GPA calculator from percentage
This percentage GPA calculator converts numeric percentage grades (0–100) to letter grades and then to GPA points on the 4.0 scale. Enter each course's percentage score and credit hours - the letter grade equivalent appears beside each course and your final credit-weighted GPA calculates automatically.

What Is a GPA Calculator from Percentage?
A GPA calculator from percentage converts numeric percentage scores to letter grades and then to grade point values on the 4.0 scale, allowing students who receive percentage grades to estimate their GPA.
- Converts percentage scores (0–100%) to letter grades using standard grade boundaries
- Maps letter grades to grade point values on the 4.0 scale
- Useful for international students and courses reported in percentage format
- Provides a GPA estimate - exact conversion may vary by institution's grade scale
- Supports weighted averaging by credit hours once grade points are assigned
Many countries and some US programs report grades as percentage scores rather than letter grades. Converting percentage to GPA requires two steps: first, the percentage maps to a letter grade using the school's grade boundaries; second, the letter grade maps to a grade point value on the 4.0 scale. Standard US boundaries (90%=A, 80%=B, etc.) are used as a default, but students should verify their school's exact boundaries before converting for official purposes.
How to Convert Percentage Grades to GPA?
Record the percentage score for each course
Gather the numeric percentage from the grade report or learning management system.
Convert each percentage to a letter grade
Use the standard scale: 93%+=A, 90–92%=A-, 87–89%=B+, 83–86%=B, 80–82%=B-, 77–79%=C+, 73–76%=C, 70–72%=C-, 60–69%=D, <60%=F.
Map the letter grade to grade points
A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D=1.0, F=0.0.
Multiply grade points by credit hours
Quality points per course = grade point value × credit hours.
Divide for GPA
Total quality points ÷ total credit hours = GPA on the 4.0 scale.
Worked Example
Percentages: 91% → A- (3.7, 3cr), 84% → B (3.0, 4cr), 88% → B+ (3.3, 3cr). GPA = (11.1+12+9.9) ÷ 10 = 3.30.

GPA calculator from percentage - Specialized GPA Systems
While the standard 4.0 scale is universal in the US, certain institutions and programs use specialized GPA calculations. Understanding these variations is critical for law school (LSAC), University of California system, or medical school (AMCAS) applicants.
LSAC GPA (Law School)
The Law School Admission Council (LSAC) calculates its own GPA for law school applicants. This LSAC GPA often differs from the school-reported GPA for several reasons:
- LSAC counts all undergraduate coursework, including transfer credits the school may have excluded
- Courses taken at multiple institutions are all included
- LSAC uses its own grade conversion table, which may differ from the school's
- Repeated courses: LSAC counts both the original and repeated grade, not just the better one
Full details on LSAC GPA methodology are available at lsac.org.
UC System GPA
The University of California system recalculates GPA from 10th and 11th grade a-g courses:
- Only a-g courses count (English, Math, Lab Science, Foreign Language, History, Elective, Visual/Performing Arts)
- Extra weight for up to 8 semesters of UC-approved Honors/AP/IB courses (+1.0 bonus per grade)
- 9th and 12th grade courses are not included in the UC GPA calculation
- Maximum honors points capped to prevent inflation

Specialized GPA Requirements by Program
| Purpose | Minimum GPA | Notes |
|---|---|---|
| Law School (LSAC GPA) | 3.5+ | Median LSAC GPA for admitted students at top-14 law schools is 3.7–3.9. LSAC includes all undergraduate courses. |
| Medical School (AMCAS) | 3.5+ | AMCAS calculates overall GPA and a separate science GPA (BCPM: Biology, Chemistry, Physics, Math). |
| UC System Admission | 3.0 (weighted) | UC calculates a capped and uncapped weighted GPA from 10th–11th grade a-g courses only. |
| Science GPA (pre-med) | 3.5+ | Medical schools evaluate science GPA separately. A low science GPA below 3.2 significantly reduces admission chances. |
| GPA Without Credit Hours | Varies | When courses have no credit value, use 1 credit per course for an equal-weight average. This calculator supports no-credit calculations. |
| GPA from Percentage Score | Varies | Convert percentage to letter grade first, then to grade points. 90%+ = A = 4.0, 80–89% = B = 3.0, etc. |
Common Mistakes With Specialized GPA Calculations
Assuming LSAC GPA equals the school-reported GPA
Problem: LSAC includes all undergraduate courses (repeated courses both counted, all institutions combined). The LSAC GPA is often lower than the school-reported GPA.
Fix: Calculate LSAC GPA early in the application process by entering all undergraduate coursework from all institutions, including repeated courses with both grades.
Not calculating science GPA separately for medical school
Problem: Medical school applicants who only track overall GPA miss the BCPM (Biology, Chemistry, Physics, Math) science GPA, which is evaluated independently by AMCAS.
Fix: Enter only BCPM-classified courses into a separate calculator session to compute science GPA. Track it alongside overall GPA from sophomore year onward.
Including 9th or 12th grade courses in UC GPA calculation
Problem: The UC system uses only 10th and 11th grade a-g courses. Including 9th or 12th grade courses produces an incorrect UC GPA.
Fix: List only 10th and 11th grade a-g courses when calculating UC GPA. Apply the UC honors cap (maximum 8 semesters of bonus points).
Calculating GPA from percentage without using the correct conversion scale
Problem: Different institutions define letter grade cutoffs differently (some use 90% for A, others use 93%). Using the wrong conversion produces an inaccurate GPA.
Fix: Use the school's published grading scale for conversion. Most US schools: A = 90–100% or 93–100% depending on the policy. Apply the specific cutoffs from the institution's catalog.
