US letter grade to GPA scale (4.0)
This calculator uses the standard US 4.0 scale used by most high schools and colleges.
| Grade | Points | Grade | Points |
|---|---|---|---|
| A | 4.0 | C | 2.0 |
| A− | 3.7 | C− | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B− | 2.7 | F | 0.0 |
| C+ | 2.3 |
Grade Points for a course = Grade Points × Credit Hours
Weighted mode: Honors and AP courses get +0.5 points (for example, an A in an AP class counts as 4.5 instead of 4.0). An F earns no bonus. Switch to Weighted at the top of the calculator and set the Class type for each course.
Worked example: 3 credits of A (12 pts) + 3 credits of B (9 pts) + 4 credits of C (8 pts) = 29 points ÷ 10 credits = 2.90 GPA. If that A is an Honors/AP class in weighted mode: 30.5 ÷ 10 = 3.05 GPA. Try it with “Load Example.”
How it works
Step by step
- Add a course — type its name, credit hours (most college classes are 3 credits), and the letter grade you earned.
- Pick the mode — Unweighted for the plain 4.0 scale, or Weighted if your school rewards Honors/AP classes.
- Mark Honors/AP — in weighted mode, set Class type to Honors or AP to add the +0.5 bonus.
- Read your result — GPA, total credits, and total grade points update instantly as you type.
What counts as a good GPA?
3.7 – 4.0: Excellent — A range, competitive for top colleges and honors programs.
3.3 – 3.6: Strong — above average at most schools.
3.0 – 3.2: Good — solid B average, meets most college requirements.
2.0 – 2.9: Average to below — worth a plan to improve.
Below 2.0: At risk — many schools place students on academic probation below 2.0.
Frequently asked questions
How is GPA calculated?
For each course, multiply the grade points (from the 4.0 scale) by the credit hours. Add all those results together to get total grade points, then divide by your total credit hours. Example: 29 grade points ÷ 10 credits = 2.90 GPA.
What is the difference between weighted and unweighted GPA?
An unweighted GPA maxes out at 4.0 and treats every class equally. A weighted GPA rewards harder classes — in this calculator Honors and AP courses earn +0.5 points, so an A in an AP class counts as 4.5. Many high schools report both.
What GPA do I need for college admissions in the USA?
It varies widely. Many public universities accept students around a 3.0, selective schools often look for 3.5+, and Ivy League schools typically admit students at 3.8–4.0 (unweighted). Admissions also weigh course rigor, essays, activities, and test scores — GPA is only one part.
How can I raise my GPA?
Focus on the classes with the most credits first, since they move your GPA the most. Retaking a failed class (if your school replaces the grade), choosing a balanced course load, using tutoring and office hours, and protecting your grades in core subjects usually helps fastest. Use the “Previous GPA” fields above to test how a strong semester would change your cumulative GPA.
Does an F affect my GPA?
Yes. An F earns 0 grade points but its credits still count in the denominator, so it lowers your GPA significantly. In weighted mode an F earns no Honors/AP bonus in this calculator.
Is my data saved or shared?
No. Everything runs instantly in your browser on this page. There is no login, no account, and your courses and grades are not saved or sent anywhere — they disappear when you close the tab.
Why might my school’s GPA differ from this result?
Schools use different rules: some don’t use plus/minus grades, some weight AP by +1.0 instead of +0.5, some cap weighted GPA at 5.0, and some exclude electives or pass/fail classes. Treat this result as a close estimate and check your official transcript for the exact figure.
