2026 GPA scale: summary table
Every letter grade below carries a fixed 4.0-scale point value and a typical percentage range. This is the same lookup table used inside the GPA to percentage calculator and the grade dropdowns on the GPA calculator, so the numbers on this page and the numbers your calculator returns will always match.
| Letter Grade | GPA Points (4.0 scale) | Percentage Range |
|---|---|---|
| A+ | 4.0 | 97 to 100% |
| A | 4.0 | 93 to 96% |
| A- | 3.7 | 90 to 92% |
| B+ | 3.3 | 87 to 89% |
| B | 3.0 | 83 to 86% |
| B- | 2.7 | 80 to 82% |
| C+ | 2.3 | 77 to 79% |
| C | 2.0 | 73 to 76% |
| C- | 1.7 | 70 to 72% |
| D+ | 1.3 | 67 to 69% |
| D | 1.0 | 63 to 66% |
| D- | 0.7 | 60 to 62% |
| F | 0.0 | 0 to 59% |

What is the standard 4.0 GPA scale?
The standard 4.0 GPA scale is the most common grading system at US high schools and colleges. It assigns every letter grade a fixed number of grade points, with A worth the maximum of 4.0 and F worth zero. Schools that use plus and minus grades typically space the points 0.3 to 0.4 apart: an A- is 3.7, a B+ is 3.3, a C is 2.0, and so on down to a D- at 0.7. Each letter grade also lines up with a percentage range, though individual schools set their own cutoffs. The table on this page uses the same scale that powers the GPACalcTools GPA calculator and GPA to percentage converter, reflecting the percentage ranges most commonly used across US institutions in 2026. If your school treats any score above 90 percent as a flat 4.0 rather than an A-, adjust your reading of the table accordingly.
Methodology: where these numbers come from
This table is not survey data or a third-party average. It is the literal lookup table built into GPACalcTools' own grade-conversion tools: the same grade-to-point values that populate the dropdown menus on the GPA calculator, and the same percentage bands used by the reverse-conversion logic on the GPA to percentage calculator. Both tools compute results in the visitor's browser using this exact scale, so the reference table above is guaranteed to match what those calculators produce.
The scale itself is the common unweighted US 4.0 system used by the large majority of high schools and colleges: A/A+ at the top, F at the bottom, with plus and minus grades filling in intermediate steps. It is not a proprietary formula and it is not survey-derived; it is the standard convention this site's calculators are built on. Individual schools vary in exactly where they draw each percentage cutoff, which is why the table gives ranges rather than single hard lines. This page was last checked and updated July 2, 2026, and will be refreshed if GPACalcTools' underlying calculator scale changes.
How to use this table
Match your percentage or letter grade to the corresponding row to find its 4.0-scale point value, or go the other direction to see the typical percentage band for a given GPA. To convert a full transcript rather than a single grade, use the GPA calculator, which applies this same scale automatically across every course you enter, weighted by credit hours.
