What is a GPA?
Your GPA — grade point average — condenses every grade you have earned into a single number, almost always between 0.0 and 4.0. Each letter grade is converted to grade points on a fixed scale (an A is 4.0, a B is 3.0, and so on), and those points are averaged across your courses, weighted by how many credit hours each course carries. It is the figure that appears on your transcript and the one colleges, scholarship committees, honor societies, and many employers look at first. Being able to recalculate it in seconds puts you in control of the decisions that depend on it.
The GPA scale at a glance
Nearly every US school converts letter grades to grade points on the 4.0 scale below. Percentages map to a letter first, then to points; exact cutoffs vary slightly between schools, so treat the ranges as the common standard.
| Letter | Percentage | Grade points |
|---|---|---|
| A+ / A | 93–100 | 4.0 |
| A- | 90–92 | 3.7 |
| 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 | 63–66 | 1.0 |
| F | Below 60 | 0.0 |
Plus and minus grades shift the value by about 0.3 (a B+ is 3.3, a B- is 2.7). On the standard scale an A+ and an A are both 4.0, so an A+ does not lift you above a 4.0 — though a few schools award 4.3. For the complete letter, percentage and weighted tables, see the GPA scale; to turn a raw percentage into a GPA, use the percentage-to-GPA converter.
How your GPA is calculated
GPA is a credit-weighted average of your grade points. In one line:
GPA = (sum of grade points × credits) ÷ (total credits)
Multiply each course’s grade points by its credit hours to get its quality points, add the quality points across every course, then divide by your total credits. For example, an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class give (4.0×3 + 3.0×4) ÷ 7 = 3.43 — the 4-credit class pulls the average toward its grade because it carries more weight. The calculator above runs this live as you type; for the full method with more worked examples, read how to calculate your GPA.
No credit hours to hand? Switch off the Credits toggle and every graded course counts equally, so your GPA becomes the simple average of your grade points — useful for a quick estimate or a school that does not use credits.
Which GPA calculator do you need?
The tool above adapts to each situation, and every mode also has a dedicated page with its own worked example and tips:
- College GPA — credit-weighted across your courses and semesters, the way a registrar computes it.
- High school GPA — weighted or unweighted, with the Honors and AP/IB bonuses that can push a weighted GPA above 4.0.
- Cumulative GPA — every semester pooled into one overall figure; add your current GPA and credits to project where a new term lands.
- Class grade and final grade — build a single class grade from your assignments, or find the score you need on the final to hit a target.
- Weighted grade — combine categories that each count for a different share of your grade.
Weighted vs. unweighted, and GPAs above 4.0
An unweighted GPA caps every course at 4.0. A weighted GPA rewards harder courses with bonus points — commonly +0.5 for Honors and +1.0 for AP or IB — so an A in an AP class can be worth 5.0 and a weighted GPA can climb past 4.0. Turn on the Weighted toggle and set each course’s type to compare the two. High schools weight far more often than colleges; the high school calculator covers the details, and the weighted grade calculator handles weighted categories inside a single class.
What is a good GPA?
It depends on your goals, but as a rough guide on the 4.0 scale: 3.0 is a solid B average, 3.5+ is competitive for scholarships, internships and graduate programs, and 3.7+ generally reaches Latin honors (cum laude and above). Most schools require a 2.0 to stay in good academic standing. Rigor matters as much as the number — a 3.6 packed with AP or Honors courses reads differently from a 3.6 of easier ones — and selective programs often recalculate GPA their own way. Treat it as a checkpoint, not a verdict, and use the guide to raising your GPA if you want to move it.
