GPA Calculator
Calculate your semester or cumulative grade point average on the standard 4.0 scale — just enter your grades and credit hours.
How the GPA Calculator works
The GPA Calculator computes a credit-weighted grade point average: courses worth more credit hours count proportionally more toward your GPA. Enter each course's letter grade and credit hours, and the tool totals your quality points and divides by your total graded credits.
It works for a single semester or for your full cumulative record — just add every course you want included. Pass/Fail, Withdraw and other non-graded marks should be left out, since they do not carry grade points.
Formula & grading scale
Every grade maps to a point value. Multiply each grade's value by the course's credit hours to get its quality points, sum them, and divide by total credits:
GPA = Σ(grade value × credit hours) ÷ Σ(credit hours)
The standard 4.0 uses this grade scale:
| Grade | Points | Grade | Points |
|---|---|---|---|
| A | 4 | A- | 3.7 |
| B+ | 3.3 | B | 3 |
| B- | 2.7 | C+ | 2.3 |
| C | 2 | C- | 1.7 |
| D+ | 1.3 | D | 1 |
| D- | 0.7 | F | 0 |
This is the unweighted scale used by most U.S. colleges. Honors and AP courses are not given extra points here; for a weighted high-school GPA, add the bonus to each grade before entering it.
Step-by-step example
Suppose you took three courses in a term:
- Biology — grade A (4.0) × 4 credits = 16.0 quality points.
- Calculus — grade B+ (3.3) × 3 credits = 9.9 quality points.
- English — grade B (3.0) × 3 credits = 9.0 quality points.
Total quality points = 16.0 + 9.9 + 9.0 = 34.9. Total credits = 4 + 3 + 3 = 10. Your GPA = 34.9 ÷ 10 = 3.49 on the 4.0 scale. (Exact point values depend on the scale shown above.)
What is a good GPA?
On the 4.0 scale, a GPA of 3.0 (a solid B average) is widely considered respectable, 3.5 and above is strong, and 3.8+ is excellent. Context matters, though — course difficulty and your goals shape what "good" means for you. If you need a percentage equivalent for an application, the GPA to Percentage Calculator converts it in one step.
How to raise your GPA
Your highest-credit courses move your average the most, so prioritise them. Track your running quality points as you enter grades above, then model a target by adjusting a grade or two. For the full mechanics behind the numbers, read our guide on how GPA is calculated.
Weighted vs. unweighted GPA
This calculator is unweighted, capping every course at 4.0. A weighted GPA adds bonus points for honors, AP or IB courses — often +0.5 or +1.0 — so it can exceed 4.0. To get a weighted result, add the bonus to each grade value before entering it. University scales differ too; see our Rutgers or Indiana University GPA calculators for examples.
Why use our GPA Calculator?
This tool is free, works on any device, and keeps your data private by running entirely in your browser. Use it to check a single term, combine several semesters into a cumulative GPA, or test a "what-if" grade before finals. If you need a percentage for an application, pair it with the GPA to Percentage Calculator; going the other way, the Percentage to GPA Calculator converts a percentage back to the 4.0 scale.
Frequently asked questions
Do Pass/Fail or Withdraw grades count?
No. Pass/Fail (P/S), Withdraw (W), Incomplete (I) and similar marks carry no grade points and are excluded from the GPA. Only enter courses that received a letter grade on the scale.
How are repeated courses handled?
By default this tool includes every attempt you enter, which matches how most cumulative GPAs are calculated. If your institution has a grade-forgiveness or repeat policy that drops the original attempt, simply leave the forgiven attempt out of the form.
What is the difference between weighted and unweighted GPA?
An unweighted GPA caps every course at 4.0. A weighted GPA adds bonus points for honors, AP or IB courses (often +0.5 or +1.0). This tool is unweighted by default; you can enter adjusted values manually for a weighted result.
How do I calculate a cumulative GPA across semesters?
Enter every graded course from all the semesters you want included. The calculator divides your total quality points by your total credits, which is exactly how a cumulative GPA is found.
Why use credit hours instead of a simple average?
Courses are not all the same size. A 4-credit course influences your GPA more than a 1-credit course, so grades are weighted by credit hours rather than averaged equally.
