Percentage to GPA Converter

Converting a percentage takes two quick entries. The tool matches your percentage to a letter grade band, then reads off the grade points for that band.

1. Enter your percentage grade, from 0 to 100, in the first field.
2. Pick your grading system. US 4.0 with plus/minus is the default, and it is the scale most US schools use.
3. Press Calculate, or press Enter. Your GPA appears first and large, with the letter grade, the percentage band and the result on the other scale below. Press Reset to clear the form and start over.

US schools convert percentages through letter grades, not through arithmetic. Your percentage first maps to a letter grade band, and the letter grade then maps to fixed grade points. The standard plus/minus bands are 97 to 100% for A+, 93 to 96% for A, 90 to 92% for A-, 87 to 89% for B+, 83 to 86% for B, 80 to 82% for B-, 77 to 79% for C+, 73 to 76% for C, 70 to 72% for C-, 67 to 69% for D+, 63 to 66% for D, 60 to 62% for D-, and below 60% for F.

The grade points for those letters on the 4.0 plus/minus scale are A+ 4.0, 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+ 1.3, D 1.0, D- 0.7, and F 0.0. Because whole bands of percentages map to one GPA value, the conversion only runs one way. A 3.0 GPA could come from any percentage from 83% to 86%, so you cannot turn a GPA back into an exact percentage. Our GPA calculator works the other way round, from letter grades to a term GPA.

A student scores 85% and wants the GPA on the US 4.0 scale with plus/minus. Here is exactly what the calculator does.

1. Find the band: 85% falls in the 83 to 86% band, which is a B.
2. Read the grade points: a B is worth 3.0 on the 4.0 plus/minus scale.
3. Answer: 85% converts to a GPA of 3.0.

On the other scales the same 85% gives different answers. On the standard 4.0 scale without plus/minus, 85% is also a B, worth 3.0. On the proportional scale, 85 divided by 25 is 3.4. The band result of 3.0 is the one US schools and admissions offices use, which is why this tool defaults to the plus/minus scale. Try your own percentage in the tool above.

The four scales in this tool answer the same question four ways, and they disagree most in the middle of the range. The table below shows the same percentages on each scale.

The plus/minus and 4.3 scales only differ at A+, where the 4.3 scale gives 4.3 instead of 4.0. The standard scale drops the plus and minus letters, so 91% is a full A worth 4.0 on it, but only 3.7 on the plus/minus scale. The proportional scale is a shortcut, not a school rule, and it overstates most grades. Always state which scale you used.

Dividing by 25 looks tidy, but no US school converts that way. A school sets percentage cutoffs for each letter, and the letter carries fixed points, so two students a few points apart can land in the same band, while two students one point apart can land in different bands. An 89% is a B+ worth 3.3, and a 90% is an A- worth 3.7, so one point moves the GPA by 0.4.

The divide by 25 shortcut hides that cliff. It gives 89% a GPA of 3.56 and 90% a GPA of 3.6, which looks smooth but matches no transcript. Credential evaluators such as WES use country-specific band tables for the same reason. Use the band method for anything official, and treat the proportional scale only as a rough sense of where a percentage sits. Our CGPA calculator and CGPA to percentage converter cover the 10-point scale used in India, where the conversion works differently.

Grading legends are set school by school, so the bands on this page are the most common US convention, not a universal law. Before you put a converted GPA on an application, check your own school transcript legend or your target university published scale. Some schools start A at 90 instead of 93, some cap A+ at 4.0, and some use no plus or minus grades at all.

If your school reports percentages only, ask the registrar for its conversion table, since that table is the one an admissions office will trust. Keep the percentage next to the GPA on any form that asks for both, and note the scale in words, for example 3.0 on a 4.0 plus/minus scale. Our percentage calculator and final grade calculator help with the percentage maths and the grade you need on a final exam.
