How does percentage map to GPA?

It uses the common US table: 93–100% is 4.0 (A), 90–92% is 3.7 (A−), 83–86% is 3.0 (B), and so on down to below 60% which is 0.0 (F).

Percentage to GPA

Enter a percentage grade and this tool converts it to a GPA on the 4.0 scale along with the matching letter grade. It is handy for students translating a course mark, comparing grades across systems, or estimating a GPA for applications that expect the US scale.

How it works

The converter clamps your input to 0–100, then finds the band it falls into and returns that band’s GPA point and letter:

PercentageLetterGPA
93–100A4.0
90–92A−3.7
87–89B+3.3
83–86B3.0
80–82B−2.7
77–79C+2.3
73–76C2.0
70–72C−1.7
67–69D+1.3
63–66D1.0
60–62D−0.7
Below 60F0.0

Example

A grade of 88% falls in the 87–89 band, which maps to B+ and a GPA of 3.3. A 95% maps to A / 4.0, and a 71% maps to C− / 1.7.

This is the widely cited College Board style table; some institutions use slightly different cut-offs, so check your own scale if it differs. The conversion happens entirely in your browser and nothing leaves your device.

Converting a whole transcript to a cumulative GPA

This tool converts one grade at a time. To calculate a semester or year GPA from multiple courses, convert each percentage to its GPA point, then take a credit-weighted average:

cumulative GPA = Σ (GPA point × credit hours) ÷ Σ credit hours

For example, three courses — 91% worth 3 credits (3.7), 85% worth 4 credits (3.0), and 78% worth 2 credits (2.3) — give:

(3.7 × 3) + (3.0 × 4) + (2.3 × 2) = 11.1 + 12.0 + 4.6 = 27.7
27.7 ÷ (3 + 4 + 2) = 27.7 ÷ 9 = 3.08

The cumulative GPA is 3.08 — a B on the 4.0 scale.

Why grading scales differ between institutions

The 12-step table used here is the most widely published US reference, but institutions legitimately differ in a few ways:

  • 10-point vs 7-point bands. Some schools use a simpler 10-point banding where 90–100 = A and 80–89 = B, with no plus or minus modifiers. On that scale an 88% is a flat B (3.0), not a B+ (3.3).
  • Weighted honours GPA. AP, IB, and honours courses sometimes add 0.5 or 1.0 to the GPA point, allowing scores above 4.0. This tool shows the unweighted value; your school may weight differently.
  • International grading. UK percentage grades use a different distribution — a 70% at a UK university is typically a First-class result, not equivalent to a C as the US table would suggest. When converting for a US graduate school application, include a note on the scale used.

Always check the specific grading policy of the institution whose GPA you are computing or reporting.
