GPA Calculator

Credit hours × grade points = your GPA

Nothing you enter is sent to a server — the math runs in your browser as you type. Each row's grade point is multiplied by its credit hours, and the results are summed and divided by total credit hours:

The dropdown uses the standard US mapping: A and A+ both equal 4.0, A− is 3.7, B+ is 3.3, B is 3.0, down to F at 0.0. Some institutions cap A+ below 4.0 instead of treating it as equal to A — if yours does, the calculator will read slightly high for an A+ heavy transcript.

Averaging five courses into one GPA

• Calculus II — 4 credits — B (3.0)
• Intro to Economics — 3 credits — A− (3.7)
• English Composition — 3 credits — A (4.0)
• General Chemistry — 4 credits — B+ (3.3)
• Chemistry Lab — 1 credit — A (4.0)

(3.0 × 4) + (3.7 × 3) + (4.0 × 3) + (3.3 × 4) + (4.0 × 1) = 12 + 11.1 + 12 + 13.2 + 4 = 52.3
52.3 ÷ 15 credits = 3.49 GPA.

Why a high-credit course moves your GPA more than a low-credit one

An A in the 4-credit Chemistry course pulls the total up more than the A in the 1-credit lab does, even though both are worth 4.0 individually — the credit-hours field is what makes that difference. When you're choosing between electives, a guaranteed A in a high-credit class does more for your GPA than the same A in a one-credit seminar.

Scales that don't match this calculator

• Straight-letter grading. Some schools don't use +/− modifiers — A is always 4.0, B is always 3.0. Just skip the +/− options in the dropdown.
• 10-point scales. Indian, Pakistani, and many European universities use a 10-point scale instead of 4.0. Don't enter a 10-point grade point directly here — use the SGPA to CGPA tool instead.
• Honors-weighted GPAs. Some US high schools weight AP, IB, or Honors courses on a 5.0 scale, which is how a GPA above 4.0 happens. This calculator doesn't apply that weighting.
• Percentage-only transcripts. If your university reports percentages instead of letter grades, use Marks Percentage or Percentage to CGPA instead.

Things that quietly throw off this calculator

1. Entering pass/fail courses. A P/F course almost never affects GPA — leave it out of the rows entirely rather than guessing a grade for it.
2. Guessing at repeated courses. Some universities replace the lower grade when you retake a course; others average both attempts. Enter it the way your school's policy actually works, not the way that's more flattering.
3. Estimating credit hours. Credit hours are printed on your transcript and course catalog — don't guess. Even a one-credit error can shift a borderline GPA enough to matter.

What your GPA means for honors and grad school

3.7–4.0 typically corresponds to magna or summa cum laude at most US universities. 3.3–3.7 is honors-tier and competitive for most graduate programs. 3.0–3.3 meets the baseline for most jobs and progression requirements. Below 2.0 is generally an academic-probation zone — check your school's specific threshold if you're near it.

Using this before you commit to a course load

Enter your current courses and try different grade assumptions in each row to see which one moves your GPA the most before you decide where to focus your study time. Pair it with the final grade calculator to see the minimum exam score you need in a given course to keep your GPA above a target.

When the calculator and your transcript won't match exactly

Your official transcript is the authoritative number. A difference of 0.01–0.02 is almost always rounding. A bigger gap usually means an excluded transfer credit, a repeated-course policy, or a non-standard grading scale your registrar applied that this calculator doesn't know about.
