Short answer. A 3.4 GPA is about 89% on the common US 4.0 scale. That is between a B+ (3.3) and an A- (3.7). Schools set their own bands, so check yours.
What a 3.4 GPA is in percent
A 3.4 sits in the B range. Most of your grades are Bs, with some higher and some lower.
On the common US plus and minus scale, a 3.4 GPA falls between a B+ (3.3) and an A- (3.7). The B+ band is 87% to 89% and the A- band is 90% to 92%. A straight-line estimate between the middles of the two bands gives about 89%. The nearest single letter is B+.
How other methods convert 3.4
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) | about 89% | The usual US bands, with a straight-line estimate between letters. |
| 10-point scale, no plus or minus | about 89% | 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) | 85.0% | Quick, but not a real grading scale. It runs low for most GPAs. |
The three methods give results from 85% to 89% for the same 3.4. 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 3.4
For example, 2 courses at A- and 8 at B+ (all with the same credits) average 3.38, which rounds to about 3.4. 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 3.4. If your 3.4 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
The jump from a B record to a B+ record usually comes from one or two subjects. Find the classes that pull you down and give them more time.

Worked example
Example. Your transcript shows a 3.4 cumulative GPA and a form asks for a percent. On the plus and minus scale, write about 89%. If the form names a different scale, use that scale instead.
