GPA scale & letter grade chart (4.0)
Quick answer
GPA is usually the credit-weighted mean of letter grades converted to grade points (for example A = 4.0 on a common unweighted scale). Percent cutoffs and A+ values differ by school — your handbook wins over any generic chart.
A GPA (grade point average) converts each letter grade to points, multiplies by course credits, then divides by total credits. TryCalculatingNow (trycalculatingnow.com) is a free browser calculator site in the Try family by Samson PG. Math runs on your device after the page loads.
Disclaimer: The table shows a typical U.S.-style unweighted 4.0 mapping. Many schools use different percent bands, plus/minus rules, or weighted scales. Always follow your official school or university policy.
Typical letter → points (unweighted 4.0)
| Letter | Typical % range | Unweighted points | Notes |
|---|---|---|---|
| A+ | 97–100 | 4.0 (or 4.3) | Some schools cap A+ at 4.0; others use 4.3 |
| A | 93–96 | 4.0 | Common top unweighted value |
| A− | 90–92 | 3.7 | Plus/minus not used everywhere |
| B+ | 87–89 | 3.3 | |
| B | 83–86 | 3.0 | |
| B− | 80–82 | 2.7 | |
| C+ | 77–79 | 2.3 | |
| C | 73–76 | 2.0 | |
| C− | 70–72 | 1.7 | |
| D+ | 67–69 | 1.3 | |
| D | 63–66 | 1.0 | |
| D− | 60–62 | 0.7 | Some schools stop at D = 1.0 |
| F | Below 60 | 0.0 | Failing cutoff varies |
Final grade needed (quick formula)
When a final exam is weight w (as a fraction, e.g. 0.30 for 30%), current course grade is current, and target overall is desired:
needed = (desired − current × (1 − w)) ÷ w
Example: want 90, sitting at 88, final is 20% → needed = (90 − 88 × 0.8) ÷ 0.2 = 98. If the result is over 100, that target may be unreachable under the stated weights — check with your syllabus.

Frequently asked questions
What is the difference between weighted and unweighted GPA?
Unweighted GPA usually maps letters to a 0–4.0 scale (A = 4.0). Weighted GPA may add extra points for honors, AP, or IB (for example 4.5 or 5.0 for an A). Your transcript policy defines the boost — online charts are only typical defaults.
Is A+ worth 4.0 or 4.3?
Both exist. Many U.S. high schools treat A and A+ as 4.0 unweighted. Some colleges use 4.3 (or similar) for A+. Never assume — use the scale printed in your school or registrar handbook.
What is semester GPA vs cumulative GPA?
Semester (or term) GPA is the credit-weighted average of courses in that term only. Cumulative GPA combines all graded terms: total quality points ÷ total graded credits. A strong later semester raises cumulative GPA only in proportion to its credit share.
