Percentage to GPA Converter
Convert any percentage grade to GPA on the 4.0 or 4.3 scale. Calculate your cumulative GPA from percentage grades across multiple courses.
Different schools report grades differently — some use letter grades, others use percentages. This converter translates any percentage grade into its GPA equivalent on either the standard 4.0 or 4.3 scale, with a full conversion table for reference. You can also calculate your cumulative GPA directly from percentage grades across all your courses.
Percentage to GPA Conversion Table (4.0 scale)

How to Use the Percentage to GPA Converter
- 1Choose "Single Grade" to convert one percentage, or "Multiple Courses" to calculate your cumulative GPA.
- 2Select your GPA scale — 4.0 (most US colleges) or 4.3 (some high schools and Canadian institutions).
- 3For a single grade: type your percentage and your GPA and letter grade appear instantly.
- 4For multiple courses: enter the percentage grade and credit hours for each course, then click "Calculate GPA".
- 5Use the reference table at the bottom to see the full conversion chart for your selected scale.
Worked Example: Converting a Single Percentage
Take an 88% — a typical B+ paper grade. The converter checks which bracket 88 falls into: 87–89% maps to a B+, and a B+ is worth 3.3 on both the 4.0 and 4.3 scales (they only diverge at A+). So 88% → B+ → 3.3 GPA. The two scales share every bucket except the very top one, which is why most students never notice a difference unless they're earning A+ grades.
Worked Example: Cumulative GPA from Percentage Grades
Three 3-credit courses, graded by percentage instead of letter grade:
| Percentage | Letter | GPA Points | Credits | Grade Points |
|---|---|---|---|---|
| 85% | B | 3.0 | 3 | 9.0 |
| 92% | A- | 3.7 | 3 | 11.1 |
| 76% | C | 2.0 | 3 | 6.0 |
| Total | 9 | 26.1 |
GPA = 26.1 ÷ 9 = 2.90. Notice each course is converted to its letter-grade GPA point value first, then weighted by credits — the raw percentages themselves (85, 92, 76) are never averaged directly.
Why 89.9% Isn’t Automatically an A-
Conversion scales genuinely vary between institutions — some use a straight 90/80/70/60 cutoff with no plus/minus grades, others shift breakpoints by a point or two. This tool uses the standard 13-step scale shown in the table below, the same one most US colleges publish in their catalogs. One detail worth knowing: the converter truncates rather than rounds. An 89.9% is floored to 89% before the lookup, which lands it in the 87–89% B+ bracket (3.3 GPA) — not the 90–92% A- bracket (3.7 GPA) you might expect if you mentally rounded up. This matches how most registrars actually compute letter grades from recorded percentages, but it means a grade that "feels" like a 90 can convert a full third of a GPA point lower than expected. If your school rounds instead of truncates, check your syllabus — the gap right at each boundary is exactly where policies differ most.

Frequently Asked Questions
How do I convert a percentage to GPA?
Look up your percentage in the standard grading scale to find your letter grade, then map that letter grade to a GPA point value. For example, 88% = B+ = 3.3 GPA on a 4.0 scale. Our converter does this instantly — just type your percentage.
What is the difference between a 4.0 and 4.3 GPA scale?
On the 4.0 scale, A and A+ both equal 4.0. On the 4.3 scale, A+ is worth 4.3, allowing students who earn A+ grades to exceed a 4.0 GPA. Most US colleges use the 4.0 scale, while some high schools and Canadian institutions use 4.3.
Is 85% a good GPA?
85% converts to a B (3.0 on a 4.0 scale), which is considered good academic standing. A 3.0 GPA generally meets the minimum for most graduate school applications and scholarship requirements.
What percentage is a 3.5 GPA?
A 3.5 GPA falls between B+ (3.3, roughly 87–89%) and A- (3.7, roughly 90–92%). There is no single exact percentage for 3.5 since GPA uses discrete letter grade buckets, but it generally corresponds to high B+ performance.
Can I calculate my overall GPA from percentage grades?
Yes — use the "Multiple Courses" tab. Enter your percentage grade and credit hours for each course and click Calculate GPA. The tool converts each percentage to a GPA point value, then computes your weighted cumulative GPA.
What percentage is a passing grade?
In most US institutions, 60% (D-) is the minimum passing grade, equivalent to 0.7 GPA. However, many programs require a C (73%, 2.0 GPA) or higher in major courses. Check your institution's academic requirements.
