan 4.3 GPA / 4.3) x 4.0, capped at 4.0.

For binding US graduate school applications, World Education Services (WES) generates an authoritative course-by-course US GPA from Taiwanese transcripts (cost roughly USD 230 in 2026). Educational Credential Evaluators (ECE) and Scholaro are common alternatives accepted at most US graduate programs. The calculator above is for planning purposes; for binding applications a WES report is the canonical source. Reverse questions, including 美國 GPA 換算 (US GPA conversion) from a home Taiwanese transcript, are answered directly by the calculator output.

Taiwan Scholarship and University Merit Award Thresholds

The Ministry of Education (MOE) Taiwan Scholarship and the Huayu Enrichment Scholarship are the two main government-funded awards for international students at Taiwanese universities. Both apply minimum GPA thresholds.

The Taiwan Scholarship is the flagship MOE award and covers monthly stipend, tuition, and travel for selected international students. Most awarded applicants present a transcript averaging 3.7 or higher on the Taiwan 4.3 scale, which is the You Deng band. The Huayu Enrichment Scholarship covers Mandarin study at MOE-accredited language centres and is more accessible at the 3.0 threshold. NSTC (National Science and Technology Council) research fellowships evaluate publications and supervisor reference alongside the home GPA.

What Counts as a Good GPA at Taiwanese Universities

Taiwanese academic standing thresholds follow the You Deng, Jia Deng, Yi Deng, Bing Deng, Ding Deng, Bu Ji Ge classification system on the 4.3 scale:

• You Deng (Excellent) standing: 3.7 or above on the 4.3 scale. Required for departmental commendations, Taiwan Scholarship renewal, and most national merit awards. NTU uses the term Sotsugyo Yushusha for top graduating seniors.
• Jia Deng (Good) standing: 3.0 to 3.69 on the 4.3 scale. Typical range for the upper half of a competitive research university cohort. Sufficient for most graduate school admissions in Taiwan and as a baseline for US graduate applications.
• Yi Deng (Average) standing: 2.0 to 2.99 on the 4.3 scale. Above the graduation minimum at virtually every Taiwanese university; below the typical graduate school competitive threshold.
• Probation threshold: below 1.7 (4.3 scale) at most national universities, with one or two semesters to recover before a formal warning.
• Graduation minimum: typically 2.0 on the 4.3 scale plus the required credit hours (128 for undergraduate at NTU, 24 to 30 for a masters depending on program).

For graduate school applications, a 3.3 on the Taiwan 4.3 scale (about 3.07 US) is competitive for most national university masters programs; 3.7 or above (about 3.44 US) for top-tier programs at NTU, NTHU, NCKU, and NYCU. International applicants to the Taiwan Scholarship program should aim for 3.7 / 4.3 to stay above the published threshold. Class rank matters at selective professional schools at NTU; check the department handbook for class-rank-capped A+ rules before assuming raw percentage translates one-to-one to letter.
