Weighted GPA adds the bonus of honors and AP/IB courses to every grade except an F. Cumulative GPA divides all quality points by all credits: it is not the average of the term GPAs.
What GPA do I need?

An estimate, not your official GPA
This calculator uses the standard formula and the scale below. Your school sets its own points, bonuses, rounding, and rules for repeated courses, transfer credits, and pass/fail grades. Check your transcript or registrar for the official number.Grading scale
There is no official GPA scale. These are the points most U.S. schools use on a 4.0 scale, with the percentages that usually go with each letter. The percentages are a typical chart, not a rule. Edit the points and bonuses to match your school: they are used in every calculation above.

|---|---|---|
| A+ | 97–100% | |
| A | 93–96% | |
| A- | 90–92% | |

Frequently asked questions
What is the 4.0 GPA scale?
A scale where an A is 4.0, a B is 3.0, a C is 2.0, a D is 1.0, and an F is 0. Plus and minus grades add or subtract 0.3 or 0.4 points, so an A- is 3.7 and a B+ is 3.3.
Is there an official GPA scale?
No. Schools, districts, and colleges set their own. The chart here is the most common convention, and the percentage ranges in particular vary from one school to another.
How do I convert a percentage to a GPA?
Find the letter for your percentage in your school’s grading policy, then use the points for that letter. With the typical ranges here, an 88% is a B+, which is 3.3.
The common 4.0 scale
Most U.S. high schools and colleges convert letters to points like this. The percentage ranges are typical, not official, and some schools do not use plus and minus grades or give an A+ 4.3 points.
| Letter | Typical percentage | Points | Honors points | AP or IB points |
|---|---|---|---|---|
| A+ | 97–100% | 4.0 | 4.5 | 5.0 |
| A | 93–96% | 4.0 | 4.5 | 5.0 |
| A- | 90–92% | 3.7 | 4.2 | 4.7 |
| B+ | 87–89% | 3.3 | 3.8 | 4.3 |
| B | 83–86% | 3.0 | 3.5 | 4.0 |
| B- | 80–82% | 2.7 | 3.2 | 3.7 |
| C+ | 77–79% | 2.3 | 2.8 | 3.3 |
| C | 73–76% | 2.0 | 2.5 | 3.0 |
| C- | 70–72% | 1.7 | 2.2 | 2.7 |
| D+ | 67–69% | 1.3 | 1.8 | 2.3 |
| D | 63–66% | 1.0 | 1.5 | 2.0 |
| D- | 60–62% | 0.7 | 1.2 | 1.7 |
| F | below 60% | 0.0 | 0.0 | 0.0 |
Honors points add 0.5 and AP or IB points add 1.0, the common bonuses; an F gets no bonus here. Both are editable in the GPA calculator.
What common GPAs mean
| GPA | Same as |
|---|---|
| 4.00 | All A’s |
| 3.50 | Half A’s and half B’s |
| 3.00 | All B’s |
| 2.50 | Half B’s and half C’s |
| 2.00 | All C’s |
| 1.00 | All D’s |
GPAs in between come from mixes of grades and credits. A 3.7, for example, is an A- average or a mix of A’s and B+’s.
Percentages are not the same everywhere
One school’s A starts at 93% and another’s at 90%. If your school publishes its scale, enter its points in the calculator. For averaging scores on other scales, see the grade calculator, and for turning scores into percentages, the percentage calculator.
