How are letter grades converted to points?

The standard US scale maps A to 4.0, A- to 3.7, B+ to 3.3, B to 3.0, and so on down to F at 0.0. An A+ is usually capped at 4.0 in an unweighted GPA, which is the convention this tool uses.

What does credit-weighted mean?

Each course's grade points are multiplied by its credit hours before averaging, so a 4-credit course influences your GPA twice as much as a 2-credit course. The GPA is total quality points divided by total credits, not a simple average of grades.

Does an A+ count as more than 4.0?

On most unweighted 4.0 scales an A+ is capped at 4.0, the same as an A. Some institutions award 4.3 for an A+, but the standard unweighted scale tops out at 4.0, which is what this calculator applies.

How do I compute a cumulative GPA?

Enter every course from all terms you want included, each with its credit hours. The credit-weighted formula naturally produces a cumulative GPA across multiple semesters when all courses are listed together.

What about pass or fail courses?

Pass or fail courses normally carry no grade points and are excluded from GPA. Simply leave those courses out of this calculator, since including them with an arbitrary grade would distort your average.

What is the US 4.0 GPA Calculator?

Enter each course letter grade (A+ through F) and its credit hours to compute your grade point average on the standard US 4.0 scale, using credit-weighted averaging so heavier courses count proportionally more toward the final GPA.

The US grade point average converts letter grades into a 0 to 4.0 numeric scale and averages them by credit hours. This calculator does the credit weighting for you so heavier courses count proportionally toward your GPA.

How it works

Each grade maps to a point value, is weighted by credits, and the weighted points are averaged:

quality points = grade points × credit hours   (per course)
GPA            = Σ quality points / Σ credit hours

A+/A 4.0  A− 3.7  B+ 3.3  B 3.0  B− 2.7
C+ 2.3    C 2.0   C− 1.7  D+ 1.3 D 1.0  F 0.0

Because the divisor is total credits rather than course count, a high grade in a big course lifts your GPA more than the same grade in a small one.

Worked example

Two courses — an A (4.0) worth 4 credits and a C (2.0) worth 2 credits — give (4.0×4 + 2.0×2) / (4+2) = (16 + 4) / 6 ≈ 3.33, which is higher than a simple average of (4.0 + 2.0) / 2 = 3.0 because the A carries more credits.

Now add a third course — a B+ (3.3) worth 3 credits: (4.0×4 + 2.0×2 + 3.3×3) / (4+2+3) = (16 + 4 + 9.9) / 9 = 29.9 / 9 ≈ 3.32

Even though all three courses have different grades and credit values, the calculator handles the weighting automatically.

What the GPA thresholds mean in practice

US academic institutions use GPA benchmarks for a range of decisions:

2.0 / C average: typically the minimum to remain enrolled and to graduate from an undergraduate programme; falling below this triggers academic probation at most schools
3.0 / B average: the common floor for graduate school admission (many Master’s and PhD programmes require a 3.0 minimum)
3.5: often the threshold for graduating with honours (cum laude); Latin honours categories vary by institution but 3.5+ is a common benchmark for cum laude
3.7 or 3.8: typically required for magna cum laude
3.9–4.0: summa cum laude at most institutions
3.5+: typically required to maintain merit scholarships at many universities

Weighted vs. unweighted GPA

At the US college level, GPA is almost always unweighted — every course is treated the same regardless of difficulty, and A+ is capped at 4.0. This is what this calculator computes.

At US high schools, some schools offer a weighted GPA where AP (Advanced Placement) or IB courses award up to 5.0 points for an A. High school weighted GPA is not used in college admissions the same way — most admissions offices recalculate a standardised GPA from the transcript using their own rubric. For college and graduate applications, the GPA that matters is the college-level unweighted GPA on a 4.0 scale, which is what this tool produces.

Handling pass/fail and audit courses

Pass (P) and Fail (F) under a pass/fail grading option typically carry no grade points in GPA calculations. The credit hours from a passed P/F course are awarded and count toward graduation but are excluded from the GPA denominator. An audited (AU) course earns neither credit nor a grade and is fully excluded from GPA. Leave these courses out of this calculator; including a P with an arbitrary grade point value would inflate or distort your average incorrectly.
