Your Grade Point Average (GPA) on the 4.0 scale is the number most high schools, colleges, and graduate programs use to summarize your academic record. This free 4.0 GPA calculator uses the classic whole-letter scale — A = 4, B = 3, C = 2, D = 1, F = 0 — with no plus or minus tiers. That is the version your school almost certainly prints on a transcript if it does not offer honors or AP weighting, and it is the scale admissions officers expect when they ask for your GPA out of 4.0.
Unlike a plain average of your letters, this calculator weights each grade by its credit hours, so a 4-credit lecture pulls your result more than a 1-credit seminar. Type the grade points for each course, enter its credit hours, and your unweighted GPA updates instantly.
How to Use
- Start with the Course 1 row. Type the point value of the grade you earned as a number — the form takes points, not letters. On this whole-letter scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. There are no plus or minus tiers.
- Enter the Course 1 Credits the class is worth. A typical lecture is 3 or 4 credits; a lab, seminar, or physical-education class is often 1.
- Repeat for Course 2, and continue through Courses 3, 4, and 5 if you have more classes. There are five fixed rows; for any row you do not need, leave its credits at 0 and it is skipped.
- Read the result card. The highlighted number is your GPA (4.0 scale), followed by the Total Credits counted and the Total Grade Points the points add up to.
The math is deliberately transparent. For each course you contribute grade points times credit hours. Sum those products into total grade points, sum the credit hours, then divide one by the other. A course worth zero credits — an audit or pass-fail class — is skipped in the division, so it neither raises nor lowers your average. The calculator does not guess your letter grade for you; enter the point value from the mapping table below, and the GPA itself is always a plain number on the 0–4 scale.
The 4.0 GPA Formula
Every US registrar teaches the same credit-weighted average:
GPA = Σ (points[grade] × credit hours) ÷ Σ credit hours
On the whole-letter scale, points are simply A = 4, B = 3, C = 2, D = 1, F = 0. Worked example: an A in a 3-credit class contributes 4 × 3 = 12 grade points; a B in another 3-credit class contributes 3 × 3 = 9. Total grade points = 12 + 9 = 21; total credits = 6; GPA = 21 ÷ 6 = 3.50. That is a solid B average and right around the common Cum Laude threshold.
Notice what happens when credits are uneven. If the A were worth 4 credits and the B only 2, you would get (16 + 6) ÷ 6 = 3.67. The heavier grade dominates, which is exactly why colleges ask for both GPA and credit hours together rather than trusting a flat letter average.
On a 0-to-100 percentage scale the rough bands are: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, and F = below 60%. A 3.5 GPA usually sits in the top 15–20% of a graduating class, while 3.8 and above is commonly required for Latin honors and competitive graduate programs.
How Letter Grades Map to Points
| Letter | Points | Typical % band |
|---|---|---|
| A | 4.0 | 90–100% |
| B | 3.0 | 80–89% |
| C | 2.0 | 70–79% |
| D | 1.0 | 60–69% |
| F | 0.0 | below 60% |
Some colleges add plus/minus tiers (A− = 3.7, B+ = 3.3, and so on). If your school uses those, treat an A− as an A and a B+ as a B when entering grades here, or use a plus/minus GPA calculator for a more precise figure. The whole-letter scale is the floor that every other scale is built on.
Examples
Example 1 — A normal semester. A student takes four classes: A in English (3 credits), B in Biology (4 credits), C in History (3 credits), and B in Algebra (3 credits). Grade points = 4×3 + 3×4 + 2×3 + 3×3 = 12 + 12 + 6 + 9 = 39. Total credits = 13. GPA = 39 ÷ 13 = 3.00, a straight B average.
Example 2 — The classic 3.5. An A in a 3-credit class (12 points) and a B in another 3-credit class (9 points) give 21 points over 6 credits = 3.50. This is the number many scholarships use as a minimum cutoff, and it lands near 85% on the rough percent scale.
Example 3 — A failing grade hurts. If one 3-credit class is an F (0 points) instead of a B, the same transcript drops from 39 points to 30 points over 13 credits — a GPA of 2.31 instead of 3.00. One failed course can move your average by nearly a full point, which is why early recovery matters.
FAQ
What is a 4.0 GPA?
A 4.0 GPA is an unweighted Grade Point Average on the classic scale where A = 4, B = 3, C = 2, D = 1, and F = 0. It is called unweighted because no extra points are added for honors, AP, or IB classes, and every course contributes proportionally to its credit hours.
How do I calculate my GPA on a 4.0 scale?
Multiply each grade's point value by its credit hours, add all those products together, then divide by the sum of your credit hours. For example, an A (4 points) in a 3-credit course plus a B (3 points) in a 3-credit course gives (12 + 9) ÷ 6 = 3.5.
Is a 3.5 GPA good?
Yes. A 3.5 on the 4.0 scale is roughly a B+ average and usually places you in the top 15–20% of a graduating class. It meets the typical Cum Laude cutoff at many schools and is a competitive starting point for many graduate programs, though top-tier schools often expect 3.7 or higher.
What is the difference between weighted and unweighted GPA?
An unweighted GPA caps every A at 4.0 regardless of course difficulty. A weighted GPA adds bonus points — often +0.5 for honors and +1.0 for AP or IB — so an A in a tough class can be worth 4.5 or 5.0. This calculator is unweighted and uses the plain 4.0 scale.
Do pass-fail or audit classes count?
Usually no. A course worth 0 credit hours, or graded only pass/fail, contributes no grade points and no credits, so it is left out of the division. Entering a 0-credit row is safe; the calculator simply skips it.
How do I raise my GPA next semester?
Add more credit hours of strong grades. A single A in a 3-credit course moves a 15-credit semester GPA by about 0.6 points if the other courses are all Bs, while a D in the same slot drags it down by about 0.6. Enter your planned courses here and experiment with a grade before the semester starts.
