How GPA is calculated

GPA = total quality points ÷ total credits, where quality points = grade points × course credits. This calculator uses the standard US 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0). Some schools weight honors/AP courses higher — check your institution's policy.

Instant insight

Semester GPA 4.00 — first-class territory on most scales
Built from 48.0 quality points. GPA is weighted by credit hours, not a plain average: a four-credit course moves it twice as much as a two-credit one.
That is why rescuing a GPA works better through a heavily weighted course than through several small ones.
Grade scales are not standard between institutions
A 4.0 scale, a 4.3 scale with A+, weighted honours points and different percentage boundaries all coexist.
Use your own institution's published scale — a GPA calculated on the wrong one is not comparable to anything.

Everyday Uses

Scholarship eligibility

Most scholarships have GPA cutoffs — know exactly where you stand before applying.

Semester planning

Work out what grades you need this term to pull your cumulative GPA above a target.

Grad school applications

Convert your grades into the GPA figure applications ask for, weighted correctly by credits.

Converting between grading systems

Applications abroad often want a 4.0-scale figure even when your institution marks in percentages, a 20-point scale or letter bands.

What this semester has to deliver

Work backwards from the cumulative GPA you need to the grades required, and find out early whether the target is still mathematically reachable.

Frequently Asked Questions

How is GPA calculated?

GPA = total quality points ÷ total credit hours. Each letter grade has a point value on the 4.0 scale (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, C = 2.0, D = 1.0, F = 0). Multiply each course's points by its credit hours to get quality points, sum them, then divide by total credits. Example: an A in a 3-credit course (12.0 points) and a B in a 4-credit course (12.0 points) gives 24 ÷ 7 = 3.43 GPA.

How do I calculate my cumulative GPA?

Combine all completed coursework: cumulative GPA = (previous quality points + new quality points) ÷ (previous credits + new credits). If you have a 3.42 GPA over 45 credits and earn a 3.80 over 15 new credits, your cumulative GPA is (3.42×45 + 3.80×15) ÷ 60 = 3.52. Enter your prior GPA and credits in this calculator to get it automatically.

What is a good GPA?

On the 4.0 scale: 3.7+ is excellent (A− average, competitive for top graduate programs), 3.5–3.7 is very good (dean's list territory at many schools), 3.0–3.5 is good (meets most graduate school and employer thresholds), and 2.0 is typically the minimum to stay in good academic standing. Context matters — GPA expectations vary by school, major, and program difficulty.

What is the difference between weighted and unweighted GPA?

Unweighted GPA uses the standard 4.0 maximum regardless of course difficulty. Weighted GPA (common in US high schools) awards extra points for honors, AP, or IB courses — often A = 5.0 in an AP class — so weighted GPAs can exceed 4.0. Colleges typically recalculate applicants' GPAs using their own method. This calculator uses the unweighted 4.0 scale.
