Already have a GPA to factor in?

Leave both at 0 if you're just calculating this semester on its own. Fill these in to see your new overall cumulative GPA after adding the courses above.

Quick answers

What grade scale does this use?

Standard US 4.0 scale: 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. Some schools use slightly different scales (a few give A+ a 4.3) — check your school's official policy if you need an exact match.

How is weighted GPA calculated?

Each course's grade points are multiplied by its credit hours to get "quality points." All quality points are summed and divided by total credit hours. A 4-credit A (4.0) counts more than a 1-credit A, which is why higher-credit courses affect your GPA more.

How do I combine this with my existing GPA?

Enter your current cumulative GPA and total credit hours earned so far in the card above. The calculator treats your prior GPA as if it were one large course worth that many credits, then blends it with the new courses to give your updated overall GPA.

How to use this calculator

GPA is quality points divided by credit hours. The calculator builds that fraction from your course list, so the only real work is entering each course accurately.

  1. Add each course with its letter grade and its credit hours. A four-credit course carries more weight than a one-credit course, which is the point of the credit weighting.
  2. Check the grade points against your registrar's scale. This page uses a common plus/minus table, and not every school uses the same one.
  3. Leave pass/fail and transfer-credit courses out. They usually add credits without points, and including them would drag the average down incorrectly.
  4. Optionally enter your prior cumulative GPA and prior credit hours. The tool blends them by credit weight to produce a cumulative figure.
  5. Change one grade and watch the term GPA move. That is the fastest way to see what a single course is worth.

A worked example: three courses plus a prior average

An A in a 4-credit course is 4.0 × 4, or 16 quality points. A B in 3 credits is 3.0 × 3, or 9. A C+ in 4 credits is 2.3 × 4, or 9.2. Total quality points are 34.2 across 11 credits, which is a term GPA of 3.11.

Now blend in a prior 3.45 across 45 credits. That prior work is 3.45 × 45, or 155.25 points. Combined, 189.45 points across 56 credits gives a cumulative GPA of 3.38.

The lesson in those two numbers: a good term barely moves a long transcript. The same 3.11 term against 12 prior credits instead of 45 would land near 3.34 rather than 3.38. The more history you have, the more inertia it carries — which is encouraging if you had a rough first year and discouraging if you are trying to lift a strong one.

What your results mean

The number is your school's arithmetic on your school's scale, and only the second part is uncertain. A B+ is worth 3.3 here; some registrars use 3.33, some do not use plus or minus at all, and some count an A+ above 4.0. If your transcript disagrees with this result, the scale is almost always the reason rather than the arithmetic.

Term GPA describes one stretch of work. Cumulative GPA describes everything, weighted by credits. Employers and graduate programs usually ask for the cumulative figure, and many want it on a specific scale, so state the scale when you report it.

Withdrawals, incompletes, and repeated courses are not modeled. A repeated course may replace the old grade or average with it, depending on the institution, and that single rule can move a cumulative GPA by more than a semester of effort.

Nothing here converts between scales. A 3.8 on a 4.0 scale is not a specific percentage, and the conversion tables in circulation vary enough that using one would be a guess dressed as a number.

Frequently asked questions

How is GPA calculated?

Each grade is converted to grade points, multiplied by the course's credit hours to get quality points, then the total quality points are divided by total credit hours. That is why a 4-credit course counts twice as much as a 2-credit one.

Why doesn't this match my transcript?

Almost always a different grade-point scale, or a rule about repeated courses and pass/fail credits. Check your registrar's published table against the one used here.

Should I include courses I'm taking now?

Only if you have a grade to enter. An in-progress course with no grade would need a placeholder, and a guessed grade produces a guessed GPA.

What about a transfer GPA?

Transfer credits usually appear as credits without quality points, so they raise the credit total without raising the average. Leave them out unless your school folds them in, which is uncommon.

Does a W affect my GPA?

A withdrawal typically carries no grade points and no effect on the average, though it may affect satisfactory academic progress for financial aid. The rules are institutional.

Is a 3.0 good?

It depends entirely on the context: the school, the major, and what the number is for. A 3.0 clears many graduate-program minimums and falls short of others. This calculator reports the number and has no opinion on it.
