Short answer. A 4.0 GPA is 93% to 100% on the common US 4.0 scale. That is an A. Schools set their own bands, so check yours.
What a 4.0 GPA is in percent
A 4.0 is near the top of the 4.0 scale. Almost all of your grades are As.
On the common US plus and minus scale, a 4.0 GPA matches an A. That letter covers 93% to 100%, with a middle of about 96%.
How other methods convert 4.0
There is no single official way to turn a GPA into a percentage. These are the methods you will see most often.
| Method | Result | Notes |
|---|---|---|
| Plus and minus scale (used on this site) | 93 to 100% | The usual US bands, with a straight-line estimate between letters. |
| 10-point scale, no plus or minus | about 95% | A is 90 to 100, B is 80 to 89 and so on. Uses the middle of each band. |
| Simple proportion (GPA / 4 x 100) | 100.0% | Quick, but not a real grading scale. It runs low for most GPAs. |
The three methods give results from 95% to 100% for the same 4.0. The gap is small at this level, so most readers will see a similar number. If a school or employer asks for a percentage, use the conversion your own school prints on its transcript or grading policy.
What grades give a 4.0
Every course at A gives exactly 4.0. Credits change the weight of each course, so a 4-credit class moves the average more than a 1-credit class.
These figures assume an unweighted 4.0. If your 4.0 is a weighted GPA that includes honors or AP points, the unweighted number behind it is lower, and so is the percent. Convert the unweighted GPA when a form asks for a percentage.
Next steps
There is little room to go up, so the aim is to hold this level. A single C in a heavy course can cost more than you might expect.

Worked example
Example. Your transcript shows a 4.0 cumulative GPA and a form asks for a percent. On the plus and minus scale, write 93% to 100%. If the form names a different scale, use that scale instead.
